Hai guys. So my problem is that My user.inc.php file is all correct but it shows the error
Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /home/a4495253/public_html/core/inc/user.inc.php on line 19
My user.inc.php file:
<?php
// Checks if the given username exists in the table.
function user_exists($user){
$user = mysql_real_escape_string($user);
$total = mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_name` = '{$user}'");
return (mysql_result($total, 0) == '1') ? true : false;
}
// Checks if the given username and password combination is valid.
function valid_credentials($user, $pass){
$user = mysql_real_escape_string(htmlentities($user));
$pass = sha1($pass);
mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_name` = '{$user}' AND `user_password` = '{$password}'");
return (mysql_result($total, 0) == '1') ? true : false;
}
// Adds a user to the Database.
function add_user($user, $pass, $first_name, $last_name){
$user = mysql_real_escape_string(htmlentities($user));
$pass = sha1($pass);
$first_name = mysql_real_escape_string(htmlentities($first_name));
$last_name = mysql_real_escape_string(htmlentities($last_name));
mysql_query("INSERT INTO `users` (`user_name`, `user_password`, `first_name`, `last_name`) VALUES ('{$user}', '{$pass}', '{$first_name}', '{$last_name}')");
}
