AndyB Posted July 14, 2007 Share Posted July 14, 2007 I am getting blank screen. Absolutely nothing displayed at all? All of your $_POST[xyz] should be $_POST['xyz'] Link to comment https://forums.phpfreaks.com/topic/59992-php-form/#findComment-298370 Share on other sites More sharing options...

rbvinc Posted July 14, 2007 Author Share Posted July 14, 2007 Continuing on previous reply, I tried northwind access database, it works fine with php (windows 2000/access 2000/php), I tried <?php phpinfo() ?>, this works fine. Only the above email problem, and mysql connection. I cannot connect thru php, but I can see dbs, tables, thru 'navicat' mysql editor.
