从javascript/Google recaptcha调用php文件

如果我的问题的答案是显而易见的，很多人表示歉意

我正在尝试将Google reCaptcha整合到我的网站中

这是我页面头部的javascript：

  var onSubmit = function(token) {
    $.ajax({
      type: 'POST',
      url: 'assets/php/contact.php',
      success: function(){
        alert('Thank you for your request ' + document.getElementById('name').value);
      }
    });
  };

reCaptcha是可见的，并且正在工作

上面的代码给出了“

成功：

”的结果，但没有使用对php文件的调用来处理表单

页面上的所有其他脚本都工作正常

下面是contact.php代码：

我已经对代码做了这些更改。然而，结果没有变化。以下是php文件的代码：

<?php
    //contact form submission code

  //Validate data on the form 
  // define variables and set to empty values
  $name = $email = $message = "";

  if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = contact_input($_POST["name"]);
    $email = contact_input($_POST["email"]);
    $message = contact_input($_POST["message"]);
  }

  function contact_input($data) {
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    return $data;
  }
  // if the url field is empty
if(isset($_POST['url']) && $_POST['url'] == ''){
  // put your email address here
  $youremail = 'my@email.co.uk';
  // prepare a "pretty" version of the message
  // Important: if you added any form fields to the HTML, you will need to add them here also
  $body = "Contact Form from Wilderness Canoe website just submitted:
  Name: $_POST[name]
  E-Mail: $_POST[email]
  Message: $_POST[message]";
  // Use the submitters email if they supplied one
  // (and it isn't trying to hack your form).
  // Otherwise send from your email address.
  if( $_POST['email'] && !preg_match( "/.+@.+\..+/i", $_POST['email']) ) {
    $headers = "From: $_POST[email]";
  } else {
    $headers = "From: $youremail";
  }
  // finally, send the message
  mail($youremail, 'Contact Form', $body, $headers );
}

?>

ajax请求不会在代码中发送任何表单数据。您应该像这样添加表单数据：

var onSubmit = function(token) {
  var formData = $("#yourFormId").serialize();

  $.ajax({
     type: 'POST',
     data: formData,
     url: 'assets/php/contact.php',
     success: function(){
       alert('Thank you for your request ' + document.getElementById('name').value);
     }
   });
};

你说表格没有处理是什么意思？在您的示例中，您没有向php脚本发送任何数据。表单数据由contact.php处理。我想让contact.php做这个处理。我试过使用POST和GET，但都不起作用。如果我根本不使用Google reCaptcha，那么表单“action=”“”调用contact.php，并且工作正常。在ajax调用中，您没有向post添加任何表单字段值。您能给我们看一下您的表单和contact.php文件的代码吗。@Selimhamud-编辑问题以显示代码。OK-消息似乎正在处理中。：）那很好。
