Field Generator is a module to help you create random character strings and automatically assign them to one or multiple fields of your choice when a page is created. When setup, it will automatically do so whether you create a page through the administration panel or through code, meaning you don’t need to set $page->name or any other field of your choice, it just works automagically. Field Generator uses PHP’s openssl_random_pseudo_bytes() function to generate its random strings. It thus has both PHP >= 5.3.0 and OpenSSL as dependencies. Usage After installation, add rules through Setup > Field Generator. That’s it! Rules only run when first creating the page. For more information : https://github.com/plauclair/FieldGenerator Release : Version 0.9.0 This is the initial release. This is near stable and you shouldn’t be too worried to use it in production. Here is a screencast on how to use it.7 points

Super Smartypants is a ProcessWire textformatter module which adds support for languages. It also allows you to set the different Smartypants Typographer parser attributes to customize which rules apply and fixes some bugs. Super Smartypants requires the language module. Usage After installation, add /site/modules/TextformatterSuperSmartypants/smartypants.php to your language translations. To enable Super Smartypants for a language, set the Smartypants attributes field to 1 (or see below for details), otherwise to disable leave the field empty. Change default strings according to your masterful typographic knowledge. Documentation and download : https://github.com/plauclair/SuperSmartypants4 points

The problem with theme switching indeed exists on latest dev versions, I'm also using PW for production in Windows environment and in 2.4.0 switching is working fine. I'll check every suggestion and posted question when I get home from holiday (tommorow) because I don't have my working computer with me...2 points

