When I tried to retrieve data from phpmyadmin database using PHP script I used a hidden filed and passed "user_id" but then I am getting an error about the undefined variable. The code is below.
And I also want to make the header responsive but no luck after trying lots of solution. I have tried every possible solution using so many websites but I can't make it work.
The code is below.
<?php
session_start();
include 'lib/dao.php';
include 'lib/model.php';
$d = new dao();
$m = new model();
extract($_POST);
if(!isset($_SESSION['user_id']))
{
header("location:login.php");
}
$q=$d->select("user","user_id='$user_id'");
$data=mysqli_fetch_array($q);
?>
