Question

我想在joomla 3后端模块中上传文件。

我提到https://docs.joomla.org/How_to_use_the_filesystem_package但没有出现文件上传按钮。也许我弄错了或把它放在错误的文件中？

任何人都可以提供帮助？：d

谢谢。

下面是.xml文件和语言标签之间的代码。

<params>
    <param name="dir" type="text" label="Directory" description="Directory Upload" default="upload"/>
    <param name="type" type="list" default="*" label="Select a file type" description="File type">
         <option value="*">Any File </option>
         <option value="image/png">PNG</option>
         <option value="image/gif">GIF</option>
         <option value="image/jpeg">JPEG</option>
         <option value="application/zip">ZIP</option>
         <option value="application/x-gzip">TAR.GZ</option>
         <option value="text/html">HTML</option>
         <option value="text/plain">TXT</option>
         <option value="application/pdf">PDF</option>
         <option value="application/msword">DOC</option>
       </param>          
    <param name="user_names" type="text" label="User Names (optional)" description="Names users (optionas)" default=""/>

在定义（＆＃39; _JEXEC＆＃39;）之后的mymodule.php中，或者死亡（＆＃39;限制访问＆＃39;）;＆＃39;线。

好的2件事是错的。

首先，您使用<params>这是参数字段的旧方法。您需要使用以下文档中显示的字段：

https://docs.joomla.org/J3.x:Creating_a_simple_module/Adding_Form_Fields

其次，您的mymodule.php文件用于模块的前端，除了抓取参数等数据外，不会与后端有任何关系。

您可以使用创建media的custom form field类型字段。

希望这有帮助
