Wordpress Worpress联系表7 wpcf7发送邮件前密件抄送字段

（对不起我的英语）我刚开始使用wordpress，这是一个简单的代码，在发送邮件之前在wpcf7的密件抄送字段中写电子邮件？非常感谢。 （请注意，我必须在联系人表格7中使用wpcf7_发送邮件之前不发送邮件选项卡）

你可以试试这个

此挂钩（wpcf7_before_send_mail）将在发送电子邮件之前运行，因此您还可以修改当前表单数据

为什么不使用

wpcf7\u邮件\u组件

过滤器？

add_action('wpcf7_before_send_mail','dynamic_addcc');
   function dynamic_addcc($WPCF7_ContactForm){

// Check contact form id.
if (33 == $WPCF7_ContactForm->id()) {

    $currentformInstance  = WPCF7_ContactForm::get_current();
    $contactformsubmition = WPCF7_Submission::get_instance();

    if ($contactformsubmition) {

        $cc_email = array();

        /* -------------- */
        // replace with your email field's names
        if(is_email($_POST['friend1-email'])){
            array_push($cc_email, $_POST['friend1-email']);
        }
        if(is_email($_POST['friend2-email'])){
            array_push($cc_email, $_POST['friend2-email']);
        }
        /* -------------- */

        // saparate all emails by comma.
        $cclist = implode(', ',$cc_email);

        $data = $contactformsubmition->get_posted_data();

        if (empty($data))
            return;

        $mail = $currentformInstance->prop('mail');

        if(!empty($cclist)){
            $mail['additional_headers'] = "Cc: $cclist";
        }

        // Save the email body
        $currentformInstance->set_properties(array(
            "mail" => $mail
        ));

        // return current cf7 instance
        return $currentformInstance;
    } 
}
}
