yii2.0使用ActiveForm

Controller控制器层代码

 <?php

 namespace frontend\controllers;

 use frontend\models\UserForm;
 class UserController extends \yii\web\Controller
 {
     public function actionIndex()
     {
         $model = new UserForm;
         if ($model->load(\Yii::$app->request->post()) && $model->validate())
         {
             echo "通过";
         }

         return $this->render('index',[
             "model" => $model,
         ]);
     }

 }

VIEWS视图层代码

 <?php
 use yii\helpers\Html;
 use yii\widgets\ActiveForm;

 ?>

 <h1>YII2.0使用ActiveForm</h1>

 <?php $form = ActiveForm::begin([
     'action' => ['log/login'], //提交地址(*可省略*)
     'method'=>'post',    //提交方法(*可省略默认POST*)
     'id' => 'login-form', //设置ID属性
     'options' => [
             'class' => 'form-horizontal', //设置class属性
             'enctype' => 'multipart/form-data' //文件上传时添加该编码
     ],
     'fieldConfig' => [
             'template' => '<div class="form-group"><center><label class="col-md-2 control-label" for="type-name-field">{label}</label></center><div class="col-md-8 controls">{input}{error}</div></div>'
     ],  //设置模板的样式
 ]); ?>

     <!--文本框 (*验证长度可在这里写 maxlength 这样就不用再 model 里面写了 *)-->
     <?= $form->field($model, 'username',['template'=>'<div class="form-group"><div class="col-md-8 controls">{label}{input}{error}</div></div>'])->textInput(['maxlength' => 20,"style"=>"width:200px; height:30px;"]) ?>

     <!--密码框 (*不使用他的lable只需要用false把他禁止, 然后你可以自己写*)-->
     <h4>密码</h4><?= $form->field($model, 'pwd')->label(false)->passwordInput(['maxlength' => 20,"style"=>"width:200px; height:30px;","placeholder"=>"请输入您的密码"]) ?>

     <?= $form->field($model, 're_pwd')->passwordInput(['maxlength' => 20,"style"=>"width:200px; height:30px;","placeholder"=>"请输入您的密码"]) ?>

     <!--单选按钮(*设置默认选中*)-->
     <?php $model->sex=1; echo $form->field($model, 'sex')->radioList(['1'=>'男','0'=>'女']) ?>

     <!--验证邮箱-->
     <?= $form->field($model, 'email')->textInput() ?>

     <!--下拉框的默认选中使用 prompt 设置 -->
     <?= $form->field($model, 'school')->dropDownList(['1'=>'大学','2'=>'高中','3'=>'初中'], ['prompt'=>'请选择','style'=>'width:120px']) ?>

     <!--文件上传-->
     <?= $form->field($model, 'photo')->fileInput() ?>

     <!--复选框 -->
     <?= $form->field($model, 'hobby')->checkboxList(['0'=>'篮球','1'=>'足球','2'=>'羽毛球','3'=>'乒乓球']) ?>

     <!--文本域-->
     <?= $form->field($model, 'remark')->textarea(['rows'=>3]) ?>

     <!--隐藏域-->
     <?= $form->field($model, 'userid')->hiddenInput(['value'=>3])->label(false); ?>

     <?= Html::submitButton('提交', ['class'=>'btn btn-primary','name' =>'submit-button']) ?>

     <?= Html::resetButton('重置', ['class'=>'btn btn-primary','name' =>'submit-button']) ?>

 <?php ActiveForm::end(); ?>

MODELS层表单验证

      */
     public function rules()
     {
         return [
             //验证不能为空
             [['username', 'pwd', 'email', 'hobby'], 'required' ,"message"=>"{attribute}不能为空"],

             [['remark'], 'string', 'max' => 200],


         ];
     }

     /**
      * @inheritdoc
      */
     public function attributeLabels()
     {
         return [
             'user_id' => '自增ID',
