laravel5表单验证

学习laravel框架有一段时间了，觉得它自带的表单验证特别好用，和大家分享分享

对于一些验证规则手册上都有，相信大家看了就会，我简单的说下怎么使用自定义正则验证：

验证手机号：'tel' => array('regex:/^1(3|4|5|7|8)d{9}$/'),  直接加入到validate里验证即可

还有一点就是在验证时，验证出错后怎么保持原来输入的信息，下面贴上代码，更容易理解：

1、控制器

//验证表单
    public function postCheck(Request $req)
    {    
    　　
        $this->validate($req, 
         [
            'email' => 'bail|required|email|max:25|unique:user,email',
            'pwd_confirmation' => 'required|alpha_dash|between:6,20',
            'pwd'=>'required|confirmed',
            'explain'=>'required',
            'checkbox'=>'accepted',
        ],
        [    'email.required' =>'We need to know your e-mail address!',   //自定义错误信息
            'email.email' => 'Please fill in the correct email address.!',
            'email.max' => 'Mailbox length maximum 25 characters!',
            'email.unique' => 'The mailbox is too fire, has been registered!',

            'pwd_confirmation.required' =>'Please enter your password!',
            'pwd_confirmation.between' => 'Password must be 6 to 20 characters!',

            'pwd.required' => 'Please Confirm your password!',
            'pwd.confirmed' => 'Confirm password error!',

            'explain.required' => 'Please fill in the details!',
            
            'checkbox.accepted' => 'Please agree to the registration agreement!',

        ]);
              //验证通过后数据入库
    
        $date = $req->all();  //接到的参数
        $res = $this->add($date);
}
    

2、视图（只写了一个，其他的复制）

                <div class="form-group">
                    <input type="email" class="form-control" placeholder="请输入邮箱" required="" id="email" name="email" value="{{old('email')}}">
                </div>
　　　　　　　　　　//错误信息显示
            @if($errors->has('email'))
                <div class="alert alert-danger">
                    @foreach($errors->get('email') as $error)
                        {{$error}}
                    @endforeach
                </div>
            @endif
