Laravel 表单验证

laravel form validation

创建一个request验证文件

php artisan make:request ArticlesRequest     Request created successfully.

文件内容如下:

app/Http/Requests/ArticlesRequest.php< ?phpnamespace App\Http\Requests;use App\Http\Requests\Request;class ArticlesRequest extends Request{    /**     * Determine if the user is authorized to make this request.     *     * @return bool     */    public function authorize()    {        return true;   //这个是管理权限的,暂时先设置为true,全部权限可用    }    /**     * Get the validation rules that apply to the request.     *     * @return array     */    public function rules()    {        return [            'title'=>'required',  //这里是指定验证的项目,和验证的规则,以数组的方式编写            'content'=>'required'        ];    }}

验证规则参考官网: https://laravel.com/docs/5.2/validation

修改controller的store方法

app/Http/Requests/ArticlesRequest.phpuse App\Http\Requests\ArticlesRequest;//    public function store(Request $requests){    public function store(ArticlesRequest $requests){ //这里传入的是刚才创建的ArticlesRequest的实例        Articles::create($requests->all());        return redirect('/articles');    }

因为现在增加了验证,所以对store方法的进入的请求request都会进行过滤,但是直接过滤就不知道成功和失败了,所以要额外增加一个提示

resources/views/articles/create.blade.php@extends('layout.app')@section('content')    <h1 id="创建文章">创建文章</h1>    {!! Form::open(['url'=>'/articles/store']) !!}            <!--- Title Field --->    <div class="form-group">        {!! Form::label('title', 'Title:') !!}        {!! Form::text('title', null, ['class' => 'form-control']) !!}    </div>    <!--- Content Field --->    <div class="form-group">        {!! Form::label('content', 'Content:') !!}        {!! Form::textarea('content', null, ['class' => 'form-control']) !!}    </div>    <!---  Field --->    <div class="form-group">        {!! Form::label('publish_at', 'publish_at:') !!}        {!! Form::date('publish_at', date('Y-m-d'), ['class' => 'form-control']) !!}    </div>    {!! Form::submit('发表文章',['class'=>'btn btn-primary form-control']) !!}    {!! Form::close() !!}    @if($errors->any())  //增加这里,$errors变量是laravel提供的,就是捕获这些出错而保存的变量,是一个数组        <ul class="list-group">            @foreach($errors->all() as $error) //所以需要循环变量数组,获取最终报错信息                <li class="list-group-item list-group-item-danger">{{$error}}</li>            @endforeach        </ul>    @endif@stop

需要注意的是,在laravel 5.2里面,$errors变量需要在中间件web里面才会存在,如果不是的话,laravel会报错,Undefined variable: errors。

正常情况下,触发验证规则的报错弹出提示会在网页中显示,例如

The title field is required.The content field is required.

重写报错提示信息,例如改成中文提示,需要在request文件里面重写messages方法,文件内默认没有,所以我们需要添加

app/Http/Requests/ArticlesRequest.php    public function messages()    {        return [            'title.required' => '这个标题是必须的!', //例如这样就会匹配标题required的规则,然后触发你的提示            'body.required'  => '这个身体是必须的!',        ];    }

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
