Display Plugin courses_format variables on Category layout

[ewadrel]

Hello,

i have a question on Edulearn template.
I want to display on a specific LAYOUT templates\edulearn\html\com_content\category\blog2.php , the variables used via your Plugin courses_format ($courses_location, $courses_duration…).
Here is my php file if you can help me please. Look line #105 and #109, I’m displaying <?php echo $params->get(‘courses_location’) ;?> but the variable is EMPTY.

<?php

Here is what I got so far :

I found here
https://techjoomla.com/developers-blogs/joomla-development/how-to-access-joomla-plugin-parameters-anywhere-inside-joomla-code.html

that I could call the variables of a plugin anywhere in Joomla but it doesn’t work. I have adapated the code but it doesn’t work.

//**********************

// Get plugin 'my_plugin' of plugin type 'my_plugin_type'
$plugin = JPluginHelper::getPlugin('system', 'courses_format');
 
// Check if plugin is enabled
if ($plugin)
{
    // Get plugin params
    $pluginParams = new JRegistry($plugin->params);
 
    $courses_location = $pluginParams->get('courses_location');
    $courses_duration = $pluginParams->get('courses_duration');
    //$param3 = $pluginParams->get('param3');
}

//**********************

Thank you for your input.
