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.

Seeing your edit based on the suggested method from cjbj, make sure you are using the actual directory name for the parent theme when calling wp_get_theme(). Note - this is not the slug or written name of the theme in many cases.

If sometheme is the file directory for the parent theme, then this should return the parent theme object:

var_dump( wp_get_theme( 'sometheme' ) );

Within that theme object is the version. Let's make sure you are getting the parent theme returned first.

Add your output for that var_dump() statement to your question if it is not the parent 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;
