Hey, I've got a question. Why do I get the error [i]Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:\WEBS\webdirectory\online.php on line 38[/i] Some odd reason I just don't see the problem. Coudl someone point me to what is wrong? Here is the code: [code]$sql = mysql_query("SELECT * FROM ".$sql_prefix."users_online WHERE country = '".ip2country($ip)."'",$conn); if(mysql_num_rows($sql) > 0){ $select_tes_lgi = mysql_query("SELECT * FROM ".$sql_prefix."visits WHERE ip = '".$ip."' LIMIT 1",$conn); if(mysql_num_rows($select_tes_lgi) != 0){ $sel = dosql($sql,1); $hit_add = (($sel[0][2]) + (1)); mysql_query("UPDATE ".$sql_prefix."visits_status SET hits = '".$hit_add."' WHERE country = '".ip2country($ip)."'"); } }else{ mysql_query("INSERT INTO ".$sql_prefix."visits_status (hits,country) VALUES ('1','".ip2country($ip)."')"); }[/code] I just don't see the problem. Thanks if someone could help.
