本文实例讲述了yii用户注册表单验证实现方法。分享给大家供大家参考,具体如下:
视图层:register.php
<?php //使用小物件生成form元素 $form=$this->beginwidget('cactiveform'); ?> <!--用户名--> <?php echo $form->labelex($model,'username');?> <?php echo $form->textfield($model,'username');?> <?php echo $form->error($model,'username');?> <br> <!--密码--> <?php echo $form->labelex($model,'password');?> <?php echo $form->passwordfield($model,'password');?> <?php echo $form->error($model,'password');?> <br> <!--确认密码--> <?php echo $form->labelex($model,'password2');?> <?php echo $form->passwordfield($model,'password2');?> <?php echo $form->error($model,'password2');?> <br> <!--邮箱--> <?php echo $form->labelex($model,'email');?> <?php echo $form->textfield($model,'email');?> <?php echo $form->error($model,'email');?> <br> <!--性别--> <?php echo $form->labelex($model,'sex');?> <?php echo $form->radiobuttonlist($model,'sex',array(1=>'男',2=>'女'),array("separator"=>" "));?> <br> <!--年级--> <?php echo $form->labelex($model,'grade');?> <?php echo $form->dropdownlist($model,'grade',array(0=>"--请选择--",1=>"2010级",2=>"2011级",3=>"2012级"));?> <?php echo $form->error($model,'grade');?> <br> <?php echo $form->labelex($model,'hobby');?> <?php echo $form->checkboxlist($model,'hobby',array(1=>"篮球",2=>"足球",3=>"排球"),array("separator"=>" "));?> <?php echo $form->error($model,'hobby');?> <!--提交--> <?php echo chtml::submitbutton('提交');?> <?php $this->endwidget(); ?>
model层的代码如下:user.php
<?php /* * to change this template, choose tools | templates * and open the template in the editor. */ class user extends cactiverecord{ //创建一个模型的对象 静态 public $password2;//非数据库的字段,但是在view中需要用到 public static function model($classname = __class__) { return parent::model($classname); } //返回当前数据表的名字 public function tablename() { //parent::tablename(); return '{{user}}';//这样写可以省略前缀 } //设置标签的显示名字 public function attributelabels() { return array( "username"=>"姓名", "password"=>"密码", "password2"=>"确认密码", "email"=>"邮箱", "sex"=>"性别", "grade"=>"年级", "hobby"=>"爱好", ); } //验证表单域 public function rules() { return array( array("username","required","message"=>"用户名不能为空"), array("password","required","message"=>"密码不能为空"), //验证密码和确认密码 array("password2","compare","compareattribute"=>"password","message"=>"两次密码不一致"), //验证邮箱 array("email","email","allowempty"=>false,"message"=>"邮箱格式不正确"), //验证年级 array("grade","in","range"=>array(1,2,3),"message"=>"请选择年级"), //验证爱好,使用自定义规则 array("hobby","checkhobby"), ); } //验证爱好 function checkhobby(){ $this->hobby; $len= strlen($this->hobby); if($len<3){ $this->adderror("hobby","爱好至少为2个以上"); } } } ?>
control层的代码如下:
//信息添加 添加显示页面和添加处理使用同一个方法 public function actionadd(){ $user=new user(); if(isset($_post['user'])){ // foreach ($_post['user'] as $k =>$v){ // $user->$k=$v; // } if(is_array($_post['user']['hobby'])) $_post['user']['hobby']= implode(",", $_post['user']['hobby']); //print_r($_post['user']); $user->attributes=$_post['user']; if($user->save()){ echo 'success'; }else{ echo 'error'; } } $this->renderpartial("new",array("model"=>$user)); }
其中,表单的自动验证,在model层实现,表单元素的名称与数据库中的字段名字一致,可设置错误信息进行提示。
希望本文所述对大家基于yii框架的php程序设计有所帮助。
