<?php echo CHtml::checkBoxList('checkbox_list_name', '', array(
'Users' => 'All Users',
'Claim' => 'Claim Request',
'Business' => 'Add Business'
), array('id'=>'checkbox-list-id','class'=>'checkboxlist', 'required')). "<br>"; ?>

我已经编写了以下代码来制作一个复选框,我想把它变成一个像Html中那样的必填字段。

您好您可以添加javascript function以阻止表单提交,但如果禁用了javascript则会失败,因此您应同时使用javascriptserver side validation

**Server Side validation**

1)在variable(虚拟变量)

中定义model

Model.php

class Model extends CActiveRecord
{
    /**
     * @return string the associated database table name
     */          
        public $checkbox_list_name;

2)在模型中的安全规则中定义

public function rules()
    {
 array('checkbox_list_name','safe'),
}

3)在你的form.php中

<?php echo $form->checkBoxList($model,'checkbox_list_name', array(
'Users' => 'All Users',
'Claim' => 'Claim Request',
'Business' => 'Add Business'
), array('id'=>'checkbox-list-id','class'=>'checkboxlist', 'required')). "<br>"; ?>

    <?php echo $form->error($model,'checkbox_list_name'); ?>

4)在YourController.php中

检查是否选中了复选框

public function actionYouraction() {
        $model = new Model();
        $this->performAjaxValidation($model);

        if (isset($_POST['Model'])) {

            if($_POST['Model']['checkbox_list_name'] == ''){
                 $model->addError('checkbox_list_name', 'Select At least one!!!'); // this will through error if checkbox is not selected                   
            }else{

            $model->attributes = $_POST['Model'];
            $model->save();
        }
        $this->render('view', array(
            'model' => $model,
        ));
    }

Javascript方法 - 这会计算文本框的长度,如果没有选择至少一个

,则返回false
<script type="text/javascript">
    $('#user-form').submit(function() {// relace user-form id with your CActiveRecord form id
   if(!($('input[type="checkbox"]:checked').length)) {
    alert("Select at least one!!!");  
    return false;
}
  return true;
});

    </script>
