Hello there, I recently bought XF and I have some questions about the addons system. Especially how XenForo_Input and events works. Coming from VB3, I could easily change a thread title before it was posted just by doing PHP: $title = "New Title" How can I edit the title, I already know about the XF overriding system, I just need to know how to modify the XenForo_Input or pass the new arguments to the original function. For the events part, VB3 allowed me to hook at some predefined places. For example : allows you to hook and execute your code right after the thread is created. Therefore you can then award points for it or whatever you want to do. Is there any way to execute a code before a thread is made and another one after the post is made? If anyone got any ideas for me! Thanks you.
