下面是一个相当完整的示例，说明了一种方法。
让我们注册一个将与feed一起使用的职位类型。
/**
* Register Job post type
* https://developer.wordpress.org/reference/functions/register_post_type/
*/
function wpse_register_job_post() {
$book_args = [
\'label\' => __( \'Jobs\', \'textdomain\' ),
\'public\' => true,
\'publicly_queryable\' => true,
\'show_ui\' => true,
\'show_in_menu\' => true,
\'query_var\' => true,
\'rewrite\' => [ \'slug\' => \'jobs\' ],
\'capability_type\' => \'post\',
\'has_archive\' => true,
\'hierarchical\' => false,
\'menu_position\' => null,
\'supports\' => [ \'title\', \'editor\', \'author\', \'thumbnail\', \'excerpt\', \'comments\', \'custom-fields\' ],
];
register_post_type( \'jobby_job\', $book_args );
}
add_action( \'init\', \'wpse_register_job_post\' );
现在来看好东西。让我们创建自定义提要和渲染器。可以通过访问
http://example.com/?feed=indeedRegister Feed
/**
* Create a custom feed.
* https://developer.wordpress.org/reference/functions/add_feed/
*/
function wpse_add_indeed_job_feed() {
add_feed( \'indeed\', \'wpse_render_indeed_job_feed\' );
}
add_action( \'init\', \'wpse_add_indeed_job_feed\' );
Render Feed
/**
* Render our custom feed.
*/
function wpse_render_indeed_job_feed() {
header( \'Content-Type: \' . feed_content_type( \'rss2\' ) . \'; charset=\' . get_option( \'blog_charset\' ), true );
echo \'<?xml version="1.0" encoding="\' . get_option( \'blog_charset\' ) . \'"?\' . \'>\';
?>
<source>
<publisher><?php wp_title_rss(); ?></publisher>
<publisherurl><?php echo get_site_url(); ?></publisherurl>
<lastBuildDate><?php echo date( \'D, j M Y G:i:s\' ) . \' GMT\'; ?></lastBuildDate>
<?php
// Get the job posts. Customize arguments as needed.
$job_query = new WP_Query( [
\'post_type\' => \'jobby_job\',
\'posts_per_page\' => 42,
] );
if ( $job_query->have_posts() ) {
while ( $job_query->have_posts() ) {
$job_query->the_post();
// Note: You\'ll need to get the various post meta fields and add them below.
// Use get_post_meta() or for ACF, get_field() can be used.
// Meta is hard coded in this example.
?>

<?php } ?>
<?php } ?>
</source>
<?php
wp_reset_postdata();
}
作为参考，WP的默认RSS提要模板位于
wp-includes/feed-rss2.php.
记住在定制提要时要清除缓存，因为浏览器往往会缓存输出。
