wordpress报错，出现404后管理员如何收到报错信息，下面web建站小编给大家详细介绍一下具体代码！

在当前主题的functions.php文件中新增以下代码：

// 网站信息
$blog  = get_bloginfo('name');
$site  = get_bloginfo('url') . '/';
$email = get_bloginfo('admin_email');

// 主题信息
if (!empty($_COOKIE[nkthemeswitch . COOKIEHASH])) {
  $theme = clean($_COOKIE[nkthemeswitch . COOKIEHASH]);
} else {
  $theme_data = wp_get_theme();
  $theme = clean($theme_data->Name);
}

// 来源网址
if (isset($_SERVER['HTTP_REFERER'])) {
  $referer = clean($_SERVER['HTTP_REFERER']);
} else {
  $referer = undefined;
}

// 请求 URI
if (isset($_SERVER['REQUEST_URI']) && isset($_SERVER[HTTP_HOST])) {
  $request = clean('http://' . $_SERVER[HTTP_HOST] . $_SERVER[REQUEST_URI]);
} else {
  $request = undefined;
}

// 请求字符串
if (isset($_SERVER['QUERY_STRING'])) {
  $string = clean($_SERVER['QUERY_STRING']);
} else {
  $string = undefined;
}

// 用户的IP 地址
if (isset($_SERVER['REMOTE_ADDR'])) {
  $address = clean($_SERVER['REMOTE_ADDR']);
} else {
  $address = undefined;
}

// 设备类型
if (isset($_SERVER['HTTP_USER_AGENT'])) {
  $agent = clean($_SERVER['HTTP_USER_AGENT']);
} else {
  $agent = undefined;
}

// 用户识别码
if (isset($_SERVER['REMOTE_IDENT'])) {
  $remote = clean($_SERVER['REMOTE_IDENT']);
} else {
  $remote = undefined;
}

// 记录时间
$time = clean(date(F jS Y, h:ia, time()));

// 净化数据
function clean($string) {
  $string = rtrim($string); 
  $string = ltrim($string); 
  $string = htmlentities($string, ENT_QUOTES); 
  $string = str_replace(n, , $string);

  if (get_magic_quotes_gpc()) {
    $string = stripslashes($string);
  } 
  return $string;
}

$message = 
  TIME:             . $time    . n . 
  *404:             . $request . n . 
  SITE:             . $site    . n . 
  THEME:            . $theme   . n . 
  REFERRER:         . $referer . n . 
  QUERY STRING:     . $string  . n . 
  REMOTE ADDRESS:   . $address . n . 
  REMOTE IDENTITY:  . $remote  . n . 
  USER AGENT:       . $agent   . nnn;

// 最后通过邮件发送404页面通知信息
mail($email, 404 警告:  . $blog .  [ . $theme . ], $message, From: $email);
