聯繫表格在PHP中發送空白數據

Question

我最近爲我的朋友做了一個網站，幷包含一個使用PHP的聯繫表。當人發送電子郵件時，數據不通過電子郵件發送。

這是網站

<article class="grid_8"> 
    <div class="indent-left"> 
     <h3 class="p1">Contact us</h3> 
     <form id="contact-form" method="post" name="myemailform" action="contact_form.php"> 
      <fieldset> 
       <label><span class="text-form">Name:</span><input name="name" type="text" required /></label> 
       <label><span class="text-form">Email:</span><input name="email" type="text" required /></label>        
       <label><span class="text-form">Phone:</span><input name="phone" type="text" /></label>        
       <div class="wrapper"> 
        <div class="text-form">Message:</div> 
        <div class="extra-wrap"> 
         <textarea name="message" required></textarea> 
         <div class="clear"></div> 
         <div class="buttons"> 
          <input type="submit" value="Submit" class="button"> 
         </div> 
        </div> 
       </div>        
      </fieldset>      
     </form> 
    </div> 
</article> 

代碼這是PHP

<?php 

$name = $_POST['name']; 
$message = $_POST['message']; 
$phone = $_POST['phone']; 
$email_from = $_POST['email']; 
$email_subject = $_POST["New Message From www.chevroncreativesolutions.com"]; 
$email_body = $_POST["You have received a new message from $name.\n". 
        "Here is the message:\n $message.\n You Can call me on $phone.\n"]. 

$to = "matthias.mccarthy@gmail.com"; 
$headers = "From: $email_from \r\n"; 
$contact_form=mail($to,$email_subject,$email_body,$headers); 

if($contact_form) { 
    echo "Message has been sent."; 
    echo "<form><input type='button' value='Return back' onclick='history.back();'></form>"; 
} else { 
    echo "Error In sending your message"; 
    echo "<form><input type='button' value='Return back' onclick='history.back();'></form>"; 
} 

Answer 1

你$headers = "From: $email_from \r\n";必須"From: $EmailFrom" . "\r\n"的代碼。

你缺少一個.

Answer 2

你設置你的$email_subject和$email_body值設置爲undefined $_POST值：

$email_subject = $_POST["New Message From www.chevroncreativesolutions.com"]; 
$email_body = $_POST["You have received a new message from $name.\n". 
        "Here is the message:\n $message.\n You Can call me on $phone.\n"]; 

相反，降$_POST[]部分：

$email_subject = "New Message From www.chevroncreativesolutions.com"; 
$email_body = "You have received a new message from $name.\n". 
       "Here is the message:\n $message.\n You Can call me on $phone.\n"; 

此外，但與您的問題無關，您需要清理$email_from以防止標題注入：

$email_from = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL); 
if ($email_from === false) { 
    echo 'error, invalid email'; 
}
