@usernames: Twitter Style Mentions - El Forum - 06-30-2012
[eluser]nitrammit[/eluser]
I'm trying to to build a Twitter style notification system that alerts users when their username has been mentioned on the site by another user.
For example, user1 wants to draw user2's attention a comment of his. He would post:
"You should ask @user2, he knows how to do it!"
I've worked out how to convert these mentions to links through the following function:
Code:
if ( ! function_exists('at_usernames'))
{
function at_usernames($content)
{
return preg_replace("#(^|[\n ])@([^ \"\t\n\r<]*)#ise", "'\\1<a >@\\2</a>'", $content);
}
}Which basically just turns the mention into a link, linking to the user's profile page.
But I'm not sure how to take the ACTUAL USERNAME mentioned and use it to add mentions into my database so I can then notify the mentioned user. I understand the CI/DB side of things, but how would I strip the username out? With regex?
[EDIT] I can't seem to post my actual code, it is being altered. Here's a screenshot instead:
