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">';
}
?>
This option is indended for advanced usage. Together with pre and before triggers, it allows tweaking the
core class without the need to hack it. To change input, use before triggers
or ['sqlw'] option.
