I got this problem
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /var/www/html/infobangla/normal_user_reg.php on line 19

what is the problem?

First of all - Post your code.
Secondly, this error usually means there was a problem with your SQL. Do your code like this:

Code: [Select]

<?php
$sql = "SQL HERE";
$result = mysql_query($sql) or die(mysql_error().' SQL: '.$sql);
?>
