发送电子邮件不适用于引导程序[重复]

Question

当您使用boothstrap 填写联系我们表格时，我正在尝试发送电子邮件。我收到一封电子邮件，但它的空电子邮件已填写，没有任何信息。请帮助我在哪里出错。

这是我的 PHP。

<?
if(isset($_POST['sendemail'])) {     

// EDIT THE 2 LINES BELOW AS REQUIRED

$email_to = "contact.hanif@gmail.com";

$email_subject = "General Inquery";
$name = $_POST['name']; 
$email = $_POST['email']; 
$subject =$_POST['subject']; 
$message = $_POST['message'];      

function clean_string($string) {

  $bad = array("content-type","bcc:","to:","cc:","href");

  return str_replace($bad,"",$string);

}
$email_message .= "First Name: ".clean_string($name)."\n";    

$email_message .= "Email: ".clean_string($email_from)."\n";

$email_message .= "subject: ".clean_string($subject)."\n";

$email_message .= "message: ".clean_string($message)."\n";

$headers = 'From: '.$email_from."\r\n".

   'Reply-To: '.$email_from."\r\n" .

  'X-Mailer: PHP/' . phpversion();

   @mail($email_to, $email_subject, $email_message, $headers);  

?>

我不认为，这是你的完整代码，但我可以看到你从未设置过 $_POST['sendemail'] 所以if(isset($_POST['sendemail'])) { 永远不会是真的。

看下面的代码，我做了3个cmets。

<?php
// 1. -------------↓ Change sendemail to submit
if(isset($_POST['submit'])) {         

// EDIT THE 2 LINES BELOW AS REQUIRED

$email_to = "contact.hanif@gmail.com";

$email_subject = "General Inquery";
$name = $_POST['name']; 
$email = $_POST['email']; 
$subject =$_POST['subject']; 
$message = $_POST['message'];      

function clean_string($string) {

  $bad = array("content-type","bcc:","to:","cc:","href");

  return str_replace($bad,"",$string);

}

// 2. --↓  Add $email_message = '';
$email_message = '';    
$email_message .= "First Name: ".clean_string($name)."\n";

// 3. -------------------------------------↓   Change $email_from to $email     
$email_message .= "Email: ".clean_string($email)."\n";    
$email_message .= "subject: ".clean_string($subject)."\n";    
$email_message .= "message: ".clean_string($message)."\n";    
echo "message: " . $email_message . "<br>";
}

?>
