Understanding MethodNotAllowedHttpException and How to Solve It
Many developers come across the MethodNotAllowedHttpException error in Laravel and get stuck wondering what went wrong. The error usually points to a mismatch between the request method (GET, POST, PATCH, etc.) and the way routes are defined. Let’s walk through the most common causes and the right way to address them without dragging things out.
An Overview
Why MethodNotAllowedHttpException Occurs
A very common reason is defining a route with GET when the form or request actually uses POST. For example:
Route::get('/users', UserStoreController::class)->name('users.store');This will trigger the MethodNotAllowedHttpException if your form is sending data using POST.
Matching Routes with Form Requests
If your form posts data, your route must be defined as POST. Splitting the routing into GET and POST makes things much clearer.
Route::post('validate', 'MemberController@validateCredentials');
Route::get('validate', function () {
return View::make('members/login');
});And your controller method:
public function validateCredentials()
{
$email = Input::post('email');
$password = Input::post('password');
return "Email: " . $email . " and Password: " . $password;
}Using Named Routes
It is a good idea to use named routes, which make scaling easier.
Route::post('/validate', [MemberController::class, 'validateCredentials'])
->name('member.validateCredentials');And in your view:
<form action="{{ route('member.validateCredentials') }}" method="POST">
@csrf
...
</form>When PATCH is Needed
Sometimes the error happens because you are posting data where a PATCH request is required. In that case, add this hidden field:
<input name="_method" type="hidden" value="PATCH">This should be placed right after the Form::model line.
Correcting POST vs GET
Do not use a GET route when you are posting data. For example:
Route::get('/validate', 'MemberController@validateCredentials');should instead be:
Route::post('/validate', 'MemberController@validateCredentials');Resource Routes
Laravel resource routes handle GET, POST, PATCH, and DELETE automatically. For example:
Route::resource(‘file’, ‘FilesController’);
Then, in your form:
{{ Form::open(array('route' => 'file.store')) }}This approach avoids having to manually create multiple routes.
Query Builder Example
Another pitfall is using where()->get() which returns a collection instead of a single model. Instead of:
Employe_info::where('id',$id_to_update)use:
Employe_info::find($id_to_update)Even better, leverage route model binding:
// routes/web.php
Route::patch('/employe_infos/{employe_info}', 'Employe_infoController@update');
// Employe_infoController.php
public function update(Request $request, Employe_info $employe_info)
{
$attributes = $request->validate([
// validation rules here
]);
$employe_info->update($attributes);
return redirect()->route('show.employe')
->with('success_update', 'Informations were updated successfully.');
}API Routes and Postman
If you are working with APIs, remember to prefix your routes with /api. For example:
Route::post('/user','UserController@Register')->middleware('auth:api');And in Postman, the request should look like:
127.0.0.1:8000/userIf you miss adding /api when calling API routes, you’ll end up with a MethodNotAllowedHttpException.

Conclusion
The MethodNotAllowedHttpException in Laravel mostly comes down to a mismatch between the request method and the route definition. By carefully checking whether the form uses POST, PATCH, or GET, and making sure the routes are defined the same way, you can resolve this issue quickly and keep development moving.
