Can I set a form_state redirect with a destination parameter in form submission?

I've built a "Quick Links" drop-down select box for my Drupal-based web app. The select box is implemented as a standard Drupal form, which appears on all pages in the site. When the user selects an option and submits the form, I want to redirect the user to the appropriate page, but have them return to the original page when they have finish开发者_JS百科ed.

e.g. user is on node/5, and selects a quick link which takes them to another form. When they have completed this form, I want them to be returned to node/5.

I have achieved this in other parts of the system using drupal_get_destination to append the ?destination=node/5 querystring parameter to the destination form, and this works nicely. However, in my quicklinks form submit handler, I'm setting form_state['redirect'] to set the target page, and if I add the ?destination= parameter it gets URL-encoded, and so isn't picked up when my target form is submitted.

function dh_seo_quick_links_form_submit($form, &$form_state) {
  $form_state['redirect'] = $form['#link_targets'][$link].'?'.drupal_get_destination();
}

Have I gone about this completely the wrong way? Is this redirection even possible? Could I do something clever with the $_REQUEST variables directly?

Here's a nice solution for Drupal 7 which allows you to use relative paths:

$form_state['redirect'] = array(
  'node/[node number]',
  array(
    'query' => array(
      'variable_name' => 'value',
    ),
    'fragment' => 'hash_fragment'
  ),    
);

This code creates the following url:

..?node/[node number]&variable_name=value#hash_fragment

This allows you a lot of flexibility while taking advantage of the Drupal framework.

OK - I've worked it out. It seems that if you set a relative URL in the $form_state['redirect'] it gets URL-encoded, but an absolute URL will not:

$form_state['redirect'] = 'myform?'.drupal_get_destination();

redirects to myform%3Fdestination%3Dnode%252F5

global $base_url;
$form_state['redirect'] = $base_url.'/myform?'.drupal_get_destination();

redirects to myform?destination=node/5, which is what I wanted.

You can supply an array for $form_state['redirect'] and put the destination query as second parameter. For example:

$form_state['redirect'] = array(
 'myform', array('query' => drupal_get_destination()),
);

You're answer worked for me Mark. Thanks!

You can do it this way also:

global $base_url;
$form['#redirect'] = $base_url .'/'. $form['#redirect'] .'?test=hello';

---

Finally I got this solution:

global $base_url;
$form_state['redirect'] = $base_url . '/myform?' . drupal_get_destination();
