How to do update dropdown & how to make selected value for validation purpose in laravel?

Question

In my view method, my selected dropdown like this. My problem are:-

1. How do I retrieve data from a database if I'm using the dropdown field? (Update Method)

2. How do I want to make the dropdown selected? (Validation & Show Method)

                         <div>
                            <x-label for="type" :value="__('Choose pizza type:')" />
                                <select name="type" id="type" class="form-control">
                                    <option selected disabled>Please choose</option>
                                    <option value="Chicken" {{ $value->type =="Chicken" ? 'selected' : '' }}>Chicken</option>
                                    <option value="Seafood" {{ $value->type =="Seafood" ? 'selected' : '' }}>Seafood</option>
                                    <option value="Beef" {{ $value->type =="Beef" ? 'selected' : '' }}>Beef</option>
                                    <option value="Prawn" {{ $value->type =="Prawn" ? 'selected' : '' }}>Prawn</option>
                                    <option value="Tuna" {{ $value->type =="Tuna" ? 'selected' : '' }}>Tuna</option>
                                </select>
                                <span style="color:red">@error('type'){{ $message }} @enderror</span>
                        </div>
   

I got an error as shown below:-

Answer 1

Here are my migration tables:-

public function up()
{
    Schema::create('pizzas', function (Blueprint $table) {
        $table->id();
        $table->timestamp('updated_at')->useCurrent();
        $table->timestamp('created_at')->useCurrent();
        $table->string('name');
        $table->string('type');
        $table->string('base');
    });
}

To send a drop-down variable, you must send it as an array

• HTML Code:

<div>
                         <x-label for="type" :value="__('Choose pizza type:')" />
                             <select name="type[]" id="type" class="form-control">
                                 <option selected disabled>Please choose</option>
                                 <option value="Chicken" {{ $value->type =="Chicken" ? 'selected' : '' }}>Chicken</option>
                                 <option value="Seafood" {{ $value->type =="Seafood" ? 'selected' : '' }}>Seafood</option>
                                 <option value="Beef" {{ $value->type =="Beef" ? 'selected' : '' }}>Beef</option>
                                 <option value="Prawn" {{ $value->type =="Prawn" ? 'selected' : '' }}>Prawn</option>
                                 <option value="Tuna" {{ $value->type =="Tuna" ? 'selected' : '' }}>Tuna</option>
                             </select>
                             <span style="color:red">@error('type'){{ $message }} @enderror</span>
                     </div>

• validation(in controller):

$this->validate($request, [
            'type' => 'required|...'
        ]);

                                    <option value="Chicken"{{ $Info->type =="Chicken" ? 'selected':''}}>Chicken</option>

                                    <option value="Beef"{{ $Info->type =="Beef" ? 'selected':''}}>Beef</option>

                        </div>
