Question

Passing sessions variables through an iframe, php

Answer 1

+1 A:

You have to use session_start() in both scripts, the one setting the values (and presumably printing the <iframe>-element?) and the script that produces the contents for the iframe.

e.g. the "outer" script

<?php // test.php
session_start();
$_SESSION['productcheck'] = array();
$_SESSION['productcheck'][] = 'A';
$_SESSION['productcheck'][] = 'B';
$_SESSION['productcheck'][] = 'C';
session_write_close(); // optional
?>
<html>
  <head><title>session test</title></head>
  <body>
    <div>session test</div>
    <iframe src="test2.php" />
  </body>
</html>

and the script for the iframe content

<?php // test2.php
session_start();
?>
<html>
  <head><title>iframe session test</title></head>
  <body>
    <div>
      <?php
      if ( isset($_SESSION['productcheck']) && is_array($_SESSION['productcheck']) ) {
        foreach( $_SESSION['productcheck'] as $pc ) {
          echo $pc, "<br />\n";
        }
      }
      ?>
    </div>
  </body>
</html>

Answer 2

A:

Not sure what's up with your session variables, but you can definitely pass all four variables through the url in your iframe. You just need to separate your key value pairs with an ampersand. So something like this:

file.php?key1=val1&key2=val2&key3=val3 and so on.

This is probably a better way than using session variables if your just trying to get data into that other file.
