您需要使用add_rewrite_rule 注册新URL，然后创建新页面（&P）；要处理链接位置的模板。

例如：

add_action(\'init\', function() {
    $page_id = 2;
    $page_data = get_post($page_id);

    if(!is_object($page_data)) {
        return;
    }

    add_rewrite_rule(
        $page_data->post_name . \'/go/([^/]+)/?$\',
        \'index.php?pagename=\' . $page_data->post_name . \'&affiliate=$matches[1]\',
        \'top\'
    );
});

您还需要使用add\\u filter来设置变量：

add_filter(\'query_vars\', function($vars) {
    $vars[] = "affiliate";
    return $vars;
});

$affiliate = get_query_var(\'affiliate\', false);
// Do whatever lookup you need here to get the actual link to redirect to
wp_redirect($url);
exit;

此解决方案无需创建新页面或更改任何内容。

我们将：
1。设置新的重写规则并添加新的查询变量
2。在“pre\\u get\\u posts”钩子中捕获该情况，获取我们需要的帖子并执行重定向

请注意，如果您有多篇具有相同keyword_meta 值，这可能无法按计划工作。我尚未对此进行检查，将选择第一个匹配的帖子。

代码应进入functions.php 或类似：

add_action( \'init\',
    function () {
        add_rewrite_rule(
            \'^(go)\\/([^\\/]+)$\',
            \'index.php?redirection=$matches[2]\',
            \'top\'
        );

        add_filter( \'query_vars\',
            function ( $vars ) {
                $vars[] = "redirection";

                return $vars;
            } 
        );
    }
);

add_action( \'pre_get_posts\',
    function ( $query ) {
        if ( $redirection = get_query_var( \'redirection\' ) ) {

            // Change this:
            $keyword_meta         = \'keyword_meta_field_name\';
            $redirection_url_meta = \'redirection_url_meta_field_name\';
            $post_type            = \'post\';

            $args = [
                \'meta_key\'       => $keyword_meta,
                \'meta_value\'     => $redirection,
                \'posts_per_page\' => 1,
                \'post_type\'      => $post_type,
            ];

            $post_query = new WP_Query( $args );
            $posts      = $post_query->get_posts();

            // If no posts found, redirect back to referer
            if ( count( $posts ) < 1 ) {
                wp_safe_redirect( wp_get_referer() );
            }

            $redirection_url = get_post_meta( $posts[0]->ID, $redirection_url_meta, true );

            // If no redirection URL found, redirect back to referer
            if ( ! $redirection_url ) {
                wp_safe_redirect( wp_get_referer() );
            }

            // Finally, do the redirection
            if ( headers_sent() ) {
                echo( "<script>location.href=\'$redirection_url\'</script>" );
            } else {
                header( "Location: $redirection_url" );
            }
            exit;
        }

        return $query;
    }
);