--------------------------------------------------------------------------------------------------------------------------------- when working with PW version 2.6+, please use Pim2, not Pim! read more here on how to change from the older to the newer version in existing sites --------------------------------------------------------------------------------------------------------------------------------- PageImage Manipulator, API for version 1 & 2 The Page Image Manipulator is a module that let you in a first place do ImageManipulations with your PageImages. - And in a second place there is the possibility to let it work on any imagefile that exists in your servers filesystem, regardless if it is a 'known PW-image'. The Page Image Manipulator is a Toolbox for Users and Moduledevelopers. It is written to be as close to the Core ImageSizer as possible. Besides the GD-filterfunctions it contains resize, crop, canvas, rotate, flip, sharpen, unsharpMask and 3 watermark methods. How does it work? You can enter the ImageManipulator by calling the method pim2Load(). After that you can chain together how many actions in what ever order you like. If your manipulation is finished, you call pimSave() to write the memory Image into a diskfile. pimSave() returns the PageImage-Object of the new written file so we are able to further use any known PW-image property or method. This way it integrates best into the ProcessWire flow. The three examples above put out the same visual result: a grayscale image with a width of 240px. Only the filenames will slightly differ. You have to define a name-prefix that you pass with the pimLoad() method. If the file with that prefix already exists, all operations are skipped and only the desired PageImage-Object gets returned by pimSave(). If you want to force recreation of the file, you can pass as second param a boolean true: pim2Load('myPrefix', true). You may also want to get rid of all variations at once? Than you can call $pageimage->pim2Load('myPrefix')->removePimVariations()! A complete list of all methods and actions are at the end of this post. You may also visit the post with tips & examples for users and module developers. How to Install Download the module Place the module files in /site/modules/PageImageManipulator/ In your admin, click Modules > Check for new modules Click "install" for PageImageManipulator Done! There are no configuration settings needed, just install and use it. Download (version 0.2.0) get it from the Modules Directory History of origins http://processwire.com/talk/topic/3278-core-imagemanipulation/ ---------------------------------------------------------------------------------------------------------- Page Image Manipulator - Methods * pimLoad or pim2Load, depends on the version you use! pimLoad($prefix, $param2=optional, $param3=optional) param 1: $prefix - (string) = mandatory! param 2: mixed, $forceRecreation or $options param 3: mixed, $forceRecreation or $options return: pim - (class handle) $options - (array) default is empty, see the next method for a list of valid options! $forceRecreation - (bool) default is false It check if the desired image variation exists, if not or if forceRecreation is set to true, it prepares all settings to get ready for image manipulation ------------------------------------------------------------------- * setOptions setOptions(array $options) param: $options - (array) default is empty return: pim - (class handle) Takes an array with any number valid options / properties and set them by replacing the class-defaults and / or the global config defaults optionally set in the site/config.php under imageSizerOptions or imageManipulatorOptions. valid options are: quality = 1 - 100 (integer) upscaling = true | false (boolean) cropping = true | false (boolean) autoRotation =true | false (boolean) sharpening = 'none' | 'soft' | 'medium' | 'strong' (string) bgcolor = (array) css rgb or css rgba, first three values are integer 0-255 and optional 4 value is float 0-1, - default is array(255,255,255,0) thumbnailColorizeCustom = (array) rgb with values for colorize, integer -255 - 255 (this can be used to set a custom color when working together with Thumbnails-Module) outputFormat = 'gif' | 'jpg' | 'png' (Attention: outputFormat cannot be specified as global option in $config->imageManipulatorOptions!) set {singleOption} ($value) For every valid option there is also a single method that you can call, like setQuality(90), setUpscaling(false), etc. ------------------------------------------------------------------- * pimSave pimSave() return: PageImage-Object If a new image is hold in memory, it saves the current content into a diskfile, according to the settings of filename, imagetype, targetFilename and outputFormat. Returns a PageImage-Object! ------------------------------------------------------------------- * release release() return: void (nothing) if you, for what ever reason, first load image into memory but than do not save it, you should call release() to do the dishes! ? If you use pimSave() to leave the ImageManipulator, release() is called automatically. ------------------------------------------------------------------- * getOptions getOptions() return: associative array with all final option values example: ["autoRotation"] bool(true) ["upscaling"] bool(false) ["cropping"] bool(true) ["quality"] int(90) ["sharpening"] string(6) "medium" ["targetFilename"] string(96) "/htdocs/site/assets/files/1124/pim_prefix_filename.jpg" ["outputFormat"] string(3) "jpg" get {singleOption} () For every valid option there is also a single method that you can call, like getQuality(), getUpscaling(), etc. See method setOptions for a list of valid options! ------------------------------------------------------------------- * getImageInfo getImageInfo() return: associative array with useful informations of source imagefile example: ["type"] string(3) "jpg" ["imageType"] int(2) ["mimetype"] string(10) "image/jpeg" ["width"] int(500) ["height"] int(331) ["landscape"] bool(true) ["ratio"] float(1.5105740181269) ["bits"] int(8) ["channels"] int(3) ["colspace"] string(9) "DeviceRGB" ------------------------------------------------------------------- * getPimVariations getPimVariations() return: array of Pageimages Collect all pimVariations of this Pageimage as a Pageimages array of Pageimage objects. All variations created by the core ImageSizer are not included in the collection. ------------------------------------------------------------------- * removePimVariations removePimVariations() return: pim - (class handle) Removes all image variations that was created using the PIM, all variations that are created by the core ImageSizer are left untouched! ------------------------------------------------------------------- * width width($dst_width, $sharpen_mode=null) param: $dst_width - (integer) param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you prioritize the width, like with pageimage. Additionally, after resizing, an automatic sharpening can be done with one of the three modes. ------------------------------------------------------------------- * height height($dst_height, $sharpen_mode=null) param: $dst_height - (integer) param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you prioritize the height, like with pageimage. Additionally, after resizing, an automatic sharpening can be done with one of the three modes. ------------------------------------------------------------------- * resize resize($dst_width=0, $dst_height=0, $sharpen_mode=null) param: $dst_width - (integer) default is 0 param: $dst_height - (integer) default is 0 param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you have to set width and / or height, like with pageimage size().

That way you can get better result of sharpened images. ------------------------------------------------------------------- * sharpen sharpen($mode='soft') param: $mode - (string) possible values 'none' | 'soft'| 'medium'| 'strong' return: pim - (class handle) Applys sharpening to the current memory image. You can call it with one of the three predefined pattern, or you can pass an array with your own pattern. ------------------------------------------------------------------- * unsharpMask unsharpMask($amount, $radius, $threshold) param: $amount - (integer) 0 - 500, default is 100 param: $radius - (float) 0.1 - 50, default is 0.5 param: $threshold - (integer) 0 - 255, default is 3 return: pim - (class handle) Applys sharpening to the current memory image like the equal named filter in photoshop.

