Get parent theme version

by

How do I get the parent theme’s version in a child theme?

I want to use it when loading the parent theme’s stylesheet.

Here’s how I load the stylesheets in the child theme’s functions.php file:

function sometheme_enqueue_styles() {

  // Get parent theme version
  $parent_theme_version = wp_get_theme()->parent()->get( 'Version' );

  // Load parent theme stylesheet
  wp_enqueue_style( 'sometheme-style', get_template_directory_uri() . '/style.css', array(), $parent_theme_version );

  // Load child theme stylesheet
  wp_enqueue_style( 'sometheme-child-style',
    get_stylesheet_directory_uri() . '/style.css',
    array( 'sometheme-style' ),
    wp_get_theme()->get('Version')
  );

}
add_action( 'wp_enqueue_scripts', 'sometheme_enqueue_styles', 11 );

However, this will use the child theme’s version for both stylesheets…

I have also tried this:

$parent_theme = wp_get_theme('sometheme');
$parent_theme_version = $parent_theme->get( 'Version' );

…and this:

$parent_theme = wp_get_theme(get_template());
$parent_theme_version = $parent_theme->get( 'Version' );

But again, the parent theme version keeps getting the version from the child theme.

Solution

It turns out that both wp_get_theme()->parent()->get( 'Version' ); and wp_get_theme()->parent()->Version; works.

The problem was that the parent theme was using $theme_version = wp_get_theme()->get( 'Version' ); as well, which means that it will use the child themes version.

Since I own the parent theme, I changed the parent theme to wp_get_theme('sometheme')->get( 'Version' ); so that it always uses its own version.

That way, I can use either wp_get_theme()->parent()->get( 'Version' ); or wp_get_theme()->parent()->Version; in the child theme.

In the WP_Theme class, the get method gives you a sanitized theme header. You cannot use it to extract a property. Actually you don’t need to, as you can access it directly like this:

 // get the parent object
 $parent = wp_get_theme()->parent();
 // get parent version
 if (!empty($parent)) $parent_version = $parent->Version;
