[SOLVED] how do I redirect a page back to a dynamic url?

[poleposters]

Hi,

 

Can anyone let me know  if this is  possible?

 

My site displays several pages of listings. But on the right hand side of the page I have a newsletter signup form. If someone decides to signup while theyre browsing, I want them to return automatically to the page they were viewing.

 

For example after the newsletter script runs I'd like them to return to the URL

 

http://localhost/searchcat.php?catid=1&searchterm=2000&start=10 which is the second page of results with the category id '1' and the search term '2000'.

 

Any clues?

 

Cheers

There are two options:

 

1) On the script the form submits to, use the value of $_SERVER['HTTP_REFERER']

<?php
  $referer = isset($_SERVER['HTTP_REFERER'])
    ? $_SERVER['HTTP_REFERER']
    : 'index.php'; //Default value in case there is no referer
  header('Location: '.$referer);
  exit;
?>

 

 

2) In the form, have a hidden field called referer, and set the value of it to $_SERVER['REQUEST_URI']

<form method="post" action="subscribe.php">
  <input type="hidden" name="referer" value="<?php echo $_SERVER['REQUEST_URI']; ?>" />
  Email: <input type="text" name="email" />
  <input type="submit" value="Submit"
</form>

<?php
  $referer = isset($_POST['referer'])
    ? $_POST['referer']
    : 'index.php'; //Default value in case there is no referer
  header('Location: '.$referer);
  exit;
?>
