[Day 48] 留言板後台及前台(四) - 處理留言板內容

留言板後台及前台

我們之前的web.php沒有考慮到編輯留言板的部分,
所以我們在留言板的後面再加上一列

//編輯留言板
Route::post('/board', 'HomeController@boardProcess');

然後加上 app/Http/Controllers/HomeController.php 加上 boardProcess這個函式

public function boardProcess($user_id)
{
    $this->page = 'user';
    $name = 'board';

    $userData = User::where('id', $user_id)->first();

    if(!$userData)
        return redirect('/');

    $boardList = Board::where('board_id', $userData->id)->orderby('created_at', 'desc')->get();
    //接收輸入資料
    $input = request()->all();

    //驗證規則
    $rules = [
        //內容
        'content' => [
            'required',
            'max:400'
        ],
        //電子郵件
        'email' => [
            'required',
            'max:45'
        ],
    ];

    $User = $this->GetUserData();

    $binding = [
        'title' => ShareData::TITLE,
        'page' => $this->page,
        'name' => $name,
        'User' => $this->GetUserData(),
        'userData' => $userData,
        'boardList' => $boardList,
    ];

    //驗證資料
    $validator = Validator::make($input, $rules);

    //未登入的處理
    if(!$User)
    {
        //自定義錯誤訊息
        $validator->errors()->add('user', '請先登入才能留言');

        return view('blog.board', $binding)
            ->withErrors($validator)
            ->withInput($input);
    }

    if($validator->fails())
    {
        return view('blog.board', $binding)
            ->withErrors($validator)
            ->withInput($input);
    }
}

在這裡我們要做一些說明,
因為有可能會出現錯誤,
所以留言板的資料還是要抓,
然後這裡多一個判斷登入的部分,

$User = $this->GetUserData();
if(!$User)

如果還沒有登入就會做處理,
並且我們自己加入錯誤訊息

$validator->errors()->add('user', '請先登入才能留言');

如果發生錯誤,
我們還會把之前使用者編輯的內容帶出來,

return view('blog.board', $binding)
    ->withErrors($validator)
    ->withInput($input);

然後甚麼都不輸入並按下送出,
就會看到以下畫面

目前我們只處理了錯誤的部分,
至於新增留言的部份等明天再說.
因為有修改了SCSS檔案,
所以附上SCSS檔案內容
