[Resolved] Display Rules for Child Pages

This is exactly what I need, too. Case use: staff bio pages where the staff Position is a custom field with an Element to display the custom field under the title. My current workaround is to Display > All Pages with PHP to filter for the ancestor page id. Main Staff Page (ID: 44) > Individual Staff Bio Pages:

$post_id = get_the_ID();
$ancestors = get_ancestors( $post_id, 'page');
if($ancestors[0]==44) {...};

With the Child Of display rule, this could then be done in a Page Header with the {{custom_field.name}} tag without the filter.

Also, a similar function in WP Show Posts where you can create a list of all children (I had previously mentioned this too you in email on 3/19/2018). Currently I just manually enter the individual Page IDs, but that’s tedious for maintenance as pages are added/removed. Same case use as above, where the same custom field is inserted into the list with a WP Show Post Code Snippet.

[Staff (ID: 44) lists the staff name and Position, then click-thru to the individual bio page for details.]

There is the get_children() function, but I can see how that can get cumbersome with recursion. With an Elements Display > Child Of, I can see a lot of iterations to check every page and determine if a display rule applies: get_ancestors(get_the_ID()) and determine if the given Parent ID on each Element with a Child Of rule exists for the current Page ID.

WP Show Posts Pro doesn’t do child lists yet, but the workaround is to use a plugin like Add Category to Pages, then creating a list with that Page Category. This works just as well as a child page list would for me; I just have to be sure to assign the Pages to the Category.

Thanks for the replies and ideas. I ended up creating a custom post type and archive page instead to display all the items.

Hi @Tom, any updates on this ?

Thanks
