  1. Hi, on a site I want to disable access to original images and only allow to access thumbnails and watermarked image variations. EDIT: A good solution for protecting original images can be found a bit down in this thread: Old content of this initial post:
  2. Select Images An inputfield that allows the visual selection and sorting of images, intended for use with the FieldtypeDynamicOptions module. Together these modules can be used to create a kind of "image reference" field. Integration with FieldtypeDynamicOptions InputfieldSelectImages was developed to be used together with FieldtypeDynamicOptions (v0.1.3 or newer): Create a Dynamic Options field. Choose "Select Images" as the "Inputfield type". Select Images appears in the "Multiple item selection" category but you can set "Maximum number of items" to 1 if you want to use Select Images for single image selections. Define selectable options for the field via a FieldtypeDynamicOptions::getSelectableOptions hook. See some examples below. FieldtypeDynamicOptions is recommended but is not a strict requirement for installing InputfieldSelectImages in case you want to use an alternative way to store the field data. Selection of Pageimages In this example the field allows selection of Pageimages that are in the "images" field of the home page. The field will store URLs to the Pageimages so it works as a kind of "image reference" field. You can use the "Format as Pagefile/Pageimage object(s)" option for the Dynamic Options field to have the formatted value of the field be automatically converted from the stored Pageimage URLs to Pageimage objects. $wire->addHookAfter('FieldtypeDynamicOptions::getSelectableOptions', function(HookEvent $event) { // The page being edited $page = $event->arguments(0); // The Dynamic Options field $field = $event->arguments(1); // For a field named "select_images" if($field->name === 'select_images') { $options = []; // Get Pageimages within the "images" field on the home page foreach($event->wire()->pages(1)->images as $image) { // Add an option for each Pageimage // When the key is a Pageimage URL the inputfield will automatically create a thumbnail // In this example the label includes the basename and the filesize /** @var Pageimage $image */ $options[$image->url] = "{$image->basename}<br>{$image->filesizeStr}"; } $event->return = $options; } }); Selection of image files not associated with a Page When not working with Pageimages you must add a "data-thumb" attribute for each selectable option which contains a URL to a thumbnail/image. In this example the field allows selection of image files in a "/pics/" folder which is in the site root. $wire->addHookAfter('FieldtypeDynamicOptions::getSelectableOptions', function(HookEvent $event) { // The page being edited $page = $event->arguments(0); // The Dynamic Options field $field = $event->arguments(1); // For a field named "select_images" if($field->name === 'select_images') { $options = []; // Get files that are in the /pics/ folder $root = $event->wire()->config->paths->root; $path = $root . 'pics/'; $files = $event->wire()->files->find($path); // Add an option for each file foreach($files as $file) { $basename = str_replace($path, '', $file); $url = str_replace($root, '/', $file); // The value must be an array with the following structure... $options[$url] = [ // The label for the image 'label' => $basename, 'attributes' => [ // An image URL in the "data-thumb" attribute 'data-thumb' => $url, ], ]; } $event->return = $options; } }); The field values don't have to be image URLs The values stored by the Dynamic Options field don't have to be image URLs. For example, you could use the images to represent different layout options for a page, or to represent widgets that will be inserted on the page. Also, you can use external URLs for the thumbnails. In the example below the options "calm" and "crazy" are represented by thumbnails from placecage.com. $wire->addHookAfter('FieldtypeDynamicOptions::getSelectableOptions', function(HookEvent $event) { // The page being edited $page = $event->arguments(0); // The Dynamic Options field $field = $event->arguments(1); // For a field named "calm_or_crazy" if($field->name === 'calm_or_crazy') { $options = []; // Add options that are illustrated with thumbnails from placecage.com $options['calm'] = [ // The label for the option 'label' => 'Nicolas Cage is a calm man', 'attributes' => [ // An image URL in the "data-thumb" attribute 'data-thumb' => 'https://www.placecage.com/260/260', ] ]; $options['crazy'] = [ // The label for the option 'label' => 'Nicolas Cage is a crazy man', 'attributes' => [ // An image URL in the "data-thumb" attribute 'data-thumb' => 'https://www.placecage.com/c/260/260', ] ]; $event->return = $options; } }); Field configuration You can define labels for the button, notices, etc, that are used within the inputfield if the defaults don't suit. https://github.com/Toutouwai/InputfieldSelectImages https://processwire.com/modules/inputfield-select-images/
