The previously available set of filters in the `feed_links()` function to enable or disable display of various feed links was quite limited: * `feed_links_show_posts_feed` to control the main feed * `feed_links_show_comments_feed` to control both the global comments feed and the comment feed for singular posts. In order to disable the other feeds (post type archive, category, tag, custom taxonomy, author archive, search results), one would have to unhook `feed_links_extra()` from `wp_head`, but that would completely remove all of those feeds, as well as the single post comments feed. To allow for more flexibility, this commit introduces a full set of filters in the `feed_links_extra()` function to control each one of the feeds independently, including a way to enable/disable the single post comments feed when the global comments feed is disabled/enabled: * `feed_links_extra_show_post_comments_feed` * `feed_links_extra_show_post_type_archive_feed` * `feed_links_extra_show_category_feed` * `feed_links_extra_show_tag_feed` * `feed_links_extra_show_tax_feed` * `feed_links_extra_show_author_feed` * `feed_links_extra_show_search_feed` All of them default to `true`, except for `feed_links_extra_show_post_comments_feed` which defaults to the result of `feed_links_show_comments_feed` to ensure backward compatibility. Follow-up to [33838], [33839], [53125]. Props lopo, mukesh27, audrasjb, SergeyBiryukov. Fixes #55904.

* the page number. It is however, most likely and by default, to be used on the

|
* archive post pages.
|

*
|
|
* The 'type' argument controls format of the returned value. The default is
|
|
* 'plain', which is just a string with the links separated by a newline
|
|
* character. The other possible values are either 'array' or 'list'. The
|
|
* 'array' value will return an array of the paginated link list to offer full
|
|
* control of display. The 'list' value will place all of the paginated links in
|
|
* an unordered HTML list.
|
|
*
|
|
* The 'total' argument is the total amount of pages and is an integer. The
|
|
* 'current' argument is the current page number and is also an integer.
|

*
|
|
* An example of the 'base' argument is "http://example.com/all_posts.php%_%"
|
|
* and the '%_%' is required. The '%_%' will be replaced by the contents of in
|
|
* the 'format' argument. An example for the 'format' argument is "?page=%#%"
|
|
* and the '%#%' is also required. The '%#%' will be replaced with the page
|
|
* number.
|
|
*
|
|
* You can include the previous and next links in the list by setting the
|
|
* 'prev_next' argument to true, which it is by default. You can set the
|
|
* previous text, by using the 'prev_text' argument. You can set the next text
|
|
* by setting the 'next_text' argument.
|
|
*
|
|
* If the 'show_all' argument is set to true, then it will show all of the pages
|
