I'm writing a form class which can also validate the form and I want to
define the rules for validating the forms, so when defining the form I can add
$form->AddRule('{pass1}=={pass2}','The 2 passowrd must be equal');
And this rule will be expanded to
$a = $GLOBALS["pass1"]==$GLOBALS["pass2"]
and validated through eval.
When I call the
$form->validate();
The class iterates through the rules array and in case of unmet condition
(!$a) will return the error string associate with the rule.
This method gives a great flexibility, ans as a result I can define any rule
as long as it is a valid php code.
Hope you get the idea
