修复wordpress分类分页无效

文章目录

最近在处理新站点陌泊小程序的时候，使用到了wordpress作为后台支持，在自定义主题时发现分页的时候总是返回404。数次度娘无果，最终寻求谷歌。

路途漫漫，但是功夫不负有心人，最终使用一个插件解决Category pagination fix。

知其然，还要知其所以然。原文注释提到：the 'page' looks like a post name, not the keyword "page"，也就是说wordpress会把分页路径中的page当成文章名来处理，自然就找不到了。

整个插件内容如下：

/**
 * This plugin will fix the problem where next/previous of page number buttons are broken on list
 * of posts in a category when the custom permalink string is:
 * /%category%/%postname%/ 
 * The problem is that with a url like this:
 * /categoryname/page/2
 * the 'page' looks like a post name, not the keyword "page"
 */
function remove_page_from_query_string($query_string)
{ 
    if ($query_string['name'] == 'page' && isset($query_string['page'])) {
        unset($query_string['name']);
        // 'page' in the query_string looks like '/2', so i'm spliting it out
        list($delim, $page_index) = split('/', $query_string['page']);
        $query_string['paged'] = $page_index;
    }      
    return $query_string;
}
// I will kill you if you remove this. I died two days for this line 
add_filter('request', 'remove_page_from_query_string');

// following are code adapted from Custom Post Type Category Pagination Fix by jdantzer
function fix_category_pagination($qs){
	if(isset($qs['category_name']) && isset($qs['paged'])){
		$qs['post_type'] = get_post_types($args = array(
			'public'   => true,
			'_builtin' => false
		));
		array_push($qs['post_type'],'post');
	}
	return $qs;
}
add_filter('request', 'fix_category_pagination');

另外，在用wp_query请求内容的时候，需要记得传递分页参数 paged 。
