wp_get_themes() WP 1.0

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.

  • Global. Array. $wp_theme_directories
  • Static. Array. $_themes

No Hooks.

Return

Array. Array of WP_Theme objects.

Usage

wp_get_themes( $args );
$args(array)

The search arguments. Optional.

  • errors mixed True to return themes with errors, false to return themes without errors, null to return all themes.
  • 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.

Default: false
