How do I update data in the database in laravel?-CodePudding

Here is my code so far: Controller:

public function edit($id){ $post = Posts::find($id);

    return view('edit', compact('post'));
}

public function update(Request $request, $id){
    $post = Posts::find($id);
        
    $validatedRequests = $request->validate([
        'title' => 'required|max:255|string|integer',
        'description' => 'required|max:255|string|integer',
        'price' => 'required|integer|max:255|'
    ]);

    $post->create($validatedRequests);
        
    return redirect('/Post/{{$post->id}}')->with('mssg', 'updates successfully');
}

Web.php:

Route::get('/post/{id}/edit', [PostController::class, 'edit']);

Route::put('/post/{id}/update', [PostController::class, 'update']);

View:

<form method="POST" action="/post/{{$post->id}}/update">
    @csrf
    @method('PUT')
    <label  for="title">change title:</label></br>
    <input type="text" name="title" value="{{$post->title}}"></input></br>
    <label  for="decsription">change description:</label></br>
    <input type="text" name="description" value="{{$post->description}}"></input></br>
    <label  for="price">change price:</label></br>
    <input type="text" name="price" value="{{$post->price}}"></input></br>

    <input type="submit" value="submit">
</form>

In your controller

public function edit(Request $request, $id)
{
   $post = Post::find($id);
   $post->title = $request->title;
   $post->description = $request->description;
   $post->price = $request->price;
   $post->save();
   return redirect('/Post/{{$post->id}}')->with('mssg', 'updates successfully');
}

Your Route

 Route::post('/post/{id}/edit', [PostController::class, 'edit']);

Your view

<form method="POST" action="/post/{{$post->id}}/edit">
@csrf
<label  for="title">change title:</label></br>
<input type="text" name="title" value="{{$post->title}}" required></input></br>
<label  for="decsription">change description:</label></br>
<input type="text" name="description" value="{{$post->description}}" required></input></br>
<label  for="price">change price:</label></br>
<input type="text" name="price" value="{{$post->price}}" required></input></br>

<input type="submit" value="submit">

Your Controller should be:

public function edit(Request $request, Post $post) {
        $validatedRequests = $request->validate([
            'title' => 'required|max:255|string|integer',
            'description' => 'required|max:255|string|integer',
            'price' => 'required|integer|max:255|'
        ]);    

        $post->update([
            'title' => $request->title,
            'description' => $request->description,
            'price' => $request->price    
        ]);    

        $post->save();

        return redirect('/Post/{{$post->id}}')->with('mssg', 'updates successfully'); 
}

Your Route

 Route::post('/post/{post:id}/edit', [PostController::class, 'edit'])->name('post.update');

Your View should be:

<form method="POST" action="{{route('post.update', ['post'=> $post->id])}}">
@csrf
<label  for="title">change title:</label></br>
<input type="text" name="title" value="{{$post->title}}" required></input></br>
<label  for="description">change description:</label></br>
<input type="text" name="description" value="{{$post->description}}" required></input></br>
<label  for="price">change price:</label></br>
<input type="text" name="price" value="{{$post->price}}" required></input></br>

<input type="submit" value="submit">
