我们如何在 WordPress 页面和帖子中添加 PHP 代码?

How can we add PHP code on WordPress pages and posts?

<?PHP
    try
    {
        function visitor_country()
        {
            $client  = @$_SERVER['HTTP_CLIENT_IP'];
            $forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
            $remote  = $_SERVER['REMOTE_ADDR'];
            $result  = "Unknown";
            if(filter_var($client, FILTER_VALIDATE_IP))
            {
                $ip = $client;
            }
            elseif(filter_var($forward, FILTER_VALIDATE_IP))
            {
                $ip = $forward;
            }
            else
            {
                $ip = $remote;
            }

            $ip_data = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=" . $ip));

            if($ip_data && $ip_data->geoplugin_countryName != null)
            {
                $result = array('ip' => $ip,
                                'continentCode' => $ip_data->geoplugin_continentCode,
                                'countryCode' => $ip_data->geoplugin_countryCode,
                                'countryName' => $ip_data->geoplugin_countryName,
                                );
            }
            return $result;
        }


        $visitor_details = visitor_country(); // Output Country name [Ex: United States]
        $country = $visitor_details['countryName'];

推荐答案

WordPress 默认不会在帖子/页面内容中执行 PHP，除非它有短代码.

WordPress does not execute PHP in post/page content by default unless it has a shortcode.

执行此操作的最快和最简单的方法是使用一个插件，该插件允许您运行嵌入在帖子内容中的 PHP.

The quickest and easiest way to do this is to use a plugin that allows you to run PHP embedded in post content.

还有另外两种快速而简单"的方法可以在没有插件的情况下完成它:

There are two other "quick and easy" ways to accomplish it without a plugin:

• 将其设为短代码(将其放入 functions.php 并使其与国家/地区名称相呼应)，这非常简单 - 请参阅此处:WP Codex 的 Shortcode API

• Make it a shortcode (put it in functions.php and have it echo the country name) which is very easy - see here: Shortcode API at WP Codex

将其放入模板文件 - 根据您的默认页面模板为该页面创建自定义模板，并将 PHP 添加到模板文件中而不是帖子内容中:自定义页面模板

Put it in a template file - make a custom template for that page based on your default page template and add the PHP into the template file rather than the post content: Custom Page Templates
