_bw_get_posts() – Wrapper to WP_query::query()

Description

Wrapper to WP_query::query()

Sometimes we need to know more about the results of the query than just the posts We need to find the total number of posts in order to work out how many pages there are. This information is available from WP_Query when displaying paged content. This function implements most of get_posts() but it returns the WP_Query object that was used.

Usage

$array = _bw_get_posts( $args );

Parameters

$args

( array ) optional – parameters to get_posts or WP_query::query()

Returns

array $posts – the posts
