How can I autofill a Webflow membership site form email field with the logged in user's email?

To autofill the email field in a Webflow membership site form with the logged-in user's email, you can use Webflow's logic features. Here's how you can do it:

​

1. Enable Membership Features

• Go to the Webflow dashboard and open your project.
• Navigate to the Memberships panel and ensure that membership features are enabled and configured.

​

2. Create a Form

• Open the page where you want the form.
• Add a Form Block from the Add Elements panel.

​

3. Set Up the Email Field

• Select the email field in the form.
• Assign an ID to this field such as email-field for easy reference.

​

4. Use Custom Code to Autofill

• Open the Page Settings of the page with the form.
• Add custom code in the Before Body Tag section to autofill the email. Here's how:
• Use JavaScript to access Webflow's user data object once the user is authenticated.
• Example:

    ```javascript

    <script>

      document.addEventListener('DOMContentLoaded', function() {

        var memberData = window.Webflow?.membership?.currentMember?.data;

        if (memberData) {

          var emailField = document.getElementById('email-field');

          emailField.value = memberData.email;

        }

      });

    </script>

    ```

• Ensure that the code is saved and republish your site.

​

5. Test the Autofill Functionality

• Log in as a member and navigate to the page with the form.
• Ensure that the email field is automatically filled with the logged-in user's email.

​

Summary

By utilizing Webflow's membership features and a bit of custom script, you can automatically fill a form's email field with the authenticated user's email on your Webflow site. This involves setting up membership settings, adding a form, uniquely identifying the email field, and using JavaScript to populate it from Webflow's membership data object.
