I have a simple Joomla 3 plugin that works fine on backend for resizing images when uploading from multimedia manager:

<?php

defined('_JEXEC') or die('Restricted access');

class PlgContentProcesador extends JPlugin
{
    protected $allowedMimeTypes = array('image/jpeg', 'image/png', 'image/gif');


    public function onContentAfterSave($context, $article, $isNew)
    {
        if ($context == 'com_media.file') {
            JFactory::getApplication()->enqueueMessage('Filepath: ' . $article->filepath);
            if ($article->type == 'image/jpeg' or $article->type == 'image/png') {
                $orig_image = new JImage($article->filepath);
                // 750 will be set accordind to image ratio depending on 1000
                $resized_image = $orig_image->resize(1000, 750, true, JImage::SCALE_INSIDE);
                $resized_image->toFile($article->filepath);
            }
        }
    }
}

I need to work the same on upload frontend in article submission, but when changing the context to com_content.form, nothings works. The variable $article seems not retrieve any data.

Any suggestions?

  • Though not an issue for this snippet, I would urge you to not use or in conditions with multiple expressions because or has the lowest precedence of all operators and can sometimes cause buggy/unexpected problems. Welcome to JSE and please take our tour.

  • Have you checked the value of $article? It should be an instance of Joomla\CMS\Table\Content. It's not going to have the same properties as a media file.

  • How can I check that value? I tried with var_dump but nothing showing up. Jan 27 at 14:31
  • You need to exit after var_dump() because a redirect is performed afterwards.

  • Thank you. Now I can see that the $article variable doesn't contain the path, so I'll try another approach to the problem. Jan 28 at 14:15

I think you just need to pass the $article parameter in as a reference. Add a & before the $article variable in the function call.

So, to change...

public function onContentAfterSave($context, $article, $isNew)

...to...

public function onContentAfterSave($context, &$article, $isNew)
