Simple Joomla plugin not working on frontend

Question

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?

Answer 1

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)
