Can Webflow forms be pre-filled with information?
TL;DR
- Pre-fill Webflow forms using URL parameters, custom JavaScript, Webflow CMS, or third-party tools.
- Use query parameters in the URL and JavaScript to populate form fields dynamically.
- Embed custom JavaScript to extract values from the URL and insert them into form inputs.
- Bind form fields to Webflow CMS data for dynamic pages with stored user information.
- Autofill logged-in user data using Webflow Memberships or third-party tools like Make (Integromat) or Zapier.
Yes, Webflow forms can be pre-filled with information using URL parameters, custom JavaScript, or Webflow CMS. Here’s how you can do it:
1. Use URL Parameters
- Add query parameters to your form’s URL (e.g.,
?name=John&email=john@example.com). - Use Webflow's custom embed code to set these values in form fields using JavaScript manually.
2. Use Custom JavaScript
- Add a custom script inside a Webflow Embed element or in Page Settings > Custom Code.
- The script should read URL parameters and populate form fields using
document.querySelector(). - Example (inline approach):
document.querySelector('[name="name"]').value = new URLSearchParams(window.location.search).get('name');
3. Use Webflow CMS for Pre-Filled Fields
- Bind form fields to CMS collection fields in Webflow Designer.
- Useful when generating dynamic pages where user data is stored in Webflow CMS.
4. Autofill Logged-in User Data (With Memberships or Third-Party Tools)
- If using Webflow Memberships, you may retrieve logged-in user data with JavaScript and inject it into form fields.
- Third-party tools like Make (Integromat) or Zapier can also help pre-fill forms with user data.
Summary
You can pre-fill Webflow forms using URL parameters, custom JavaScript, Webflow CMS, or third-party integrations. This is useful for personalizing user experiences and streamlining form submissions.