You can define how strong it should be applied, 1 is low and 255 is strong. ------------------------------------------------------------------- * blur blur() return: pim - (class handle) Blur is like smooth, but cannot called with a value. It seems to be similar like a result of smooth with a value greater than 200. ------------------------------------------------------------------- * crop crop($pos_x, $pos_y, $width, $height) param: $pos_x - (integer) start position left param: $pos_y - (integer) start position top param: $width - (integer) horizontal length of desired image part param: $height - (integer) vertical length of desired image part return: pim - (class handle) This method cut out a part of the memory image. ------------------------------------------------------------------- * canvas canvas($width, $height, $bgcolor, $position, $padding) param: $width = mixed, associative array with options or integer, - mandatory! param: $height = integer, - mandatory if $width is integer! param: $bgcolor = array with rgb or rgba, - default is array(255, 255, 255, 0) param: $position = one out of north, northwest, center, etc, - default is center param: $padding = integer as percent of canvas length, - default is 0 return: pim - (class handle) This method creates a canvas according to the given width and height and position the memory image onto it. You can pass an associative options array as the first and only param. With it you have to set width and height and optionally any other valid param. Or you have to set at least width and height as integers. Hint: If you want use transparency with rgba and your sourceImage isn't of type PNG, you have to define 'png' as outputFormat with your initially options array or, for example, like this: $image->pimLoad('prefix')->setOutputFormat('png')->canvas(300, 300, array(210,233,238,0.5), 'c', 5)->pimSave() ------------------------------------------------------------------- * flip flip($vertical=false) param: $vertical - (boolean) default is false return: pim - (class handle) This flips the image horizontal by default. (mirroring) If the boolean param is set to true, it flips the image vertical instead. ------------------------------------------------------------------- * rotate rotate($degree, $backgroundColor=127) param: $degree - (integer) valid is -360 0 360 param: $backgroundColor - (integer) valid is 0 - 255, default is 127 return: pim - (class handle) This rotates the image. Positive values for degree rotates clockwise, negative values counter clockwise. If you use other values than 90, 180, 270, the additional space gets filled with the defined background color. ------------------------------------------------------------------- * brightness brightness($level) param: $level - (integer) -255 0 255 return: pim - (class handle) You can adjust brightness by defining a value between -255 and +255. Zero lets it unchanged, negative values results in darker images and positive values in lighter images. ------------------------------------------------------------------- * contrast contrast($level) param: $level - (integer) -255 0 255 return: pim - (class handle) You can adjust contrast by defining a value between -255 and +255. Zero lets it unchanged, negative values results in lesser contrast and positive values in higher contrast. ------------------------------------------------------------------- * grayscale grayscale() return: pim - (class handle) Turns an image into grayscale. Remove all colors. ------------------------------------------------------------------- * sepia sepia() return: pim - (class handle) Turns the memory image into a colorized grayscale image with a predefined rgb-color that is known as "sepia". ------------------------------------------------------------------- * colorize colorize($anyColor) param: $anyColor - (array) like css rgb or css rgba - but with values for rgb -255 - +255, - value for alpha is float 0 - 1, 0 = transparent 1 = opaque return: pim - (class handle) Here you can adjust each of the RGB colors and optionally the alpha channel. Zero lets the channel unchanged whereas negative values results in lesser / darker parts of that channel and higher values in stronger saturisation of that channel. ------------------------------------------------------------------- * negate negate() return: pim - (class handle) Turns an image into a "negative". ------------------------------------------------------------------- * pixelate pixelate($blockSize=3) param: $blockSize - (integer) 1 - ??, default is 3 return: pim - (class handle) This apply the well known PixelLook to the memory image. It is stronger with higher values for blockSize. ------------------------------------------------------------------- * emboss emboss() return: pim - (class handle) This apply the emboss effect to the memory image. ------------------------------------------------------------------- * edgedetect edgedetect() return: pim - (class handle) This apply the edge-detect effect to the memory image. ------------------------------------------------------------------- * getMemoryImage getMemoryImage() return: memoryimage - (GD-Resource) If you want apply something that isn't available with that class, you simply can check out the current memory image and apply your image - voodoo - stuff ------------------------------------------------------------------- * setMemoryImage setMemoryImage($memoryImage) param: $memoryImage - (GD-Resource) return: pim - (class handle) If you are ready with your own image stuff, you can check in the memory image for further use with the class. ------------------------------------------------------------------- * watermarkLogo watermarkLogo($pngAlphaImage, $position='center', $padding=2) param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW, - or: north, east, south, west, center, northeast, southeast, southwest, northwest default is 'center' param: $padding - (integer) 0 - 25, default is 5, padding to the borders in percent of the images length! return: pim - (class handle) You can pass a transparent image with its filename or as a PageImage to the method. If the watermark is bigger than the destination-image, it gets shrinked to fit into the targetimage. If it is a small watermark image you can define the position of it: NW - N - NE | | | W - C - E | | | SW - S - SE The easiest and best way I have discovered to apply a big transparency watermark to an image is as follows: create a square transparent png image of e.g. 2000 x 2000 px, place your mark into the center with enough (percent) of space to the borders. You can see an example here! The $pngAlphaImage get centered and shrinked to fit into the memory image. No hassle with what width and / or height should I use?, how many space for the borders?, etc. ------------------------------------------------------------------- * watermarkLogoTiled watermarkLogoTiled($pngAlphaImage) param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency return: pim - (class handle) Here you have to pass a tile png with transparency (e.g. something between 150-300 px?) to your bigger images. It got repeated all over the memory image starting at the top left corner. ------------------------------------------------------------------- * watermarkText watermarkText($text, $size=10, $position='center', $padding=2, $opacity=50, $trueTypeFont=null) param: $text - (string) the text that you want to display on the image param: $size - (integer) 1 - 100, unit = points, good value seems to be around 10 to 15 param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW, - or: north, east, south, west, center, northeast, southeast, southwest, northwest default is 'center' param: $padding - (integer) 0 - 25, default is 2, padding to the borders in percent of the images length! param: $opacity- (integer) 1 - 100, default is 50 param: $trueTypeFont - (string) systemfilepath to a TrueTypeFont, default is freesansbold.ttf (is GPL & comes with the module) return: pim - (class handle) Here you can display (dynamic) text with transparency over the memory image. You have to define your text, and optionally size, position, padding, opacity for it. And if you don't like the default font, freesansbold, you have to point to a TrueTypeFont-File of your choice.

