Add extra formatting parameters to wp_list_categories

[Otto42]

The wp_list_categories() function should have the following parameters added to it:
before, after, between, show_description. These would behave much the same as they do in the wp_list_bookmarks() function.

Request for this sort of functionality was made here: ​http://wordpress.org/support/topic/124374

I think it's a good idea as it further standardizes the wp_list_* functions.

Implementing this would require changes to the wp_list_categories() function, as well as changes to the Walker_Category class to actually perform the output.

I'm gonna write a patch tomorrow for this.

[thee17]

adds $before $after $link_before and $link_after

[thee17]

If I could just figure out how to work around the li and ul problem like bookmarks does it then $style could be sent to pasture.

Line 289

$output = '';
	if ( $title_li && 'list' == $style )
			$output = '<li class="categories">' . $r['title_li'] . '<ul>';

Line 314

	if ( $title_li && 'list' == $style )
		$output .= '</ul></li>';

someone should consolidate the various wp_list_* tickets into one per item type, and write a big patch.

patch is broken

[wojtek.szkutnik]

Most of other wp_list_* tickets have been already taken care of

I've looked that patch that add that content before and after but I can see that in the meanwhile that function have the style parameter that able the user to choose if he wants a html list or not.

So I think that we can consider obsolete.

[thee17]

Nowadays people use the menu system for this. I agree that it is obsolete, and not worth changing. I suggest closing as won't fix.

@thee17, could you define what you mean by "the menu system?" I'm still using this function myself, and it'd be nice if the args matched wp_list_pages, so that I don't have to create a custom walker to match the functionality.
