Hi grigri,
I've just tried your solution : as in : `/^\w+$/`
It doesn't work... if I type some French accented characters or "-" in
an input called "prenom".
Here is my $validate rule :
public $validate = array(
'prenom' => array(
'minLength' =>
array(
'rule' => array('minLength','2'),
'message'=>'My error message 1'
),
'custom' =>
array(
'rule' => '/^\w+$/',
'message' => 'My error message 2'
)
)
