function get_usermeta( $user_id, $meta_key = '' ) {}

Retrieve user metadata.
If $user_id is not a number, then the function will fail over with a ‘false’ boolean return value. Other returned values depend on whether there is only one item to be returned, which be that single item type. If there is more than one metadata value, then it will be list of metadata values.


  • int $user_id: User ID
  • string $meta_key: Optional. Metadata key.

Source code

function get_usermeta( $user_id, $meta_key = '' ) {

	_deprecated_function( __FUNCTION__, '3.0', 'get_user_meta()' );

	global $wpdb;

	$user_id = (int) $user_id;

	if ( !$user_id )

		return false;

	if ( !empty($meta_key) ) {

		$meta_key = preg_replace('|[^a-z0-9_]|i', '', $meta_key);

		$user = wp_cache_get($user_id, 'users');

		// Check the cached user object

		if ( false !== $user && isset($user->$meta_key) )

			$metas = array($user->$meta_key);


			$metas = $wpdb->get_col( $wpdb->prepare("SELECT meta_value FROM $wpdb->usermeta WHERE user_id = %d AND meta_key = %s", $user_id, $meta_key) );

	} else {

		$metas = $wpdb->get_col( $wpdb->prepare("SELECT meta_value FROM $wpdb->usermeta WHERE user_id = %d", $user_id) );


	if ( empty($metas) ) {

		if ( empty($meta_key) )

			return array();


			return '';


	$metas = array_map('maybe_unserialize', $metas);

	if ( count($metas) == 1 )

		return $metas[0];


		return $metas;
