I'm trying to pull data off my sql table with php unique to the session's ID, however I only get the position that the user is in when I echo anything out!
<?php
include 'core/init.php';
$user_info = $_SESSION['user_id'];
?>
<html>....
<h1><?php echo $user_info['firstname'];?> <?php echo $user_info['firstname'];?> </h1>
displays as:
if I log in with the fifth position in the database!
484
The reason why you are getting 5 is for this code:
<?php echo $user_info['firstname'];?>
is that $_SESSION['user_id'] 's value is 5. So after the assignment $user_info's value is 5. Now because the $_SESSION['user_id'] is not set to an array as your intention seems to be. The result is that $user_info is taken as a string and ['firstname'] evaluates to [0]. If you like, you can update the ID 5 to 54, etc. You will always get the first character of your ID.
To correct this, try changing the last 2 lines before the return in your user_data function to:
$data = mysql_fetch_assoc(mysql_query("SELECT $fields FROM `users` WHERE `user_id` = $user_id"));
$data = array_merge(array($user_id), $data);
return $data;
if (logged_in() === true) {
$user_data = user_data($_SESSION['user_id'], 'username', 'first_name', 'last_name', 'email');
$user_data = user_data($session_user_id, 'user_id', 'username', 'first_name', 'last_name', 'email');
}
to:
if (logged_in() === true) {
$user_data = user_data($_SESSION['user_id'], 'username', 'first_name', 'last_name', 'email');
$_SESSION['user_id'] = $user_data;
}
