Possible bug in file and image inputfield

Hi there! And thanks for Processwire!

It appears there's a possible bug in Processwire 3.0.170 concerning file and/or image inputfield. Creating such a field results in the following error:

Fatal Error: Uncaught Error: Call to a member function get() on null

The inputfield is created however. The closer look reveals a problem at line 60 in wire\modules\Fieldtype\FieldtypeFile\config.php:

if(!$value) $value = $fieldtype->get('defaultFileExtensions');

Commenting this line removes the problem, but the newly created inputfield requires 'Allowed file extensions' config option to be set (which is rather expectable since i commented the above-cited line of code). Never faced this problem before, hope it can be resolved.

      Hi,
      I'm facing the issue where a customer has only 1GB of RAM on its server available (and doesn't want to upgrade).
      They have a few large files (videos) that they want on the website but when uploading via the processwire backend the progress bar gets stock after some time (assuming because it ran out of RAM).
      I see that files are saved to site/assets/files/1048 and 1048 being the page id. I tried uploading the files via ftp (to avoid the shortage of RAM) to the same folder but the images don't appear in the files field.
      I'm assuming the files field is just an array with the file names that are then searched in site/assets/files/1048 . Is there a way where I can have the field look for other files in that folder and have it automatically added to the array so it appears in the files field of the page?
      My attempt didn't work and I didn't quite understand why:
      $directory = "../../files/1048"; // files uploaded here via ftp $page->of(false); foreach (scandir($directory) as $file) { //go through all files if ($file !== '.' && $file !== '..') { echo $file; $page->file->add($file); } } $page->save(); $page->of(true);

      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.

      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!

      It's been twice this year as a PW developer where clients have asqued me to have a way to put content on specific coordinates of a picture. Something like what image maps are made of. But not necesarly on links, sometimes text, sometimes images and links. 
      So I've been thinking to build an inputfield for that purpose. But I'm not sure how could it be the most flexible so I can share it in github/modules page.
      Ideally it would need to work like a repeater field where you start uploading an image and then adding any custom field like title, url etc. So the user could add multiple elements floating over that image.
      Does anybody here know the ideal way to start the arquitecture of something like that? I could just hardcode the fields I need for the website I have to code this month but it would be nice to be something more flexible.
