laravel form

1. Composer 安装

composer require illuminate/html

 需要php-xml扩展支持

2. 添加 providers

修改 config/app.php 文件, 在 providers 数组里面添加:

'IlluminateHtmlHtmlServiceProvider'

3. 添加 aliases

'Form'  => 'IlluminateHtmlFormFacade',
'HTML'  => 'IlluminateHtmlHtmlFacade'

表单token

<input type="hidden" name="_token" value="{{ csrf_token() }}"/>

表单 edit 修改

    <form action="/a/{{ $a->id }}" method="post">
        <input type="hidden" name="_method" value="put"/>
        <input type="hidden" name="_token" value="{{ csrf_token()  }}"/>
        ............

    </form>

 表单错误提示

@if( $errors->any())
    <ul class="list-group">
        @foreach($errors->all() as $error)
            <li class="list-group-item list-group-item-danger">{{ $error }}</li>
            @endforeach
    </ul>
@endif

 路由模块绑定 app/Providers/RouteServiceProvider.php

    public function boot(Router $router)
    {
        //

        parent::boot($router);

        $router->model('a','AppArticle');
    }

 多选框

        <select name='tags[]' multiple="multiple">
        @foreach($tags as $id => $tag)
            <option  value="{{$id}}">{{ $tag }}</option>
            @endforeach
        </select>
