[Drupal] How to implement confirmation form in Drupal 7

Confirmation form is useful in cases where we do some action that needs confirmation from the user. Drupal provides a function called confirm_form() that provides a confirmation form.

The confirm form contains a confirm button for confirming the action and a cancel link for cancelling the action. There should be a submit handler for the confirm submit button which do the corresponding actions. And the cancel link can be set to redirect to a page.

The following example shows the usage of confirm function.

Consider a menu "activity/%/delete".

  $items['activity/%/delete'] = array(
    'title' => 'Delete activity',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('my_module_delete_activity_form', 1),

The function in the page arguments provides the confirm form, which is passed as argument to the drupal_get_form. The "my_module_delete_activity_form" shows the way of using the confirm function.

The function confirm_form() has the following arguments.

  • The form elements: This argument specifies the form elements in the confirm form. We can add additional form elements if we want.
  • The question: This argument specifies the confirmation question.
  • The cancel path: This argument specifies the path to which the cancel link redirects.
  • Description: This argument specifies the additional text to display in the confirm form.
  • Confirm submit button caption: It specifies the confirm button Caption.
  • Cancel link caption: It specifies the cancel link caption.
  • Reference name: It specifies the reference name for the confirmation item.

The following example function shows the usage of confirm_form

  function my_module_delete_activity_form($form, &$form_state) {
    global $base_url;
    $account_id = arg(3);
    $form = confirm_form($form,
      'Are you sure, Do you want to delete?',
      'The action cannot be undone.',
    return $form;

When the "Delete" button in pressed the submit handler written for the confirm_form is called. The cancel link here redirects to the page activity-list. The submit handler can be like:

function my_module_delete_activity_form_submit($form, &$form_state) {
  // Required actions here

There is no argument in the function confirm_form to redirect to a page after the action is confirmed. For this we can specify a drupal_goto() in the submit handler of the confirm_form to redirect after the action is complete.

We have added a few new modules to our site recently. Drupal Technical StumbleThis Sean (not verified) access_time 21 Sep 2021 - 09:00 Hi there, I uploaded the files, enabled the modules to use SU, and now I see the link, but there is no icon... How can I fix this? Thanks, Sean webmaster access_time 21 Sep 2021 - 09:00 In reply to Icon doesn't show by Sean (not verified) What do you see when you view the source? Search for stumblethis_button and you should be able to see the code for the image and the URL. Then you should be able to troubleshoot from there.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where www.example.com and example.com leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but example.com will redirect you to www.example.com with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also. Drupal Technical Apache htaccess SEO Anonymous (not verified) access_time 21 Sep 2021 - 09:00 Hello. I'm trying to make example.com show as www.example.com, and I'm running into difficulties. I'm on Apache 2.0 and using the following lines in my httpd.conf file: RewriteEngine on RewriteCond %{HTTP_HOST} ^xxxxxxxxxx\.com$ [NC] RewriteRule ^(.*)$ http://www.xxxxxxxxxx.com/$1 [L,R=301] When I go to http://xxxxxxxxxx.com, I get http://www.xxxxxxxxxx.com (as expected). However, when I go to http://xxxxxxxxxx.com/node/1 (it's a Drupal site), I get a 404 thrown and the URL changes to xxxxxxxxxx.com/var/www/drupal/node/1. Same thing with www.xxxxxxxxxx.com/node/1. Any suggestions? I want to run without Drupal's .htaccess file (instead incorporating these calls into my httpd.conf file). webmaster access_time 21 Sep 2021 - 09:00 In reply to Rewrite including filesystem path by Anonymous (not verified) I think the problem is with the base path which results in the redirection to /var/www/ part. The best approach I would think is to start with drupal htaccess and then strip out parts and move to httpd SNVC (not verified) access_time 21 Sep 2021 - 09:00 This is definitely a good guide. Thanks for this. wellyson access_time 21 Sep 2021 - 09:00 This is really nice and helpful.

Thanks for the simple explanation.

Only thing I added was to add the $id as a function argument then store that in $form_state['storage']['id']; Then I will be able to use it in the submit function to delete
