When I reload a page I seem to get disconnected from the session that I have created. I have added session_start() at the top of all my pages. I have even tried adding session_save_path("C:\xampp\tmp"); which I saw suggested on here but when it the user_id Session still disappears when I reload the page. This code above is saved in a file and included into all my pages where I need to get the $user_id variable. It works fine when i log in but then when I try go to another page I get this
Notice: Undefined index: user_id in C:\xampp\htdocs\php\goal\external\user_id.inc.php on line 7 Failed to find sessions.
<?php
session_save_path("C:\xampp\tmp");
session_start();
include 'connect.inc.php';
if($user_id == $_SESSION["user_id"]){
echo 'session found';
$user_id=$_SESSION["user_id"];
print_r($_SESSION);
}else{
echo 'Failed to find sessions.';
};
?>
Below is the code that creates the Session.
<?php
require_once'core.inc.php';
if(isset($_POST['username']) && isset($_POST['password'])){
$username=$_POST['username'];
$password=$_POST['password'];
if(!empty($username) && !empty($password)){
$query_verify = "SELECT `password` FROM `users` WHERE `username` =
'".mysql_real_escape_string($username)."'";
$hash = mysql_query($query_verify);
$password_verified=password_verify($password, $hash);
if($password_verified=true){
$query = "SELECT `id` FROM `users` WHERE `username` =
'".mysql_real_escape_string($username)."'";
if($query_run = mysql_query($query)){
$query_num_rows =
mysql_num_rows($query_run);
if($query_num_rows == 0){
echo 'You have entered a wrong username or
password';
}else if($query_num_rows == 1){
$user_id = mysql_result($query_run, 0 , 'id');
$_SESSION['user_id'] = $user_id;
header('Location: home.php');
exit();
}
}
}
}else{
echo("Please enter a username and password.");
}
}
?>
<form action ="<?php echo $current_file;?>" method="post">
Name: <input type='text' name='username'/><br>
Password: <input type='password' name='password'/>
<input type='submit' value='Log in'/>
</form>
