实际上，有一种非常简单的方法来完成这项特定的任务。
方法一
Follow these steps to easily create a custom RSS feed in your WordPress website:
<创建自定义页面模板。将其命名为your\\u custom\\u提要。php将第一个代码块中的代码粘贴到您的自定义提要中。php上传您的\\u自定义\\u提要。php到当前活动的WordPresstheme目录
You can now access your Custom Feed at: 您的域。com/自定义源/用户段塞/
学分转到Joost de Valk 发布优秀的article. 然而，我从原始文章中稍微修改了他的代码。

function custom_rss_date( $timestamp = null ) {
$timestamp = ($timestamp==null) ? time() : $timestamp;
echo date(DATE_RSS, $timestamp);
}
function custom_rss_text_limit($string, $length, $replacer = \'...\') {
$string = strip_tags($string);
if(strlen($string) > $length)
return (preg_match(\'/^(.*)\\W.*$/\', substr($string, 0, $length+1), $matches) ? $matches[1] : substr($string, 0, $length)) . $replacer;
return $string;
}
function custom_rss_post_id() {
global $wp_query;
$thePostID = $wp_query->post->ID;

You could place this in your current active WordPress theme functions.php file:
// Tell the hourly cronjob what operation it needs to perform.
add_action(\'update_custom_user_feeds\', \'create_custom_user_feeds\');
// Create a cronjob to update our custom feeds hourly.
function cron_custom_user_feeds(){
if(!wp_next_scheduled(\'update_custom_user_feeds\')){
wp_schedule_event(current_time(\'timestamp\'), \'hourly\', \'update_custom_user_feeds\');
}
}
add_action(\'init\', \'cron_custom_user_feeds\');
// Delete our hourly cronjob when the theme is changed.
function clear_custom_user_feeds(){
wp_clear_scheduled_hook(\'update_custom_user_feeds\');
}
add_action(\'switch_theme\', \'clear_custom_user_feeds\');
// Generate the custom user feeds
function create_custom_user_feeds(){
// "Custom Feed" is the main feed page.
$feedParent = get_page_by_title(\'Custom Feed\', \'OBJECT\', \'page\');
if(!$feedParent){
$pageData = array(
\'post_title\' => \'Custom Feed\',
\'post_name\' => \'custom-feed\',
\'post_status\' => \'publish\',
\'post_type\' => \'page\'
);
// Create custom user feed.
$parentID = wp_insert_post($pageData);
} else{
$parentID = $feedParent->ID;
}
$wpUsers = get_users();
for($i = 0; $i < count($wpUsers); $i++){
// Check if the custom user feed already exists.
$userFeed = get_page_by_title($wpUsers[$i]->user_nicename, \'OBJECT\', \'page\');
if(!$userFeed){
$pageData = array(
\'post_title\' => $wpUsers[$i]->user_nicename,
\'post_name\' => $wpUsers[$i]->user_nicename,
\'post_status\' => \'publish\',
\'post_type\' => \'page\',
\'post_parent\' => $parentID
);
// Create custom user feed.
$insertPage = wp_insert_post($pageData);
if($insertPage){
// Assign our custom feed template.
update_post_meta($insertPage, \'_wp_page_template\', \'your_custom_feed.php\');
}
}
}
// Attempt to flush caches
wp_cache_flush();
if(function_exists(\'w3tc_objectcache_flush\')){
w3tc_objectcache_flush();
}
if(function_exists(\'w3tc_pgcache_flush\')){
w3tc_pgcache_flush();
}
if(function_exists(\'w3tc_minify_flush\')){
w3tc_minify_flush();
}
if(function_exists(\'w3tc_dbcache_flush\')){
w3tc_dbcache_flush();
}
}
现在，我并不是说这个解决方案是可行的，但它是有效的。
或者，您可以使用我创建的这个类add_feed();

Directions for using this class method within your theme. (Note: This class could easily be integrated into a plugin.)
<在当前活动的WordPress主题中创建一个子目录。将其命名为：“inc”。（目录结构应如下所示：/wp-content/themes/your\\u-theme/inc/）/li>
创建一个PHP文件，并将代码块放在文件的下面（此答案中的第三个/最后一个代码块）。将其另存为自定义提要。php上传自定义提要。php进入“inc”目录可能需要停用并重新激活主题才能生效You can now access your Custom Feed at: 您的域。com/提要/自定义用户slug/
Note: 您可以将前缀“custom”（自定义）更改为您想要的任何内容。只需在类构造函数中配置设置。

Note: 我不知道它在大型网站上的表现如何。尽管如此，我设置这个类的方式允许轻松操作。您可以使用这个类来生成自定义帖子类型的提要，也可以使用自定义分类法。我的自定义Feeds类已经在WordPress 3.4.1上进行了测试，并且工作正常。
如果您想以我当前设置的方式使用它，那么只需在类构造函数中配置提要设置。
