Quick check coding for Custom Placeholer.. Works fine… but.. well…
I don’t know enough about these things…

In Classes folder –> em_location.php

Particularily “ob_start();” and the other code “$replace = ob_get_clean();”
I don’t know enough about these things… if those are correct… but it works ??

case '#_LOCATIONICON':
	ob_start();
              $template = em_locate_template('placeholders/locationwhere.php', true, array('EM_Locations'=>$this));
              $replace = ob_get_clean();
break;

I know in the Tutorial you show how to do Custom Placeholders but I never could get that correct and the above works fine.

Thanks as always….
