How to Fix the 419 POST Error in Ajax Requests with Laravel?

Ajax LARAVEL 419 POST Error Resolved

This error typically occurs when attempting to make an Ajax POST request without proper CSRF token verification. Laravel implements CSRF token protection to prevent malicious requests from external sources.

Problem:

You are encountering a POST error when making an Ajax call to the /company endpoint.

Solution:

To resolve this issue, you need to include the CSRF token in your Ajax request. You can do this by adding the following code snippet to your Ajax call:

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});

This will add the generated CSRF token to the header of your Ajax requests, ensuring that Laravel can verify that the request is coming from an authenticated user.

Explanation:

Laravel automatically generates a unique CSRF token for each active user session. This token is stored in a meta tag in your HTML document:

<meta name="csrf-token" content="your-generated-token" />

When your Ajax call is made, the CSRF token must match the token stored in the meta tag. If they don't match, Laravel will reject the request with a 419 error.

Alternative Solution:

If you want to exclude certain URI paths from CSRF token verification, you can add them to the following array in the VerifyCSRFToken middleware:

protected $except = [
    '/route_you_want_to_ignore',
    '/route_group/*'
];