Hi, After the move to ProcessWire on one of our major websites, I had to build myself a module/plugin so I could use the Amazon S3 / CloudFront infrastructure. The module/plugin uses Amazon S3 PHP SDK and the idea was to provide a clean way to upload/backup files to S3 and distribute the assets via Cloudfront. The current version of the module/plugin will copy the page files to Amazon S3 so you can then serve the via Cloudfront automatically. Note that the files are still also copied to the server where your PW installation resides. There's an option to backup the deleted files to another folder on S3 because when you delete a file on PW via the admin, the file is also deleted from it's folder on S3. The module also supports Apeisa's Thumbnail module so it also stores the thumbnails on S3. Note that the native size() method to create image thumbnails on S3 is currently not supported. As it is, the module will only upload new assets, so beware that if you already have pages created with assets you'll definitely have errors, so my advice is to test this with a blank installation of PW. If anyone wants to test it and contribute to it, I think this provides a good proof of concept for a functionality that is requested by several users (me included). Please note that I'm not a PHP developer, my skills (very) limited and I'm aware that it can be improved and I'm open to suggestions, feedback and most of all, collaborators. The module is hosted on github here and it's available in the ProcessWire modules directory. Nelson Mendes1 point

Hey Friends of Webanalytics, I've finished the main work on porting Wanzes GA into a PiwikAnalytics Module. Just uploaded it to the modules directory. It does pretty much the same like GAModule So take a look at the module post: http://processwire.com/talk/topic/1609-processgoogleanalytics/ You could download the module in the directory or directly from my site: http://misterui.de/site/assets/files/1087/piwikanalytics.zip Cheerio1 point

