与谷歌reCaptcha自定义联系表格

Question

试图实施与谷歌reCaptcha自定义编码的联系表格，但似乎没有采取。这是使用WordPress的（不希望使用插件'验证回来了“谢谢张贴评论”。不要从表格中的电子邮件/消息，检查我的垃圾邮件等。任何帮助将不胜感激。如下：

<div class="contact_form"> 
     <h1>Contact Form</h1> 
     <form id="comment_form" action="" method="post"> 
      <p>Your Name (required) <br /> 
      <input type="text" name="cf-name" placeholder="type your name" pattern="[a-zA-Z0-9 ]+" size="40" /> 
      </p> 
      <p>Your Email (required) <br /> 
      <input type ="email" name="cf-email" placeholder="type your email" size ="40"><br> 
      </p> 
      <p>Subject (required)<br /> 
      <input type ="text" name="cf-subject" placeholder="type your subject" size ="40"><br> 
      </p> 
      <p>Your Message<br /> 
      <textarea rows="10" cols="35" name="cf-message"></textarea> 
      </p> 
      <div class="g-recaptcha" data-sitekey="SITEKEYHERE"></div> 
      <input type="submit" name="submit" value="Post Comment"> 
     </form> 
     </div> 

而且我的PHP来发送电子邮件，并检查验证码：

<?php 

    // if the submit button is clicked, send the email 
    if (isset($_POST['cf-submitted'])) { 

     // sanitize form values 
     $name = sanitize_text_field($_POST["cf-name"]); 
     $email = sanitize_email($_POST["cf-email"]); 
     $subject = sanitize_text_field($_POST["cf-subject"]); 
     $message = esc_textarea($_POST["cf-message"]); 

     // get the blog administrator's email address 
     $to = "my@email.here"; 

     $headers = "From: $name <$email>" . "\r\n"; 

     // If email has been process for sending, display a success message 
     if (wp_mail($to, $subject, $message, $headers)) { 
      echo '<div>'; 
      echo '<p>Thanks for contacting me, expect a response soon.</p>'; 
      echo "$to"; 
      echo '</div>'; 
     } else { 
      echo 'An unexpected error occurred'; 
      } 
    }?> 


    <?php 

     $name;$email;$subject;$message;$captcha; 
     if(isset($_POST['cf-name'])){ 
      $email=$_POST['cf-name']; 
     }if(isset($_POST['cf-email'])){ 
      $email=$_POST['cf-email']; 
     }if(isset($_POST['cf-subject'])){ 
      $email=$_POST['cf-subject']; 
     }if(isset($_POST['cf-message'])){ 
      $email=$_POST['cf-message']; 
     }if(isset($_POST['g-recaptcha-response'])){ 
      $captcha=$_POST['g-recaptcha-response']; 
     } 
     if(!$captcha){ 
      echo '<h2>Please check the the captcha form.</h2>'; 
      exit; 
     } 
     $response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=SECRETKEYHERE".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']); 
     if($response.success==false) 
     { 
      echo '<h2>spam</h2>'; 
     }else 
     { 
      echo '<h2>Thanks for posting comment.</h2>'; 
     } 
?>

你的邮件代码是在你验证您的验证码之前触发

试着走动代码：

<?php 

    $name;$email;$subject;$message;$captcha; 
    if(isset($_POST['cf-name'])){ 
     $email=$_POST['cf-name']; 
    }if(isset($_POST['cf-email'])){ 
     $email=$_POST['cf-email']; 
    }if(isset($_POST['cf-subject'])){ 
     $email=$_POST['cf-subject']; 
    }if(isset($_POST['cf-message'])){ 
     $email=$_POST['cf-message']; 
    }if(isset($_POST['g-recaptcha-response'])){ 
     $captcha=$_POST['g-recaptcha-response']; 
    } 
    if(!$captcha){ 
     echo '<h2>Please check the the captcha form.</h2>'; 
     exit; 
    } 
    $response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=SECRETKEYHERE".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']); 
    if($response.success==false){ 
     echo '<h2>spam</h2>'; 
    }else{ 
     // sanitize form values 
     $name = sanitize_text_field($_POST["cf-name"]); 
     $email = sanitize_email($_POST["cf-email"]); 
     $subject = sanitize_text_field($_POST["cf-subject"]); 
     $message = esc_textarea($_POST["cf-message"]); 

     // get the blog administrator's email address 
     $to = "my@email.here"; 

     $headers = "From: $name <$email>" . "\r\n"; 

     // If email has been process for sending, display a success message 
     if (wp_mail($to, $subject, $message, $headers)) { 
      echo '<div>'; 
      echo '<p>Thanks for contacting me, expect a response soon.</p>'; 
      echo "$to"; 
      echo '</div>'; 
     } else { 
      echo 'An unexpected error occurred'; 
     }   

    } 
?> 

我在手机上点击了这个，所以你可以整理这个代码了很多。 但逻辑应该是对的。
