hi there,
i am clear with email validation, can i insert one more rule, for example something like the following code ?

Code:

$rules=array(
'field'=>'email',
'label'=>'E-mail',
'rules'=>'required'
'rules'=>'valid_email'
);

it doesn't work this way but i hope you get the idea
so how to build the rules to accept two 'rules' ->one for 'required', other for 'valid_email' ?
tnx.

To get more rules applied, just add them with pipe character:

Code:

$rules = array(
    array(
        'field' => 'email',
        'label' => 'E-mail',
        'rules' => 'required|valid_email'
    )
);