Hi I would like to share with you my first module. Module integrates PixlrEditor with a InputfieldImage. You can easily edit your images online. The module provides a link to edit each field type InputfieldImage. Have fun;) Warning: I have not tested yet on localhost. As Ryan pointed out. It does not work on localhost. Pixlr webservice must have the ability to get images from your server. Source: https://github.com/P...GIX/PixlrEditor Screenshots: Changelog 1.0.2Now Support Thumbnails Module - Thanks to joey102030 for the addition.1 point

Hi! As apeisa mentioned, this is very simple to build. Unless you need preloading, transitions etc, something like this should cover your needs. <img id="big" src="image1.jpg"> <div id="thumbnails"> <a href="image1.jpg"><img src="image1_thumb.jpg"></a> <a href="image2.jpg"><img src="image2_thumb.jpg"></a> <a href="image3.jpg"><img src="image3_thumb.jpg"></a> </div> And jQuery... $("#thumbnails a").on('click', function(e) { e.preventDefault(); $('#big').attr('src', $(this).attr('href')); });1 point

Hello community, i´m proud to tell you that my first website with processwire is online Even though I have not necessarily chosen the easiest project for me ... it was/is a great joy to work with processwire and I´m very glad to have discovered this great system and this very helpful community, thanks that I could be a part of it! Now to the page: It is a Trakehner horse breeding farm in southern Germany. www.trakehnerhof-st-vitus.de The basic system is based on the site template by Martijn (here again many THANKS Martijn). It is supplemented by a responsive Design with bootstrap, meanmenu, nivo-slider, magnific-popup and some css stuff. To import more than 500 individual horse sites, the CSV import module helped me a lot. By some Excel magic in the run-up and then a clean csv file the import to processwire was very easy! Installed Modules: - Image cropping tool - Get Video Thumbnails - ProcessImageMinimize - Piwik Analytics - MinifyHTML just to name a few ... So what do you say? Would you buy a horse1 point

Very useful piece of code indeed, thank you! It kind of goes haywire if $itemsInColumn is uneven though. Using ceil($num / $columns); instead of intval($num / $columns); fixed it for me! cheers phil1 point

I can confirm there is something strange happening with 2.4.5 and admin theme switching. It may have existed before that as well. Happens on both Mac/PC and is not specifically related to Modesta. I submitted an issue on github1 point

It was just the setting for the image. Thank you. It's works when I add this code to the template file but will not work if I use Hanna Code. I cannot get hanna code to output php from body content. I do have it set in body setting but still wont work.1 point

Depends what field "image" is really. If it's single image field your code would be fine. If it allows more than 1 image it will be a WireArray, and your code would fail. Then you'd need to treat it as such using if($product->image->count){ ... } Then you'd access images in the array using a foreach loop, or with one of the array functions $product->image->first()->url or $product->image->eq(n)->url If that's the case you might want to set "image" to allow only 1 image (as the name suggests) ,then your code would work and be consistent with the naming. After all I could have also linked to the other 1'000'000 threads about this very same image field problem everybody has. But maybe it's just enough to link to the documentation which explains this again. https://processwire.com/api/fieldtypes/images/1 point

You might want to have a look at this alpha module from Soma: https://github.com/somatonic/BlocksContent There is some discussion about it here: https://processwire.com/talk/topic/4189-flexibility-in-page-design/?p=45437 You might want to browse further back in that thread too. One other possibility might be the new PageTable field type which allows for adding multiple content blocks (you can define multiple templates) that can be sorted by the user, so you could easily have a separate Add button for each of your content types - I think this could be pretty effective actually. There isn't any real documentation for PageTable yet, but you can start reading here: https://processwire.com/talk/topic/6417-processwire-profields-table/page-2#entry628901 point

Ryans fix in latest dev works! ...and I just want to say how thankful I am that Ryan is such a responsive developer. One more thing: I did some speed benchmarks on 2.4.5 and can say that 2.4.5 is approximately 30% faster compared to 2.4.4 on my projects. Awesome!1 point

