categories - Custom permalink structure leads to be 404 on pagination

admin管理员组

I have a permalink issue. For your information, there are a few different categories within a website and there are many posts in a single category.

My permalink setting is:

Custom Stucture: /%category%/%postname%/

Category Base: .

After this setting saved, my url will be

www.mydomain/category-slug-name/

instead of

www.mydomain/category/category-slug-name/

I have set the Blog pages show at most: 8 posts under the Setting > Reading. The pagination will appear when there are more than 8 posts in a category page.

I clicked on "page 2", and noticed that www.mydomain/category-slug-name/page/2/ brought me to 404 error page.

Originally, the url of any category "page2" is www.mydomain/category/category-slug-name/page/2/, it works fine if there is "category" within the url as original url. Or else, it would be 404 error page.

My main concern is, I don't want the category appear in the url. But i want the slug name of category appear in url when i viewing the selected post. And "/page/2/" and the rest will work fine.

Hopefully that this issue is not going to be resolved with recommended plugins. Because, I don't want the website to be too heavy.

Any suggestions?

That is totally normal behaviour. If you want to remove category base you will need to write some custom rewrite rules, not simple rules I must say. From my point of view, removing category base requires a extra job in each request that is worthless because it doesn't provide any advantage for SEO or for better site navigation. Some popular plugins, like WordPres SEO by Yoast, had this option in the past and removed it some time ago. But this is just an opinion.

Configure category base to . (dot), put this code in the functions.php of your theme, or better in a plugin, and flush the rewrite rules (code from this post in Daily Web Kit):

add_filter( 'category_rewrite_rules', 'vipx_filter_category_rewrite_rules' );
function vipx_filter_category_rewrite_rules( $rules ) {
    $categories = get_categories( array( 'hide_empty' => false ) );

    if ( is_array( $categories ) && ! empty( $categories ) ) {
        $slugs = array();
        foreach ( $categories as $category ) {
            if ( is_object( $category ) && ! is_wp_error( $category ) ) {
                if ( 0 == $category->category_parent ) {
                    $slugs[] = $category->slug;
                } else {
                    $slugs[] = trim( get_category_parents( $category->term_id, false, '/', true ), '/' );
                }
            }
        }

        if ( ! empty( $slugs ) ) {
            $rules = array();

            foreach ( $slugs as $slug ) {
                $rules[ '(' . $slug . ')/feed/(feed|rdf|rss|rss2|atom)?/?$' ] = 'index.php?category_name=$matches[1]&feed=$matches[2]';
                $rules[ '(' . $slug . ')/(feed|rdf|rss|rss2|atom)/?$' ] = 'index.php?category_name=$matches[1]&feed=$matches[2]';
                $rules[ '(' . $slug . ')(/page/(\d)+/?)?$' ] = 'index.php?category_name=$matches[1]&paged=$matches[3]';
            }
        }
    }
    return $rules;
}

This Worked for me, Add this function in your functions.php page in wordpress and this function will change your like:

Previous: http://www.example/advice/category/category_name/page/3/

To: http://www.example/advice/category_name/page/3/

function remove_category_slug_url($query_string){ 
    if ($query_string['name'] == 'page' && isset($query_string['page'])) {
        unset($query_string['name']);
        list($delim, $page_index) = explode('/', $query_string['page']);
        $query_string['paged'] = $page_index;
    }      
    return $query_string;
}
add_filter('request', 'remove_category_slug_url');

function 
 remove_category_slug_url($query_string){ 
if ($query_string['name'] == 'page' && isset($query_string['page'])) {
    unset($query_string['name']);
    list($delim, $page_index) = split('/', $query_string['page']);
    $query_string['paged'] = $page_index;
}      
return $query_string;
 }
 add_filter('request', 'remove_category_slug_url');

This Worked for me, Add this function code in your functions.php in wordpress

note: go to settings->permalinks and click on "save". This will make that WordPress rebuild the rewrite rules taking in account the new ones

For anyone else having this problem, with the redirects on paginated pages, the following worked for me:

In your permalinks, change: /%category%/%postname%/

to

/%category%/%postname%

Notice the removal of the ending forward slash "/".

This worked for me.

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;
} 
add_filter('request', 'remove_page_from_query_string');