  3. Hey, so we all know about SEO and the importance of performance. Basically we do it, because if no one finds the website we just built, it´s frustrating. We all try to write clean markup, css and js code and most might have a webpack/gulp/whatever pipeline to minimize css&js. But when thinking about it, optimizing your pipeline might save you a few (hundreds) of kb, compared to loading an image with 1 mb that´s literally nothing and frankly just ridiculous. Don´t get me wrong, frontend pipelines are great and should be used, but let´s shift your "I will optimize the shit out of that 3 css lines" focus to something different: try to serve images as fast as possible, this is where the performance boost really happens. I´m no pro on processwire so far, but I built a very easy to use picture element, which some of you could find interesting: 1. the picture comes with 3 different sizes: one for mobile (keep in mind the double dpi, therefore width of 828px), one for tablet and one for desktop 2. the picture generates a webp version and the original file extension as a fallback 3. the filesize of each element is rendered within the "data" attribute 4. lazy loading(sooo important!!!) is done via the native 'loading="lazy"' attribute. Please try it out and see the difference 🙂 I posted this so others can easily optimize their images, but I would also like to hear your suggestions in making it better. Maybe you could decrease the rendering time or maybe you have some easy improvements. Please let me know. Greetings from Austria! <picture> <source data="<?php echo($oElement->repeater_image->width(828)->webp->filesize);?>" media="(max-width: 414px)" srcset="<?php echo($oElement->repeater_image->width(828)->webp->url) ?> 2x" type="image/webp"> <source data="<?php echo($oElement->repeater_image->width(828)->filesize) ?>" media="(max-width: 414px)" srcset="<?php echo($oElement->repeater_image->width(828)->url) ?> 2x" type="image/<?php echo($oElement->repeater_image->ext)?>"> <source data="<?php echo($oElement->repeater_image->width(767)->webp->filesize) ?>" media="(min-width: 415) and (max-width: 767px)" srcset="<?php echo($oElement->repeater_image->width(767)->webp->url) ?> 2x" type="image/webp"> <source data="<?php echo($oElement->repeater_image->width(767)->filesize) ?>" media="(min-width: 415) and (max-width: 767px)" srcset="<?php echo($oElement->repeater_image->width(767)->url) ?> 2x" type="image/<?php echo($oElement->repeater_image->ext)?>"> <source data="<?php echo($oElement->repeater_image->webp->filesize) ?>" media="(min-width: 768px)" srcset="<?php echo($oElement->repeater_image->webp->url) ?>" type="image/webp"> <source data="<?php echo($oElement->repeater_image->filesize) ?>" media="(min-width: 768px)" srcset="<?php echo($oElement->repeater_image->url) ?>" type="image/<?php echo($oElement->repeater_image->ext)?>"> <img data="<?php echo($oElement->repeater_image->filesize) ?>" class="img-fluid" loading="lazy" src="<?php echo($oElement->repeater_image->url) ?>" alt="<?php echo($oElement->repeater_image->description) ?>" type="image/<?php echo($oElement->repeater_image->ext)?>"> </picture>
  4. Hi there, I created a files field which is already populated with images and videos. this field functions as the data for a slideshow. which works fine. but i need to resize the images, which does not work because the files field doesn't allows the ->size command. Is there any way to seperate the images in the files field in order to resize them? edit: i already tried to create a new pageimage: $image = new Pageimage($page->images, $slide->filename); which results in an error: Aw shucks… Fatal Error: Uncaught TypeError: Pageimage::__construct(): Argument #1 ($pagefiles) must be of type Pagefiles, null given, called in <u>site/templates/basic-page.php</u> on line 19 and defined in <u>wire/core/Pageimage.php</u>:162 Thanks alot! Philipp
