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.
Example 4-38. PHP execution file
<?php
if ($this->operation == $this->labels['Add']) {
return 'add mode selected';
} else {
return '<img src="tt.png" alt="TT">';
}
?>['sqlw'] option.
