Stop WordPress Pinging Itself When you Link Internally

WordPress Snippets

I find it very annoying when I place a link on one post, to another post and then I get a comment notification within the WordPress admin informing me there has been a ping/trackback to one of my posts. With the below snippet you can stop this happening (place in functions.php file):

//remove pings to self
function no_self_ping( &$links ) {
    $home = get_option( 'home' );
    foreach ( $links as $l => $link )
        if ( 0 === strpos( $link, $home ) )
            unset($links[$l]);
}
add_action( 'pre_ping', 'no_self_ping' );

//remove pings to self

function no_self_ping( &$links ) {

$home = get_option( 'home' );

foreach ( $links as $l => $link )

if ( 0 === strpos( $link, $home ) )

unset($links[$l]);

}

add_action( 'pre_ping', 'no_self_ping' );
