我对此很陌生，但我想学习...

我有一个我想使用的 GPL 插件（用于 Joomla 1.6 / JomSocial 2.6）（w/Joomla 2.5 和 JomSocial 2.8），但它需要一些修复或更新。它应该检查默认头像并将其替换为随机头像。它安装但不起作用。

  1. 我如何验证它是否获得了所需的数据？

  2. 我认为一个问题可能是数据库中没有列出默认文件。看起来这个插件希望有一个。

    function onUserLogin($user, $options)
{
    $juser = CFactory::getUser($user);
    $curavatar = $juser->getThumbAvatar();

    $gender = $juser->getInfo($this->params->get( 'genderfield' , 'FIELD_GENDER' ));

    if($this->compareEnd("default.jpg", $curavatar) || $this->compareEnd("user.png", $curavatar) || ($this->contains('minisocialgender_images',$curavatar) && $this->params->get( 'reassign' , '0' )))
    {

该脚本只有大约 100 行，所以我希望有人能指出一些明显的问题。

感谢您的关注以及您可以提供的任何帮助。这是脚本的其余部分...
