Question

我目前正在使用运行Apache和PHP 5.6的网络服务器从头创建一个个人网站。我制作了框架，一些页面和一些CSS。我目前在将Google的reCaptcha v2集成到我的联系表单时遇到了问题。我能够通过HTML将它集成到表单中，我的AJAX脚本工作正常，但我不能为我的生活弄清楚如何将captcha检查正确地集成到我的PHP脚本中。我想要喜欢PHP，我将不得不更多地使用它，但尝试让它工作非常令人沮丧。

这个表单在没有catcha集成的情况下工作得很好，但是当我将这些更改引入PHP脚本时，它无法完成并且不会发送消息。我一直在追查确切的问题，但无法弄明白。我很乐意使用JS alert（）来存根脚本的不同部分，但由于它是PHP我不能这样做：c我还使用了一些验证器来确保PHP的语法是正确的。我的IDE中没有错误。

任何人都可以通过以下PHP表单脚本看到任何荒谬的问题吗？

  $(form).submit(function(e) {

    var formData = $(form).serialize();
    // Submit the form using AJAX.
    $.ajax({

        data: formData
      })
      .done(function(response) {

        // Set the message text.
        $('#alert-form-success-text').text(response);
        $('#alert-form-success').css({

        if (data.responseText !== '') {
          $('#alert-form-fail-text').text(data.responseText);
        } else {
          $('#alert-form-fail-text').text('An internal error occured and your message could not be sent.');
        }
      });

  });

});

该问题仅涉及reCaptcha集成，脚本获取POST信息和电子邮件的能力很好。我认为这个问题已经局限于

启动的方法链

$validation = sendCaptchaResponse();

如果您有任何疑问，请随时提出。这是包含以下格式的页面：https://chillstice.com/contact

Answer 1

PHP文件中的fileGetContentsCurl（）函数作为'file_get_contents_curl（）'运行

修复此错字并使方法以一致的名称解决此问题。我确定希望我的IDE或调试工具能帮助我修复这一（1）错误，但这对你来说就是PHP。

我要感谢Karlo Kokkak暗示我的错字。

完成更改后，整个脚本按预期工作。

使用reCaptcha v2的PHP和AJAX表单无法运行PHP脚本
