Show subpages when parent page is selected

I’ve solved this issue modifiying source from function-templates.php. The functions are wp_list_pages and other (I don’t remember that now).

I will post the complete solution when I found the files (I’m not online all the time).

Regards.

Here is the code to solve the issue:

File: template-functions-post.php
Function: wp_list_pages(args = ”)
Line: 358 (aprox.)

Add next code (into the “foreach” code block):


$page_tree[$page->ID]['parent'] = $page->post_parent;

———————————–

Into the same file:
Function: _page_level_out(…)
Line: 418 (aprox.)

Add next code (into the “foreach” code block):


$current_page = $page_tree[$GLOBALS['id']]['parent'];

if(!($parent == 0 || ($GLOBALS['id'] == $cur_page['parent']) || ($current_parent == $cur_page['parent'])))
continue;

———————

I hope you’ll find it useful. Regards.

This is a feature I have wanted for a while, but hacks introduce a problem with upgrading. Does anyone know of a plugin that introduces these features?

You wouldn’t have to worry about upgrades breaking this if you defined your own functions in a seperate php file (like a plugin would). Simply copy all the function definition into your own file (myCode.php) and rename the function something like my_list_pages() and make the changes you want. Then include myCode.php once in your header or something like that.

I’ve done this for precisely this sub-page listing functionality and it works well. If you go to my “about” page all of the “recommendeds” links on the right sidebar are actually just subpages… and that little menu is dynamically generated.
