推荐答案

事实证明，作者遗漏了一个非常简单的修复方法和一般的良好做法，即在尝试设置属性之前始终应初始化对象.解决这个问题的非常简单的方法是在它试图访问的变量出现错误之前添加一个 new StdClass; 调用.

As it turns out, the author missed a very simple fix and general good practice that you should always initialize your object before you try to set a property. The very simple fix for this is simply to add a new StdClass; call right before the error with the variable it is trying to access.

$items[$i] = new StdClass;
$items[$i]->title   = $crs_post_title;

第一行将修复显示警告.

That first line will fix the warning from showing up.

这也将通过以下修复解决 /components/com_community/models/activities.php on line 387 中的问题.

This would also fix the problem in /components/com_community/models/activities.php on line 387 with the following fix.

$commentsResult[$comment->type . '-' . $comment->contentid] = new StdClass;
$commentsResult[$comment->type . '-' . $comment->contentid]->_comment_count = 0;