NooseLadder - the link to the module the horst provided is designed primary to migrate page content and as a result it also grabs changes to fields and templates that are used by these pages. You can use the "Changes Since" option during export to grab all the changes to your site since that date/time and things should work as expected. The one thing thing that might seem confusing is that if you only make changes to template or field settings, you still need to export a page/pages that contain these templates/fields to capture these changes. Mindplay's work in progress module might also be useful here: https://processwire.com/talk/topic/2117-continuous-integration-of-field-and-template-changes/ although his is only about field/template changes. Personally I can see using both options depending on the needs. I still don't consider Migrator release worthy, so you should definitely test the import to a test PW installation before trying it on your live site. I do hope to get it finalized sometime in the next few weeks or so..... There are some small outstanding issues (like template context field settings) and also I need to test support for all the new pro fields which I haven't done yet. One thing I really need is help testing it1 point

PageImage Manipulator - Tips & Examples * how to create a PNG with transparency for the watermarkLogo method If you can use adobe photoshop, you simply may download and install this action: photoshop_action_PW-png-creations.zip create an empty image (transparent, not white or black) of 2000 x 2000 pixel write / paste your text and / or logo in a single color, (e.g. black) when finished with your text you should have one single layer with text on transparent background then click the action PW-png-creations -> 2000px-square-to-smooth and you are done. Hhm, maybe before saving you want to tweak the global transparency of the image a bit. That one used in the ProcessWire example was set to 75% instead of 100%. Just try out what looks best for you. ------------------------------------------------------------------- * did you know that you can save to different file formats, regardless of source format? You only have to specify your desired format (gif, jpg, png) with the optionally options array with a key named outputFormat and pass it with your call to pimLoad() or use setOptions() before any other action-method: // assuming the first image is a jpeg $img = $page->images->first(); // define outputFormat $options = array('outputFormat'=>'png'); // apply it together with other actions $myPng = $img->pimLoad('myPrefix')->setOptions($options)->width(240)->pimSave(); //------------------------------------------------------------------------------------------ // you may also do it as a OneLiner only with the image format conversion $myPng = $page->images->eq(0)->pimLoad('myPrefix', array('outputFormat'=>'png'))->pimSave(); // or you can use the setOutputFormat method $myPng = $page->images->first()->pimLoad('myPrefix')->setOutputFormat('png')->pimSave(); ------------------------------------------------------------------- * (how) can I use the ImageManipulator with other imagefiles than PW-Pageimages? You can load any imagefile from your servers filesystem into the ImageManipulator with: $pim = wire('modules')->get('PageImageManipulator')->imLoad($imageFilename); // or $pim = $wire->modules->get('PageImageManipulator')->imLoad($imageFilename, $options); You can directly with the imLoad-method pass specific $options or you can do a separate call to setOptions(). Then you do your desired actions and last but not least you call save()! Most time I think the original passed file gets overwritten with the manipulation result, but you are also able to save to a different name and / or fileformat. If so, it is useful to get the final (sanitized) filename back after saveing. $optionalNewFilename = $pim->setOptions($options)->height(360)->flip()->blur()->save(); Also you may call this in one line if you prefer: if(false!==$wire->modules->get('PageImageManipulator')->imLoad($imageFilename,$options)->height(360)->flip()->blur()->save()) { // success !! } ------------------------------------------------------------------- * how can I use the PageImageManipulator with my own module/s? If you build a module that do some image manipulation you can define the PIM as needed dependency in your ModulesInfo method with the key 'requires'. You may also force to install the PIM if it isn't already with the key 'installs': public static function getModuleInfo() { return array( // ... 'requires' => array('PageImageManipulator'), 'installs' => 'PageImageManipulator', // ... ); } detailed infos are here: http://processwire.com/talk/topic/778-module-dependencies/ additionally, if you need to check if a module dependency has a minimum version number, you can do it in your install method like this: public function ___install() { // check that at least the minimum version number is installed $needed = '0.0.3'; $a = wire('modules')->get('PageImageManipulator')->getModuleInfo(); $actual = preg_replace('/(\d)(?=\d)/', '$1.', str_pad("{$a['version']}", 3, "0", STR_PAD_LEFT)); if(version_compare($actual, $needed, '<')) { throw new WireException(sprintf($this->_(__CLASS__ . " requires PageImageManipulator %s or newer. Please update."), $needed)); return; } // ... more code } ------------------------------------------------------------------- * global options in site/config.php You can create a config-array in your site/config.php. If you look into it you will find a config array for the ImageSizer that comes with the PW core $config->imageSizerOptions = array( 'autoRotation' => true, 'sharpening' => 'soft', 'upscaling' => true, 'cropping' => true, 'quality' => 90 ); You can define another array with these keys: $config->imageManipulatorOptions = array( 'autoRotation' => true, 'sharpening' => 'soft', 'upscaling' => false, 'cropping' => true, 'quality' => 90, 'bgcolor' => array(255,255,255,0), ); You don't have to specify all of the options. PiM reads the imageSizerOptions and merge them with the imageManipulatorOptions. So if you want to have different values you can specify them in imageManipulatorOptions to override those from imageSizerOptions. Only one option isn't present with the imageSizer: bgcolor. This is only used by the imageManipulator. ------------------------------------------------------------------- * using PiM together with the awesome Thumbnails Module (http://mods.pw/1b) If you use the Thumbnails Module together with PiM, you can set two options in the site/config.php under imageManipulatorOptions: $config->imageManipulatorOptions = array( // ... 'thumbnailColorizeCustom' => array(40,-35,0), 'thumbnailCoordsPermanent' => true ); For the colorize dropdown select you can define the custom color here and with the second param you enable/disable permanent storage of RectangleCoords and params. The coords and params are stored with Thumbnails Module per session, but are lost after the session is closed. If you enable permanent storage these data is written into a custom IPTC field of the original imagefile. ------------------------------------------------------------------- * some more examples will folow here . . . -------------------------------------------------------------------1 point

