这与PHPMailer无关-该错误发生在任何PHPMailer代码运行之前

您正在
$\u POST
数组中查找名为
g-recaptcha-response
的值,但该值不存在,因此出现错误。您没有具有该名称的输入元素,这就是为什么
$\u POST
中缺少该元素的原因。可能是google代码从JS动态添加了它,但在您发布的内容中没有证据表明它这样做。我建议你多读一些recaptcha文档


这不是一个特别的问题,但是您运行的是非常旧版本的PHPMailer,并且您的代码基于一个过时的示例。

您没有将令牌传递给请求。您必须在表单中设置令牌值。 你可以这样做

 grecaptcha.ready(function() {
    grecaptcha.execute("KEY_VALUE", {action: 'form'})
    .then(function(token) {
       localStorage.setItem('recaptcha_token', token)
       $('form').prepend('<input type="hidden" name="g-recaptcha-response" value="' + token + '">');
     });
  });
grecaptcha.ready(函数(){
execute(“KEY_VALUE”,{action:'form'})
.then(功能(令牌){
setItem('recaptcha_标记',标记)
$('form')。前缀(“”);
});
});
    <form action="form.php" method="POST" class="contact__form g-recaptcha" 
    id="form" data-sitekey="6LdvpmIUAAAAABEO5KGWX1KsIJgPQnZyAJep4lkw">
   <div class="form__div">

     <label for="name">Name </label>
     <input type="text" name="name" id="name" class="input input__name" required/>

   </div>

   <div class="form__div">

     <label for="email">E-mail </label>
     <input type="email" name="email" id="email" class="input input__email " required/>

   </div>

   <div class="form__div">

     <label>Message </label>
     <textarea rows="5" aria-label="Write something" name="message" class="input input__mess" placeholder="Write..." minlength="10" maxlength="1000" required></textarea>

   </div>

 <button name="submit" type="submit" id="submit" class="form__button">Wyślij</button>

 </form>
 grecaptcha.ready(function() {
    grecaptcha.execute("KEY_VALUE", {action: 'form'})
    .then(function(token) {
       localStorage.setItem('recaptcha_token', token)
       $('form').prepend('<input type="hidden" name="g-recaptcha-response" value="' + token + '">');
     });
  });
