Hi,
You have to use wc_settings_tab_order_export hook. See example below, I have shuffled order of Order status and Phone number.
function shuffle_order($a) {
return $settings = array(
'section_title' => array(
'name' => __( 'WooCommerce Order Export', 'woocommerce-simply-order-export' ),
'type' => 'title',
'desc' => '',
'id' => 'wc_settings_tab_orderexport_section_title'
),
'short_desc' => array(
'type' => 'short_desc',
'desc' => __( 'Please choose settings for order export.', 'woocommerce-simply-order-export' ),
),
'customer_name' => array(
'name' => __( 'Customer Name', 'woocommerce-simply-order-export' ),
'type' => 'checkbox',
'desc' => __( 'Customer Name', 'woocommerce-simply-order-export' ),
'id' => 'wc_settings_tab_customer_name'
),
'product_info' => array(
'name' => __( 'Items Purchased', 'woocommerce-simply-order-export' ),
'type' => 'checkbox',
'desc' => __( 'Export product details.', 'woocommerce-simply-order-export' ),
'id' => 'wc_settings_tab_product_info'
),
'amount' => array(
'name' => __( 'Amount', 'woocommerce-simply-order-export' ),
'type' => 'checkbox',
'desc' => __( 'Amount paid by customer', 'woocommerce-simply-order-export' ),
'id' => 'wc_settings_tab_amount'
),
'email' => array(
'name' => __( 'Email', 'woocommerce-simply-order-export' ),
'type' => 'checkbox',
'desc' => __( 'Email of customer', 'woocommerce-simply-order-export' ),
'id' => 'wc_settings_tab_customer_email'
),
'status' => array(
'name' => __( 'Status', 'woocommerce-simply-order-export' ),
'type' => 'checkbox',
'desc' => __( 'Order Status', 'woocommerce-simply-order-export' ),
'id' => 'wc_settings_tab_order_status'
),
'phone' => array(
'name' => __( 'Phone', 'woocommerce-simply-order-export' ),
'type' => 'checkbox',
'desc' => __( 'Phone number of customer', 'woocommerce-simply-order-export' ),
'id' => 'wc_settings_tab_customer_phone'
),
);
}
add_filter('wc_settings_tab_order_export', 'shuffle_order');
Let me know if this helps.