  5. Hello all, sharing my new module FieldtypeImageReference. It provides a configurable input field for choosing any type of image from selectable sources. Sources can be: a predefined folder in site/templates/ and/or a page (and optionally its children) and/or the page being edited and/or any page on the site CAUTION: this module is under development and not quite yet in a production-ready state. So please test it carefully. UPDATE: the new version v2.0.0 introduces a breaking change due to renaming the module. If you have an older version already installed, you need to uninstall it and install the latest master version. Module and full description can be found on github https://github.com/gebeer/FieldtypeImageReference Install from URL: https://github.com/gebeer/FieldtypeImageReference/archive/master.zip Read on for features and use cases. Features Images can be loaded from a folder inside site/templates/ or site/assets Images in that folder can be uploaded and deleted from within the inputfield Images can be loaded from other pages defined in the field settings Images can be organized into categories. Child pages of the main 'image source page' serve as categories mages can be loaded from any page on the site From the API side, images can be manipulated like native ProcessWire images (resizing, cropping etc.), even the images from a folder Image thumbnails are loaded into inputfield by ajax on demand Source images on other pages can be edited from within this field. Markup of SVG images can be rendered inline with `echo $image->svgcontent` Image names are fully searchable through the API $pages->find('fieldname.filename=xyz.png'); $pages->find('fieldname.filename%=xy.png'); Accidental image deletion is prevented. When you want to delete an image from one of the pages that hold your site-wide images, the module searches all pages that use that image. If any page contains a reference to the image you are trying to delete, deletion will be prevented. You will get an error message with links to help you edit those pages and remove references there before you can finally delete the image. This field type can be used with marcrura's Settings Factory module to store images on settings pages, which was not possible with other image field types When to use ? If you want to let editors choose an image from a set of images that is being used site-wide. Ideal for images that are being re-used across the site (e.g. icons, but not limited to that). Other than the native ProcessWire images field, the images here are not stored per page. Only references to images that live on other pages or inside a folder are stored. This has several advantages: one central place to organize images when images change, you only have to update them in one place. All references will be updated, too. (Provided the name of the image that has changed stays the same) Installation and setup instructions can be found on github. Here's how the input field looks like in the page editor: If you like to give it a try, I'm happy to hear your comments or suggestions for improvement. Install from URL: https://github.com/gebeer/FieldtypeImageReference/archive/master.zip Eventually this will go in the module directory, too. But it needs some more testing before I submit it. So I'd really appreciate your assistance. Thanks to all who contributed their feedback and suggestions which made this module what it is now.
  6. One of PW 3.010's major novelty was the introduction of Horst's new image resizing engine that uses ImageMagick. Now I understand that ImageMagick can convert images to Webp, the image format that Google says can reduce image size up to 34% compared to JPEG. Mozilla is apparently adding support to Firefox, and even the Safari team is playing with it, so it looks like Webp is soon going to be available in most major browsers. If Horst's module can be extended to add Webp conversion, that would be a great addition to PW's already very powerful image manipulation arsenal. I'm currently using the free ImageEngine Lite to serve Webp images to supporting browsers, and the results are impressive. I routinely get images that are between 25 and 60% smaller compared to JPEG, with the same visual quality. I would love to eliminate the need to rely on a third-party service though.
