YII2.0使用ActiveForm表单（转）

Controller控制器层代码

<?php

namespace frontendcontrollers;

use frontendmodelsUserForm;
class UserController extends yiiwebController
{
    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 yiihelpersHtml;
use yiiwidgetsActiveForm;

?>

<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',['inputOptions' => ['placeholder'=>'请输入用户名','class' => 'ipt'],'template'=>'<div class="form-group"><div class="col-md-8 controls">{label}{input}{error}</div></div>'])->textInput(['maxlength' => 20,"style"=>"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"=>"200px; height:30px;","placeholder"=>"请输入您的密码"]) ?>

    <?= $form->field($model, 're_pwd')->passwordInput(['maxlength' => 20,"style"=>"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'=>'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']) ?>
