I need to compare the text in the username field with the text in email field of the registration form. If they are not equal i want to stop the registration. I think i should use a hook but i really don't know where to start from.

Any idea?

You can do this by using hook_form_FORM_ID_alter() and adding an extra validation function to the user register form:

function MYMODULE_form_user_register_form_alter(&$form, &$form_state, $form_id) {
  $form['#validate'][] = 'MYMODULE_validate_register_form';
}

function MYMODULE_validate_register_form(&$form, &$form_state) {
  if ($form_state['values']['mail'] != $form_state['values']['name']) {
    form_set_error('name', t('Name and email must be the same.'));
  }
}

I'm not 100% positive those $form_state['values'] keys are the right ones so you'll need to inspect the form to make sure; but the logic is the same either way.

Maybe the Email registration module is something for you: http://drupal.org/project/email_registration

Allow users to register and login using only an email address. Users can then log-in using their email address and password for authentication.

  • I looked into that module but i think it could create some mess with the site. Since it is already up & running i don't think it's a good idea. – flero Jun 27 '12 at 7:26
  • The module just put's the given email address into the user name field. So if this is your current policy, this shouldn't be a problem. Of course you should test this kind of changes on a dev environment before putting it into production. – BetaRide Jun 27 '12 at 7:56
  • There is a half mess in that site and i don't want to create a bigger one... using a hook seems to be the cleanest solution. – flero Jun 27 '12 at 10:09

Clive's answer above is great, but if you prefer to work in the theme layer you can put this code into your theme's template.php file.

function MYTHEME_form_alter(&$form, &$form_state, $form_id){
  if ($form_id == 'user_register_form'){
    $form['#validate'][] = 'MYTHEME_validate_register_form';
  }
}

function MYTHEME_validate_register_form(&$form, &$form_state) {
  if ($form_state['values']['mail'] != $form_state['values']['name']) {
    form_set_error('name', t('Name and email must be the same.'));
  }
}

You can obviously change the validation statement to do whatever you want, you just have to make sure to pass "form_set_error()" to invalidate the form and display a message to the end user.

You can also use the Login Toboggon module to do all kinds of neat login-y things.

The LoginToboggan module offers several modifications of the Drupal login system in an external module by offering the following features and usability improvements:

  • Allow users to login using either their username OR their e-mail address.
  • Allow users to login immediately.
  • Provide a login form on Access Denied pages for non-logged-in (anonymous) users.
  • The module provides two login block options: One uses JavaScript to display the form within the block immediately upon clicking "log in". The other brings the user to a separate page, but returns the user to their original page upon login.
  • Customize the registration form with two e-mail fields to ensure accuracy.
  • Optionally redirect the user to a specific page when using the 'immediate login' feature.
  • Optionally redirect the user to a specific page upon validation of their e-mail address.
  • Optionally display a user message indicating a successful login.
  • Optionally combine both the login and registration form on one page.
  • Optionally have unvalidated users purged from the system at a pre-defined interval (please read the CAVEATS section of INSTALL.txt for important information on configuring this feature!).
  • Integrates with Rules module to do various tasks when a user validates via email validation process (see http://drupal.org/node/880904 for an example)
