get_metadata() WP 1.0

Retrieve metadata for the specified object.

If the meta field exists, a single value is returned if $single is true, or an array of values if it's false.

If the meta field does not exist, the result depends on get_metadata_default(). By default, an empty string is returned if $single is true, or an empty array if it's false.

Возвращает

Mixed. Single metadata value, or array of values. False if there's a problem with the parameters passed to the function.
