Solving Laravel MethodNotAllowedHttpException (5 solutions)

The MethodNotAllowedHttpException in Laravel usually arises when the HTTP method specified in the request does not align with the methods defined in your routes for a given URI. Below are common reasons and solutions for this error.

Solution 1: Verify Route Definitions

Ensure that you are sending a request to a route with the correct HTTP method as defined in your routes file.

• Check your web or API routes file (usually web.php or api.php in the routes folder).
• Look for the URI causing the problem and verify that the request method (GET, POST, PUT, PATCH, DELETE) matches your intention.
• Run php artisan route:list to list all registered routes and inspect their methods.

Example: If your client sends a POST request, your route definition should look like this:

Route::post('example', 'ExampleController@store');

Solution 2: Update Form Methods

HTML forms do not support PUT, PATCH, or DELETE methods directly. So, if you’re using these HTTP methods, you’ll need to include a hidden method field in your form.

• Add @method('PATCH') or another applicable method directive inside your Laravel collective form or HTML form element.
• Ensure your route and form method directives align.

Example:

<form action="/example" method="POST"> 
  @csrf @method('PUT') 
  ...other form elements... 
</form>

Solution 3: CSRF Token Inclusion

Missing CSRF tokens can lead to a MethodNotAllowedHttpException.

• Ensure that a CSRF token field is included in your forms for non-GET requests.
• If using AJAX, include the CSRF token in the request header or data payload.

Just review your code and Include the following in your HTML form: @csrf.

Notes: For AJAX, update headers globally using jQuery:

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

Solution 4: Clear Route Cache

Caching issues sometimes cause this problem. Clearing the route cache can help.

• Run php artisan route:clear to clear the route cache.
• If necessary, also clear application cache and config with php artisan cache:clear and php artisan config:clear.
• Rerun your application and test the route again.

As this is a command line operation, no code modification is needed beyond the artisan commands provided.

Solution 5: Middleware Configuration

Misconfigured or improperly ordered middleware can cause routing issues.

• Review your middleware sequence and ensure it’s properly ordered in your HTTP kernel.
• Make sure no middleware is inadvertently altering the request method.

Notes: Middleware order is crucial as they are processed in sequence and can modify the request.
