<?php

namespace AppHttpRequests;

use IlluminateFoundationHttpFormRequest;
use IlluminateSupportFacadesAuth;

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

    /**

     *
     * @return array<string, mixed>
     */

    //  validasi data
    public function rules()
    {
        return [
            'nama' => 'required|string|max:255',
            'type_id' => 'required|integer|exists.types,'.$this->id,
            'brand_id' => 'required|integer|exists.brands,'.$this->id,
            'photos' => 'nullable|array',
            'photos.*' => 'nulable|image|mimes:jpeg,png,jpg|max:2048',
            'features' => 'nullable|string',
            'price' => 'required|numeric',
            'star' => 'nullable|numeric',
            'review' => 'nullable|numeric'
        ];
    }
}
