    $email   = isset( $_POST[ $wpide_cf7_email_field ] ) ? strtolower( trim( (string) wp_unslash( $_POST[ $wpide_cf7_email_field ] ) ) ) : '';
    $confirm = isset( $_POST[ $wpide_cf7_confirm_field ] ) ? strtolower( trim( (string) wp_unslash( $_POST[ $wpide_cf7_confirm_field ] ) ) ) : '';

    if ( $email !== $confirm ) {

};

add_filter( 'wpcf7_validate_email', $wpide_cf7_confirm_check, 20, 2 );
add_filter( 'wpcf7_validate_email*', $wpide_cf7_confirm_check, 20, 2 );