I recently had to setup front-end system to handle logins, password resets and changing passwords, so here's about how it was done. This should be functional code, but consider it pseudocode as you may need to make minor adjustments here and there. Please let me know if anything that doesn't compile and I'll correct it here. The template approach used here is the one I most often use, which is that the templates may generate output, but not echo it. Instead, they stuff any generated output into a variable ($page->body in this case). Then the main.php template is included at the end, and it handles sending the output. This 'main' template approach is preferable to separate head/foot includes when dealing with login stuff, because we can start sessions and do redirects before any output is actually sent. For a simple example of a main template, see the end of this post. 1. In Admin > Setup > Fields, create a new text field called 'tmp_pass' and add it to the 'user' template. This will enable us to keep track of a temporary, randomly generated password for the user, when they request a password reset. 2a. Create a new template file called reset-pass.php that has the following: /site/templates/reset-pass.php $showForm = true; $email = $sanitizer->email($input->post->email); if($email) { $u = $users->get("email=$email"); if($u->id) { // generate a random, temporary password $pass = ''; $chars = 'abcdefghjkmnopqrstuvwxyz23456789'; // add more as you see fit $length = mt_rand(9,12); // password between 9 and 12 characters for($n = 0; $n < $length; $n++) $pass .= $chars[mt_rand(0, strlen($chars)-1)]; $u->of(false); $u->tmp_pass = $pass; // populate a temporary pass to their profile $u->save(); $u->of(true); $message = "Your temporary password on our web site is: $pass\n"; $message .= "Please change it after you login."; mail($u->email, "Password reset", $message, "From: noreply@{$config->httpHost}"); $page->body = "<p>An email has been dispatched to you with further instructions.</p>"; $showForm = false; } else { $page->body = "<p>Sorry, account doesn't exist or doesn't have an email.</p>"; } } if($showForm) $page->body .= " <h2>Reset your password</h2> <form action='./' method='post'> <label>E-Mail <input type='email' name='email'></label> <input type='submit'> </form> "; // include the main HTML/markup template that outputs at least $page->body in an HTML document include('./main.php'); 2b. Create a page called /reset-pass/ that uses the above template. 3a. Create a login.php template. This is identical to other examples you may have seen, but with one major difference: it supports our password reset capability, where the user may login with a temporary password, when present. When successfully logging in with tmp_pass, the real password is changed to tmp_pass. Upon any successful authentication tmp_pass is cleared out for security. /site/templates/login.php if($user->isLoggedin()) $session->redirect('/profile/'); if($input->post->username && $input->post->pass) { $username = $sanitizer->username($input->post->username); $pass = $input->post->pass; $u = $users->get($username); if($u->id && $u->tmp_pass && $u->tmp_pass === $pass) { // user logging in with tmp_pass, so change it to be their real pass $u->of(false); $u->pass = $u->tmp_pass; $u->save(); $u->of(true); } $u = $session->login($username, $pass); if($u) { // user is logged in, get rid of tmp_pass $u->of(false); $u->tmp_pass = ''; $u->save(); // now redirect to the profile edit page $session->redirect('/profile/'); } } // present the login form $headline = $input->post->username ? "Login failed" : "Please login"; $page->body = " <h2>$headline</h2> <form action='./' method='post'> <p> <label>Username <input type='text' name='username'></label> <label>Password <input type='password' name='pass'></label> </p> <input type='submit'> </form> <p><a href='/reset-pass/'>Forgot your password?</a></p> "; include("./main.php"); // main markup template 3b. Create a /login/ page that uses the above template. 4a. Build a profile editing template that at least lets them change their password (but take it further if you want): /site/templates/profile.php // if user isn't logged in, then we pretend this page doesn't exist if(!$user->isLoggedin()) throw new Wire404Exception(); // check if they submitted a password change $pass = $input->post->pass; if($pass) { if(strlen($pass) < 6) { $page->body .= "<p>New password must be 6+ characters</p>"; } else if($pass !== $input->post->pass_confirm) { $page->body .= "<p>Passwords do not match</p>"; } else { $user->of(false); $user->pass = $pass; $user->save(); $user->of(true); $page->body .= "<p>Your password has been changed.</p>"; } } // display a password change form $page->body .= " <h2>Change password</h2> <form action='./' method='post'> <p> <label>New Password <input type='password' name='pass'></label><br> <label>New Password (confirm) <input type='password' name='pass_confirm'></label> </p> <input type='submit'> </form> <p><a href='/logout/'>Logout</a></p> "; include("./main.php"); 4b. Create a page called /profile/ that uses the template above. 5. Just to be complete, make a logout.php template and create a page called /logout/ that uses it. /site/templates/logout.php if($user->isLoggedin()) $session->logout(); $session->redirect('/'); 6. The above templates include main.php at the end. This should just be an HTML document that outputs your site's markup, like a separate head.inc or foot.inc would do, except that it's all in one file and called after the output is generated, and we leave the job of sending the output to main.php. An example of the simplest possible main.php would be: /site/templates/main.php <html> <head> <title><?=$page->title?></title> </head> <body> <?=$page->body?> </body> </html>1 point

