[Plugin: CMS Tree Page View] Bugfix -> insert

Hi!

Just a little bugfix. When inserting a page into the structure it always gets added in first place with menu_order=0. This breaks up the menu-ordering if there are other pages with menu_order=0 in the same place.

Old part of code (functions.php, ~ line 960)

if ( "inside" == $type ) {

			// post_node is moved inside ref_post_node
			// add ref_post_node as parent to post_node and set post_nodes menu_order to 0
			// @todo: shouldn't menu order of existing items be changed?
			$post_to_save = array(
				"ID" => $post_node->ID,
				"menu_order" => 0,
				"post_parent" => $post_ref_node->ID
			);
			wp_update_post( $post_to_save );

			echo "did inside";

		}

New

if ( "inside" == $type ) {

			// post_node in first place, so order=0
			// update menu_order of all pages with parent ref_node_post to keep order clean - only if there is an item with order 0
			$min = $wpdb->get_results( $wpdb->prepare("SELECT MIN(menu_order) AS \"min\" FROM $wpdb->posts WHERE post_parent = %d", $post_ref_node->ID) );
			if($min[0]->min==0) $wpdb->query( $wpdb->prepare( "UPDATE $wpdb->posts SET menu_order = menu_order+1 WHERE post_parent = %d", $post_ref_node->ID ) );

			// post_node is moved inside ref_post_node
			// add ref_post_node as parent to post_node and set post_nodes menu_order to 0
			$post_to_save = array(
				"ID" => $post_node->ID,
				"menu_order" => 0,
				"post_parent" => $post_ref_node->ID
			);
			wp_update_post( $post_to_save );

			echo "did inside";

		}
