Code

function email_registration_user_login_validate($form, &$form_state) {
  $name = NULL;
  if (isset($form_state['values']['name']) && valid_email_address($form_state['values']['name'])) {

    // Try to load the username matching the email, if any exists.
    $name = db_select('users')
      ->fields('users', array(
      'name',
    ))
      ->condition('mail', db_like($form_state['values']['name']), 'LIKE')
      ->execute()
      ->fetchField();
  }

  // If the value is set, and a valid email, and a match was found, use it.
  if (!empty($name)) {

    // Keep the email value in form state for further use/validation.
    $form_state['values']['email'] = $form_state['values']['name'];

    // If the name matches an e-mail, assume that it's the desired name and
    // set the username in the form values.
    $form_state['values']['name'] = $name;
  }
  elseif (!variable_get('email_registration_login_with_username', TRUE)) {

    // If no username was found for the e-mail, and registration with username
    // is not allowed, unset the name from the form. This prevents
    // user_login_authenticate_validate() from trying to load a user from the
    // value as a username, which in turn causes user_login_final_validate()
    // to set a form error telling the user that no account has been found.
    // We have to set this to NULL rather than FALSE, because
    // user_login_name_validate() uses isset() rather than empty().
    $form_state['values']['name'] = NULL;
