Question

我是yii框架中的新手。我正在尝试使用yii框架进行搜索操作。我有多个条件。

我收到了错误。尝试分配非对象的属性

C：\瓦帕\ WWW \ YII \框架\幅\ CPagination.php（216）

有人帮帮我吗？

我的控制器代码是

    <?php

 public function actionadvance_search_result()
  {
    $title=$_GET['title'];
    $experience=$_GET['experience'];
    $location=$_GET['location'];
    $criteria=new CDbCriteria();
    $criteria_new =NULL;
    if($experience!="")
    {
      $criteria_new = $criteria->condition = "(title like '%$title%' or  key_skills like '%$title%') and (experience like '%$experience%')";    
    }
    if($location!="")
    {
       $cri_location=$criteria->condition = "location_id like '%$location%'";       
       $criteria_new = $cri_location.' '.'and'.' '.$criteria_new;
    }
    $count=Job::model()->count($criteria_new);
    $pages=new CPagination($count);
    $pages->pageSize=2;
    $pages->applyLimit($criteria_new);
    $model=Job::model()->findAll($criteria_new);
    $number_rec=count($model);
    if($number_rec<=0)
    {
      $this->render('search_result1',array('model' =>$model));
    }
    else
    {
      $this->render('advance_search_result',array('model' =>$model,'pages' => $pages));
    }
 }
 ?>

Answer 1

我没有得到你想要实现的目标，但使用$criteria_new变量似乎是一个问题并且是多余的。在这里使用$criteria->addCondition()。

<?php

 public function actionadvance_search_result()
  {
    $title=$_GET['title'];
    $experience=$_GET['experience'];
    $location=$_GET['location'];

    $criteria = new CDbCriteria();

    if($experience!="")
    {
      $criteria->addCondition("(title like '%$title%' or  key_skills like '%$title%') and (experience like '%$experience%')");    
    }
    if($location!="")
    {
       $criteria->addCondition("location_id like '%$location%'");
    }
    $count=Job::model()->count($criteria);
    $pages=new CPagination($count);
    $pages->pageSize=2;
    $pages->applyLimit($criteria;
    $model=Job::model()->findAll($criteria);
    $number_rec=count($model);
    if($number_rec<=0)
    {
      $this->render('search_result1',array('model' =>$model));
    }
    else
    {
      $this->render('advance_search_result',array('model' =>$model,'pages' => $pages));
    }
 }

Answer 2

我希望$ criteria_new

中存在问题

当$ experience为NULL时，它将形成不完整的查询。

试试这个

   $criteria=new CDbCriteria();
   // $criteria_new =NULL; ---------> Remove it
   $condition='';
   if($experience!="")
   {
       $condition=(title like '%$title%' or  key_skills like '%$title%') and (experience like '%$experience%');
   }

   if($location!="")
   {
       if($experience!="")
       {
           $tempCond="location_id like '%$location%'";
           $condition=$condition.' AND '. $tempCond;
       } 
       else
       {
          $condition=$tempCond;
       }
   }

现在applyLimit（）应该是

   $pages->applyLimit($criteria);

搜索操作无法使用yii框架
