Reply To: Change "Add to Cart" text in grid view

Hi,

Try to use this code instead

echo apply_filters( 'woocommerce_loop_add_to_cart_link',
	sprintf( '<a rel="nofollow" href="%s" data-quantity="%s" data-product_id="%s" data-product_sku="%s" class="%s">Text<br>with break</a>',
		esc_url( $product->add_to_cart_url() ),
		esc_attr( isset( $quantity ) ? $quantity : 1 ),
		esc_attr( $product->get_id() ),
		esc_attr( $product->get_sku() ),
		esc_attr( isset( $class ) ? $class : 'button' )
	),
$product );
