AyKay47 Posted April 4, 2012 Share Posted April 4, 2012 Are you using a date/datetime field to store the date in your db table? Quote Link to comment Share on other sites More sharing options...
charles07 Posted April 9, 2012 Author Share Posted April 9, 2012 yes AYKay47, it's in the time stamp format Quote Link to comment Share on other sites More sharing options...
dcro2 Posted April 9, 2012 Share Posted April 9, 2012 You can't really schedule queries to happen with just php or mysql. Use cron. http://www.htmlcenter.com/blog/running-php-scripts-with-cron/ */15 8-20 * * * php /path/to/php/file.php It all depends on what host you're on, if you have cPanel, etc. Quote Link to comment Share on other sites More sharing options...
AyKay47 Posted April 9, 2012 Share Posted April 9, 2012 In your query you will compare the timestamp field to NOW() Quote Link to comment Share on other sites More sharing options...
