get_terms_fields filter-hook . WP 2.8.0

Filters the fields to select in the terms query.

Field lists modified using this filter will only modify the term fields returned by the function when the $fields parameter set to 'count' or 'all'. In all other cases, the term fields in the results array will be determined by the $fields parameter alone.

Use of this filter can result in unpredictable behavior, and is not recommended.

Usage

add_filter( 'get_terms_fields', 'filter_function_name_4781', 10, 3 );
function filter_function_name_4781( $selects, $args, $taxonomies ){
	// filter...

	return $selects;
}

$selects(string[])

An array of fields to select for the terms query.

$args(array)

An array of term query arguments.

$taxonomies(string[])

An array of taxonomy names.
