update function is not working laravel 6 i am using resource controller

What does your Route look like?

form method="PUT" action= "{{ action('CategoriesController@update',$categories->id) }}

Why your model is Categories and not in the singular form like Category?

Why do you allow to update id?!

In routes

Route::resource('categories', 'CategoriesController');

In controller

public function update(Request $request, Category $category)
{
    // validation without id

    $category->update($request->all());

    return redirect()->route('categories.index');
}

In view

<form action="{{ route('categories.update', ['category' => $category]) }}" method="POST">
     @csrf

     @method('PUT')

    <!-- inputs without id -->
</form>

Read this part of documentation: https://laravel.com/docs/7.x/controllers#resource-controllers

Do you have any errors ? How do you see it dos not work ?

@redroseamit If you change your code to what I recommended to you it will work.

Are you sure you pass the validation ?

madam should i need to change categories model to category ....why ?? i want to update id ...means i created a table inside database which name is categories so there are three column inside category id,name,status...i want when user update something so it will change according to selected id ... example id 1 is selected for update so it will update data of id 1 like name and status...

as @michaloravec say, you need to specify @method('PUT') in your form

Also I suggest you to place a temprary dd('here'); in your controller method to be sure you hit the method

sir i try that not working ...its showing Symfony\Component\Debug\Exception\FatalThrowableError syntax error, unexpected '$categories' (T_VARIABLE)

@redroseamit If your table in the migrations is correct you don't need to send the id, because Laravel will take care of that, updating the id yourself could be dangerous as the wrong id could be sent instead. I also second @thibaultvanc you should add a dd('here'); to debug and make sure you're even getting into the controller update function.

@redroseamit

• did you place the dd('here'); to be sure you hit the good controller method ?
• di you see 'here' at the screen while updating ?

no sir i am confused ...sir can u please guide me what steps should i need follow .. can you please provide code for like i have categories table in database there are three column id name and status ....i want to perform create,update, and delete but only create and delete is working ...i will be more obliged ..

@redroseamit I gave you the correct code.

okay thanks madam let me check this..

exact

madam i made all the changes but now update button is not working.....its not functioning mean neither refreshing page nor updating its stuck continue on update page....

Without your actual code we can't know what are you doing wrong.

@extends('layouts.app')

@section('pageTitle', 'Edit Categories Details')

@section('content')

    <h1 class="display-6">Edit Categories</h1>

    <hr/>
    <!-- if validation in the controller fails, show the errors -->
    @if ($errors->any())
        <div class="alert alert-danger">
            <ul>
                @foreach ($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
    @endif

 

<form action="{{ route('categories.update', ['category' => $category]) }}" method="POST">
     @csrf

     @method('PUT')

    <!-- inputs without id -->
</form>




              <label for="id">ID:</label>
              <input type="text" class="form-control" value="{{$category->id}}" name="id"/>
          </div>
          <div class="form-group">
              <label for="name">Name :</label>
              <input type="text" class="form-control" value="{{$category->name}}" name="name"/>
          </div>
          <div class="form-group">
              <label for="status">status</label>
              <input type="text" class="form-control" value="{{$category->status}}"  name="status"  />
          </div>
         
          <button type="submit" class="btn btn-primary">UPDATE</button>
      </form>
@endsection

Where is the form? Why is there still input where you change id?

Put your code correctly.

On the top and bottom put ```

madam check now i updated code.....

You have to think, when somebody give you an advice.

<form action="{{ route('categories.update', ['category' => $category]) }}" method="POST">
    @csrf

    @method('PUT')

    <div class="form-group">
        <label for="name">Name</label>

        <input type="text" class="form-control" value="{{ $category->name }}" name="name">
    </div>

    <div class="form-group">
        <label for="status">Status</label>

        <input type="text" class="form-control" value="{{ $category->status }}"  name="status">
    </div>

    <button type="submit" class="btn btn-primary">Update</button>
</form>

This was just where you should paste your inputs...

<!-- inputs without id -->