Ryan, Thanks this gave me a great place to start. I thought I'd share the version I created in case anyone finds it useful. • Single template for the login/logout. • Automatically redirects the user back to whatever page they originally requested after they login. ./includes/login.php <?php // Handle logouts if($input->get->logout == 1) { $session->logout(); $session->redirect($page->path); } // If they aren't logged in, then show the login form if(!$user->isLoggedin()){ // check for login before outputting markup if($input->post->user && $input->post->pass) { $user = $sanitizer->username($input->post->user); $pass = $input->post->pass; if($session->login($user, $pass)) { // login successful $session->redirect($page->path); } else { $session->login_error = 'Login Failed. Please try again, or use the forgot password link below.'; } } ?> <!DOCTYPE HTML> <html lang="en"> <head> <title>Custom PW Login</title> </head> <body> <form action='./' method='post'> <div class="login"> <? if($input->post->user && $input->post->pass) { echo "<p class='error'>" . $session->login_error . "</p>"; }?> <p><input type='text' id="user" name='user' placeholder='Username'/></p> <p><input type='password' id="pass" name='pass' placeholder="Password" /></p> <p><input type='submit' class="btn" name='submit' value='Login' /></p> </div> </form> </body> </html> <? die(); // don't go any further if not logged in } // end !logged in ?> In any template you wish to protect: <? require("./includes/login.php");?> To trigger a logout: <a href="?logout=1">Logout</a> Note: I'm using the HTML5 placeholder attribute. Browser support is not 100%. You may want to use labels instead, or use some jQuery (like I did) to add the placeholder text for browser that don't support it. SideNote: How do you get code indents to stick when posting? I'm having to go back and add spaces to each line. I use tabs when coding.1 point
