dodgexxx Posted September 28, 2008 Share Posted September 28, 2008 Hi I'm a total newbie with this, but I'm trying to make a serch engine for my mp3 collection. I found myself a code and tried it out. It's almost working too. But I'm getting a message saying: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /volume1/Web/tmp/search.php on line 48 Even though it's working pretty good, I don't know why this message means. So, if anyone would like to take a closer look at the code, here it is: <!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”> <html xmlns=“http://www.w3.org/1999/xhtml”> <head> <meta http-equiv=“Content-Type” content=“text/html; charset=utf-8” /> <title>Rogers Personal MP3 Search!</title> </head> <body> <h1 align="center">Rogers MP3 Search Engine with PHP/MYSQL</h1> <p align="center"> <a href="http://www.bjorbekk.net/mp3/search/" ><b>New Search</b></a> <p></p> </form> </body> </html> <?PHP function getmicrotime() { list($usec, $sec) = explode(" ", microtime()); return ((float)$usec + (float)$sec); } //initializing connection to the database $connection_string = dirname(__FILE__) .
