Set brand property (pa_brand) for all products

We use the following code to programmatically set the pa_brand (German: Marke) property for all products at once.

add_action('admin_init', 'iphf_add_brand_for_all_products');
function iphf_add_brand_for_all_products() {
	$queryArgs = array(
		 'post_type' => 'product',
		 'posts_per_page' => -1
	);

	$my_query = new WP_Query( $queryArgs );

	if( $my_query->have_posts() ) {

	   while ($my_query->have_posts()) : $my_query->the_post(); 

		 $term_taxonomy_ids = wp_set_object_terms( get_the_ID(), 'mein-marke', 'pa_brand', true );
		 $thedata = Array('pa_brand'=>Array(
		   'name'=>'pa_brand',
		   'value'=>'meine-marke',
		   'is_visible' => '1',
		   'is_taxonomy' => '1'
		 ));
		 update_post_meta( get_the_ID(),'_product_attributes', $thedata); 

	   endwhile;
	}

	wp_reset_query();
}

With is_visible a 1 (true) comes when the brand is to be displayed on the product page as “additional information”. If not required, then insert 0. My brand (in bold in the code) must be replaced by the title form (slug) of the brand. The value for the title form can be found in the editing mask of the property (Products -> Properties -> Configure terms at brand and then edit at the corresponding brand).

It is important to remove this code after execution so that the code is not executed every time the admin area is loaded and loading is delayed.