  7. Hi again, after trying pages2PDF, RockPDF and mpdf I'm not sure which of them I should use. Of course, there is also wirePDF. I merged mpdf with rockPDF, add a footer and a page in Landscape and that works, like in the code-snippet below but be am I on the right way? After that I tried a couple of times rendering an image. Nothing happend, the same with Pages2PDF too. I also copied an Image-URL within processwire and tried further getting an Image within the PDF-Document, but it still display only the red marked placeholder. I simply would like create an PDF on click from some Pages including the Images. Are there special requirements on Debian 10 with Apache and php 7.3 using Processwire 3.0.123.? Is there a guide that I didn't found? Is somebody out there who has a similar issue solved and would you be so kind to explain? $pdf = $modules->get('RockPdf'); $mpdf = $pdf->mpdf; # $mpdf->showImageErrors = true; $pdf->set('SetHeader', 'header text'); $mpdf->AddPage('L'); # $mpdf->Image(urlencode('site/assets/files/1845/image-2.275x200.jpg'), 0, 0, 210, 297, 'jpg', '', true, false); $pdf->set('SetFooter', ' <table width="100%"> <tr> <td width="33%">{DATE j.m.Y}</td> <td width="33%" align="center">{PAGENO}/{nbpg}</td> <td width="33%" style="text-align: right;">whatever</td> </tr> </table>'); $pdf->show(); // generate pdf
  8. Hi guys, I’ve recently set up 2 PW installations for using WebP images (following this explanations, strategy 3). Both servers run on identical system configurations and PW versions (3.0.184). While integrating the WebP functionality was no problem at all, I’m massively confused by the results: one server works as expected, the other one does the sheer opposite. Server 1 (the good one): Images total: 326 WebP bigger than JPG: 41 (on average more than 40 %) WebP smaller than JPG: 285 (on average 30–40 %) Server 2 (the bad one): Images total: 862 WebP bigger than JPG: 773 (on average 30–40 %) WebP smaller than JPG: 89 (on average less than 10 %) As far as I know, the quality of the source JPG has an impact on the WebP: highly compressed JPGs may lead to hardly smaller or even bigger WebPs, while the savings with high quality JPGs tend to be more spectacular. Server 1 seems to confirm this assumption (the JPGs with bigger WebPs here are highly compressed 3rd party images) while server 2 ist acting completely strange. The source JPG’s size is around 1.200 x 800 pixel with a moderate compression rate and file sizes ranging between 100 and 500 kB with an average of 250 kB. The JPG quality on server 1 is about the same (regardless the 41 lousy ones), the only difference is their smaller size of 900 x 600 px with an average file size of 150 kB. So I’d consider the WebP use on server 1 as clearly progressive, while server 2 essentially limits itself to fill up the webspace with bigger images that will never appear on a display. Is there any influence on the WebP conversion I might have missed?
  9. WebP image support is great and works fine. But once created I've issues to get rid of all API generated WebP variations. The backend image field variations "Delete" works and I can remove all variations JPEG plus WebP. Image list is clean but all WebP API variations are still stored in file system (for instance files/12345/84.900x675.webp etc). I can only use ImageSizer with temp 'force' option to request fresh WebP variations or have to delete WebP files from folders. No other way so far. Tested with 2 sites and latest master PW 3.0.165. Is there somewhere a "magic button" or config/setup thing to solve my sticky WebP issue?
