简单的PHP联系表格:提交按钮不发送电子邮件



我正在使用网站上的联系表格,但它没有发送电子邮件,请谁能告诉我这个代码哪里有问题?
此表单是从另一个有效的站点复制的,因此我无法理解它在哪里失败。 我已经检查了语法,一切似乎都很好。

<?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 rnEmail: $email rnSubject: $subject rnComments:rn $comments";          
    $headers = 'From: <'.$emailTo.'>' . "rn" . 'Reply-To: ' . $email;  
    mail($emailTo, $subject, $body, $headers);  
    $emailSent = true;  
 }

如果您从另一个确实有效的站点复制它,这表明 PHP 代码有效,并且实际上是您的服务器设置是错误的,因为这是您更改的(而不是 PHP 代码,我认为如果它以前工作,则不会显示任何错误)。确保这些设置正确:

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

我检查了您的编码,因为没有错误,并且不工作的原因是函数调用可能是。

在您的编码中,存在多个函数调用。检查所有函数是否存在,以及该函数中是否有任何错误。

同样,PHP 看起来不错;检查您的 php.ini 文件,并确保邮件功能配置为为 PHP 提供发送邮件的路径或 SMTP 连接;此外,请确保您的防火墙设置没有阻止端口 25(或您配置的 SMTP 中继端口)
