Hello everyone!
Thanks for programming PHPBB!!
I've been using phpBB for few years, making some mod sometimes, and I'm looking to improve my PHP skills over time.
I have a 3.3.10 installation now and would like to make some changes by approaching the creation of extensions.
I would like not to directly modify phpBB's PHP files but rather make integrations so that they can be maintained over time, even with future updates.
I have a forum that interacts with a website. On the site, I've recreated and assigned the same login as the forum (IN PHPBB TRUE), so the navigation is closely linked to the forum. but it uses another db.
So far, I've modified some functions in the template to integrate the forum and the site.
like...
SQL phpbb-DB
SQL website-db
same host, different name, user and psw
However, I'd like to go further. I have some text lines in a secondary database (simply containing links) that I would like to display in the forum, particularly on the posting.php page (or specifically when someone wants to reply to a topic). I would like that, beneath the text area, there is a list of the last 15 lines from a secondary database. All of this to avoid affecting the main phpBB database.
Creating it statically in HTML is simple. You just need to modify and insert an "event" in the posting_editor_message_after.html position. The problem arises when I want to insert these 15 links as the latest ones with an SQL query:So, I tried to find a method to connect to this second database, but without success. I attempted to use the wiki, but I have a "basic" knowledge of PHP. I've always copied and adapted code, gradually learning its structure, but I'm still far from proficient in PHP. Image may be NSFW.
Clik here to view.
Nevertheless, I tried to create this PHP event (thank www and gpt for helping Image may be NSFW.
Clik here to view. ), but the result is only causing the forum to crash with errors on the posting page.
Could someone help me build this function?
Thank you very much!
