How can I pass a URL parameter into a hidden form field in Webflow?

To pass a URL parameter into a hidden form field in Webflow, you can follow these steps:

1. Create a form in Webflow: Begin by creating a form in Webflow where you want to pass the URL parameter value.

2. Add a hidden form field: Inside the form, add a hidden form field. This field will be used to capture and store the URL parameter value.

3. Access the URL parameter value: To access the URL parameter value in Webflow, you can use JavaScript. Add a Custom Code element to your page where the form is located.

4. Write JavaScript code: In the Custom Code element, write the JavaScript code that will extract the URL parameter value and populate the hidden form field with it.

• Start by defining a function that retrieves the URL parameter value using JavaScript's URLSearchParams API.

• Next, select the hidden form field using its CSS selectors and set its value to the retrieved URL parameter value.

  Here's an example code that can be placed inside a <script> tag within the Custom Code element:

  ```javascript

  ```

  Replace 'parameterName' with the name of the URL parameter you want to extract, and 'hiddenFieldSelector' with the CSS selector of your hidden form field.

1. Call the JavaScript function: Finally, call the populateHiddenFormField() function to trigger the population of the hidden form field with the URL parameter value.

With these steps, you'll be able to pass a URL parameter into a hidden form field in Webflow.
