Fixing Missing Required Parameters Error in Laravel AJAX Requests

When developing with Laravel, working with AJAX requests can sometimes lead to frustrating roadblocks, especially when it comes to route parameters. One common error you might encounter is:

Missing required parameters for [Route: sender] [URI: {name}/{code}] [Missing parameters: name, code]

This issue can arise when you attempt to send data via an AJAX request to a route that requires certain parameters. In this post, we’ll walk through the problem and provide a clear solution step by step.

Understanding the Problem

The error occurs when your AJAX call does not include the required parameters in its URL. For example, in your routes defined in web.php, you have:

When you send a POST request to the sender route, Laravel expects the {name} and {code} parameters to be present in the URL, but if they are missing, you’ll encounter the aforementioned error.

The Solution

To resolve this error, you need to make sure that your AJAX request includes the required parameters in the URL. Below are the steps to fix it.

Step 1: Update the Routes

If you want your routes to function correctly with AJAX, you can redefine them to include optional parameters or ensure they're always passed correctly.
