當使用PHP郵件時，變量不會被髮送

Question

我將以下代碼用作php文件，同時我將信息發佈爲HTML文件，用戶在填寫數據後單擊該按鈕。目前在測試變量（$ name，$ email，$ subject，$ message）不會在電子郵件內容中發送，除了其他字符串。

的index.html

<form id="main-contact-form" class="contact-form" name="contact-form" method="post" action="sendemail.php"> 
     <div class="form-group"> 
      <input type="text" name='name' class="form-control" required="required" placeholder="Name"/> 
     </div> 
     <div class="form-group"> 
      <input type="email" name="email" class="form-control" required="required" placeholder="Email ID"> 
     </div> 
     <div class="form-group"> 
      <textarea name="subject" id="message" required="required" class="form-control" rows="4" placeholder="Enter your message"></textarea> 
     </div> 
     <div class="form-group"> 
      <textarea name="message" id="message" required="required" class="form-control" rows="4" placeholder="Enter your message"></textarea> 
     </div> 
     <div class="form-group"> 
      <button type="submit" class="btn btn-primary pull-right">Send</button> 
     </div> 
    </form> 

sendmail.php

$name = @trim(stripslashes($_POST['name'])); 
$email = @trim(stripslashes($_POST['email'])); 
$subject = @trim(stripslashes($_POST['subject'])); 
$message = @trim(stripslashes($_POST['message'])); 

$email_from = $email; 
$email_to = 'dhananjayan322@gmail.com';//replace with your email 

$body = 'Name: ' . $name . "\n\n" . 'Email: ' . $email . "\n\n" .' Subject: ' . $subject . "\n\n" . 'Message: ' . $message; 

$success = @mail($email_to, $subject, $body, 'From: <'.$email_from.'>'); 

輸出

Answer 1

必須受到前添加一個單引號：

$name = @trim(stripslashes($_POST['name'])); 
$email = @trim(stripslashes($_POST['email'])); 
$subject = @trim(stripslashes($_POST['subject'])); 
$message = @trim(stripslashes($_POST['message'])); 

$email_from = $email; 
$email_to = 'dhananjayan322@gmail.com'; // replace with your email 

$body = 'Name: ' . $name . "\n\n" . 'Email: ' . $email . "\n\n" . 'Subject: ' . $subject . "\n\n" . 'Message: ' . $message; 

$success = @mail($email_to, $subject, $body, 'From: <'.$email_from.'>'); 

echo json_encode($status); 
die;
