Form Validation : Using errors array.

Hi,

This is a basic question but again after lot of search I could not get how to do.

I am for the first time trying to place custom validations. I have created errors array in validations method of the form. But I do not know where to capture this array.


In a page, I am creating the form as

        $cnClHpsFrm = new cl_manage_form( $CFG->wwwroot . '/local/hps/cl_manage_hps.php?id='.$currCourseid,array('housesArr'=>$housesArr,'currCrseStudentsArr'=>$currCrseStudentsArr,'currCourseid'=>$currCourseid) );

In this same file, I have the three conditions for form cancel, submit and else.

Please help and guide.

Hi Bhargava,

You don't need to capture errors array to display error message during form validation. Moodle will automatically handle it internally .  You just need to use field name as a subscript of errors array for which you want to display error message.
For Ex -  If you want to check password should not be less than 5 character then the code inside validation function should be like that
if (!empty($data['password']) && strlen($data['password']) < 5) {
   $errors['password'] = " Password length should be more than 5";
}
This error message will automatically display above the password field if validation does not pass.
For more detail see : - https://docs.moodle.org/dev/lib/formslib.php_Validation
Hope this will help you.
