    1. Override the comment_content

    This example overrides the value in the “comment_content” Akismet field so that is is pulled from another field. (field ID: 1).

    add_filter( 'gform_akismet_fields', 'set_akismet_fields', 10, 3 );
    function set_akismet_fields( $akismet_fields, $form, $entry ) {
    $akismet_fields['comment_content'] = rgar( $entry, '1' );
    return $akismet_fields;

    2. Provide the IP address

    This example shows how you can pass the IP address to Akismet when it has been removed from the entry using the gform_ip_address filter.

    add_filter( 'gform_akismet_fields', 'set_akismet_fields', 10, 3 );
    function set_akismet_fields( $akismet_fields, $form, $entry ) {
    remove_filter( 'gform_ip_address', '__return_empty_string' );
    $ip = GFFormsModel::get_ip();
    $akismet_fields['comment_author_IP'] = $ip;
    $akismet_fields['user_ip'] = preg_replace( '/[^0-9., ]/', '', $ip );
    return $akismet_fields;
