Developer Docs

The Developer Docs for CAOS Pro contain a list of available filters and actions for WordPress developers to add and/or manipulate various functions.

caos_pro_proxy_user_ip_address

Manipulate the IP address before it’s sent to the Google Analytics API.

For example, to (partially) mask the IP address, you could add the following filter either in a plugin or your child theme’s functions.php :

add_filter('caos_pro_proxy_user_ip_address', 'daan_anonymize_ip');
function daan_anonymize_ip($ip) {
    $octets = explode( '.', $ip );
    if ( empty( $octets ) ) {
	return $ip;
    }
    // To anonymize the last octet use this piece of code:
    $octets = $this->anonymize_one_octet( $octets );
    $last   = array_slice( $octets, -1, 1, true );
    $last_key = array_key_first( $last );
    $last[ $last_key ] = '0';
    $octets = array_replace( $octets, $last );
    // End of last octet anonymization
    // To anonymize the last two octets use this piece of code:
    $second_to_last     = array_slice( $octets, -2, 1, true );
    $second_to_last_key = array_key_first( $second_to_last );
    $second_to_last[ $second_to_last_key ] = '0';
    $last     = array_slice( $octets, -1, 1, true );
    $last_key = array_key_first( $last );
    $last[ $last_key ] = '0';
    $octets = array_replace( $octets, $second_to_last, $last );
    // End of last two octets anonymization.
    // To anonymize all octets:
    $octets = [ '1', '0', '0', '0' ];
    // End of all octets anonymization.
    return implode( '.', $octets );
