Details: I have form with two buttons and I made validation how to skip validation when click on (back-button)?

the code in the view page:

<form method="POST" action="{{route("movies.store")}}" class="mt-5 w-50 m-auto">
    @csrf
  <div class="mb-3">
    <label class="form-label">Movie Name</label>
    <input type="text" name="movie_name" class="form-control">
    @error('movie_name')
    <span class="error">{{$message}}</span>
    @enderror
  </div>
  <div class="mb-3">
    <label class="form-label">Movie Descrption</label>
    <input type="text" name="movie_description" class="form-control">

    @error('movie_gener')
    <span class="error">{{$message}}</span>
    @enderror
  </div>
  <button type="submit" name="action" value="back" class="btn btn-warning me-3">Back</button>
  <button type="submit" name="action" value="add" class="btn btn-primary">Add</button>
</form>

the code in the controller file:

public function store(MoviesFormRequest $request)
{

    switch ($request->input('action')) {
        case 'back':
            return redirect()->route("movies.index");

        case 'add':
            $data = $request->validated();

            Movie::create($data);

            return redirect()->route("movies.index");
    }
}

If you just want to solve the problem by implementing back button instead of using button tag use anchor tag as follows

<a href="{{rout('movies.index')}}" class="btn btn-warning me-3">Back</a>

And remove the switch statement and just do as follows:

public function store(MoviesFormRequest $request)
{
    Movie::create($request->all());

    return redirect()->route("movies.index");
}

Inside your MoviesFormRequest class do all the validations like :

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class MoviesFormRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
      */
    public function rules()
    {
        return [
            'movie_name' => 'required',
            'movie_description' => 'required',
            'movie_gener' => 'required',
        ];
    }
}

This will work for you just customize the anchor tag to look good. Hope this solve your problem.

The validation happens in your custom request (MoviesFormRequest) before the code in the controller method is executed.

So in order to skip validation given a specific request input, you have to make the it part of the switch block

use Illuminate\Http\Request;

// use the base request here (no validation at this point)
public function store(Request $request)
{

    switch ($request->input('action')) {
        case 'back':
            return redirect()->route("movies.index");

        case 'add':
            // in our case block we can validate
            $this->validate($request, [ 
                'title' => ['required'],
                //... your rules here
            ]);

            $data = $this->validated();

            Movie::create($data);

            return redirect()->route("movies.index");
    }
}