  10. Add Image URLs Allows images/files to be added to Image/File fields by pasting URLs. Usage Install the Add Image URLs module. A "Paste URLs" button will be added to all image and file fields. Use the button to show a textarea where URLs may be pasted, one per line. Images/files are added when the page is saved. https://github.com/Toutouwai/AddImageUrls https://modules.processwire.com/modules/add-image-urls/
  11. After enabling WebP support you may notice it can take a long time for ProcessWire to create WebP copies of all images and their variations. For instance, on a site I work on (with over 10k images), it was taking about 1 second per image, ie. more than 3 hours in total.. 🥱 If you are comfortable around the command-line, you can use the cwebp program and this bash script to speed things up drastically. I have built upon this script and got things to work in combination with xargs and find, making it rather powerful for PW's purposes. 1. Save this script as 'convert-webp.sh' (or download the Gist from Github), and follow instructions ######################################################################################################### # # Fast Recursive Images to WebP converter # Customized for ProcessWire CMS/CMF <https://www.processwire.com> # # Author: Eelke Feenstra <dev@eelke.net> # Version: 001 # Based upon: https://github.com/onadrog/bash-webp-converter # # Quick & dirty script to add webp versions to all PNG / JPG / JPEG files inside your PW assets folder # # 1. Set this script to executable: # $ chmod +x convert-webp.sh # # 2. Check if cwebp is installed: # $ cwebp -version # If it is not, install: # $ brew install webp # Or follow instructions https://developers.google.com/speed/webp/download # and change $executable to cwebp's full path # # 3. Run the script directly on a folder: # $ ./convert-webp.sh /path/to/your/folder # ######################################################################################################### # Configuration executable="cwebp" # update this to reflect your installation! quality=90 # change to desired WebP quality ######################################################################################################### converted=0 skipped=0 echo "Entering $1" for file in $1/* do name="${file%.*}" echo "FILE: $file" echo "NAME: $name" # Skip the folder itself.. if [ "$name" = "./." ]; then echo "SKIP: $name" continue; fi if [[ $(file --mime-type -b $name.webp) == image/webp ]]; then echo "FOUND: $name.webp, skipping.." skipped=$((skipped+1)) elif [[ $(file --mime-type -b $file) == image/*g ]]; then echo "NOT FOUND: $name.webp" newfile(){ echo "$file" | sed -r 's/(\.[a-z0-9]*$)/.webp/' } $executable -q $quality "$file" -short -o "$(newfile)" converted=$((converted+1)) fi done echo "Converted $converted, Skipped $skipped" 2. Run to create webp versions of all jpg/jpeg/png images in a given folder (for example the site's homepage) $ ./convert-webp.sh /path/to/processwire/site/assets/files/1 3. And in order to create WebP copies of ALL images inside the /site/assets/files folder, you can run this script. It searches for all directories inside the files directory, and passes these to the convert-webp.sh script using xargs. $ find /path/to/processwire/site/assets/files -maxdepth 2 -type d | xargs -I '{}' ./convert-webp.sh '{}' Tested both on MacOS 12 and Debian
  12. Hi, I'm having problems to insert images on a Ckeditor body field. The images are uploaded to a image field and the page is saved. When I do clic in Ckeditor Image button I get: Failed to init module: ProcessPageEditImageSelect - No page specified The requested process does not exist The process returned no content. I'm using the superuser account. Processwire version: 3.0.79 This is the first time I get an error in Processwire... Thank you.
  13. Hi Everyone, As many of you know, iPhone photos save in .heic unless the user changes the settings in their phone. We have built a web app on top of processwire in which a user can save images from their phone. The issue we are having is that there seems to be an error when uploading and saving. The .heic files won't save and processwire throws an error. The environment is LAMP (Bitnami and all libraries have been installed to support this.) Checking to see if someone has also encountered this here and how they solved it. Thanks.
