    This blog describes about how to redirect users after logged into a site in Drupal 7. By default, Drupal redirects users to user page after logged into a site.  Suppose you want to redirect users into any other pages as you want. Then you can done that in Drupal 7.

     Drupal provides hook called hook_user_login to make changes while user login successfully. Let see the below code.

/**
 * Implement hook_user_login()
 */
function phponwebsites_user_login(&$form, &$form_state) {
 //add page here to where you want redirect users after login
  $form['redirect'] = '<front>';
}

    Now you can check whether you redirect to front page or not after login. Now  Drupal will be redirect you to front page.

Redirect users after logged into a site using custom form submit:

   Drupal have alternate method to redirect users after login. Ie, You need to add custom form submit handler to a form using hook_form_alter(). Then add a page to redirect users in that custom form submit handler in Drupal 7. Let see the below code.

/**
 * Implement hook_form_alter().
 */
function phponwebsites_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == "user_login" || $form_id == "user_login_block") {
    $form['#submit'][] = 'phponwebsites_custom_login_submit';
  }
}  
function phponwebsites_custom_login_submit(&$form, &$form_state) {
  //page to be redirect
  $form['redirect'] = '<front>';
}

Now you will be redirect to front page after logged into a drupal site. Now I’ve hope you should know how to redirect users after logged into a site in Drupal 7.
