Adding a back-door drupal login, when overriding login page
While creating an external login module, I wanted to modify the login block and page to provide the external login link and disable the Drupal username and password fields. However, I needed to create a different path that will still allow the superadmin user to login with his/her Drupal account.
I added this menu callback:
$items['backdoor'] = array('title' => 'Admin Login',
'description' => 'Use when can\'t login externally',
'page callback' => 'drupal_get_form',
'page arguments' => array('user_login'),
'access arguments' => array('access content'),
);
Then in the form_alter, I've disabled the username and password, except for the backdoor page:
function yourmodule_form_alter(&$form, $form_state, $form_id) {
switch ($form_id) {
case 'user_login':
case 'user_login_block':
// only allow for Drupal login fields if this is the /backdoor page
if (strcmp(current_path(),"backdoor")!=0) {
$form['name']['#access'] = FALSE;
$form['pass']['#access'] = FALSE;
$form['#submit'][] = 'yourmodule_external_submit';
unset($form['#validate']);
$form['#validate'][] = 'yourmodule_external_validate';
}
break;
