bw_query_taxonomy_value() – Determine the tag or category value to use if the given value is not a tag or category slug

Description

Determine the tag or category value to use if the given value is not a tag or category slug

The rules for tag and category slugs are… that they are usually all lowercase and contains only letters, numbers, and hyphens. So if we find a period then we can consider it to be a field reference But we need to convert the field value into a tag slug! Note: If the tag is numeric or comma separated then we'll not do any lookup

Usage

bw_query_taxonomy_value( $fieldorvalue );

Parameters

$fieldorvalue

( mixed ) required –

Returns

void
