yii添加行的增删改查

效果图：

控制器：

<?php
namespace backend\controllers;
use Yii;
use yii\web\Controller;
use backend\models\Zhan;

class IndexController extends Controller
{
   //显示页面
   public function actionIndex()
   {
        $index=new Zhan();
        //接受值
         if($_POST)
         {

            //判断是否有删除ids
            if(Yii::$app->request->post('ids'))
            {
               $ids=Yii::$app->request->post('ids');
               $str='';
               for($i=0;$i<count($ids);$i++)
               {
                  if($a->createCommand()->delete('zhan',['id'=>$ids[$i]])->execute())
                  {
                     $str++;
                  }
               }
               if($str!='')
               {
                   echo '<script>alert("删除成功");location.href="index.php?r=index/index"</script>';
               }
            }
            else

                  //print_r($id);die;
                  //添加行的数据
                  $names=Yii::$app->request->post('zhan_name');
                  $ulrs=Yii::$app->request->post('url');
                  //遍历数组

                     }
                     else

                        $url=$ulrs[$k];
                        $xu_id=$xu_ids[$k];
                        $name=$v;
                        $res=$a->createCommand()->insert("zhan",['xu_id'=>$xu_id,'zhan_name'=>$name,'url'=>$url])->execute();

                        }      
                     }
                 }
            }
         }
         else
         {

            $models=Zhan::find()->orderBy(['xu_id'=>'asc'])->asArray()->all();
            //var_dump($models);
            return $this->renderPartial("show",['models'=>$models]);
         }
   }
}
?>
