405 Method Not Allowed

Error Message

405 METHOD_NOT_ALLOWED

Cause

The HTTP method used (GET, POST, etc.) doesn't match the route definition. The route exists but for a different HTTP verb.

Solution

Check the route definition for the correct HTTP method. Use the right form method in HTML (@method for PUT/DELETE). Verify the AJAX request method.

Code Example

Fix

// Route only accepts POST
Route::post('/posts', [PostController::class, 'store']);

// HTML forms need @method for PUT/DELETE
<form action="/posts/{{ $post->id }}" method="POST">
    @csrf
    @method('PUT')
    <button type="submit">Update</button>
</form>

// Check the correct route exists
Route::put('/posts/{post}', [PostController::class, 'update']);

Debugging Steps

Run php artisan route:list to check HTTP methods
Verify the form method attribute
Check AJAX request method
Ensure @method directive is present for PUT/DELETE/PATCH

Prevention

Use Route::resource() for consistent CRUD routes. Always include @method in HTML forms. Match form actions to route definitions.
