[moka同学笔记]yii2.0表单的使用

1.创建model   /biaodan.php

 <?php
 /**
  * Created by PhpStorm.
  * User: moka同学
  * Date: 2016/08/05
  * Time: 10:26
  */
 namespace app\models;

 use Yii;
 use yii\base\Model;
 class Biaodan extends Model{
     public $name;
     public $pass;
     public $email;
     public $sex;
     public $edu;
     public $hobby;
     public $info;

     //设置验证规则
     public function rules()
     {
         return [
             [['name','pass','email','sex','edu','hobby','info'],'required'],
             ['email','email','message'=>'这里是邮箱'],
             ['name','string','length'=>[2,10]]
         ];
     }

     //定义表单标签
     public function attributeLabels()
     {
         return [
             'name'=>'名称',
             'email'=>'邮箱',
             'pass'=>'密码',
             'edu'=>'教育',
             'sex'=>'性别',
             'hobby'=>'爱好',
             'info'=>'简介'
         ];
     }
 }
 ?>

注：

自定义标签，用于显示表单标签

rules规则的创建，用于验证表单数据

2.控制器 BiaodanController.php

 <?php
 /**
  * Created by PhpStorm.
  * User: moka同学
  * Date: 2016/08/05
  * Time: 10:23
  */
 namespace app\controllers;

 use app\models\Biaodan;
 use yii\web\Controller;

 class BiaodanController extends Controller{
     public $layout = "home";
     public function actionIndex(){
 //        print_r($_POST);die();
         $model = new Biaodan();
         //如果有表单值就需要通过验证
         if($model->load(\Yii::$app->request->post()) && $model->validate()){
             return $this->render('index-two',['model'=>$model]);
         }else{
             return $this->render('index',['model'=>$model]);
         }
     }
 }
 ?>

注：

\Yii::$app->request->post() 获取表单提交过来的数据

3.视图 index.php

 <?php
 use yii\helpers\Html;
 use yii\widgets\ActiveForm;
 ?>
 <?php $form = ActiveForm::begin(); ?>
 <?=$form->field($model,'name')->textInput(['style'=>'width:200px;'])?>
 <?=$form->field($model,'pass')->passwordInput(['style'=>'width:200px;'])?>
 <?=$form->field($model,'email')->textInput(['style'=>'width:200px;'])?>
 <?=$form->field($model,'sex')->radioList(['1'=>'男','2'=>'女'])?>
 <?=$form->field($model,'edu')->dropDownList(['1'=>'大学','2'=>'中学','3'=>'小学'],['style'=>'width:200px;'])?>
 <?=$form->field($model,'hobby')->checkboxList(['篮球'=>'篮球','排球'=>'排球','乒乓球'=>'乒乓球'])?>
 <?=$form->field($model,'info')->textarea(['rows'=>3,'style'=>'width:400px;'])?>
 <div class="form-group">
     <?=Html::submitButton('提交',['class'=>'btn btn-primary'])?>
 </div>
 <?php $form = ActiveForm::end(); ?>

注：

视图也可以使用gii去生成，但是还是需要更改很多地方

index-two.php (可以忽略)

 <?php
 use yii\helpers\Html;
 ?>
 <ul>
     <li><label><?=$model->name;?></label></li>   <!--//原生写法-->
     <li><label><?=Html::encode($model->pass)?></label></li> <!--//小部件写法-->
 </ul>

注：

表单未完，还有很多bootstrap样式用于表单中

以上~~
