wordpress使用郵件追蹤404頁(yè)面

    作為一個(gè)有意識(shí)的web開發(fā)者/網(wǎng)站的所有者，你可能想跟蹤您的網(wǎng)站或博客的404頁(yè)。當(dāng)然你可以分析你站點(diǎn)的訪問日志文件，但我們今天要講的是一個(gè)更好的追蹤方式，那就是通過發(fā)送郵件報(bào)告。這樣我么就能更加及時(shí)的獲取404頁(yè)面的情況。
    如果你的主題沒有404.php文件，你必須創(chuàng)建他，然后將一下代碼添加到你的404頁(yè)面中：
    注意：使用該方法前提是你的wordpress支持郵件發(fā)送。
    // 設(shè)置頁(yè)面狀態(tài)
    header(http/1.1 404 not found);
    header(status: 404 not found);
    // 站點(diǎn)信息
    $blog = get_bloginfo('name');
    $site = get_bloginfo('url') . '/';
    $email = get_bloginfo('admin_email');
    // 主題信息
    if (!empty($_cookie[nkthemeswitch . cookiehash])) {
    $theme = clean($_cookie[nkthemeswitch . cookiehash]);
    } else {
    $theme_data = wp_get_theme();
    $theme = clean($theme_data->name);
    }
    // 獲取來源地址
    if (isset($_server['http_referer'])) {
    $referer = clean($_server['http_referer']);
    } else {
    $referer = undefined;
    }
    // 來源 uri
    if (isset($_server['request_uri']) && isset($_server[http_host])) {
    $request = clean('http://' . $_server[http_host] . $_server[request_uri]);
    } else {
    $request = undefined;
    }
    // 查詢字符串
    if (isset($_server['query_string'])) {
    $string = clean($_server['query_string']);
    } else {
    $string = undefined;
    }
    // ip 地址
    if (isset($_server['remote_addr'])) {
    $address = clean($_server['remote_addr']);
    } else {
    $address = undefined;
    }
    // 用戶客戶端信息 agent
    if (isset($_server['http_user_agent'])) {
    $agent = clean($_server['http_user_agent']);
    } else {
    $agent = undefined;
    }
    // 用戶連接協(xié)議
    if (isset($_server['remote_ident'])) {
    $remote = clean($_server['remote_ident']);
    } else {
    $remote = undefined;
    }
    // 記錄時(shí)間
    $time = clean(date(y-m-d h:i:s, time()));
    // 組合信息
    function clean($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;
    }
