Shibboleth passes several variables relating to the user in the $_SERVER array. The two variables of most use (and used in the example below) are:

• eppn (a unique identifier, in the form <userID>@ncl.ac.uk)

• mail (your University email address)

Using Shibboleth headers in a PHP web form

In the example below, the user will enter form data (in the "<other form fields>" section) and, when the form is submitted, the username and email address of the user logged into Shibboleth will be transmitted - along with the user-entered information - to the page specified in the form's action parameter.

Code:

<?php
  $name = $_SERVER['eppn'];
  $email = $_SERVER['mail'];
?>

<form action="result.php" method="post">
  <input type="hidden" name="name" value="<?php echo $name; ?>" />
  <input type="hidden" name="email" value="<?php echo $email; ?>" />   
  .   
  .   
  <other input fields>
  .
  .   
  <input type="submit" value="Submit" />
</form>
