Need advice about transfering HTTP_REFERER to another page

Question

So I'm currently trying to save page1.php's HTTP_REFFERER as a variable and transfer that variable to another page. I've tried using $_SESSION[] and $_COOKIES[] methods but it didn't work. page2.php shows referrer as page.php.

Any suggestions?

page1.php :

<?php session_start();
$variable1 = $_SERVER['HTTP_REFERER'];
$_SESSION['ref'] = $variable1;

page2.php :

<?php session_start();
$_SESSION['ref'] = $variable1;
echo $variable1; ?> 

Answer 1

You inverted the variable and the value in your 2nd page

<?php
session_start();
$variable1 = $_SESSION['ref'];
echo $variable1;

Answer 2

$_SERVER['HTTP_REFERER'] is a predefined env variable. To access stored variable use for example $_SESSION['HTTP_REFERER'] on page2.php

Answer 3

In page1.php, make sure to end the code correctly:

<?php session_start();

  $variable1 = $_SERVER['HTTP_REFERER'];

  $_SESSION['ref'] = $variable1;

?>

In page2.php just print_r the $_SESSION['ref'] or assign it to a variable and then use echo.

Also the order of the variables is incorrect, should be:

$variable1 = $_SESSION['ref'];

HTH.
