Now, when you visit the webform page, you should see the CAPTCHA field along with the form. Save the changes to your webform and make sure to clear the Drupal cache (admin/config/development/performance). Ensure that it's positioned above the "Submit" button so users see it before submitting the form. You can customize the label, description, and other settings. Configure the CAPTCHA component as needed. It's usually located under the "Advanced" category. In the webform builder, drag and drop the "CAPTCHA" component from the "Form components" section onto your form. Create or edit the webform you want to protect with CAPTCHA (admin/structure/webform). You can set the challenge type, difficulty level, and theme among other options. Configure the settings according to your preference. For webforms, "CAPTCHA point" is a good choice. Choose the CAPTCHA type you want to use. Go to the CAPTCHA module's configuration page (admin/config/people/captcha). Next, download and enable the CAPTCHA module from or through the admin interface (admin/modules). If not, download and enable it from the website or through the admin interface (admin/modules). First, make sure you have the Webform module installed. Here's a step-by-step guide on how to do it: In Drupal 7, you can easily add a CAPTCHA to a webform using the Webform module and the CAPTCHA module. So instead of webform-client-form-42 you enter webform_client_form_42.A CAPTCHA is a challenge-response test designed to protect websites from spam and abuse by distinguishing between human users and automated bots. It turns out that you need to convert all hyphens to underscores when you enter the form identifier. There is one slight issue though if you try to enter this identifier in the captcha the admin page will say Illegal form_id. For instance, if your form node ID is 42, the identifier will be webform-client-form-42. When you create a form, its node ID is used to generate an identifier that you can add to the recaptcha administration page, so automatically have the captcha challenge added to your form. It is very hard for software to decipher these words, so it makes the form useless for spammers. Very annoying.ĭrupal has a solution for this too the recaptcha module allows you to automatically place a widget on any form, that forces the user to enter two random words before the form can be submitted. Even if the form is not vulnerable, you'll still end up with hundreds or thousands of spam entries in the database and your email inbox. One problem with forms on web pages though, is that spammers tend to find them very quickly and try to find vulnerabilities in them that allow them to use the form to send email about viagra and cheap rolex watches to any number of unsuspecting victims. All without needing to write any PHP code. One of the great features of Drupal is that you can so easily extend its functionality with modules.įor example, the webform module allows you to gather information from users by creating forms using all available HTML form elements and then store these responses in a database and send an email.
