bw_get_posts() – Wrapper to get_posts()

Description

Wrapper to get_posts()

When no parameters are passed processing should depend upon the context e.g for a 'page' it should list the child pages

• for a 'post' it should show related posts in the same category as the current post

Nos	$atts[‘post_type’]	$post->post_type	Default processing
1	–	page	list child pages – first level only
2	–	post	list related posts – same categories
3	–	custom	none
4	page	page	as 1.
5	page	post	?
6	page	custom	?
7	post	page	?
8	post	post	as 2.
9	post	custom	?
10-12	custom	any	?

As you can see from the table above the default behaviour for listing posts on pages and vice-versa is not (yet) defined

Usage

$array = bw_get_posts( $atts );

Parameters

$atts

( array ) optional – shortcode parameters

Returns

array posts
