1.创建tag 标签类

<?php

class GuyiTag extends TagLib
{
    /**
     * 自定义标签库，用于处理图片上传和图片显示。
     *
     *
     *
     * 标签参数说明：
     * - **module**: (string) 上传模块的名称，例如 'long'。
     * - **ids**: (string) 附件的 ID 列表，用逗号分隔，例如 '3380,3309'。
     * - **type**: (string) 文件类型，例如 'file' 或 'image'。
     * - **name**: (string) 输入框的 name 属性值。
     * - **idName**: (string) 外层 `<div>` 的 ID 名称，例如 'text_name'。
     * - **url**: (string) 文件上传的地址或 API 接口路径。
     * - **hideUp**: (boolean) 是否隐藏上传按钮，`true` 表示隐藏，`false` 表示显示。
     * - **accept**: (string) 文件格式限制，例如 'mp4,mp3,image/*'。
     * - **limit**: (int) 文件上传的最大数量，例如 9。

2.再config view 中加入配置

'taglib_pre_load'     =>    'app\XnmsTag',
