Disabling page view if not logged in.

[kinks]

So, I have all of my user stuff set-up, login, register, databases, tables, etc, etc.

 

How do I do a simple PHP code or script that disables page view if not logged in?

[mikesta707]

if(!isset($_SESSION['my_session_variable'])){
die("YOU AINT LOGGED IN");
}

 

include that on pages you want to protect

if(!isset($_SESSION['my_session_variable'])){

}

Thank you so much!

<?php
session_start();

if ($_SESSION['loggedIn'] != 'admin')
{   //check the registered user, if not go index.php 
if(!$_SESSION['id'])
{
	header("location:index.php"); 
	die();
}
else
{
  echo " <script language='JavaScript'>history.go(-1);</script>";  
}
}
?>

I used

<?php
session_start();

if(!isset($_SESSION['my_session_variable'])){
die("You cannot view this page, you are not logged in!");
}
?>

 

BUT, it displays the message for logged in users as well.

OK, when a user logs in, set a variable, along with all the other variables you set, such as username, id, email, etc.:

 

$_SESSION['logged'] = TRUE;

 

Next, whenever you want to hide/disable something, or do something for non logged in users, do this, here are some examples:

 

Redirect to login page:

session_start();
if(!$_SESSION['logged']){
     header("Location: login.php");
     exit;
}

 

Display a login form or a user navigation bar:

session_start();
if(!$_SESSION['logged']){
     echo '<form action="login.php" method="post">
          <p><input type="text" value="Username" name="username" /></p>
          <p><input type="password" name="password" /></p>
     </form>';
}else{
     echo '<a href="home.php">Home</a> | <a href="logout.php">Logout</a>';
}
