YII2.0使用ActiveForm表单（转）

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
]); ?>
<?= $form->field($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"=>"width:200px; height:30px;"]) ?>
<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"]) ?>
<?php $model->sex=1; echo $form->field($model, 'sex')->radioList(['1'=>'男','0'=>'女']) ?>
<?= $form->field($model, 'email')->textInput() ?>
<?= $form->field($model, 'school')->dropDownList(['1'=>'大学','2'=>'高中','3'=>'初中'], ['prompt'=>'请选择','style'=>'width:120px']) ?>
<?= $form->field($model, 'photo')->fileInput() ?>
<?= $form->field($model, 'hobby')->checkboxList(['0'=>'篮球','1'=>'足球','2'=>'羽毛球','3'=>'乒乓球']) ?>
<?= $form->field($model, 'remark')->textarea(['rows'=>3]) ?>
<?= $form->field($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

<?php
namespace frontend\models;
use Yii;
class UserForm extends \yii\db\ActiveRecord
{
/**
*@param参数
*/
public $username;
public $pwd;
public $re_pwd;
public $email;
public $bobby;
public $remark;
public $photo;
public $school;
public $info;
/**
* @inheritdoc
*/
public static function tableName()
{
return '{{%user}}';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
//验证不能为空
[['username', 'pwd', 'email', 'hobby'], 'required' ,"message"=>"{attribute}不能为空"],
//验证用户唯一
['username', 'unique', 'targetClass' => '\frontend\models\User', 'message' => '用户名已存在.'],
//验证密码不一致
['re_pwd', 'compare', 'compareAttribute' => 'pwd', 'message' => '两次密码不一致'],
//验证字符串长度
[['username'],"string", "max"=>"10", "min"=>"5", "tooLong"=>"{attribute}不能大于10个字符", "tooShort"=>"{attribute}不能小于5个字符"],
//验证文件上传的格式
['photo','file',
'extensions'=>['jpg','png','gif'],'wrongExtension'=>'只能上传{extensions}类型文件！',
'maxSize'=>1024*1024*2, 'tooBig'=>'文件上传过大！',
'skipOnEmpty'=>false,'uploadRequired'=>'请上传文件！',
'message'=>'上传失败！'
]
//采用rules 规则验证
['email', 'email',"message"=>"{attribute}格式错误"],
//方法2:
//正则验证 ['tel','match','pattern'=>'/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})?$/','message'=>"{attribute}邮箱输入有误."],
[['remark'], 'string', 'max' => 200],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'user_id' => '自增ID',
'username' => '用户名',
'pwd' => '密码',
're_pwd' => '请再次输入密码',
'sex' => '性别',
'photo' => '头像',
'email' => '邮箱',
'hobby' => '爱好',
'school' => '学校',
'remark' => '备注信息',
];
}
}
