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，它没有过滤网格。这是我的模特：

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。

修改：
在您的主要初始条件中，您已经设置了upload_date = $date，现在如果您为其添加条件，请说明过滤器中用户提供的$_GET['ModelName']['upload_date']，您的实际数据库查询将变为select * from tbl_name where upload_date = 'xxx' and upload_date = 'yyy' ，这里xxx =你给的日期，yyy =用户提供的日期。现在，如果xxx！= yyy，查询将如何返回任何值？这是不可能的。

希望你得到这个解释。

如何对同一搜索模型使用condition（）和addcondition（）
