How to disable guest checking for all products, untick in the wordpress does not work :(

Hello, How can i do the opposite? How to enable guest checkout for certain products?

Here is the opposite: https://gist.github.com/contemplate/2adc7be2c72d585a07ac6f90b1f1e1b4

• also adds a checkbox on the product to enable guest checkout

How can I do this for a certain woocommerce category, not an array of product ids?

Hi dear friend
this hook «pre_option_woocommerce_enable_guest_checkout» used.
where is woocommerce defined?

I use this code to customize the email on the WooCommerce checkout page:

add_filter( 'woocommerce_billing_fields', 'ts_unrequire_wc_email_field'); function ts_unrequire_wc_email_field( $fields ) { $fields['billing_email']['required'] = false; return $fields; }

How can I specify that if a product needs to be registered, email will be required?

6 years old and still works for me. Thank you!
