The POST method is not supported for this route. - Laravel - php

Question

I have a problem with my create post page. When I submit I get this error:
The POST method is not supported for this route. Supported methods: GET, HEAD.
I have no clue where it comes from as I am pretty new to Laravel.
routes(web.php):
<?php
Route::get('/', [PagesController::class, 'index']);
Auth::routes();
Route::get('/blog', 'App\Http\Controllers\PostsController#index');
Route::get('/blog/create', 'App\Http\Controllers\PostsController#create');
Route::get('/logout', 'App\Http\Controllers\Auth\LoginController#logout', function (){
return abort(404);
});
Route::get('/home', 'App\Http\Controllers\HomeController#index');
Controller:
public function index()
{
return view('blog.index')
->with('posts', Post::orderBy('updated_at', 'DESC')->get());
}
public function create()
{
return view('blog.create');
}
public function store(Request $request)
{
$request->validate([
'title' => 'required',
'description' => 'required',
'image' => 'required|mimes:jpg,png,jpeg|max:5048'
]);
$newImageName = uniqid() . '-' . $request->title . '.' .
$request->image->extension();
$request->image->move(public_path('images'), $newImageName);
Post::create([
'title' => $request->input('title'),
'description' => $request->input('description'),
'slug' => SlugService::createSlug(Post::class, 'slug',
$request->title),
'image_path' => $newImageName,
'user_id' => auth()->user()->id
]);
return redirect('/blog')
->with('message', 'Je post is toegevoegd!');
}

Answer 1

You are using get for all your routes... You have to use Route::post... Read the documentation again about this topic so you can understand it better.
Remember that using Route::post, Route::get, Route::delete and more, is the method you are allowing the route to be accessed with.

Answer 2

It comes from your Routes:
Route::get('/', [PagesController::class, 'index']);
Auth::routes();
Route::get('/blog', 'App\Http\Controllers\PostsController#index');
Route::get('/blog/create', 'App\Http\Controllers\PostsController#create');
Route::get('/logout', 'App\Http\Controllers\Auth\LoginController#logout', function (){
return abort(404);
});
Route::get('/home', 'App\Http\Controllers\HomeController#index');
You have GET routes, but no POST routes. You need Route::post in order to support POST.

Answer 3

You syntax for registering the route for post method is incorrect.
It should be: Route::post($uri, $callback); where callback can be any function in controller layer or service layer.
If you want to register your route for multiple http verbs, you can do so using any of the below methods.
Route::match(['get', 'post'], '/', function () {
//
});
Route::any('/', function () {
//
});
Refer to this documentation. It explains the concept in simple terms.
