scootstah Posted August 6, 2012 Share Posted August 6, 2012 1. Use proper brackets. if($count>0) { echo "username exists"; } else { echo "not exists"; } 2. Don't use $_REQUEST 3. Sanitize input before using it with a database if(isset($_POST['dun'])) { $dun = mysql_real_escape_string($_POST['dun']); $sel=mysql_query("select username from reg where username='$dun'"); Your problem is the fact that you are terminating the script if there are no rows returned, on this line: $count=mysql_num_rows($sel) or die(mysql_error()); If mysql_num_rows() returns 0, the script is terminated and, since there is no MySQL error, you get no output. So, change it to $count=mysql_num_rows($sel); Quote Link to comment https://forums.phpfreaks.com/topic/266725-if-else-not-working/#findComment-1367128 Share on other sites More sharing options...
