Description

Implement "oik_shortcode_content" to pre-paginate the shortcode content

We should have already worked out the pagination with the following values set. [posts_per_page] => 3 [bwscid] => 1 [paged] => 1 To make the pagination logic work we need to fiddle bw_query to look like we've actually done some SQL. We also need to indicate to the front-end that the pagination is content based.

Usage

$string = oika_oik_shortcode_content( $content, $atts, $tag );

Parameters

$content

( string ) required – content to be paginated

$atts

( array ) required – shortcode attributes

$tag

( string ) required – the shortcode

Returns

string that part of the content to be processed
