Category pagination broken with certain permalink structures

[rmccue]

If one uses a permalink structure with %category% followed by %postname%, accessing pagination can cause a 404, as WordPress attempts to look for a post called "page".

As per ​http://barefootdevelopment.blogspot.com/2007/11/fix-for-wordpress-paging-problem.html

Presumably can occur with other permalink structures too.

I proposed a possible solution here in #9379

Ran into this issue today - would love to see a fix.

I'm not sure if it is as simple as putting some extra logic in parse_request()? Using Doug Smith's code as inspiration, I added the following right before $this->query_vars = apply_filters('request', $this->query_vars); :

if ($this->query_vars['name'] === 'page' && isset($this->query_vars['page'])) {
	unset($this->query_vars['name']);
	$this->query_vars['paged'] = str_replace('/', '', $this->query_vars['page']);
}

Thoughts?

​http://wordpress-core/uncategorized/test-post-goes-here-this-is-some-more/2/ totally works for me when using <!--nextpage--> and navigating to page 2

Pretty sure this was fixed when some of the permalink stuff was redone.

This ticket is about category pagination, not single post pagination.

As noted in #21209, the issue still can be reproduced with bare category slugs:

1. Set permalink structure to /%category%/%postname%/.
2. http://mysite/mycat/page/2 gives a 404 error.

Debug Bar info:

Request: mycat/page/2
Query String: page=%2F2&name=page&category_name=mycat
Matched Rewrite Rule: (.+?)/([^/]+)(/[0-9]+)?/?$
Matched Rewrite Query: category_name=mycat&name=page&page=%2F2

This is already fixed. Unless there is some new issue that is not clear here, then this should probably be closed. @SergeyBiryukov's reproduction steps produce the second page now, not a 404. It's not my place to close this, but I'm pretty sure it can be closed as resolved.

When there's a post with the slug page, http://mysite/mycat/page/2 shows that post. If there's none, I get a 404.

Hi there,

Paginate_links function inside page template works fine. I can display a category with pagination using a page template pagetemplate-categoryname.php but not a category-categoryname.php, or even the root category.php template in a theme.

For slug page mentioned above the paginate_links would look like this:

<?php
					echo paginate_links( array(
						'format' => 'page/%#%',
						'current' => max( 1, get_query_var('paged') ),
						'total' => $wp_query->max_num_pages,
						'prev_next'    => True,
						'prev_text'    => __("<i class=\"material-icons\">chevron_left</i>"),
						'next_text'    => __("<i class=\"material-icons\">chevron_right</i>"),
						'type' => 'list',
					));
				?>

There is a "category pagination fix" plugin being offered for category pagination when this should be part of core features of a content management system:

Thank you for your time.
