WooCommerce Checkout Add-ons

Selling add-ons at checkout? Gift wrapping, donation options, or custom messages?

Standard exports show the fee amount. Not what the customer actually selected.

Here’s how to export the add-on values themselves.

What this code does

Exports checkout add-on selections as separate columns.

Example: You offer “Student Name”, “Student Grade Level”, and “Teacher Name” fields during checkout. Each becomes its own column.

The complete code

// "Checkout Add-ons" plugin
class WOE_Checkout_Addons_Mod {
	var $fields = array('Student Name','Student Grade Lavel','Teacher Name');// edit this line!!
	function __construct() {
		add_filter('woe_get_order_fields', array($this,'add_order_fields') );
		add_action('woe_order_export_started', array($this,'get_fee_details') );
		add_filter('woe_fetch_order_row', array($this,'fill_new_columns'), 10, 2);
	}
	
	function add_order_fields($fields) {
		foreach($this->fields as $pos=>$name) {
			$fields['fee_addon_'.$pos] = array('segment'=>'other','label'=>$name, 'colname'=>$name,'checked'=>1);
		}	
		return $fields;
	}
	
	function get_fee_details($order_id) {
		$this->fee_data = array();
		
		$order = new WC_Order($order_id);
		foreach($order->get_items("fee") as $item_id=>$item) {
			$pos = array_search($item['name'],$this->fields);
			if( $pos  !== false) {
				$item_meta = $order->get_item_meta( $item_id );
				$this->fee_data[$pos] = join(", ", $item_meta['_wc_checkout_add_on_value']); // many values?
			}
		}
		return $order_id; 
	}
	
	// add new values to row
	function fill_new_columns($row,$order_id) {
		foreach($this->fields as $pos=>$name) {
			if(isset($row['fee_addon_'.$pos]) AND isset($this->fee_data[$pos]) )
				$row['fee_addon_'.$pos] = $this->fee_data[$pos] ;
		}		
		return $row;
	}
}
new WOE_Checkout_Addons_Mod();

// "Checkout Add-ons" plugin

class WOE_Checkout_Addons_Mod {

var $fields = array('Student Name','Student Grade Lavel','Teacher Name');// edit this line!!

function __construct() {

add_filter('woe_get_order_fields', array($this,'add_order_fields') );

add_action('woe_order_export_started', array($this,'get_fee_details') );

add_filter('woe_fetch_order_row', array($this,'fill_new_columns'), 10, 2);

}

function add_order_fields($fields) {

foreach($this->fields as $pos=>$name) {

$fields['fee_addon_'.$pos] = array('segment'=>'other','label'=>$name, 'colname'=>$name,'checked'=>1);

}

return $fields;

}

function get_fee_details($order_id) {

$this->fee_data = array();

$order = new WC_Order($order_id);

foreach($order->get_items("fee") as $item_id=>$item) {

$pos = array_search($item['name'],$this->fields);

if( $pos !== false) {

$item_meta = $order->get_item_meta( $item_id );

$this->fee_data[$pos] = join(", ", $item_meta['_wc_checkout_add_on_value']); // many values?

}

return $order_id;

}

// add new values to row

function fill_new_columns($row,$order_id) {

foreach($this->fields as $pos=>$name) {

if(isset($row['fee_addon_'.$pos]) AND isset($this->fee_data[$pos]) )

$row['fee_addon_'.$pos] = $this->fee_data[$pos] ;

}

return $row;

}

new WOE_Checkout_Addons_Mod();

Setup steps

Edit the fields array to match your actual checkout add-ons:

var $fields = array('Gift Message', 'Delivery Date', 'Gift Wrap Color');

1	var $fields = array('Gift Message', 'Delivery Date', 'Gift Wrap Color');

Use the exact names from your checkout add-ons.

Copy the code into your theme’s functions.php
Go to Advanced Order Export for WooCommerce
Create or edit an export profile
Open Setup Fields → Others
You’ll see your add-on fields. Check the ones you need
Save and test on an order with checkout add-ons

What your export looks like

Order #	Order Total	Student Name	Student Grade Level	Teacher Name
1001	$150.00	Sarah Johnson	5th Grade	Ms. Davis
1002	$89.00	Mike Chen	3rd Grade	Mr. Wilson

Each add-on field has its own column.

Real examples

Gift store:

var $fields = array('Gift Message', 'Gift Wrap Option', 'Delivery Date');

1	var $fields = array('Gift Message', 'Gift Wrap Option', 'Delivery Date');

Restaurant ordering:

php

var $fields = array('Special Instructions', 'Allergy Notes', 'Pickup Time');

Event registration:

var $fields = array('Attendee Name', 'Dietary Restrictions', 'Emergency Phone');

1	var $fields = array('Attendee Name', 'Dietary Restrictions', 'Emergency Phone');

When you need this

You sell personalized products. Need customer input in your export.

You run a restaurant. Need special instructions and allergy notes.

Your team fulfills orders manually. Need all add-on details in one place.

How it works

Checkout Add-ons stores customer selections as fee items. Each add-on becomes a fee line.

The code finds those fees. Matches them by name. Pulls the value from _wc_checkout_add_on_value meta. Puts each into its own column.

Common mistake

Field names must match exactly. “Student Name” won’t match “student name” or “StudentName”.

Check your checkout page. Copy the exact label text. Paste into the $fields array.

Empty columns?

Three things to check:

Did the customer actually fill out that add-on?
Does the add-on name match exactly?
Is the Checkout Add-ons plugin active?

Multiple values for one add-on

Some add-ons allow multiple selections (checkboxes). The code joins them with commas.

Example: “Red, Blue, Green” in one cell.

Pro tip

Add more fields as needed. Just add new names to the $fields array.

var $fields = array('Field 1', 'Field 2', 'Field 3', 'Field 4', 'Field 5');

1	var $fields = array('Field 1', 'Field 2', 'Field 3', 'Field 4', 'Field 5');

No other changes needed. The code handles any number of fields.

Real talk

Checkout Add-ons stores data differently than regular order meta. This code digs into fee items where the data lives.

Your fulfillment team gets clear instructions. No more “what did the customer write in that box?” Guesswork eliminated.
