requinix Posted April 19, 2011 Share Posted April 19, 2011 Add a userid field to the messages table... Link to comment https://forums.phpfreaks.com/topic/234169-linking-tables/#findComment-1203591 Share on other sites More sharing options...
hoponhiggo Posted April 19, 2011 Author Share Posted April 19, 2011 Thats what i want to do, but i dont understand how to make sure the two userid are the same. If a new user registers, the userid in the users table auto increments. How would the userid make its way to the messages table?

requinix Posted April 19, 2011 Share Posted April 19, 2011 When they're posting messages they aren't new anymore. They exist in the system. And if they exist they must have an ID number. When you logged them in you must have queried the database. When you do so, grab the user ID. Then when they post messages, stick that ID into your INSERT query.
