The more difficult point in this video is that phpmailer sends emails:

PHPMailer is an encapsulated PHP mail sending class that supports sending emails with HTML content and image attachments. The prerequisite is to set up the mail server to realize the mail sending function.
HTML

First we place an inbox input box and a send email button:

收件人：<input type="text" class="input_text" id="email" name="email" value="@"/> 
<input type="button" class="btn" id="send" value="发送"/>

jQuery

$(function() { 
    $("#send").click(function() { 
        var email = $("#email").val(); 
        $("#send").addClass("loading").val("loading...").attr("disabled", "disabled"); 
        $.post("ajax.php", { 
            "email": email 
        }, 
        function(data) { 
            if (data == 1) { 
                $("#result").html("发送成功，请注意查收您的邮件！"); 
            } else { 
                $("#result").html(data); 
            } 
            $("#send").removeAttr("disabled").removeClass("loading").val("发送"); 
        }); 
    }); 
});

Ajax.php

require_once('class.phpmailer.php'); 
$address = $_POST['email']; //收件人email 
$mail = new PHPMailer(); //实例化 
$mail->IsSMTP(); // 启用SMTP 
$mail->Host = "smtp.163.com"; //SMTP服务器 以163邮箱为例子 
$mail->Port = 25;  //邮件发送端口 
$mail->SMTPAuth = true;  //启用SMTP认证 
 
$mail->CharSet = "UTF-8"; //字符集 
$mail->Encoding = "base64"; //编码方式 
$email_system = "qiumusua@163.com"; 
$mail->Username = $email_system;  //你的邮箱 
$mail->Password = "";  //你的密码 
$mail->Subject = "你好"; //邮件标题 
 
$mail->From = $email_system;  //发件人地址（也就是你的邮箱） 
$mail->FromName = "素材火";  //发件人姓名 
$mail->AddAddress($address, "亲"); //添加收件人（地址，昵称） 
 
$mail->AddAttachment('send.xls', '我的附件.xls'); // 添加附件,并指定名称 
$mail->IsHTML(true); //支持html格式内容 
$mail->AddEmbeddedImage("logo.jpg", "my-attach", "logo.jpg"); //设置邮件中的图片 
$mail->Body = &#39;你好, <b>朋友</b>! <br/>这是一封来自<a href="http://www.erdangjiade.com" target="_blank">erdangjiade.com</a>的邮件！<br/>
<img alt="erdangjiade" src="cid:my-attach">&#39;; //邮件主体内容 
//发送 
if (!$mail->Send()) { 
    echo "发送失败: " . $mail->ErrorInfo; 
} else { 
    echo "1"; 
}
