使用PHP发送带附件的电子邮件

问题描述：

大家好，

我正在使用PHP从联系表单发送附件中的电子邮件。

我有2个问题：

1-它在localhost上不起作用。

2-在托管网站的服务器上，只有在发送到GMAIL帐户但没有发送附件时才有效。

网站非常简单，只是HTML页面，这是我需要使用服务器代码发送电子邮件的唯一页面。

请告知我做错了什么

谢谢

我尝试过：

HTML code：

Hi All,

I'm using PHP to send an email from contact form with attachment.
I have 2 problems:
1- it doesn't work on localhost.
2- on the server where the website is hosted it worked only when sending to GMAIL account but without sending the attachment.
The website is very simple just HTML pages, this is the only page that I need to use server code to send an email.

Please advise what I'm doing wrong
Thank you

HTML code:

<pre><!DOCTYPE html>
<html>
<head>
<link rel='stylesheet' type='text/css' href='sendEmail.css'/>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
 
<script type='text/javascript' src='validateEmail.js'></script>
</head>
<body>
    <form name="contactform" class="contactform" method="post" onsubmit="return validateForm()"  action="sendEmail.php">
        <label>Sender Email:</label>
        <input type="text" id="semail" name="semail" />
        <label>Recipient Email:</label>
        <input type="text" id="remail" name="remail" value="" />
        <label for="Subject">Subject:</label>
        <input type="text" name="Subject" id="Subject" />
        <label for="Attachment">Attachment:</label>
        <input type="file" name="attach1" id="attach1" />
        <label for="Message">Message:</label><br />
        <textarea name="Message" rows="20" cols="20" id="Message"></textarea>
        <div class="submit-btn">
        <input type="submit"/>
        </div>
    </form>
