yii 2.0中表单小部件的使用方法示例

前言

本文主要介绍的是关于yii 2.0中表单小部件使用的相关内容，分享出来供大家参考学习，下面来看看详细的介绍：

使用方法

首先创建model层，因为要使用表单小部件 所以要加载相应的组件，这里需要的组件有yii/widgets/ActiveForm yii/helpers/Html

接下来在model定义的class里 写方法，首先我们要定义需要使用表单小部件的name值

不多说上代码

<?php/*** Created by PhpStorm.* User: jinlei* Date: 2017/5/10* Time: 9:35*/namespace frontend/models;use yii/base/Model;use yii/widgets/ActiveForm;use yii/helpers/Html;class Form extends Model{public $name;public $pwd;public $sex;public $hobby;public $age;public function rules(){return[];}public function attributeLabels(){return[‘name'=>'用户名',‘pwd'=>'密码',‘sex'=>'性别',‘hobby'=>'爱好',‘age'=>'年龄'];}static public function dataarr($data){$arr = array();foreach($data as $key=>$value){$arr[$value[‘kid']] = $value[‘kname'];}return $arr;}}

在这个model里 有将英文表头转换中文的方法 attributuLabels

还有 我们处理单选多选还有下拉框值得方式 dataarr

接下来 我 们需要创建controller

<?php/*** Created by PhpStorm.* User: jinlei* Date: 2017/5/10* Time: 9:39*/namespace frontend/controllers;use yii/web/Controller;use yii;use db;use frontend/models/Form;class LoginController extends Controller{public function actionIndex(){$sql = ‘select kid,kname from exam_tiku';$data = yii::$app->db->createCommand($sql)->queryAll();$arr = Form::dataarr($data);//var_dump($arr);die;$model = new Form();return $this->render(‘index',[‘model'=>$model,'data'=>$arr]);}public function actionAdd(){$data = Yii::$app->request->post();echo $name = $data[‘Form'][‘name'];}}

然后就是在我门的view层 展示出来

<?php/*** Created by PhpStorm.* User: jinlei* Date: 2017/5/10* Time: 9:41*/use yii/helpers/Html;use yii/widgets/ActiveForm;$form = ActiveForm::begin([‘id' => ‘login-form',‘options' => [‘class' => ‘form-horizontal'],‘action'=>'?r=login/add',‘method'=>'post',]) ?><?= $form->field($model, ‘name') ?><?= $form->field($model, ‘pwd')->passwordInput() ?><?= $form->field($model, ‘sex')->radioList([‘0'=>'男','1'=>'女']) ?><?= $form->field($model, ‘hobby')->checkboxList([‘basketball'=>'篮球','baseball'=>'棒球','swim'=>'游泳']) ?><?= $form->field($model, ‘age')->dropDownList($data) ?><div class=”form-group”><div class=”col-lg-offset-1 col-lg-11″><?= Html::submitButton(‘Login', [‘class' => ‘btn btn-primary']) ?></div></div><?php ActiveForm::end() ?>
