如何以當前PHP電子郵件的形式實現reCAPTCHA

Question

我是PHP新手，但知道我的HTML解決方案。我被要求在我們網站的PHP聯繫人電子郵件表格中實施reCaptcha表單。我快空了。我已經註冊並擁有我的網站密鑰和密鑰，但不知道如何將其整合到我們的表單中。

這是我們網站的PHP形式：

<?php 

if(!$_POST) exit; 

// Email address verification, do not edit. 
function isEmail($email) { 
    return(preg_match("/^[-_.[:alnum:]]+@((([[:alnum:]]|[[:alnum:]][[:alnum:]-]*[[:alnum:]])\.)+(ad|ae|aero|af|ag|ai|al|am|an|ao|aq|ar|arpa|as|at|au|aw|az|ba|bb|bd|be|bf|bg|bh|bi|biz|bj|bm|bn|bo|br|bs|bt|bv|bw|by|bz|ca|cc|cd|cf|cg|ch|ci|ck|cl|cm|cn|co|com|coop|cr|cs|cu|cv|cx|cy|cz|de|dj|dk|dm|do|dz|ec|edu|ee|eg|eh|er|es|et|eu|fi|fj|fk|fm|fo|fr|ga|gb|gd|ge|gf|gh|gi|gl|gm|gn|gov|gp|gq|gr|gs|gt|gu|gw|gy|hk|hm|hn|hr|ht|hu|id|ie|il|in|info|int|io|iq|ir|is|it|jm|jo|jp|ke|kg|kh|ki|km|kn|kp|kr|kw|ky|kz|la|lb|lc|li|lk|lr|ls|lt|lu|lv|ly|ma|mc|md|me|mg|mh|mil|mk|ml|mm|mn|mo|mp|mq|mr|ms|mt|mu|museum|mv|mw|mx|my|mz|na|name|nc|ne|net|nf|ng|ni|nl|no|np|nr|nt|nu|nz|om|org|pa|pe|pf|pg|ph|pk|pl|pm|pn|pr|pro|ps|pt|pw|py|qa|re|ro|ru|rw|sa|sb|sc|sd|se|sg|sh|si|sj|sk|sl|sm|sn|so|sr|st|su|sv|sy|sz|tc|td|tf|tg|th|tj|tk|tm|tn|to|tp|tr|tt|tv|tw|tz|ua|ug|uk|um|us|uy|uz|va|vc|ve|vg|vi|vn|vu|wf|ws|ye|yt|yu|za|zm|zw)$|(([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5])\.){3}([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5]))$/i",$email)); 
} 

if (!defined("PHP_EOL")) define("PHP_EOL", "\r\n"); 

$name  = $_POST['name']; 
$email = $_POST['email']; 
$comments = $_POST['comments']; 

if(trim($name) == '') { 
    echo '<div class="error_message">Please enter your name.</div>'; 
    exit(); 
} else if(trim($email) == '') { 
    echo '<div class="error_message">Please enter a valid email address.</div>'; 
    exit(); 
} else if(!isEmail($email)) { 
    echo '<div class="error_message">You have entered an invalid e-mail address, try again.</div>'; 
    exit(); 
} 

if(trim($comments) == '') { 
    echo '<div class="error_message">Please enter your message.</div>'; 
    exit(); 
} 

if(get_magic_quotes_gpc()) { 
    $comments = stripslashes($comments); 
} 


// Configuration option. 
// Enter the email address that you want to emails to be sent to. 
// Example $address = "yourname@yourdomain.com"; 

$address = "contact@########.com"; 


// Configuration option. 
// i.e. The standard subject will appear as, "You've been contacted by John Doe." 

// Example, $e_subject = '$name . ' has contacted you via Your Website.'; 

$e_subject = 'You\'ve been contacted by ' . $name . '.'; 


// Configuration option. 
// You can change this if you feel that you need to. 
// Developers, you may wish to add more fields to the form, in which case you must be sure to add them here. 

$e_body = "You have been contacted by $name from your website, their message is as follows." . PHP_EOL . PHP_EOL; 
$e_content = "\"$comments\"" . PHP_EOL . PHP_EOL; 
$e_reply = "You can contact $name by email, $email or by phone $phone"; 

$msg = wordwrap($e_body . $e_content . $e_reply, 70); 

$headers = "From: $email" . PHP_EOL; 
$headers .= "Reply-To: $email" . PHP_EOL; 
$headers .= "MIME-Version: 1.0" . PHP_EOL; 
$headers .= "Content-type: text/plain; charset=utf-8" . PHP_EOL; 
$headers .= "Content-Transfer-Encoding: quoted-printable" . PHP_EOL; 

if(mail($address, $e_subject, $msg, $headers)) { 

    // Email has sent successfully, echo a success page. 

    echo "<fieldset>"; 
    echo "<div id='success_page'>"; 
    echo "<h2>Email Sent Successfully.</h2>"; 
    echo "<p>Thank you <strong>$name</strong>, your message has been sent to us.</p>"; 
    echo "</div>"; 
    echo "</fieldset>"; 

} else { 

    echo 'ERROR!'; 

} 

任何幫助表示讚賞。謝謝！

首先，作爲你的表單元素的一部分，包括驗證碼：

<?php 
require_once("location/of/recaptchalib.php"); 
    $publickey = "yourPublicKeyGoesHere"; 
    echo recaptcha_get_html($publickey); 
?> 

在send_email.php文件，你可以這樣做：

<?php 

    session_start(); 

    require_once("location/of/recaptchalib.php"); 
    $timezone = "Asia/Kuwait"; 
     if(function_exists('date_default_timezone_set')) date_default_timezone_set($timezone); 

    $privatekey = "YourPrivateKey"; 

    $resp = recaptcha_check_answer ($privatekey, 
       $_SERVER["REMOTE_ADDR"], 
       $_POST["recaptcha_challenge_field"], 
       $_POST["recaptcha_response_field"] 
       ); 

    if (!$resp->is_valid) { 
     // What happens when the CAPTCHA was entered incorrectly 
     die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." . 
      "(reCAPTCHA said: " . $resp->error . ")"); 
    } 

    else { 
     $sender_name = $_POST['sender_name']; 
     $sender_email = $_POST['sender_email']; 
     $query_type  = $_POST['query_type']; 
     $ip    = $_SERVER["REMOTE_ADDR"]; 
     $date   = date("d M Y H:i:s"); 
     $sender_message = "Thank You for your message, ".$sender_name."\r\n"."Message was sent from ".$ip."on ".$date."\r\n".$_POST['sender_message']; 

     $headers  = "From: Your Website" . "\r\n" . 
          "BCC: you@yourwebsite.com"; 
     mail($sender_email,'Email from yourwebsite guest',$sender_message,$headers); 

     echo "Message Sent!"; 
    } 
?> 

這個工作對我來說，和形式看起來是這樣的：

我希望這有助於。
