Joomla！ 管理面板中的自定义模块字段数据

Question

I would like to know how is it possible to call PHP file from backend panel. All should be done in the mod_.xml file

<fields name="params">
    <fieldset name="basic">
       <field
          name="myname"
          type="mycalledfile"
          label="mylabel"
          extension="mod_mymodule"
          description=""
       />
    </fieldset>
 </fields>

I found on the internet that extension attribute will call administrator/components/mod_mymodule/models/fields/mycalledfile.php , but thats wrong and I want to be able to call file from modules/ as this is a module. My point is to get data from certain file, or from database call. Either way this has to be done somehow with the .xml file, so this is available via backend admin panel of the module.

您可以在字段集中使用addfieldpath。

<fieldset name="basic"  addfieldpath="/administrator/components/mod_xml/models/fields">
