EMLOG修改系统默认的emMsg为自适应风格的方法
EMLOG原生的系统提示emMsg比较简单，对于喜欢动手的大神们来说显得比较素，现在就来为大家分享一个EMLOG修改系统默认的emMsg为自适应风格的方法，让系统提示看起来更加高大上。
一、操作步骤
1、打开/include/lib/function.base.php文件，大约在第858至920行找到如下代码
/**
* 显示系统信息
*
* @param string $msg 信息
* @param string $url 返回地址
* @param boolean $isAutoGo 是否自动返回 true false
*/
function emMsg($msg, $url = 'javascript:history.back(-1);', $isAutoGo = true) {
if ($msg == '404') {
header("HTTP/1.1 404 Not Found");
$msg = '抱歉，你所请求的页面不存在！';
}
echo <<<EOT
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="zh-CN">
<head>
EOT;
if ($isAutoGo) {
echo "<meta http-equiv=\"refresh\" content=\"2;url=$url\" />";
}
echo <<<EOT
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>提示信息</title>
<style type="text/css">
<!--
body {
background-color:#F7F7F7;
font-family: Arial;
font-size: 12px;
line-height:150%;
}
.main {
background-color:#FFFFFF;
font-size: 12px;
color: #666666;
width:650px;
margin:60px auto 0px;
border-radius: 10px;
padding:30px 10px;
list-style:none;
border:#DFDFDF 1px solid;
}
.main p {
line-height: 18px;
margin: 5px 20px;
}
-->
</style>
</head>
<body>
<div class="main">
<p>$msg</p>
EOT;
if ($url != 'none') {
echo '<p><a href="' . $url . '">«点击返回</a></p>';
}
echo <<<EOT
</div>
</body>
</html>
EOT;
exit;
}
2、将上面的代码替换为如下代码，保存上传覆盖即可
/**
* 显示系统信息
*
* @param string $msg 信息
* @param string $url 返回地址
* @param boolean $isAutoGo 是否自动返回 true false
*/
function emMsg($msg, $url = 'javascript:history.back(-1);', $isAutoGo = false) {
if ($msg == '404') {
header("HTTP/1.1 404 Not Found");
$msg = '抱歉，你所请求的页面不存在！';
}
echo <<<EOT

EOT;
if ($isAutoGo) {
echo "<meta http-equiv=\"refresh\" content=\"2;url=$url\" />";
}
echo <<<EOT
