Forms setup

Netlify comes with built-in form handling that's enabled by default. Our build bots do it by parsing your HTML files directly at deploy time, so there's no need for you to make an API call or include extra JavaScript on your site.

HTML forms

Code an HTML form into any page on your site, add data-netlify="true" or a netlify attribute to the

tag, and you can start receiving submissions in your Netlify site admin panel.

Your form's name attribute determines what we call the form in the Netlify app interface. If you have more than one form on a site, each form should have a different name attribute.

Here's an example:

Your Name:

Your Email:

Your Role: Leader Follower

Message:

Send

When Netlify bots parse the static HTML for a form you've added, they automatically strip the data-netlify="true" or netlify attribute from the

tag and inject a hidden input named form-name. In the resulting HTML that's deployed, the data-netlify="true" or netlify attribute is gone, and the hidden form-name input's value matches the name attribute of like this:

JavaScript forms

You don't need to include extra JavaScript on your site to use Netlify Forms. But, if you want to, you can use JavaScript to render a form client-side. You can also submit forms over AJAX/XHR.

Work with JavaScript-rendered forms

Our bots find your forms by parsing the HTML of your site when the build completes. This means that if you're using JavaScript to render a form client-side, our bots won't find it in the pre-built files. You can work around this by creating a hidden HTML form with the data-netlify="true" attribute and input fields with name attributes to match the inputs of your JavaScript-rendered form. You need to apply the same work around if you want to use our reCAPTCHA 2 integration, and create a div element in the hidden HTML with the data-netlify-recaptcha="true" attribute.

While the two articles are fairly framework-specific, the code demonstrates how to prerender forms when working with them in a web application.

Submit forms via AJAX

You can submit forms over AJAX/XHR as well, by targeting the AJAX request to an action attribute on the form.

Note that Netlify automatically adds a hidden field to your published form called form-name with a value to match the name attribute of the form when you submit an HTML form instead of building one with JavaScript. Make sure to include this field in your AJAX request!

Here's a simple jQuery example:

$("#my-form").submit(function(e) { e.preventDefault();

var $form = $(this); $.post($form.attr("action"), $form.serialize()).then(function() { alert("Thank you!"); }); });

Note that the content of the AJAX request must be URL-encoded. In the above example, the jQuery serialize() function handles the URL encoding. Netlify forms do not support JSON form data at this time.

Success messages

By default, when visitors complete a form, they will see a generically styled success message with a link back to the form page. You can replace the default success message with a custom page you create by adding an action attribute to the

tag, entering the path of your custom page (like "/pages/success") as the value. The path must be relative to the site root, starting with a /.

File uploads

Netlify Forms can receive files uploaded via form submissions. To do this, add an input with type="file" to any form.
