简单的PHP联系人表格：“提交”按钮不发送电子邮件

Question

我正在网站上使用联系表格，但它没有发送电子邮件，请有人能告诉我该代码有误吗？
此表单是从另一个有效的站点复制而来的，所以我不知道它在哪里失败。 我检查了语法，一切似乎都正常。

<?php 
/*
Template Name: Contact Page
*/

get_header();


$contact_show = true;

//If the form is submitted  
if(isset($_POST['submit'])) {  

 //Check to make sure that the name field is not empty  
 if(trim($_POST['contactname']) == '') {  
     $hasError = true;  
 } else {  
    $name = trim($_POST['contactname']);  
 }  
 //Check to make sure that the subject field is not empty  
if(trim($_POST['subject']) == '') {  
     $hasError = true;  
 } else {  
     $subject = trim($_POST['subject']);  
 }  

//Check to make sure sure that a valid email address is submitted  
if(trim($_POST['email']) == '')  {  
     $hasError = true;  
 } else if (!preg_match("/^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$/i",        trim($_POST['email']))) {  
     $hasError = true;
 } else {  
     $email = trim($_POST['email']);  
 }  

//Check to make sure comments were entered  
 if(trim($_POST['message']) == '') {  
     $hasError = true;  
} else {  
    if(function_exists('stripslashes')) {  
         $comments = stripslashes(trim($_POST['message']));  
   } else {  
        $comments = trim($_POST['message']);  
    }  
 }  

//If there is no error, send the email  
 if(!isset($hasError)) {  
    $contact_show = false;
    $emailTo = get_option('of_email_address'); 
    $body = "Name: $name \r\nEmail: $email \r\nSubject: $subject \r\nComments:\r\n $comments";          
    $headers = 'From: <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;  

    mail($emailTo, $subject, $body, $headers);  
    $emailSent = true;  
 }  
}

Answer 1

如果您从另一个运行正常的站点复制它，则表明PHP代码可以工作，并且实际上是服务器设置错误，因为那是您所做的更改（而不是PHP代码，我认为如果没有更改，则不会显示任何错误）以前在工作）。 确保这些设置正确：

http://php.net/manual/zh/mail.configuration.php

Answer 2

我检查了您的编码，因为没有错误，无法正常工作的原因可能是函数调用。

在您的编码中，存在多个函数调用。 检查所有功能是否存在以及该功能是否有错误。

Answer 3

同样，PHP看起来不错。 检查您的php.ini文件，并确保已将邮件功能配置为为PHP提供sendmail或SMTP连接的路径； 另外，请确保您的防火墙设置未阻止端口25（或配置的SMTP中继端口）
