4.9. PHP expressions

PHP feature allows user to display any HTML code in place of a value. Behavior is the same as in triggers.

If PHP option is set, a file of that name is included (and executed). All variables avaliable in the core class are available in the included PHP file.

<?php
	if ($this->operation == $this->labels['Add']) {
		return 'add mode selected';
	} else {
		return '<img src="tt.png" alt="TT">';
	}
?>
