Laravel 5.5 ajax call 419 (unknown status)

📝 Title: Troubleshooting Laravel 5.5 Ajax Call 419 (Unknown Status) 🚀

Are you struggling with the "419 (unknown status)" error while making an Ajax call in Laravel 5.5? Don't worry, we've got you covered! In this blog post, we'll dive into the common issues behind this error and provide you with simple solutions to fix it. Let's get started!

🤔 Understanding the Error

When performing an Ajax call in Laravel, the "419 (unknown status)" error typically arises due to CSRF token verification failure. This security mechanism ensures that all requests originate from your own application and prevents cross-site request forgery attacks.

However, in your case, you mentioned that you don't have a form. So, how can you fix this error without a form? Let's explore the solutions!

🛠️ Solution 1: Generate CSRF Token

To resolve the "419 (unknown status)" error, you can generate a CSRF token manually and include it in your Ajax call headers. Here's how to modify your JavaScript code to add the CSRF token:

$('.company-selector li > a').click(function(e) {
     e.preventDefault();

     var companyId = $(this).data("company-id");

      $.ajax({
          headers: {
          'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
          },
          url: '/fetch-company/' + companyId,
          dataType: 'json',
          type: 'POST',
          data: {},
          contentType: false,
          processData: false,
          success: function(response) {
               console.log(response);
          }
     });
});

By including the 'X-CSRF-TOKEN' header, you're explicitly passing the CSRF token to Laravel and ensuring its validation. This should resolve the error and allow you to proceed with your Ajax call smoothly.

🛠️ Solution 2: Adding CSRF Middleware

While the previous solution works, Laravel provides a cleaner approach by utilizing CSRF middleware. Follow these steps to enable CSRF middleware for Ajax calls:

1. In your JavaScript file, make sure you include the 'csrf_token' meta tag:

<meta name="csrf-token" content="{{ csrf_token() }}">

1. In your app/Http/Kernel.php file, add the \Illuminate\Foundation\Http\Middleware\VerifyCsrfToken::class middleware to the web group:

protected $middlewareGroups = [
    'web' => [
        // Other middleware.....
        \Illuminate\Foundation\Http\Middleware\VerifyCsrfToken::class,
    ],
];

By adding the middleware, Laravel will automatically verify the CSRF token for all incoming requests made through the web group, which includes most typical Ajax requests.

Now, with the CSRF token validation enabled, the "419 (unknown status)" error should no longer bother you!

🔍 Troubleshooting the Controller Method

Since your ultimate goal is to display data from the response in an HTML element, let's ensure your controller method is correctly set up. Based on your provided code, it seems to be fine. However, to display the response data, you need to return JSON from your controller. Here's a slight modification to your existing code:

/**
 * Fetches a company
 *
 * @param int $companyId
 *
 * @return JsonResponse
 */
public function fetchCompany($companyId)
{
    $company = Company::findOrFail($companyId);

    return response()->json($company);
}

In the updated code, we used findOrFail to retrieve the company based on its ID. Additionally, we changed the return type hint to JsonResponse for clarity.
