Question

我在我的表单中添加了行功能，而在更新表单上我需要更新旧数据，如果在表单中添加了任何新行，则在我的数据库中插入新数据我怎么能在YII中执行。我的控制器代码是

if(isset($_POST['LeadTargetEducation']))
{
    $target = new LeadTargetEducation; 
    $count= count($_POST['LeadTargetEducation']);               
    $target->attributes=$_POST['LeadTargetEducation'];

    //the value for the foreign key 'groupid'
    $lead_id = Yii::app()->db->createCommand()
          ->select('max(id) lead')
          ->from('lead_details')
          ->queryRow();

    $val=$lead_id['lead'];
    for($i=0;$i<$count;$i++)
    {       
        $target->lead_id=$val;
        $target->edu_id=$_POST['LeadTargetEducation'][$i]['edu_id'];
        $target->country_id=$_POST['LeadTargetEducation'][$i]['country_id'];
        $target->universty_id=$_POST['LeadTargetEducation'][$i]['universty_id'];
        $target->academic_year=$_POST['LeadTargetEducation'][$i]['academic_year'];
        $target->sub_edu=$_POST['LeadTargetEducation'][$i]['sub_edu'];
        $target->course_id=$_POST['LeadTargetEducation'][$i]['course_id'];
        $target->req_prior_target_edu=$_POST['LeadTargetEducation'][$i]['req_prior_target_edu'];
        $target->add_course=$_POST['LeadTargetEducation'][$i]['add_course'];        
        $target->save();                
     }
}

Answer 1

每次尝试保存新模型时都缺少新模型，这样做是为了防止更新同一记录：

for($i=0;$i<$count;$i++)
{       
    $target = new LeadTargetEducation(); // see this line
    $target->lead_id=$val; // I issume this is not the primary key!
    .
    .        
    .
    $target->save(); // and finally save it
 }

Answer 2

以下是beforesave方法的示例;您可以在模型中创建beforesave函数

function beforeSave(){
  $tableB = new new LeadTargetEducation();
  $tableB->edu_id = $this->edu_id;
  more...

  $tableB->save();
}

更新旧行并插入yii中的new
