Good morning. I need to move the prices contained in the cards above the titles in the main shop pages and consequently the category too. I mean not the single page where you see the product itself, but the /shop page where all the products are listed. i don't really know the hook to use and priority to set. Thank you for your help.
It depends on your theme, but if everything is by default, this is the code you need:
add_action( 'woocommerce_before_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );
remove_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );
Code goes in functions.php file of your active theme/child theme. Tested and works.
