XF 2.2 Custom Page PHP Callback Not Displaying

[CommanderVex]

I have created a page node and trying to use xen:callback. However, nothing is displaying and is just a blank page.

I have a created a folder called Pages in src/addons with a file called Providers.php

Providers.php

<?php
namespace Pages;
class Providers
{
    public static function getHtml()
    {
        echo 'test';
        return 'test';
    }
}

Template

<xen:callback class="Pages\Providers" method="getHtml"></xen:callback>

Node Settings

 

[TMC]

<xen:callback class="Pages\Providers" method="getHtml"></xen:callback>

Try changing xen:callback to xf:callback.

Try changing xen:callback to xf:callback.

Why does it always have to be something so simple.....

Thank you
