Cryptic Error Message When trying to Delete Images On a Page (PW 3.0.139)(Solved)

Hello Dear PW Gurus.

Hope you fair well in these Corona Crisis times.

Anyhow, i have a problem with a Cryptic error message that shows up when i am trying to Delete images out of a Images field.
The Error message does say a little but it does not make sense to me why i can´t delete the images because of it.

Is it some permission issue perhaps?

I will attach screenshots of it and what i did prior to it.
I am from sweden so ignore the funny words here and there.

Hope you all can send me on the right track.

i am running PW 3.0.139 on this install.

Step1:

Step 2: Select the images with the trashcan symbol

Step 3: Cryptic Error message

I am scratching my head on this one, have not seen this before.

Thankfull for all help.

It looks like you have a textformatter enabled for file descriptions. Try to de-activate that HTML purifier textformatter.

Hello Dragan.

Thanks for getting back to me, i tryed disabling the formating option you talked about but the same error message shows up.

Strange, i don´t get why.

I did some more investigating because no one seems to know why the error is happening.

I did the following.

1. Created an empty template file and uploaded to my PW install.
2. Created a completly new image field
3. Assigned that new image field to my template

4. i Created a hidden page with that template with the new image field
5. Uploaded five test images to that field on that page, saved it
6. Started edit on that page and deleted a random image

And for some strange reason there was no error message this time.

But the problem resists on the Page i mentioned in my original post.
Is there some kind of corruption somewhere i should look for?

Maybe i have to remove the page and add it again?

Now i have done the following:

I think the offending party in this drama was that "Images" field in the orignal Template.

I made a new template and a new Images field and transfered images to that, and now it seems to work fine.

Do not now why that Images field became corrupt, perhaps after an update to 3.0.139?

Made more testing with the what i thought was the "offending" images field in the first post.

And now i created a new test template and added that field to it and tested uploading images to it on a test page.

All of a sudden, no error message and the image was deleted as expected.

So this is just a very confusing event.

I am just glad that its seems to work again.

Wanted this thread to be here in case someone else got this problem and wanted a clue to how to solve it.

Also Enabling or Disabling the HTML Encoding formating for Filedescription output does not seem to mather which was the first thought after the tip by Dragan.

I just leave this here as info for others.

      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.

      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>"; } });

      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!

      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!

      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?
