Jason Wong on "[Plugin: WooCommerce] How to make Custom fields displayed in Admin Order editable?"

Yahoo! I managed to get it to what I want, as shown here, with the following codes.

// Extra Shipping fields
function wc_extra_shipping_fields( $fields ) { $fields['shipping_email'] = array( 'label' => __( 'Email Address', 'woocommerce' ), 'required' => true, // 'placeholder' => _x( 'Email', 'placeholder', 'woocommerce' ), 'class' => array( 'form-row-first' ), 'validate' => array( 'email' ) ); $fields['shipping_phone'] = array( 'label' => __( 'Phone', 'woocommerce' ), 'required' => true, // 'placeholder' => _x( 'Phone', 'placeholder', 'woocommerce' ), 'class' => array( 'form-row-last' ), 'validate' => array( 'phone' ), 'clear' => true ); retu $fields;
}
add_filter( 'woocommerce_shipping_fields' , 'wc_extra_shipping_fields' );
// Extra Shipping fields in Admin Order Meta
function wc_extra_admin_shipping_fields( $fields ) { global $theorder; $fields['email'] = array( 'label' => __( 'Email', 'woocommerce' ), 'value' => get_post_meta( $theorder->id, '_shipping_email', true ), 'validate' => array( 'phone' ), ); $fields['phone'] = array( 'label' => __( 'Phone', 'woocommerce' ), 'value' => get_post_meta( $theorder->id, '_shipping_phone', true ), 'validate' => array( 'phone' ), 'clear' => true ); retu $fields;
}
add_filter( 'woocommerce_admin_shipping_fields', 'wc_extra_admin_shipping_fields' );

I just hope nothing is amiss ... (--)"
