如何对同一搜索模型使用condition()和addcondition()

Question

我有一个条件为"upload_date = today"的网格视图,但是当我搜索其他日期时,它不会过滤网格.这是我的模型:

public function search()
{
    // Warning: Please modify the following code to remove attributes that
    // should not be searched.
    $date=date('Y-m-d');
    $criteria=new CDbCriteria(array('order'=>'upload_date ASC'));
    $criteria->condition = "upload_date='$date' ";
     if(isset($_GET['upload_date']))
           {
           $criteria->addCondition('upload_date = :upload_date','AND'); 
          $criteria->params[':upload_date'] = $this->upload_date;
             }

    $criteria->compare('book_id',$this->book_id);
    $criteria->compare('date_received',$this->date_received,true);
    $criteria->compare('batch',$this->batch,true);
    $criteria->compare('isbn_no',$this->isbn_no,true);
    $criteria->compare('book_title',$this->book_title,true);
    $criteria->compare('auther_name',$this->auther_name,true);
    $criteria->compare('upload_date',$this->upload_date,true);

    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
        'pagination'=>array(
        'pageSize'=>50
        ),

    ));
}

我试图在同一搜索中同时使用条件和addcondition.我在上面的模型中做错了什么？

试试这个:

public function search()
{
 $criteria=new CDbCriteria(array('order'=>'upload_date ASC'));

 if(isset($_GET['ModelName']['upload_date']))
 {
  $criteria->compare('upload_date',$this->upload_date,true);
  // $criteria->addCondition('upload_date = :upload_date');
  // $criteria->params[':upload_date'] = $this->upload_date;
 }
 else 
 {
  $date=date('Y-m-d');
  $criteria->condition = "upload_date='$date' "; 
 }
  $criteria->compare('book_id',$this->book_id);
  $criteria->compare('date_received',$this->date_received,true);
  $criteria->compare('batch',$this->batch,true);
  $criteria->compare('isbn_no',$this->isbn_no,true);
  $criteria->compare('book_title',$this->book_title,true);
  $criteria->compare('auther_name',$this->auther_name,true);
  $criteria->compare('upload_date',$this->upload_date,true);

  return new CActiveDataProvider($this, array(
     'criteria'=>$criteria,
     'pagination'=>array(
     'pageSize'=>50
     ), 

 ));
}

您不需要addCondition,特别是因为您要向同一列添加条件.

编辑:
在您已设置的主要初始条件中upload_date = $date,现在如果您添加条件,例如$_GET['ModelName']['upload_date']由过滤器中的用户提供,您的实际数据库查询将变为类似select * from tbl_name where upload_date = 'xxx' and upload_date = 'yyy',此处为xxx = $ date,yyy = date由用户提供.现在,如果xxx!= yyy,查询将如何返回任何值？这不可能.

希望你得到这个解释.
