A customer previously had a strange requirement that he wanted his forum member registration to disable the function of receiving reply notifications by default. let's talk about the function, in fact, as the name implies, this setting is used to send notifications to members every time a post has a reply. the method of disabling the notification is generally set by the user's own membership system, however, this webmaster wants all users to be disabled by default. There are two ways to implement this function. The following is a simple example.
Method 1:
X3 open source/include/post/post_newthread.php
Find $ allownoticeauthor = 1;
Change to: $ allownoticeauthor = 0; // then update the cache. this method is recommended for ease and convenience.
