Custom redirect after form submit

Question

I have a form, which is a default block-administration form. It's the standard form people use to edit block contents, visibility etc. When the user saves the form, drupal redirects the user to the block admin page.

Now, i want to take the user to another page, eg. the home page, after submitting a block-administration form. There are several ways to achieve this, but drupal recommends using the hook_alter_form method as described here

I've written a .module file called 'formdest' containing the following:

function formdest_form_alter(&$form, $form_state, $form_id) {
switch ($form_id) {
case 'block-admin-configure':
    $form_state['redirect'] = '/home';
  break;
}
}

and the .info file to accompany it:

; $Id: custom.info,v 1.0 2011/01/01 21:55:00 author Exp $
name = formdest
description = form destination
package = Other
core = 6.x

version = "6.x"
project = "custom"
datestamp = "1229018427"

My custom module shows up in the module list and I can enable it, thus activiting the redirect. But when I test it, drupal still takes me to the block admin page instead of to the homepage..

There are no error messages in neither firebug or system log, so I'm a bit clueless. Any of you coding gods has any ideas?

Answer 1

Add a submit handler into hook_form_alter(), and set the override there.

function mymodule_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == 'my_form') {
     $form['#submit'][] = 'my_submit_handler';
  }
}

function my_submit_handler(&$form, &$form_state) {
  $form_state['redirect'] = 'home';
}

Its as simple as 1 2 3

1. Create a Custom page with just title i.e. Thank you for your contacting us. Now go to "URL path settings" of this page and un-check "Automatic alias" and type your custom page url i.e. thank-you.

2. Remove default URL aliases for web forms i.e. [node:title] and save settings. So that you page url would be site.com/thank-you

3. Edit that Web Form -> Go to Form Setting tab, in "Redirection Location" section set "Custom URL" as of your newly created page in step 1.

Enjoy!

I've been struggling with doing a dynamic redirect in drupal 6 based on where the user came from and here is what I came up with, I hope it helps someone else:

function mymodule_form_alter(&$form, &$form_state, $form_id){
   if($need_to_redirect){
        /*add a form field to the form, you could also add this value to a 
              session or cookie,but if the user is logged in/out based on this
              action the session will be rebuilt*/
        $form['my_redirect']=array(
            '#type' => 'hidden',
            '#value'=>isset($form_state['post']['my_redirect'])?$form_state['post']['my_redirect']:trim(parse_url($_SERVER['HTTP_REFERER'], PHP_URL_PATH),'/')
        );
   }
   if(isset($form_state['post']['my_redirect'])){
        /*if there is a redirect set for the form add an extra submit handler,
               this ensures that in cases like a node form our redirect will get
               set last*/
        $form['#submit'][]='my_custom_redirect';
        //unset this so it doesn't override our custom redirect
        if(isset($form['#redirect'])) unset($form['#redirect']);
    }
}
function my_custom_redirect($form,&$form_state){
    $router_item = menu_get_item($form_state['values']['my_redirect']);
    //make sure the user has access to this menu item, if not just ignore it
    if ($router_item && $router_item['access']) {
        $form_state['redirect']=$form_state['values']['my_redirect'];
    }
};

Obviously the $need_to_redirect should be replaced with a switch or if check depending on your form_alter preference
