Question

我有这个错误：

PHP注意：未定义的偏移量：第59行/var/www/joomla/Joomla_3/modules/mod_menu/helper.php中的1

我在搜索后发现它可能是由于数组的第一个参数未定义。但是我尝试了很多东西，但是在没有通知的情况下我无法找到我应该改变的东西。

这是helper.php：

Answer 1

将其更改为：

|| ($start > 1 && !empty($item->tree[$start - 2]) && !in_array($item->tree[$start - 2], $path)))

empty（）将检查是否存在，并且它同时不为空。
