调用$this->validate对表单验证时出错

yuzhibiao · 9年前

    public function store(Request $request)
    {
        //验证规则
        $this->validate($request, [
            'title'        => 'required|min:3',
            'content'      => 'required',
            'published_at' => 'required',
        ]);

        $input = $request::all();
        //下面增加两行，顺便看看$request::get的使用
        $input['intro'] = mb_substr($request::get('content'), 0, 64);
        //$input['published_at'] = Carbon::now();
        Article::create($input);

        return redirect('/articles');
    }

具体代码如上，以为为提示错误：
ErrorException in ValidatesRequests.php line 30:
