wordpress链接文章不显示category栏目显示

如果你的wordpress网站，想在访问文章链接时不显示category，直接显示文章的别名或ID，而在访问栏目时显示category，那么你可以将下面的代码添加到functions.php中即可。

add_filter('request', function($query_vars) {
	if(!isset($_GET['page_id']) && !isset($_GET['pagename']) && !empty($query_vars['pagename'])){
		$pagename	= $query_vars['pagename'];
		$categories	= get_categories(['hide_empty'=>false]);
		$categories	= wp_list_pluck($categories, 'slug');
 
		if(in_array($pagename, $categories)){
			$query_vars['category_name']	= $query_vars['pagename'];
			unset($query_vars['pagename']);
		}
	}
 
	return $query_vars;
});
 
add_filter('pre_term_link', function($term_link, $term){
	if($term->taxonomy == 'category'){
		return '%category%';
	}
 
	return $term_link;
}, 10, 2);
