Custom Function for WordPress

Make Fields Required or Optional on the WooCommerce Checkout Page

Hello Fiends, Today I received a message from my client she want to customized (Billing and Shipping) Checkout Page. She have some requirements as bellow mentioned.

Shipping Address Checked Automatic

When we use Default Shipping Address in Woo commerce setting then shipping address automatic checked then customer need to unchecked it otherwise filled their address two time. Here I am writing a line of code it will fixed this problem.

Goto –> Appearance –> Theme File Editor 

open function file add this code

/*Remove CHecked Automatic Shipping different address While you select default shipping address*/
add_filter( ‘woocommerce_ship_to_different_address_checked’, ‘__return_false’ );

Optional Email Address

By default email address is mandatory in Woo Commerce Billing form But My client needed its optional. Here I am also writing code.

Goto –> Appearance –> Theme File Editor 

open function file add this code

/*optional Email in Billing*/
add_filter( ‘woocommerce_billing_fields’, ‘ts_require_wc_company_field’);
function ts_require_wc_company_field( $fields ) {
$fields[‘billing_email’][‘required’] = false;
return $fields;
}

The code snippet below  for Phone enables you to do the same:

add_filter( ‘woocommerce_billing_fields’, ‘ts_unrequire_wc_phone_field’);
function ts_unrequire_wc_phone_field( $fields ) {
$fields[‘billing_phone’][‘required’] = false;
return $fields;
}

You can edit filed name which you want to make required or optional. filed name list is here
