Récupérer la valeur d'une variable d'un plugin pour l'afficher dans un autre plugin

Bonjour à tous :),

je vais tenter de vous expliquer simplement ce que je souhaiterais faire à partir de 2 plugins wordpress : Woocommerce et Gaugepress.

Je souhaiterais utiliser la valeur d'une variable donné par Woocommerce pour l'utiliser dans Gaugespress :

http://img11.hostingpics.net/pics/304497value.png

Woocommerce (script de ecommerce) m'affiche dans la partie admin de mon site tout un ensemble de statistiques et en particulier le nombre total de vente que j'ai réalisé (c'est la valeur de cette variable $order_items qui m'interesse).

Pour cela, il me semble que wordpress utilise la requête sql suivante :

Code:

1

10
11
12

14
	$order_items = apply_filters( 'woocommerce_reports_sales_overview_order_items', absint( $wpdb->get_var( "
		SELECT SUM( order_item_meta.meta_value )
		FROM {$wpdb->prefix}woocommerce_order_items as order_items
		LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta ON order_items.order_item_id = order_item_meta.order_item_id
		LEFT JOIN {$wpdb->posts} AS posts ON order_items.order_id = posts.ID
		LEFT JOIN {$wpdb->term_relationships} AS rel ON posts.ID = rel.object_ID
		LEFT JOIN {$wpdb->term_taxonomy} AS tax USING( term_taxonomy_id )
		LEFT JOIN {$wpdb->terms} AS term USING( term_id )
		WHERE 	term.slug IN ('" . implode( "','", apply_filters( 'woocommerce_reports_order_statuses', array( 'completed', 'processing', 'on-hold' ) ) ) . "')
		AND 	posts.post_status 	= 'publish'
		AND 	tax.taxonomy		= 'shop_order_status'
		AND 	order_items.order_item_type = 'line_item'
		AND 	order_item_meta.meta_key = '_qty'
	" ) ) );

Je souhaiterais donc récuperer la valeur de cette variable $order_items pour l'utiliser afin de déterminer la valeur de la variable $value de Gaugepress.
Je vous mets le script plugin.php de Gaugepress :