  14. Process Images A basic, proof-of-concept Textformatter module for ProcessWire. When the Textformatter is applied to a rich text field it uses Simple HTML DOM to find <img> tags in the field value and passes each img node through a hookable TextformatterProcessImages::processImg() method. This is a very simple module that doesn't have any configurable settings and doesn't do anything to the field value unless you hook the TextformatterProcessImages::processImg() method. Hook example When added to /site/ready.php the hook below will replace any Pageimages in a rich text field with a 250px square variation and wrap the <img> tag in a link to the original full-size image. For help with Simple HTML DOM refer to its documentation. $wire->addHookAfter('TextformatterProcessImages::processImg', function(HookEvent $event) { // The Simple HTML DOM node for the <img> tag /** @var \simple_html_dom_node $img */ $img = $event->arguments(0); // The Pageimage in the <img> src, if any (will be null for external images) /** @var Pageimage $pageimage */ $pageimage = $event->arguments(1); // The Page object in case you need it /** @var Page $page */ $page = $event->arguments(2); // The Field object in case you need it /** @var Field $field */ $field = $event->arguments(3); // Only for images that have a src corresponding to a PW Pageimage if($pageimage) { // Set the src to a 250x250 variation $img->src = $pageimage->size(250,250)->url; // Wrap the img in a lightbox link to the original $img->outertext = "<a class='lightboxclass' href='{$pageimage->url}'>{$img->outertext}</a>"; } }); GitHub: https://github.com/Toutouwai/TextformatterProcessImages Modules directory: https://processwire.com/modules/textformatter-process-images/
  15. These issues should be fairly easy for any intermediate to advanced ProcessWire developer to answer. I'm new to PHP and relatively new to ProcessWire and just need a bit of help. What I'm trying to do is bring in a couple of cards from my Projects page to display on my home page. I finally got the code right to bring in the cards but right now they're using my original images instead of my resized "variations". So firstly, I would like to know how to reference the variations of my images instead of using the original. Secondly, I need to grab only four of the cards from the Project page and not import in all ten. It should be just two small changes to my code to do these things (I would imagine). Here is the code I currently have for that section: <?php // https://processwire.com/api/arrays/ // check if the array of images has items if (count($pages->get("/projects/")->images)) : // get array of images from the field $images = $pages->get("/projects/")->images; $count = 0; // iterate over each one foreach ($images as $image) : $count++; $sectionText = $pages->get("/projects/")->get("paragraph_$count"); $img = $image; $buttonCode = $pages->get("/projects/")->get("url_$count"); ?> <span id="card<?php echo $count?>" class="card"> <img class="cardThumb" src="<?php echo $img->url; ?>" alt="<?php echo $image->description; ?> Thumbnail" /> <div class="cardBody"> <div class="cardText"> <h2><?php echo $img->description; ?></h2> <?php echo $sectionText; ?> </div> <div class="primaryBtn"> <a href="https://www.paypal.com/donate?hosted_button_id= <?php echo $buttonCode; ?> &source=url"> <button> <i class="fas fa-donate"></i> Donate </button> </a> </div> </div> </span> <?php endforeach; endif; ?> Thanks in advance for any help!
  16. I've searched, and maybe missed, the solution. I have a 'normal' images field and uploading images with a file size greater than 10Kb is fine. Any image size smaller results in the never-ending spinner and no upload. No min/max width/height set on image uploads in admin, ie just the defaults. Any ideas on how to fix? Using: PW: 3.0.175 PHP: 7.3 Marking it as "Resolved" rather than "Solved" as it auto-magically fixed itself. No idea whether PW, PHP, or just an internet hiccough... All good now 🤞
  17. Hello all, My page has a lot of images. I created a gallery_image field to upload and display them. Unfortunately they are sort of unordered in the backend, though the filenames are numbered sequentially. I understand that this reflects the order of finished uploads. I figured out how to sort them on the frontend, but is there a way to do the same in backend? I guess this HookAfterPagesSave.module found here https://processwire-recipes.com/recipes/extending-page-save-process/ might do the trick but I'm too new to processwire and too unexperienced in coding to see what code to write. Anyone can help? Thanks in advance Hanna
  18. Dear all, tomorrow I'll have to introduce some editors on how to upload and edit images in image fields in Processwire. The site in question is quite image rich and I've spent some time to serve the appropriate images via scrcset already cropped for different screen sizes. However, the backend offers a lot of possibilities to manipulate images and most of them I'm not familiar with because as a developer I've never spent much thinking on what all the features might be good for … Yet I'm concerned that my editors work on images in the backend may interfere with my optimization strategies in the templates. Is there a general rule of thumb what content editors should do or not do with images in order not to break srcset strategies etc.? Maybe there is already a source of information you could point me to? Your recommendations are much appreciated!
