How do you make checkout fields optional?

By default, Masteriyo marks specific billing fields as required based on your Settings > Payments > Checkout Fields. If you’d instead let customers skip any of these, you can hook into the masteriyo_checkout_fields filter and clear the required flag.

#Example 1: Make all built-in fields optional

add_filter( 'masteriyo_checkout_fields', 'make_all_fields_optional', 10, 1 );    

function make_all_fields_optional( $fields ) {    

    foreach ( $fields as $key => &$field ) {    

        // turn off the “required” flag    

        $field['required'] = false;    

    }    

    return $fields;   

}

#Example 2: Only make Company and Phone optional

add_filter( 'masteriyo_checkout_fields', 'optional_company_phone', 10, 1 );     
function optional_company_phone( $fields ) {   
    $fields['billing_company']['required'] = false;     
    $fields['billing_phone']['required']   = false;   
        return $fields;    
    }    

#All Available Field Keys

Target any of these keys in your filter to change their required status:

Key	Label
billing_first_name	First name
billing_last_name	Last name
billing_email	Email address (used for account creation and should normally stay required)
billing_country	Country
billing_address_1	Address line 1
billing_address_2	Address line 2
billing_company	Company name
billing_phone	Phone number
billing_city	City
billing_state	State / Province
billing_postcode	Postal / ZIP code
customer_note	Order notes
attachment_upload	File upload
gdpr	GDPR consent checkbox

#Hiding fields entirely

If you don’t just want to make a field optional, but remove it from the form:

add_filter( 'masteriyo_checkout_fields', 'remove_postcode_field', 20, 1 );    
function remove_postcode_field( $fields ) {    
    unset( $fields['billing_postcode'] );    
    return $fields;    
}
