PHPmailer:从foreach循环中排除输入字段

Question

我很高兴地使用https://github.com/PHPMailer/PHPMailer运行了一个联系人表单，最近添加了https://friendlycaptcha.com，以最大限度地减少机器人通过该表单发送的垃圾邮件数量。我喜欢没有用户交互的圆滑的实现。一旦您单击表单中的第一个输入字段，验证码就会被激活，并自动求解。不幸的是，验证码的解决方案(隐藏输入字段)向电子邮件中添加了一个我想要排除的巨大字符串。

如何告诉foreach循环不要在编写的邮件中包含frc-captcha-解决方案？

    private function compose_mail($post)
{
    $content = "The following message has been received via contact form:\n\n";
    foreach($post as $name=>$value)
    {
        $content .= ucwords($name).": \t";
        $content .= "$value\n\n";
    }
    $this->mailer->Body  = $content;
}

这是表单中的输入字段，生成的是长字符串。

<input name="frc-captcha-solution" class="frc-captcha-solution" type="hidden" value=".UNSTARTED">

我得到的一个例子是：

有很多方法可以做到这一点，但一种方法是当该名称出现在循环中时跳过它：

private function compose_mail($post)
{
    $content = "The following message has been received via contact form:\n\n";
    foreach($post as $name => $value) {
        if ($name !== 'frc-captcha-solution') {
            $content .= ucwords($name).": \t";
            $content .= "$value\n\n";
        }
    }
    $this->mailer->Body = $content;
}
