Create a custom method for doing this, instead of doing it in
beforeValidate(). (You will have to change the $this->data a bit).
function checkCode() {
App::import('Core','Sanitize');
$clean = Sanitize::stripScripts($this->data['Comment']
['comment']);
$clean = Sanitize::stripWhitespace($clean);
$this->data['Comment']['comment']= $clean;
if(strlen($clean)==0){
return false;
}
else return true;
}
var $validate = array(
'comment' => array(
'rule' => array('checkCode'),
'required' => true,
'message' => 'Comment Field Cannot be
empty'));
