Ideally, you would have 3 tables like so...
Projects(with one record per project) --------- projectID |ProjectName| etc... 1 my project 2 another project Users(with one record per user) ------- userID| userName| etc... 123 Joe Blow 124 Mary Jane ProjectsVerified ---------------- projectID| userID 1 123 1 124 2 124 In this example, Joe has verified my project only. Mary Jane has verified "my project" and "another project". Whether you use my database or yours, you will need to use SQL's JOIN syntax to properly extract the information you are looking for. Read up on SQL and JOIN types, (LEFT, INNER, OUTER etc.). They are tricky at first but well worth it once you figure out what is going on. Or just repost, and someone will help you out with it.

Other users will verify those projects. What I'm trying to do is once a user verify a project he/she cannot view it anymore, but I want to keep it available for the other users that haven't verified it. I have two tables project and user_verified. On project table I keep all the projects that users post. On user_verified I keep users who already verified for a project. These are the fields for user_vefified table project_id, username, verified Everytime a user verifies a project I insert a new record to the user_verified table. This the query, but it doesn't work. It selects the same record from the two tables. e.g. if the records exist twice on the user_verified table and one on the project table, it will display three records when I run the the following query: $sql = "SELECT project.project_id, project.project_name, project.project_desc FROM project, user_verified WHERE project.username <> user_verified.username AND project.username <> '$PHP_AUTH_USER' AND project.category='$category')"; any help is greatly apprecciate it Thanks in advance Nato -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
