There are many ways in which you can implement this feature yourself in
CakePHP. Here's one approach:
{{{
// in either your app_model.php or a model class
public function alnumWhitelist($data, $whitelist = array()) {
$data = array_values($data);
$check = $data[0];
$whitelist = implode($whitelist);
$rule =
"/^[\p{Ll}\p{Lm}\p{Lo}\p{Lt}\p{Lu}\p{Nd}{$whitelist}]+$/mu";
return preg_match($rule, $check);
}
// in your model validation rules
// Note that some special characters need to be properly escaped.
public $validate = array(
'name' => array(
'rule' => array('alnumWhitelist', array('\s', '\-', "\'",
'\"')),
'allowEmpty' => false
),
);
}}}
You can place the custom validation rule in a model, or make it available
on an application-level by putting it in your app_model. If you want to
get fancy you could also wrap up the validation rule in a behavior, add
test cases and put the whole lot in a plugin, which would make the whole
thing portable, re-usable and application independent.[[BR]][[BR]]
