YII高级搜索页面

Question

我提前搜索页面，所有字段都声明为搜索变量。 我在会话中持有所有变量。

我想知道的是点击提交视图页面字段将保存到会话变量中。所以在网格分页和使用会话变量排序时，它将加载数据。

但是我想在点击预先搜索页面的链接时清除会话？怎么做？

Controller.php这样

public function actionAdvance_search()
    {
        $modelAdvSearchFinder = new AdvSearchFinder;
        print_r($_GET);
        if(isset($_POST) && isset($_POST['AdvSearchFinder']['submit']))
        {
            $this->clearAdvSearchSessionVar();

            Yii::app()->session['id'] = ( $_POST['AdvSearchFinder']['id'])? Yii::app()->session['id'] = $_POST['AdvSearchFinder']['id']:"";
            Yii::app()->session['name'] = ( $_POST['AdvSearchFinder']['name'])? Yii::app()->session['name'] = $_POST['AdvSearchFinder']['name']:"";
            Yii::app()->session['age'] = ( $_POST['AdvSearchFinder']['age'])?Yii::app()->session['age'] = $_POST['AdvSearchFinder']['age']:"";
            Yii::app()->session['class'] = ( $_POST['AdvSearchFinder']['class'])? Yii::app()->session['class'] = $_POST['AdvSearchFinder']['class']:"";
            Yii::app()->session['section'] = ( $_POST['AdvSearchFinder']['section'])? Yii::app()->session['section'] = $_POST['AdvSearchFinder']['section']:"";
            Yii::app()->session['Email'] = ( $_POST['AdvSearchFinder']['Email'])? Yii::app()->session['Email'] = $_POST['AdvSearchFinder']['Email']:"";
            $modelAdvSearchFinder->attributes = $_POST['AdvSearchFinder'];

        }
        $id = Yii::app()->session['id'];
        $name = Yii::app()->session['name'];       
        $age = Yii::app()->session['age'];
        $class = Yii::app()->session['class'];  
        $section = Yii::app()->session['section'];  
        $Email = Yii::app()->session['Email'];    

        $criteria=new CDbCriteria(array('distinct'=>true,));          
        $criteria->compare('id',$id,true);
        $criteria->compare('name',$name,true);
        $criteria->compare('age',$age,true);
        $criteria->compare('class',$class,true);
        $criteria->compare('sectionPerson',$section,true);  
        $criteria->compare('Email',$Email,true);

        if($id != "" || $name != "" || $age  != "" || $class   != "" || $section    != "" || $Email      != "" || $TelePhone1  != "" || $TelePhone2  != "" || $Fax  != "" || $Address     != "" || $State       != "" || $Suburb      != "" || $PostCode   != "" || $Include_inactive != "F")
        {   
            $modelSearch= new CActiveDataProvider("tblClass", array(
                'criteria'=>$criteria,
            )); 
        }
        else
        {
            $modelSearch = "";
            $this->clearAdvSearchSessionVar();
        }
       $this->render('advance_search',array('modelSearch' => $modelSearch,'modelAdvSearchFinder'=>$modelAdvSearchFinder));
    }

model.php

class AdvSearchFinder extends CFormModel
{

    public $id;
    public $name;
    public $age;
    public $class;
    public $section;
    public $Email;

    public function rules()
    {
        return array(
            array('id,name,age,class,section,Email', 'safe'),
        );
    }    
    public function attributeLabels()
    {
        return array(
            'id'=>'ID',
            'name'=>'Name',
            'age'=>'AGE',
            'class'=>'Class',
            'section'=>'section',
            'Email'=>'Email'
        );
    }

}

Answer 1

unset(Yii::app()->session['var']);

Answer 2

根据Orlymee的回答，您可以将其包装在控制器的支票中：

if(!Yii::app()->request->isAjaxRequest) { 
  unset(Yii::app()->session['var']);
}

Answer 3

我有两个可以帮助您保留网格过滤器的扩展程序：

remember filters扩展为CActiveRecord / Model实现的默认可能性添加了一些功能。

它将检测搜索场景，它将从GridView中保存过滤器。当您需要在页面更改期间在导航之间记住它们时，这很方便。对于大量导航和重度过滤，此功能可以通过几行激活。

它的对是clear filters

Answer 4

您可以使用jquery创建一个onclick事件，该事件将像其他用户所说的那样清除此会话：

unset(Yii::app()->session['var']);

Answer 5

我不明白为什么你使用会话来存储请求变量，因为YII CActiveDataProvider已经有了设置请求参数的选项，可以用于排序和放大。分页如下：

$params=array('id'=>$_POST['AdvSearchFinder']['id'],'name'=>$_POST['AdvSearchFinder']['name'])
$dataProvider=new CActiveDataProvider($CmdbMaster,array(
                'criteria'=>$criteria,
                'pagination'=>array(
                        'params'=>$params,
                ),
                'sort'=>array(
                        'params'=>$params,
                ),

        ));
