Unless I want to save the value of a page object's property in the database, I would not change a page object's property because it is reasonable to expect that a property corresponds to a value in the database. If I change the property but do not save it to the database, then from that point on it is "confusing" to keep track of the actual value of the property as its value is no longer "in sync" with the database (as long as we are talking about the same request being executed, of course). To tell the truth, I do not really get what you are trying to solve. I was just trying to point out a few things that might – but not necessarily – cause issues.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: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you have to set width and / or height, like with pageimage size(). Additionally, after resizing, an automatic sharpening can be done with one of the three modes. ------------------------------------------------------------------- * stepResize stepResize($dst_width=0, $dst_height=0) param: $dst_width - (integer) default is 0 param: $dst_height - (integer) default is 0 return: pim - (class handle) this performs a resizing but with multiple little steps, each step followed by a soft sharpening. That way you can get better result of sharpened images. ------------------------------------------------------------------- * sharpen sharpen($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: $threshold - (integer) 0 - 255, default is 3 return: pim - (class handle) Applys sharpening to the current memory image like the equal named filter in photoshop. Credit for the used unsharp mask algorithm goes to Torstein Hønsi who has created the function back in 2003. ------------------------------------------------------------------- * smooth smooth($level=127) param: $level - (integer) 1 - 255, default is 127 return: pim - (class handle) Smooth is the opposite of sharpen. You can define how strong it should be applied, 1 is low and 255 is strong. ------------------------------------------------------------------- * blur blur() return: pim - (class handle) Blur is like smooth, but cannot called with a value. It seems to be similar like a result of smooth with a value greater than 200. ------------------------------------------------------------------- * crop crop($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.

This week a second new module for processing Stripe payments has been added to FormBuilder. Unlike our other Stripe Inputfield for FormBuilder, this new one uses Stripe Checkout and supports 3D Secure (SCA) payments. We’ll take a closer look at it in this blog post, plus we’ve got a live demo of it here too— https://processwire.com/blog/posts/stripe-payment-processor-form-builder/1 point

What does this mean exactly? No save? No post? ? Depends on the type of field. Plain text? Not repeaters by the looks of it. Maybe a little bit more info will help get better responses :-).1 point

First things I'd do: check PW logs check server error logs (Apache / PHP) inspect in the browser (JS errors) If you don't find any hints that way, you could see if it's a CSRF problem, or something to do with sessions. Switching to SessionHandlerDB can help (a core module). In one of my setups I had to put these two config values to false, when I encountered similar problems: $config->protectCSRF = false; $config->sessionFingerprint = false;1 point

Hey @bernhard! Thanks for reporting this. The latter problem is connected to the first one. Config screen asks the main module for the paths object, but due to a recent change this wasn't available. This is fixed now in the latest version of the module (0.17.1).1 point

Hi @teppo any ideas why I'm getting this error on a fresh install? Notice: Trying to get property 'paths' of non-object in C:\laragon\www\micropage\site\modules\Wireframe\lib\Config.php on line 163 Warning: Creating default object from empty value in C:\laragon\www\micropage\site\modules\Wireframe\lib\Config.php on line 173 Also the directories look weird. The regular directories have not been created, but they are also not listed on the settings page:1 point

Maybe a sign that it's times for a break ?. Sometimes it helps to 'speak out your code' to determine if it makes sense. Have a look at that line. tableofcontents_table, I assume, is your Profields Table. Reading that out loud, your code is saying, find me siblings (PLURAL) of this page and get me the value of its (SINGLE) tableofcontents_table field. Doesn't sound right, does it? It's like saying 'find me 10 oranges (PLURAL) and show me its (SINGLE) price. That's wrong. The question would be, which orange's price? We have 10 oranges here! It should read, 'find me 10 oranges (PLURAL) and show me their (PLURAL) prices. Aha, so, we are dealing with a collection. Any collection has to be iterated (foreach) to get each members individual value. Alternatively, you could ask for the first(), last() or nth() orange to deal with one member only. OK, so I need to get some sleep too. The docs say this about $page->siblings(): $toc is a PageArray. If you run this in Tracy console: <?php d($page->siblings("template=tableofcontents")->tableofcontents_table);// null You will get the value null, hence your error message since you are doing this null->render(). Now for some unsolicited advice ?. TracyDebugger is your best friend. The table clearly is there and clearly is a sibling and its template is as stated and the table also. Whilst this might be the case, it is best to always check if your selector/query returned something (and its type) before you start working with it. Hope this helps. ps: Profields Table has its own VIP support forum, accessible to you if you have a current subscription1 point

I figured it out! Sub-selectors was the wrong approach, but a subfield selector seems to do the trick: $articles = page()->children('sort=authors.lastname'); Woo. Love it!1 point

Yeah, we all struggle with that sometimes. ? I did a bit of experimenting and here's another way the language options can be removed from the title field: // Single-language title field for "test-template" at Page Add $wire->addHookAfter('ProcessPageAdd::getAllowedTemplates', function(HookEvent $event) { $tpls = $event->return; $t = $event->wire()->templates->get('test-template'); if(isset($tpls[$t->id])) $tpls[$t->id]->noLang = 1; $event->return = $tpls; }); // Single-language title field for "test-template" at Page Edit $wire->addHookAfter('ProcessPageEdit::buildFormContent', function(HookEvent $event) { /** @var InputfieldForm $form */ $form = $event->return; $page = $event->object->getPage(); if($page->template == 'test-template') { $title = $form->getChildByName('title'); if($title) $title->useLanguages = false; } });1 point
