No specific form

Hi,

I’m using the code below for a specific form(18), not to send emails. With the upgrade to version 4.9 and the code has stopped working.

function wpcf7_no_send($cf7) {
$wpcf = WPCF7_ContactForm::get_current();
if ($wpcf->id == 18) {
$wpcf->skip_mail = true;
}
return $wpcf;
}
add_action(“wpcf7_before_send_mail”, “wpcf7_no_send”);

Could you tell me what I’m doing wrong?

Thanks!

Pedro.
