<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class 〇〇Request 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 [
バリデーションのロジックをかく
];
}
}
そしてコントローラーでフォームリクエストを読み込むだけです。
use App\Http\Requests\〇〇Request;
class 〇〇Controller extends Controller
{
/**
* 登録処理
*/
public function store(〇〇Request $request)
{
return redirect()->route('index');
}
/**

*/
public function update(〇〇Request $request, $id)
{
return redirect()->route('.index');
}
}
<?php

use Illuminate\Foundation\Http\FormRequest;
class BookRequest extends FormRequest
{
/**

public function authorize()
{
return true;
}
/**

public function rules()
{
return [
//

}
}
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class BookRequest extends FormRequest
{
/**

*/
public function authorize()

return true;

public function rules()

return [
'ビューのnameの属性名' => 'バリデーションの種類',
];
}
}
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class BookRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**

*/
public function rules()
{
return [
'book_name' => 'required',
];
}
public function messages()
{
return [
'book_name.required' => '本の名称は必ず入力してください。',
];
}
}
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class BookRequest 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 [
'book_name' => 'required|max:10',
'book_number' => 'required|numeric|digits:2|between:1,90',
];
}
public function messages()
{
return [
'book_name.required' => '本の名称は必ず入力してください。',
'book_name.max' => '本の名称は10文字以内で入力してください。',
'book_number.required' => '本のNo.は必ず入力してください',
'book_number.numeric' => '本のNo.は数値で入力してください。',
'book_number.digits' => '2桁以内で入力してください。',
'book_number.between' => '1〜90の間で入力してください',
];
}
}
これでフォームリクエストを用いて複数のバリデーションは実装できます。
最後に＋αでこんな書き方もあるよ〜といのも紹介しておきます。
【実務編】フォームリクエストをさらにすっきり書くなら
私が実務で実際にフォームリクエストを書いている方法はさらにシンプルです。
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class BookRequest 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()
{
$validate = [];
$validate += [
'book_name' => [
'required',
'max:10',
],
'book_number' => [
'required',
'numeric',
'digits:2',
'between:1,90'
],
];
return $validate;
}
}
<?php
return [
