Question

I am unable to find the issue. It is showing 404|Not Found
update.blade.php
#extends('main')
#section('content')
<h1>Update Post</h1>
<form method="POST" action="{{route('posts.update', $post) }}" >
#method('PUT')
#csrf
<input type="text" name="title"><br><br>
<input type="text" name="body"><br><br>

PostController.php (a resource controller)
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use App\posts;
use Sessions;
class PostController extends Controller
{
public function index()
{
$post = posts::all();
return view('post.index', compact('post');
}
public function create(Request $req)
{
return view('posts.create');
}
public function store(Request $request)
{
$post = new posts;
$post->title = $request->input('title');
$post->body = $request->input('body');
$post->save();
return redirect('/');
}
public function show($data)
{
$post = posts::findOrFail($data);
return view('posts.read', compact('post','$post'));
}
public function edit(posts $post)
{
return view('posts.edit', compact('post'));
}
public function update(Request $request, $id)
{
$request->validate([
'title'=>'required',
'body'=>'required'
]);
$post = posts::find($id);
$post->title = $request->get('title');
$post->body = $request->get('body');
$post->save();
return redirect('/');
}
}
route:
Route::resource('posts', 'PostController');
please tell me what is the issue in this.
one of the advice I got is to change the name of view file i.e update.blade.php to edit.blade.php. I don't know how does it help

Answer 1

The problem is that you are returning the view: view('post.edit').
But you say that the file is called update.blade.php.
So you will have to rename the file to edit.blade.php or you need to change your edit function as follows, so that it returns the update blade file:
public function edit(posts $post)
{
return view('posts.update', compact('post'));
}

Answer 2

First you should change edit.blade.php instead of update.blade.php
Second you should not call model like this use App/posts; It is wrong. It must be use App\Post; in your PostController
Third you should change edit() in your controller
public function edit($id)
{
$post = Post::find($id);
return view('posts.edit', compact('post'));
}
You should use $post->id instead of $postin your form action
#extends('main')
#section('content')
<h1>Update Post</h1>
<form method="POST" action="{{route('posts.update', $post->id) }}" >
#method('PUT')
#csrf
<input type="text" name="title"><br><br>
<input type="text" name="body"><br><br>
<button type="submit" class="btn btn-primary">Update</button>
</form>
#endsection
Then check
public function update(Request $request, $id)
{
dd($id);//check id before update
$request->validate([
'title'=>'required',
'body'=>'required'
]);
$post = posts::find($id);
$post->title = $request->get('title');
$post->body = $request->get('body');
$post->save();
return redirect('/');
}
