i used two tables for the account and the info, profile, users.
here is my code:
user.inc.php
<?php
function fetch_current_user_id($username){
$username = mysql_real_escape_string($username);
$sql = "SELECT `user_id` FROM `users` WHERE `user_name` = '{$username}'";
$result = mysql_query($sql)or die(mysql_error());;
$value = mysql_result($result, 0);
return $value;
}
if(empty($_SESSION['uid'])) {
$_SESSION['uid'] = fetch_current_user_id($_SESSION['username']);
}
function fetch_users() {
$result = mysql_query('SELECT `user_id` AS `id`, `user_name` AS `username` FROM `users`')or die(mysql_error());;
$users = array();
while (($row = mysql_fetch_assoc($result)) !== false) {
$users[] = $row;
}
return $users;
}
function fetch_user_info($uid){
$uid = (int)$uid;
$sql1 = "SELECT

$result = mysql_query($sql1)or die(mysql_error());;
return mysql_fetch_assoc($result);
}
function fetch_user_acc($uid){
$uid = (int)$uid;
$sql1 = "SELECT
`user_name` AS `username`,
`user_password` AS `password`
FROM `users`
WHERE `user_id` = {$uid}";
$result = mysql_query($sql1)or die(mysql_error());;
return mysql_fetch_assoc($result);
}
//checks if the given username exists in the database
function user_exists($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;
}

function valid_credentials($user, $pass){

I tried using INNER JOIN for the 2 tables and doesn't seem to work, so i tried using two functions for fetching info, updating, and also adding data in the database.I'm kind of a beginner in php (sorry about that) and i don't know what or how to fix the errors, i tried searching on Google how to fix the errors and i can't find anything.
P.S.Thanks for the Tutorial and i learned a lot for a beginner
Sorry for asking and Thanks again!
