Description

Retrieve referer from '_wp_http_referer', HTTP referer, or current page respectively.

Usage

<?php wp_get_referer(); ?>

Parameters

None.

Return Values

(string|boolean) 

False on failure. Referer URL on success. If page "refered" (form posted) to itself, returns false (because $_SERVER['HTTP_REFERER'] == $_REQUEST['_wp_http_referer'])

Examples

<?php 
if ( wp_get_referer() )
{
    wp_safe_redirect( wp_get_referer() );
}
else
{
    wp_safe_redirect( get_home_url() );
}
?>

Notes

• HTTP referer is a server variable. 'referer' is deliberately misspelled.
