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.

No Hooks.

Return

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

Usage

get_metadata( $meta_type, $object_id, $meta_key, $single );

$meta_type(string) (required)

Type of object metadata is for. Accepts 'post', 'comment', 'term', 'user', or any other object type with an associated meta table.

$object_id(int) (required)

$meta_key(string)

Metadata key. If not specified, retrieve all metadata for the specified object.
