Hide product unless user has specific product and amount in cart

Hi, it’s me, again,

I managed to make it work, after 10 minutes. I was sure I couldn’t do it yesterday, but ah, fresh mind..

You can hide a product, or multiple, using ID’s. Check out the following snippet:

function custom_pre_get_posts_query( $q ) {

    // Read cart contents

    // Get ids of products which you want to hide
    $array_of_product_id = array(3139);

    $q->set( 'post__not_in', $array_of_product_id );

add_action( 'woocommerce_product_query', 'custom_pre_get_posts_query' );
