What?
Fixes #29484
Why?
The previous patch, #37672, does not work 100% of the time. See details.
How?
The
wp_link_pages
uses the$multipage
global variable to determine whether to output pagination, so checking the same variable in this context should ensure that the pagination is output whenever there is anything to output and omitted when it would be empty.I was tempted to check
isset( $GLOBALS['multipage'] )
, but seeing thatwp_link_pages
does not include such a check, I left it out.Testing Instructions
<!--nextpage-->
tagcontent_pagination
filter to add pagination to a post that does not contain the<!--nextpage-->