  19. Dear all, I'm upgrading an older side with the new custom fields for images feature as of 3.0.142. My image field is set to "Automatic" and holds a bunch of images together with their respective description on each page. New custom fields include "caption" among others and to make my live easier I I'm trying to populate "caption" with the value from the (default) description field. But unfortunately I can't seem to find out how to save the newly set values. This is my code: <?php foreach (page()->images as $image) { $image->set('caption', $image->description); bd($image->caption); echo files()->render("markup/views/view-card-image-fancybox.php", array('image'=>$image)); } ?> <?php $page->save(); bd($page->save()); ?> This sets the value as intended (see screenshot) but doesn't save it permanently to the database. What am I doing wrong? Thanks!
  20. I'm using hook for retrieving data from image metadata (IPTC) after image upload and filling them to some fields. When I choose server-side image resize, everything works well. But when I use client-side resize (which si much faster and client comfortable - it uses PWImageResizer.js) image metadata are lost during resizing - I have downloaded the file after resize and checked for EXIF, IPTC etc. and they are not present. Using PW 3.0.165. Tried to look into PWImageResizer.js but uhh it's too javascreepy to me:)
  21. I'm using custom fields for images (as mentioned here: processwire.com/blog/posts/pw-3.0.142) for a specific images-field, the images of which need to have an HTML-caption. It works fine so far. Now I'm trying to import pages that use this field. I first exported some pages of that kind to see what the spreadsheet would look like. It seems to not separate the captions for each images but instead put all images in one cell and all captions in another. How could I go about importing these pages and assign the captions to the images accordingly?
  22. I'm creating this site where a 'motherpage' renders all subpages. I switched on frontend editing to make editing as easy as possible to end-users. I'm stuck on adding images to the subpages. The frontend editor suggests to add images to the motherpage (that has no images field on it, nor should it), so it asks for another page to add the images to/from. Is there a way to make the frontend-editor context aware so that it looks for images in the correct subpage? I already tried the 'type C' approach and added <edit field="body" page="id">, but that doesn't seem to do the trick.
  23. Hi Everyone, I wish to display a gallery of images from multiple pages on the site. These images have custom fields created through page reference called 'furniture_list_type'. Each image now has a radio button which has been selected. In the example code below all images appear from the "gallery20", however the selector "gallery20.furniture_list_type=3390" does not have any effect. "3390" is the id of the page reference "chair" selected through the page reference. I wish only images selected as chair to show. Hope someone can help with this. Thanks, Calum $imagePages = $pages->find("template=makers-child, gallery20.furniture_list_type=3390") ; foreach($imagePages as $p) { echo "<ul>"; foreach($p->gallery20 as $image) { echo "<li><img src='{$image->url}'>{$image->furniture_list_type}</li>"; } echo "</ul>"; }
  24. so hello i am trying to combine my whole ass gallery with custom created watermark, i wanted to combine my images with simple text little opaque but that seemed harder and i couldnt make it work, well i cant make this work either, how are you handling watermarks? i would prefer if it would be plain PHP no imagemagick or some custom plugins scripts, but if neccesary i wont deny. so here's my code $pa = $pages->find("template=basic-page|art_gallery, images.tags!=''"); /* $pa = $pages->find("has_parent!=2,id!