bw_blog() – Implement [bw_blog] shortcode to select the blog to be used in subsequent shortcodes

Description

Implement [bw_blog] shortcode to select the blog to be used in subsequent shortcodes

We might eexpect that if the blog was invalid then switch_to_blog() would fail. But it doesn't, so we need to check.

Usage

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

Parameters

$atts

( array ) optional – expected to either contain "blog" or uses the index 0 values

$content

( string ) optional – not expected

$tag

( string ) optional – the shortcode used

Returns

string nothing is generated directly by this shortcode
