laravel验证规则

就拿laravel的登入验证来举例：

1.进入login控制器，

use AuthenticatesUsers;从这里点进去
找到验证规则

//验证
protected function validateLogin(Request $request)
{
    $request->validate([
        $this->username() => ‘required|string‘,
        ‘password‘ => ‘required|string‘,
    ]);
}
放入login控制器中
2.进入laravel5.7文档验证那一节找到

@if ($errors->any())
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
放入login模板中。如用其他UI可自行更改样式
例如amazeui

@if ($errors->any())
    <div class="am-alert am-alert-danger" data-am-alert>
        <button type="button" class="am-close">x</button>
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
设定个JS定时消失

$(function () {
    var action=(function(){
        $(‘.am-close‘).click()
    })
    var id=setInterval(action,2000)
})

3.安装laravel语言包

跑命令composer require "overtrue/laravel-lang:~3.0"

php artisan lang:publish zh-CN


5.ok！
