Custom Plugin Won't Work

Question

I'm trying to create a class in EE, but for some reason it just won't work for me. I've even went as far as making it as easy as possible, but I always get:

The following tag has a syntax error:

{exp:my_class_name:testfunction}

Please correct the syntax in your template.

Here's the simple class:

class My_class_name {

    public $return_data;

    public function __construct(){
        $this->EE =& get_instance();
    }

    public static function usage(){
        ob_start();
        ?>
        Coming Soon, this is just filler for now.
        <?php
        $buffer = ob_get_contents();
        ob_end_clean();
        return $buffer;
    }

    public function testfunction(){
        $this->return_data = ee()->TMPL->tagdata;
    }

}

and usage:

    {exp:my_class_name:testfunction}
    hey
    {/exp:my_class_name:testfunction}

Answer 1

Your plugin class method needs to return the (parsed) tagdata instead of setting the $this->return_data property. The latter is only needed if the class constructor is used for template output. So:

public function testfunction()
{
    return ee()->TMPL->tagdata;
}
