Typecho 显示评论者国家和浏览器

Typecho 由于插件稀少,一直没有找到显示评论者国家和浏览器的插件,所以只好自力更生了。

代码修改自WordPress插件Show UserAgent,下载页面:https://wordpress.org/plugins/show-useragent/

前提是你的主题使用了自定义评论代码而不是Typecho默认的评论显示代码,一般符合要求的主题的comments.php或者functions.php中会有如下代码:

<?php function threadedComments($comments, $options) {
    //blablabla
?>

下载Show UserAgent插件解压,把里面的flags文件夹改名成country,browsers文件夹改名成browser,ip2c文件夹改名成lib,上传到服务器上你的主题文件夹。(其实不改也可以,但是我是按照个人习惯这么改的,你也可以修改下面代码的路径)

在主题的functions.php中插入这么长一串代码:

<?php /* 地理位置判断 */ ?>
<?php function CID_get_country($ip) {
    require_once(dirname(__FILE__).'/lib/ip2c.php');
    if (isset($GLOBALS['ip2c'])) {
        global $ip2c;
    } else {
        $ip2c = new ip2country(dirname(__FILE__).'/lib/ip-to-country.bin');
        $GLOBALS['ip2c'] = $ip2c;
    }
    return $ip2c->get_country($ip);
}

function CID_get_flag($ip, $show_image = true, $show_text = false, $before = '', $after = '') {
    if($ip == '127.0.0.1'){
        $code = 'wordpress';
        $name = 'Localhost';
    }else{

    $country = CID_get_country($ip);
    if (!$country) return "";

    $code = strtolower($country['id2']);
    $name = $country['name'];
    }
    global $CID_options;

    $output = '';

    if ($show_image)
        $output = ' <img src="http://cdn.lantian.lt/usr/themes/hybridside/lib/country/' . $code . '.png" title="' . $name . '" alt="' . $name . '" class="country-flag" />';
    if ($show_text)
        $output .= ' ' . $name;

    return $before . $output . $after;
}
?>

把里面的http://cdn.lantian.lt/usr/themes/hybridside这个网址全部改成你的主题文件夹的网址。

在主题的自定义评论代码里你想显示评论者国家的地方插入:

<?php echo CID_get_flag($comments->ip);?>

在你想显示系统和浏览器的地方插入:

<?php echo CID_browser_string($comments->agent);?>

修改完成,测试效果。