=2|7,status<".Page::statusTrash.",include=all"); */ echo "<div BRUUH class='row gtr-50 gtr-uniform js-filter' id='gal' >"; foreach ($pa as $p) { foreach($p->images as $image) { $obrazok = $image->url; $image = imagecreatefromjpeg($obrazok); $frame = imagecreatefromjpeg($pages->get('/settings/')->watermark->url); /* echo $image; echo $frame; */ # If you know your originals are of type PNG. imagecopymerge($image, $frame, 0, 0, 0, 0, 50, 50, 100); # Output straight to the browser. $img = imagepng($image); $options = array('quality' => 70, 'upscaling' => true, 'cropping' => 'center', 'sharpening'=>'medium'); $thumb = $img->size(400, 300, $options); $large = $img->size(1200, 0, $options); echo "<div class='$image->tags' class='col-4'>"; echo "<span style='overflow:hidden;'class='image fit'>"; echo "<a href='$large->url'>"; echo "<img class='uk-transform-origin-top-right' uk-scrollspy='cls: uk-animation-fade; repeat: false' src='$thumb->url' alt='$image->tags'>"; echo "</a>"; echo "</span>"; echo "</div>"; } };
  25. Hi everyone, Yesterday I began working on a module to create a filesystem abstraction for files and images using the Flysytem library (http://flysystem.thephpleague.com), out of the necessity of having the images copied (and probably linked) on Amazon S3 and other places like Dropbox. There two reasons why I decided to tackle this: 1 - When I work on the project in my machine, I need a way to automatically sync the images from the server and/or the external storage. When an image is added on the server and the database is imported on my local env, PW shows a blank thumbnail of it. The idea for the module if to check if the page image has a width == 0 and if it exists on the server, add it to the local filesystem. 2 - In the past, I had to move a large website to a different server in a hurry and a lot of images were left behind (it was a mess). So I'm planning for a possible future worst-case scenario of the server exploding 🙂 The code I quickly wrote is below (please bear with me that it's pretty raw at the moment). One thing I had to figure it out is why PW fires the Pageimage::size hook wherever a page is loaded in the admin, even though the thumbnails are already created. I was planning to save the image variations on S3 as well. Can someone clarify? I know that @LostKobrakai was working on a similar project, and so I would like to ask him and everyone else if you think I (and who may help) should evolve this idea into a full-featured module where the user can select which server (adapter) to use (AWS, Digital Ocean spaces, Dropbox etc.) <?php namespace ProcessWire; use Aws\S3\S3Client; use League\Flysystem\AwsS3v3\AwsS3Adapter; use League\Flysystem\Filesystem; use League\Flysystem\Adapter\Local; use Spatie\Dropbox\Client; use Spatie\FlysystemDropbox\DropboxAdapter; class ProcessFly extends WireData implements Module, ConfigurableModule { public static function getModuleInfo() { return array( 'title' => 'ProcessWire Flysystem Integration', 'version' => 001, 'summary' => 'Synchronize all the page assets uploaded through PW to a specified bucket in Amazon S3 and...', 'author' => 'Sérgio Jardim', 'singular' => true, 'autoload' => true, 'icon' => 'image' ); } public function init() { $this->client = S3Client::factory([ 'credentials' => [ 'key' => '', 'secret' => '', ], 'region' => 'sa-east-1', 'version' => 'latest', ]); $this->bucket_name = ""; $this->dir_name = "images"; $this->s3_adapter = new AwsS3Adapter($this->client, $this->bucket_name, $this->dir_name); $this->s3_filesystem = new Filesystem($this->s3_adapter); // DROPBOX $this->authorizationToken = ""; $this->dropbox_client = new Client($this->authorizationToken); $this->adapter_dropbox = new DropboxAdapter($this->dropbox_client); $this->dropbox_filesystem = new Filesystem($this->adapter_dropbox); $this->addHookAfter('Pages::saved', $this, 'checkImageS3'); // Download images that are not in local filesystem for whatever reason but are available in the remove one. $this->addHookAfter('InputfieldFile::fileAdded', $this, 'uploadImageS3'); // Fired when a file/image is added to a page in the admin // $this->addHookAfter('Pageimage::size', $this, 'uploadImageS3'); // Fired when a file is resized via API. Note: this hook is also called when the page is loaded in Admin. Need to know why. $this->addHookAfter('Pageimage::url', $this, 'redirectImageURL'); //Replace image URL for the S3 path } public function redirectImageURL($event){ if($event->page->template == 'admin') return; else $event->return = "https://s3-sa-east-1.amazonaws.com/[bucket name]/images/" . $event->object->page .
