I was hoping to be able to do this entirely in PHP but was having all kind of issues getting it to see my values as numbers instead of strings (got error messages because my PW debugging is currently set to true). I currently have about 10 cards that PW is generating that include thumbnails, descriptions, donation amounts (raised amounts and goal amounts), and donate buttons. What I was trying to do was take the goal amount divide it by the raised amount (using PHP) and simply insert that value into the Progress element's Value attribute. Sounded simple enough but I couldn't get PHP to simply divide those two fields. First I tried dividing the goal value by the raised value and inserting it into the value attribute, like so: <? php $raised = $page->get("raisedAmount$count"); $goal = $page->get("goalAmount$count"); $percent = $goalNum / $raisedNum; ?> <progress value="<?php echo $percent; ?>" max="100"></progress> Which gave me this error message: Uncaught TypeError: Unsupported operand types: string / string Then I tried converting the two strings to integers because apparently PHP couldn't detect they were numbers and do it, like so: <?php $raised = $page->get("raisedAmount$count"); $goal = $page->get("goalAmount$count"); $goalNum = (int) $goal; $raisedNum = (int) $raised; if ($raisedNum != 0) : $percent = $goalNum / $raisedNum; else: $percent = 0; endif; ?> <progress value="<?php echo $percent; ?>" max="100"></progress> but all of the progress bars remain at zero percent (not shown), even when I have values in some of the $raised variables. Please note, if I add this code: <?php echo $percent; ?> below the Progress element, it shows 0 on every single card, so the $percent is never calculated (as per the $percent = $goalNum / $raisedNum;) even though $raisedNum should not equal 0 during that iteration of the loop (the original code includes a loop, which I omitted to keep the code sections above smaller, notice the $count at the end of the $raised and $goal variable declarations). When the loop goes over "raisedAmount1" there is a value in there; however, after typecasting it to an integer ($raisedNum) the value is 0 for someodd reason instead of 40,000, which is what is in the $raisedAmount1 field in Processwire... I'm new to relatively new to PHP and Processwire and could really use some help on this one. Thanks in advance for any helpful replies! -
Lister Selector A Process module that uses Lister/ListerPro, but with a selector string input instead of the normal InputfieldSelector filters. Features For power users, typing a selector string is often faster and more intuitive than fiddling with InputfieldSelector. It also lets you copy/paste selector strings that you might be using somewhere else in your code. Allows the Lister rows to be sorted by multiple fields (not possible in Lister/ListerPro) Allows the use of OR-groups (not possible in Lister/ListerPro) If ListerPro is installed you can run ListerPro actions on the listed pages - the available actions are defined in the module config. Bookmarks can be configured in the module config and accessed via the flyout menu for the module page. For your convenience you can copy/paste a bookmark string from the note at the bottom of the Lister Selector results. Usage Type your selector string on the Selector tab. The selector is applied when the "Selector string" field is blurred, so hit Tab when you have finished typing your selector. Unlike Lister/ListerPro, you can't sort results by clicking the column headings. Control the sort within the selector string instead. Superusers can jump to the module config (e.g. to create a bookmark) by clicking the cog icon at the top right of the module interface. The module is mostly intended for use by superusers, because in most cases site editors won't understand the ProcessWire selector string syntax. If you want another role to be able to access Lister Selector then give the role the "lister-selector" permission. Only superusers can define bookmarks because in ProcessWire module config screens are only accessible to superusers. Screenshots Process page Module config (when ListerPro is installed) Advanced If for any reason you want to create dynamic bookmark links to Lister Selector for a given selector you can do that like this: /** @var $pls ProcessListerSelector */ $pls = $modules->get('ProcessListerSelector'); // Define selector $selector = "template=foo, title%=bar"; // Define columns (optional) $columns = 'title,modified'; $pls_link = $pls->getProcessPage()->url . '?bm=' . $pls->urlSafeBase64Encode($selector . ':' . $columns); echo "<a href='$pls_link'>My link</a>"; https://github.com/Toutouwai/ProcessListerSelector https://modules.processwire.com/modules/process-lister-selector/

Hi all, I need to loop over several images with an ordinary foreach - nothing fancy. However, each image needs to have a unique css class name attached. Here is a simplified example: <ul> <li><img class='mac' src='#'</li> <li><img class='ipad' src='#'</li> <li><img class='ipod' src='#'</li> </ul> and so on. My array of images will be a collection from several pages. So the information about the required class needs to be "attached" to the image somehow. Sure I could use the description field for that, but that's kind of a hack I would like to avoid for the sake of unexperienced editors. My PW skills got a bit rusty the last time. Maybe an easy way to achieve that as been already introduced into the core and I missed it. Apologies in advance if this is a silly question than ... Ideas welcome! Thanks.

Hello there. Since this is my first post in these forums: Thank you Ryan for ProcessWire and thanks to everyone that is supporting him or other users. I'm having a strange problem using $image->description. When I'm logged in as the default user I registered during install everything's working as expected. $image->description returns the string provided in the backend. Anyways if not logged in, an empty string will be returned resulting in <img src="url-is-still-working" alt="">. I don't really know whats going on. Might be a bug? Here's some code: $slides = ''; foreach ( $page->slideshow_images as $image ) { $slides .= '<li><img src="' . $image->url . '" alt="' . $image->description . '"></li>'; } I'm running ProcessWire 2.5.3.
