How to save datetime from MySQL into SESSION in php?

Question

How can I save 'date_time' which is a datetime type into a session so I can display ex. "Registered 2013-04-09 15:45:20" on the page secret_place.php

I have this code in login.php

$query = mysql_query("SELECT `user`, `pass`, `date_time` FROM `database` WHERE user = '".$user."' AND pass = '".$pass."' LIMIT 1");
if (mysql_num_rows($query) > 0) {
$_SESSION['logged'] = true;
$_SESSION['user'] = $user;

header('Location: secret_place.php');
}

Answer 1

Give this a try,

$query = mysql_query("SELECT `user`, `pass`, `date_time` FROM `database` WHERE user = '".$user."' AND pass = '".$pass."' LIMIT 1");
if (mysql_num_rows($query) > 0) 
{
   $_SESSION['logged'] = true;
   $_SESSION['user'] = $user;
   while ($row = mysql_fetch_assoc($query)) 
   {
       $_SESSION['date_time'] = $row['date_time'];
   }
   header('Location: secret_place.php');
}

There are some serious issues, here: First of all, please, don't use mysql_* functions in new code . They are no longer maintained and are officially deprecated . See the red box ? Learn about prepared statements instead, and use PDO , or MySQLi - this article will help you decide which. If you choose PDO, here is a good tutorial . That way you'll also prevent SQL injection attacks , right now your code is wide open to them.

Also do not store plain password in the DB. Store it hashed, using some proper lib, like PasswordLib
