how to implement a Send me a copy of message in another languages

Hi Takayuki,

The English version of Send me a copy of message worked just once. Now it doesn’t work anymore. When I add the code to functions.php file I cannot access to the wp anymore.. So I’ve to delete the code to get the wp working again..

Regarding your answer I did create 2 forms in the desired languages. I also filled the Mail(2) content. I used Polylang not to create the forms, but to the website pages, I mean to have a version of each page in the other two languages.

Thanks.

I am using your code on functions.php

add_filter( 'wpcf7_additional_mail', 'my_wpcf7_use_mail_2_or_not', 10, 2 );

function my_wpcf7_use_mail_2_or_not( $additional_mail, $cf ) {
	if ( "Send me a copy of this message" != $cf->posted_data['send_c'][0] )
		$additional_mail = array();

	return $additional_mail;
}

also I added the following in each form:

[checkbox send_c default:0 "Send me a copy of this message"]
