[Solved] Browser Language shortcode for Localized response

For language shorcode, i wanted to share the changed code to support opensource work.

here is the function change in special-mail-tags.php

It allows you to use [_lang] tag in email, so output browser accepted language, used in localized response.

function wpcf7_special_mail_tag( $output, $name ) {

// For backwards compat.
$name = preg_replace( ‘/^wpcf7\./’, ‘_’, $name );

if ( ‘_remote_ip’ == $name )
$output = preg_replace( ‘/[^0-9a-f.:, ]/’, ”, $_SERVER[‘REMOTE_ADDR’] );

elseif ( ‘_url’ == $name ) {
$url = untrailingslashit( home_url() );
$url = preg_replace( ‘%(?<!:|/)/.*$%’, ”, $url );
$url .= wpcf7_get_request_uri();
$output = esc_url( $url );
}

elseif ( ‘_date’ == $name )
$output = date_i18n( get_option( ‘date_format’ ) );

elseif ( ‘_time’ == $name )
$output = date_i18n( get_option( ‘time_format’ ) );

elseif ( ‘_lang’ == $name ) {
$code = substr($_SERVER[‘HTTP_ACCEPT_LANGUAGE’],0,2);
