PHP WP_Theme::get_allowed_on_network方法代码示例

/**
 * Returns an array of WP_Theme objects based on the arguments.
 *
 * Despite advances over get_themes(), this function is quite expensive, and grows
 * linearly with additional themes. Stick to wp_get_theme() if possible.
 *
 * @since 3.4.0
 *
 * @param array $args The search arguments. Optional.
 * - errors      mixed  True to return themes with errors, false to return themes without errors, null
 *                      to return all themes. Defaults to false.
 * - allowed     mixed  (Multisite) True to return only allowed themes for a site. False to return only
 *                      disallowed themes for a site. 'site' to return only site-allowed themes. 'network'
 *                      to return only network-allowed themes. Null to return all themes. Defaults to null.
 * - blog_id     int    (Multisite) The blog ID used to calculate which themes are allowed. Defaults to 0,
 *                      synonymous for the current blog.
 * @return Array of WP_Theme objects.
