Yii 利用layer删除数据

一、视图

        <tr id="rm_<?php echo  $v->category_id;?>">
            <td><?php echo  $v->category_id;?></td>
            <td><?php echo  $v->category_title;?></td>
            <td><a href="/admin/event/category_edit/id/<?php echo  $v->category_id;?>">修改</a> |

                <a href="javascript:;" onclick="del(<?php echo  $v->category_id;?>)">删除</a></td>
        </tr>
    <?php endforeach;?>
    </table>
</div>
<script>
$(function(){
    del = function (s){
        var category_id = s;
        //询问框
        layer.confirm('您确认要删除吗？', {
            btn: ['确认','取消']
        }, function(){
            $.post("/admin/event/category_del",{category_id:category_id},function(data){
                if(data.msg == 1){
                    layer.msg('删除成功！', {icon: 1,time:1000});
                    $("#rm_"+category_id).remove();   //这里用remove删除,刷新页面影响分页
                } else {
                    layer.msg('删除失败！', {icon: 2,time:1000});
                }
            },"json");
        });
    }
})
</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));
        }
    }
