PHP发送邮箱快速发送邮箱发送邮箱

保持输入较少的内容但尽量获取更多的信息的原则

获取当前的URL和来源的URL的方法

<!DOCTYPE html>
<html lang="zh-cn">
<head>
<meta charset="UTF-8">
<title>获取当前的URL和来源的URL的方法</title>
</head>
<body>
<script>
var fromurl = document.referrer;
var nowurl = document.URL;
document.writeln("来源的URL："+fromurl+"<br>");
document.writeln("当前的URL："+nowurl);
</script>	
</body>
</html>

效果图：

开始发送邮箱

<meta charset="UTF-8">
<?php
	if(!$_POST){
		exit;
	}
	require_once "email.class.php";
	$smtpserver = "smtp.163.com";
	$smtpserverport =25;
	$smtpusermail = "onestopweb@163.com";//发送人
	$smtpemailto = "onestopweb@qq.com";//接收人
	$smtpuser = "onestopweb";
	$smtppass = "123456";
	$mailtype = "HTML";
	
	$genre = strFilter($_POST['genre']);//类别
	$username = strFilter($_POST['username']);//姓名
	$tel = strFilter($_POST['tel']);//电话
	$datetime = strFilter($_POST['datetime']);//日期时间
	$fromurl = strFilter($_POST['fromurl']);//来源URL
	$nowurl = strFilter($_POST['nowurl']);//当前的URL
	
	function strFilter($str){
		//过滤HTML的标记和分号
		$str = str_replace('\'', '&#39;', $str);
		$str = str_replace('\'', '&#39;', $str);
		$str = str_replace('\\', '', $str);   		
		$str = str_replace('"', '&#34;', $str);
		$str = str_replace('<', '&#60;', $str);
		$str = str_replace('>', '&#62;', $str);
		return trim($str);
	}
		
	$mailtitle = $username."发送邮箱";
	$mailcontent = "<style>.guahao{ width:100%; border-top:1px solid #333; border-left:1px solid #333;}.guahao td{ border-bottom:1px solid #333; border-right:1px solid #333; padding:0 8px; width:50%;}.guahao tr:nth-child(even){ background:#ffc;}</style>";
	$mailcontent .= '<table cellpadding="0" cellspacing="0" class="guahao">';
	$mailcontent .= '<tr><td colspan="2" align="center" style="font-weight:bold;">'.$username.'发送邮箱</td></tr>';
	$mailcontent .= '<tr><td align="right">类　别：</td><td>'.$genre.'</td></tr>';
	$mailcontent .= '<tr><td align="right">姓　名：</td><td>'.$username.'</td></tr>';
	$mailcontent .= '<tr><td align="right">电　话：</td><td>'.$tel.'</td></tr>';
	$mailcontent .= '<tr><td align="right">日　期：</td><td>'.$datetime.'</td></tr>';
	$mailcontent .= '<tr><td align="right">来源URL</td><td>'.$fromurl.'</td></tr>';
	$mailcontent .= '<tr><td align="right">当前URL</td><td>'.$nowurl.'</td></tr>';
	$mailcontent .= '</table>';
	
	$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证.
	$smtp->debug = false;//是否显示发送的调试信息
	$state = $smtp->sendmail($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, $mailtype);

	echo "<div style='width:300px; margin:36px auto;'>";  
    if($state==""){  
        echo "对不起，信息提交失败！请检查信息是否填写完整。";  
        echo "<script type='text/javascript'>alert('对不起，信息提交失败，请重新填写信息。');location.href='".$nowurl."';</script>"; 
        exit();  
    }  
    echo "恭喜！信息提交成功。";  
    echo "<script type='text/javascript'>alert('恭喜！信息提交成功。');location.href='".$nowurl."';</script>";   
    echo "</div>";  
?>
