Re: SV: [PHP-DB] Query construction (again)

Thanks for that - but I just sorted it literally 10 seconds ago! I used: $sql = "SELECT * FROM $tabitem WHERE DATE_ADD(submitDate, INTERVAL 8 DAY) > CURDATE()"; Something happens with using INTERVAL 7 DAY though, in that only 6 days worth of posts are displayed, so 8 will have to suffice! Thanks very much!
