This piece is completely wrong:
if(isset ($_SESSION['message']));?> //<-- : not ;
<div class="alert alert-<?=$_SESSION['msg_type']?>">
<?php
echo $_SESSION['message'];
unset($_SESSION['message']);
//<-- no closing tag
<?php endif ?> //<-- missing ;
Should be:
if(isset ($_SESSION['message'])):?>
<div class="alert alert-<?=$_SESSION['msg_type']?>">
<?php
echo $_SESSION['message'];
unset($_SESSION['message']);
endif; ?>
It get's pretty ugly when you use a lot of PHP and HTML in the same file, it might be time to look at using a template engine.

My current problem is that the Mysql entry is never updated.
This section runs:
header("location: list.php?=".$resname1.$rescity1);
So I know every condition is met correctly
Note: I added this part to know their values when redirected to list.php:
.$resname1.$rescity1
I ran all the code inside a PHP shell and it worked perfectly.
Of course, I had to set the values resname1 and rescity1 manually, so I'm thinking it must be some formatting issue?
Hello good afternoon, I'm having the trouble of not being able to use add a $_POST value to my $_SESSION variable so that I can use it later in my profile file.
I can give it other values like "hello" outside the if and it echoes hello in levraiprofilewesh.php.
I've tried making $_SESSION a super global variable and global but it didn't work.
I've been stuck on it for a few hours :(.
I don't need to upload the website on the web, it's just for local use, so there's no need for privacy feedback although it has helped me for the future.
login.php code:
<?php
session_start();
include("db_connect.php");
if(isset($_POST['login_button'])) {
$user_email = trim($_POST['user_email']);
$user_password = trim($_POST['password']);
$_SESSION['password'] = $user_password;
$usql = "SELECT * FROM users WHERE Email='$user_email' && Password='$user_password'";
$uresult = mysqli_query($db, $usql) or die("database error:". mysqli_error($db));
$urow = mysqli_fetch_assoc($uresult);
//while($row = mysqli_fetch_array($uresult))
//$STPMARCHEFRERE = $row['Firstname'];
//$SESSION = $row['Firstname'];
if($urow['Password']==$user_password){
setcookie("userid",$user_password,time()+(60*60*24*7));
setcookie("useremail",$user_email,time()+(60*60*24*7));
//$GLOBALS['SESSION'] = $user_password;
$time=time();
$queryz = "UPDATE Users
Set Online='Online',
Time='$time'

And your code is fully prone to SQL injection
Read about the PHP Prepared statements.
https://www.w3schools.com/php/php_mysql_prepared_statements.asp
Suppose file 1 name is codefile.php and file 2 containing connection is connection.php So, write in codefile.php include("connection.php")
Change $db to $conn in codefile.php as in connection.php, you have created connection in $conn variable
Check below link:
w3schools.com/php/php_includes.asp
codefile.php
<?php
include("connection.php");
$results = mysqli_query($conn, "SELECT * FROM info");
?>
