[37920] introduced resource hints that allow browsers to prefetch specific pages or render them in the background. With this change, the `as`, `crossorigin`, `pr`, and `type` attributes can be passed in addition to the URLs/hosts. Props peterwilsoncc, swissspidy. Fixes #38121. Built from https://develop.svn.wordpress.org/trunk@38826 git-svn-id: http://core.svn.wordpress.org/trunk@38769 1a063a9b-81f0-0310-95a4-ce76da25c4cd

/**
|
|
* Retrieve paginated link for archive post pages.
|
|
*
|
|
* Technically, the function can be used to create paginated link list for any
|
|
* area. The 'base' argument is used to reference the url, which will be used to
|
|
* create the paginated links. The 'format' argument is then used for replacing
|
|
* 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
|
|
* instead of a short list of the pages near the current page. By default, the
|
|
* 'show_all' is set to false and controlled by the 'end_size' and 'mid_size'
|
|
* arguments. The 'end_size' argument is how many numbers on either the start
|
|
* and the end list edges, by default is 1. The 'mid_size' argument is how many
|
|
* numbers to either side of current page, but not including current page.
|
|
*
|
|
* It is possible to add query vars to the link by using the 'add_args' argument
|
|
* and see add_query_arg() for more information.
|
|
*
|
|
* The 'before_page_number' and 'after_page_number' arguments allow users to
|
|
* augment the links themselves. Typically this might be to add context to the
|
|
* numbered links so that screen reader users understand what the links are for.
|
|
* The text strings are added before and after the page number - within the
|
|
* anchor tag.
