Yii 利用layer删除数据

一、视图

        <tr );
        });
    }
})
</script>

            $.ajax({
                type:"POST",
                url:"/admin/event/category_del",
                data:{category_id:category_id},
                dataType:"json",
                success:function(data){
                    if(data.msg == 1){
                        layer.msg('删除成功！', {icon: 1,time:1000});
                    } else {
                        layer.msg('删除失败！', {icon: 2,time:1000});
                    }
                }
            })

二、控制器

    public function actionCategory_del()
    {
        $category_id = $_POST['category_id'];
        $model = Category::model()->findByPk($category_id);
        if($model->delete()){
            echo json_encode(array('msg'=>1));
        }
    }

 三、其他 带图片删除

    public function actionDel()
    {
        $mp_id = $_POST['mp_id'];
        $model = Mp::model()->findByPk($mp_id);
        if(is_file($model->img_url)){
            unlink($model->img_url);
        }
        if(is_file($model->qrcode_url)){
            unlink($model->qrcode_url);
        }
        if($model->delete()){
            echo json_encode(array('msg'=>1));
        }
    }
