 */
function _voen_registration_custom_validate(&$form, &$form_state){

}

Hi, Thy goal i want to achieve from the above code is that i want to hide the username field from the registration form and instead i want to concatenate the first and last name to make username by code before it goes to database.

However the problem is that the default validation of the user_register_form occur before my any code. So i am trying to invoke my custom validation method before the default validation of user_register_form so that it sets the default value of username field to ABC Name.

But still now when i submit the form it shows me the error of username is required.

How can i fix this. I have to do this via code not any other module.

i think you'll need to replace the core validation altogether (and therefore add the a parts of the core validation to your function) rather than just doing yours first.

Change this:

function _voen_registration_custom_validate(&$form, &$form_state){
  $form_state['values']['name'] = 'Abc Name';
}

To this:

function _voen_registration_custom_validate(&$form, &$form_state){
  form_set_value('name', 'Abc Name', $form_state);
}

Hi,
DId you have to override this?

function user_validate_name($name) {
  if (!$name) {
    return t('You must enter a username.');
  }

I still get an error saying Username is required.

Thanks,
V
