Loading Thumbnail of a page Image Attribute in Concrete5

Question

I like to load a image attribute and assign a custom thumbnail named small (created in Dashboard > System > Files> Thumbnails) to the image.

I created a custom image attribute blogimage in a template. Loading the image attribute works. Just need to know how to load the custom thumbnail.

<?php
    $img = $c->getAttribute('blogimage'); ?>
    <?php if ($img): ?>
    <img src="<?php  echo ($img->getVersion()->getRelativePath()); ?>"/>
<?php endif; ?

Answer 1

If blogimage is the handle of a Image/File attribute, and $c is a Page instance, the following code

$img = $c->getAttribute('blogimage');

returns null if the page doesn't have a value for that attribute, or a Concrete\Core\Entity\File\File instance otherwise.

Then

$imgVersion = $img->getVersion();

returns a Concrete\Core\Entity\File\Version instance, which has the getThumbnailURL method.

So, in order to have the URL of the thumbnail type with handle small, you simply have to write this:

$img = $c->getAttribute('blogimage');
if ($img !== null) {
    $imgVersion = $img->getVersion();
    $thumbnailURL = $imgVersion->getThumbnailURL('small');
    ?><img src="<?= $thumbnailURL ?>" /><?php
