Redirects the user to a URL after a form has been processed.

After a form was executed, the data in $form_state controls whether the form is redirected. By default, we redirect to a new destination page. The path of the destination page can be set in $form_state['redirect'], as either a string containing the destination or an array of arguments compatible with drupal_goto(). If that is not set, the user is redirected to the current page to display a fresh, unpopulated copy of the form.

For example, to redirect to 'node':

$form_state['redirect'] = 'node';

Or to redirect to 'node/123?foo=bar#baz':

$form_state['redirect'] = array(
    'query' => array(
      'foo' => 'bar',
    'fragment' => 'baz',

There are several triggers that may prevent a redirection though:

  • If $form_state['redirect'] is FALSE, a form builder function or form validation/submit handler does not want a user to be redirected, which means that drupal_goto() is not invoked. For most forms, the redirection logic will be the same regardless of whether $form_state['redirect'] is undefined or FALSE. However, in case it was not defined and the current request contains a 'destination' query string, drupal_goto() will redirect to that given destination instead. Only setting $form_state['redirect'] to FALSE will prevent any redirection.
  • If $form_state['no_redirect'] is TRUE, then the callback that originally built the form explicitly disallows any redirection, regardless of the redirection value in $form_state['redirect']. For example, ajax_get_form() defines $form_state['no_redirect'] when building a form in an Ajax callback to prevent any redirection. $form_state['no_redirect'] should NOT be altered by form builder functions or form validation/submit handlers.
  • If $form_state['programmed'] is TRUE, the form submission was usually invoked via drupal_form_submit(), so any redirection would break the script that invoked drupal_form_submit().
  • If $form_state['rebuild'] is TRUE, the form needs to be rebuilt without redirection.


$form_state A keyed array containing the current state of the form.
