Link category to page, enable parent class in wp_list_pages

    Hi everyone,
    I’d like to show/display posts of a category, as children of a page (or sub-page), maybe logically linked to that category.

    Here is an example:

    • Page 1
    • Sub-page a
    • Sub-page b
    • Page 2
    • Sub-page X
    • Sub-page Y
    • Page 3
    • Sub-page I
    • Sub-page II
    • Page 4
    • Sub-page i
    • Sub-page ii

    For example I need to link Sub-page II to a specific category named Category XYZ.
    Plus, while displaying a post (or a posts list) of Category XYZ, I need that wp_list_pages appends the current_page_ancestor and/or current_page_parent class to the Sub-page II list item.

    Thanks in advance,
    Alessandro Raffa

    Start by considering the use of a plugin such as Page-Links To to ‘link’ that page with your category URL.

    Or code your Page Templates to display posts from the appropriate category.

    Hi MichaelH,
    and thanks for your quick answer.

    I’ve already coded my page template, so when I visit Sub-page II I can see the_title() and the_content() of the page followed by a list of posts associated with Category XYZ. While visiting Sub-page II, wp_list_pages correctly appends the class current_page_ancestor to Page 3, and current_page_item to Sub-page II, and it’s ok. But when I visit a post of Category XYZ, wp_list_pages (as in its nature) does not append classes.

    I think I have to:

    • create page-category pairs (maybe stored in the database or in a text file)
    • modify wp_list_pages, so when WordPress displays a post of a category, it will append the right class to the list of pages

    Also I tried these plugins:

    • Page Links To
    • Page Menu Editor
    • Page Lists Plus
    • Page Link Manager
    • Super Categories
    • Top Level Categories

    They are wonderful, but they can’t help me ??

    Thanks for your help.

    Ok,
    I started writing a plugin just for this case.

    I’m adding a filter on wp_list_pages to:

    • create an array that links pages and categories
    • check if the current displayed content is a post
    • check if the current post has at least one category
    • retrieve the first cat_ID from the current post
    • extract each li element from wp_list_pages
    • for each li element of the list:
    • retrieve the page_ID
    • check if the current page_ID is linked with the cat_ID (this information is on the array)
    • if yes, replace the class attribute of the li element, adding current_page_parent in the right place
    • rebuild the wp_list_pages output with the replaced strings

    This is just a tweak/fix useful for me. Maybe it’s not a good plugin idea. But it seems perfect for my current project. Just for the information architecture I choose.

    If someone needs a plugin like this, maybe I could start write a community plugin with an option page instead of the array inside the code ??

    And submit the plugin to the repository…
