wp_get_raw_referer() │ WP 4.5.0

Gets the referer (referer) URL. A wrapper for $_SERVER['HTTP_REFERER'].

The function first checks for the presence of the referer in $_REQUEST['_wp_http_referer'], if it is not there, it takes the referer as usual from $_SERVER['HTTP_REFERER'].

Use wp_get_referer() when you need to get only the internal referer link - a referer link only from the current site (if not from the current site, then get an empty string instead of the URL)

Used By: wp_get_referer()

No Hooks.

Returns

String|false. URL — if the referer exists. false — if there is no referer.

Usage

$referer = wp_get_raw_referer();

Examples

#1 Check if there is a referrer link

Suppose we were on page http://example.com/foo and went to page http://example.com/bar where the following code is triggered:

$referer = wp_get_raw_referer();

if( $referer ){
	echo $referer;
}

On the screen we will see the URL of the page we came from: http://example.com/foo.
