Back to previous page with header( "Location: " ); in PHP

try:

header('Location: ' . $_SERVER['HTTP_REFERER']);

Note that this may not work with secure pages (HTTPS) and it's a pretty bad idea overall as the header can be hijacked, sending the user to some other destination. The header may not even be sent by the browser.

Ideally, you will want to either:

• Append the return address to the request as a query variable (eg. ?back=/list)
• Define a return page in your code (ie. all successful form submissions redirect to the listing page)
• Provide the user the option of where they want to go next (eg. Save and continue editing or just Save)

Its so simple just use this

header("location:javascript://history.go(-1)");

Its working fine for me

You have to save that location somehow.

Say it's a POST form, just put the current location in a hidden field and then use it in the header() Location.

Just a little addition: I believe it's a common and known thing to add exit; after the header function in case we don't want the rest of the code to load or execute...

header('Location: ' . $_SERVER['HTTP_REFERER']);
exit;

Just try this in Javascript:

 $previous = "javascript:history.go(-1)";

Or you can try it in PHP:

if(isset($_SERVER['HTTP_REFERER'])) {
    $previous = $_SERVER['HTTP_REFERER'];
}
