Filters the document title before it is generated.

Passing a non-empty value will short-circuit wp_get_document_title(), returning that value instead.

Usage

add_filter( 'pre_get_document_title', 'filter_function_name_3141' );
function filter_function_name_3141( $title ){
	// filter...

	return $title;
}

$title(string)

The document title.
Default: empty string
