To use a PHP cURL POST Request for a form on Webflow to send form data to an external database, follow these steps:

  1. Create your form in Webflow: Start by creating a form in Webflow with the necessary input fields that you want to submit to the external database. Make sure to give each input field a unique name attribute.

  2. Set up an endpoint on your server: You will need to have a server-side script that will handle the cURL request and process the form data. Set up an endpoint on your server (e.g., a PHP file) where you will handle the POST request.

  3. Retrieve form data in PHP: In your PHP file, use the $_POST superglobal to retrieve the form data. You can access form fields by their name attribute (e.g., $_POST['name'], $_POST['email'], etc.).

  4. Create a cURL request: Use the curl_init() function to initialize a new cURL session. Set the necessary options for the request, including the URL of the external database and the request method (POST). Add the form data as post fields using the CURLOPT_POSTFIELDS option. Set other relevant options like headers if required.

  5. Execute the cURL request: Use the curl_exec() function to execute the cURL request. This will send the form data to the external database.

  6. Handle the response: You can handle the response returned by the cURL request using the curl_getinfo() and curl_errno() functions. Check for any errors and process the response accordingly.

  7. Process the form data on the server-side: Once the form data is submitted to the external database, you can perform any necessary validation, sanitization, and database inserts or updates as required.

  8. Redirect or display a success message: After the data has been processed, you can redirect the user to another page or display a success message on your Webflow site.

Using this method, you can securely send form data from Webflow to an external database using a PHP cURL POST request.
