Question

我正在一个表格上，在它的核心，两个字段集：main和＆＃34;其他收件人＆＃34 ;;在＆＃34;其他收件人＆＃34;的最后fieldset，我有一个＆＃34;添加另一个收件人＆＃34;链接。

以下是谁需要：

主要收件人：一切

其他收件人＆＃34;其他收件人＆＃34;字段集;

后续收件人：各个字段集

到目前为止，我一直在看Documentation，但在那里运气不多，不是我预期的那样。

修改

我认为这还不清楚，所以我会更明确地说明背景是什么。我的form是一个注册，我们可以注册多个人;其中一个字段标有＆＃34;您的电子邮件＆＃34;。由于我们可以同时注册多个人，因此我需要复制fieldset包含＆＃34;您的电子邮件＆＃34;。

为了帮助澄清，想象一下我们正在为夏令营注册孩子。第一个fieldset是通用的，比如父母的结算信息，第二个fieldset是孩子的信息。父母需要能够填写单个form并动态添加与父母愿望一样多的子女。

在每个孩子的fieldset中，他们需要发送电子邮件，他们会收到与此孩子相关的信息，其中的电子邮件类似于：

Hello {children's name},

Answer 1

当你有一个这样的特定用例时，将功能强加到外围相关的插件中往往会导致沮丧。话虽这么说 - 有时候你会嫁给一个特定的插件或方法，只需要在它之上构建。

有了这个警告，我认为你应该从联系表格7的创建一个新的字段类型的角度来解决这个问题。这样你就可以控制渲染字段的HTML，数据验证等等。它可能也会提供数据库存储和发送提醒的启动点，稍后，正如您在另一个答案的评论中提到的那样。

以下是这种方法：

新的字段类型称为emailplus，您可以将其包含在以下格式中：

<div class="cf7-duplicable-recipients">
    <label>Main Recipient (required)</label>
    [emailplus emails]
    [submit "Sign Up"]
</div>

此外，我已将表单设置中的“邮件”面板下的收件人设置为[emails]。

如果将emailsplus字段设置为收件人，则该类将覆盖默认的wpcf7行为，并将邮件发送到email数组中的每个值，替换正文中的任何[电子邮件]占位符。基于每封电子邮件的消息。

emailplus字段类型在此处封装在一个类中，并且自由地进行了注释：

            true
        );
    }
}

$wpcf7DuplicableEmail = new WPCF7_Duplicable_Email();

并且，处理克隆的.js文件。它应该存在/path/to/your/theme/js/cf7-duplication.js'。

(function($) {
  $(document).ready(function() {
    var addEmailField = function(inputRow, container) {
      inputRow.find('input[type=email]').val('');

      var removeButton = $('<a href="#">&times;</a>')
        .click(function(e) {
          e.preventDefault();
          inputRow.remove();
        });

      inputRow.append(removeButton);
      inputRow.insertAfter(container.find('.emailplus-wrapper').last());
    }

    $.each($('[data-wpcf7-duplicable-email]'), function(i, el) {
      var container = $(el);
      var inputRow  = container.find('.emailplus-wrapper');
      var addButton = $('<a href="#">Add another email</a>');

      addButton.click(function(e) {
        e.preventDefault();
        var newEmailField = inputRow.clone();
        addEmailField(newEmailField, container);
      });

      container.append(addButton);
    });
  });
})(jQuery);

最后，但并非最不重要的一点是，如果您希望表单在淡出时有效并且电子邮件已经消失，请将其添加到“其他设置”面板中。

on_sent_ok: "jQuery('.cf7-duplicable-recipients').fadeOut();"

这种方法最适合CF7的 AJAX 提交。如果要扩展它以处理vanilla POST请求，您可以更新短代码处理程序以呈现多个<input>字段，您需要在无效提交时保留value attr。

Answer 2

选项 1）在设置菜单中的邮件点按下，单击邮件（2）后，在TO：字段中添加此行。如果父母的孩子少于所述的孩子数量，额外的电子邮件地址应该什么都不做。 [email]，[email]是基本格式。

[parents-email], [kid-email1], [kid-email2], [kid-email3], [kid-email4], [kid-email5], [kid-email6], [kid-email7]

选项2）在“收件人：”字段中，只需放置1个电子邮件地址，例如父母。并在附加标题中：将代码放在

下面

CC: [kid-email1], [kid-email2], [kid-email3], [kid-email4], [kid-email5], [kid-email6], [kid-email7]

或

BCC: [kid-email1], [kid-email2], [kid-email3], [kid-email4], [kid-email5], [kid-email6], [kid-email7]

可能出现的问题：许多主机阻止此类内容以防止垃圾邮件。如果这些不起作用，那么可能就是这种情况。您需要联系您的托管服务提供商以了解删除该阻止。

Answer 3

联系表单7只有一个收件人字段，但是您可以在该字段中输入多个以逗号分隔的电子邮件地址，例如＆＃34; email1 @ domain.com，email2 @ domain.com，email3 @ domain.com＆＃34 ;。

因此，对于您的情况，使用JavaScript动态添加多个重复的收件人字段，最后在表单上提交编写JavaScript函数以连接所有收件人电子邮件地址，然后将其保留在主收件人字段中并提交表单。希望你明白我的意思。
