		视图层

<?php

use yiihelpersHtml;
use yiiwidgetsActiveForm;
use yiicaptchaCaptcha;
use frontendmodelsWorkyearModel;

/* @var $this yiiwebView */
/* @var $model frontendmodelsFormsModel */
/* @var $form ActiveForm */
?>
<div class="forms-index">

    <?php $form = ActiveForm::begin(['id'=>'sign-form', 'options'=>['action'=>'forms/index', 'method'=>'post', 'enctype'=>'multipart/form-data']]);  ?>

        
        <?= $form->field($model, 'username',['enableAjaxValidation' => true])->textInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'password')->passwordInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'repassword')->passwordInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'sex')->radioList(['男'=>'男','女'=>'女']) ?>
        <?= $form->field($model, 'age')->textInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'phone',['enableAjaxValidation' => true])->textInput(['maxlength' => true]) ?>
	<?= $form->field($model,'workyear')->dropdownList(WorkyearModel::find()->select(['workyear', 'w_id'])->
      indexBy('w_id')->column(),['prompt'=>'请选择工作经验']);?> <?= $form->field($model, 'email',['enableAjaxValidation' => true]) ?> <?= $form->field($model, 'hobby')->checkboxList(['唱歌'=>'唱歌','跳舞'=>'跳舞','看电影'=>'看电影']) ?> <?= $form->field($model, 'selfdesc')->textInput(['maxlength' => true]) ?> <?= $form->field($model, 'userimg')->fileInput() ?> <?= $form->field($model, 'captcha')->widget(Captcha::className(), ['captchaAction'=>'forms/captcha', 'template' => '<div class="row"><div class="col-lg-3">{image}</div><div class="col-lg-6">{input}</div></div>', ]) ?> <div class="form-group"> <?= Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?> </div> <?php ActiveForm::end(); ?> </div><!-- forms-index --> 解析: Filter: 过滤,'filter'=>'trim',表示去空格 Required:必须的,表示不能为空 Match: 匹配正则,需要和pattern一起使用,定义正则表达式,'pattern'=>'/^w{6,20}$/', Unique:验证数据唯一性,在注册时用到的比较多,这里需要注意的是,在rules规则里面定义的唯一性验证,只有在服务器端才能验证,
如果想要在表单页面显示,需要开启”enableAjaxValidation”=>ture; 例如: <?php $form = ActiveForm::begin([ 'id'=>'sign-form', //'enableAjaxValidation' => true,//启用ajax验证,将属性值发送到服务器端进行验证并返回结果,默认为false 'enableClientValidation' => true,//启用客户端验证,默认值为true,关闭后表单无js验证 'options'=>['action'=>'usermessage/signform', 'method'=>'post', 'enctype'=>'multipart/form-data']]); ?> 这里需要注意的是,在这里启用的话,ajax验证是作用于所有的属性的,所以,还有另一种开启方式,在某一个field里面开启:
<?= $form->field($model, 'username', ['enableAjaxValidation'=>true])->textInput() ?>,这样就单独作用于username属性了。 要想实现表单ajax验证唯一性,后台还要一个ajax判断: $model->load(Yii::$app->request->post()); if (Yii::$app->request->isAjax) { Yii::$app->response->format = yiiwebResponse::FORMAT_JSON; return yiiootstrapActiveForm::validate($model); } 在有数据提交时,最好先执行$model->load(Yii::$app->request->post()); 操作,不要做多余的处理,然后判断ajax,否则ajax验证的时候可能会报错500。如果有验证码, 这里就会有另一个问题:return yiiootstrapActiveForm::validate($model);这个验证的是所有的属性,而验证码执行validate后就会重新生成,
那么在表单提交时我们进行数据有效性验证时就会报错, 解决方式:yiiootstrapActiveForm::validate()这个方法其实是有两个参数的,$model,$attributes,我们可以指定ajax验证某一些特定的属性,
写法是:yiiootstrapActiveForm::validate($model, ['username', 'email', 'phone']); 这样ajax验证时就只验证username,email,phone这三个字段了,不会影响验证码。 Number:数字验证,加上'integerOnly'=>true,表示只能是整数,max,min分别表示最大最小值,tooBig和tooSmall分别是超过最大值和低于最小值时的错误提示信息 Compare:比较,用于两个属性之间的比较,'compareAttribute'=>'password',表示与password比较 In:和range连用,定义范围,表示属性值必须在这个范围内,通常用于验证某些固定值 Email:邮箱验证 File:文件验证 extensions可以定义上传文件的类型 Captcha:验证码验证,需要定义生成验证码的方法,'captchaAction'=>'usermessage/captcha',usermessage表示控制器名,captcha表示方法名 可以在控制器层定义一个actions方法添加captcha方法: /** * 生成验证码的方法 */ public function actions() { parent::actions(); return [ 'captcha' => [ 'class' => 'yiicaptchaCaptchaAction', //'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null, 'maxLength' => 3, 'minLength' => 3 ], ]; } 每一个验证都可以添加应用场景:’on’=>’register’; 在控制器层实例化模型层 $model = new Usermessage(); $model->setScenario('register'); 定义使用应用场景为register 在模型层需要定义场景作用的对象 /** * 定义验证场景 */ public function scenarios() { return [ 'register' => ['username', 'password', 'repassword', 'age', 'sex', 'phone','email'], 'login' => ['username', 'password','age', 'sex', 'phone','email'], ]; } 然后在对应的验证规则后面限定应用场景’on’=>’register’; 当表单验证时,为在作用场景以内的参数可以不受验证规则的限制 添加入库:复选框因提交过来后是一个数组,所以在执行save()前需要将复选框的值处理成字符串
