Dynamically added custom fields not displayed on WooCommerce email notifications - php

Question

I have a different kind of scenario then the typical custom fields (I suppose). I am not getting custom values (fields) from user in the form rather I have an implementation which adds:
ColorName
Size
City
These are from a custom product flow which adds custom attributes to the cart, here is how I am doing that:
add_action('wp_ajax_wdm_add_user_custom_data_options', 'wdm_add_user_custom_data_options_callback');
add_action('wp_ajax_nopriv_wdm_add_user_custom_data_options', 'wdm_add_user_custom_data_options_callback');
function wdm_add_user_custom_data_options_callback()
{
// print_r($_POST);
$productIDM = $_POST['product_id'];
// case swith
switch ($productIDM) {
case "Ace Dura Silk":
$productID = 3254;
break;
case "Ace Matt Finish":
$productID = 3232;
break;
case "Ace Plastic Emulsion":
$productID = 3276;
break;
case "Ace Weather Defender":
$productID = 2991;
break;
case "Overall Plasticoat":
$productID = 3112;
break;
}
$colorname = $_POST['colorname'];
$cityname = $_POST['cityname'];
$size = $_POST['size'];
$price = $_POST['price'];
global $woocommerce;
$woocommerce->cart->add_to_cart( $productID, 1 );
// die();
// echo 'I am in...';
$result = array(
'status' => true
);
echo json_encode($result);
}
add_filter('woocommerce_add_cart_item_data','wdm_add_item_data',1,10);
function wdm_add_item_data($cart_item_data, $product_id) {
global $woocommerce;
$new_value = array();
$new_value['_custom_options'] = $_POST['custom_options'];
if(empty($cart_item_data)) {
return $new_value;
} else {
return array_merge($cart_item_data, $new_value);
}
}
add_filter('woocommerce_get_cart_item_from_session', 'wdm_get_cart_items_from_session', 1, 3 );
function wdm_get_cart_items_from_session($item,$values,$key) {
if (array_key_exists( '_custom_options', $values ) ) {
$item['_custom_options'] = $values['_custom_options'];
}
return $item;
}
add_filter('woocommerce_cart_item_name','add_usr_custom_session',1,3);
function add_usr_custom_session($product_name, $values, $cart_item_key ) {
$return_string = $product_name . "<div class='cart_subitems_custom'><br /><small>".$values['_custom_options']['colorname']."</small><br /><small>".$values['_custom_options']['cityname']."</small><br /><small>".$values['_custom_options']['size']."</small></div>" ; //. "<br />" . print_r($values['_custom_options']);
return $return_string;
}
add_action('woocommerce_add_order_item_meta','wdm_add_values_to_order_item_meta',1,2);
function wdm_add_values_to_order_item_meta($item_id, $values) {
global $woocommerce,$wpdb;
wc_add_order_item_meta($item_id,'_colorname',$values['_custom_options']['colorname']);
wc_add_order_item_meta($item_id,'_cityname',$values['_custom_options']['cityname']);
wc_add_order_item_meta($item_id,'_size',$values['_custom_options']['size']);
}
add_action( 'woocommerce_before_calculate_totals', 'update_custom_price', 1, 1 );
function update_custom_price( $cart_object ) {
foreach ( $cart_object->cart_contents as $cart_item_key => $value ) {
// Version 2.x
//$value['data']->price = $value['_custom_options']['custom_price'];
// Version 3.x / 4.x
if($value['_custom_options']['price'] == null){
echo"";
}else{
$value['data']->set_price($value['_custom_options']['price']);
}
}
}
I am getting these custom values almost everywhere except Email Notification.
Here is what normal product order edit shows:
Here is how I am getting the custom product in order edit page:
I have tried all the solution I can possibly find (filter & action hooks) but nothing works for me.
I have tried first answer from this:
add_action( 'woocommerce_checkout_create_order_line_item', 'custom_checkout_create_order_line_item', 20, 4 );
function custom_checkout_create_order_line_item( $item, $cart_item_key, $values, $order ) {
if( isset( $values['colorname'] ) )
$item->add_meta_data( __('DCM Shade'), $values['_colorname'] );
}
Also the common method I found everywhere:
function custom_woocommerce_email_order_meta_fields( $fields, $sent_to_admin, $order ) {
// Get meta
$color = $order->get_meta( 'colorname', true );
// NOT empty
if( ! empty( $color ) ) {
$fields['colorname'] = array(
'label' => __( 'Shade' ),
'value' => $color,
);
}
// Get (other) meta
$shipping_email = $order->get_meta( '_cityname', true );
// NOT empty
if ( ! empty( $shipping_email ) ) {
$fields['_cityname'] = array(
'label' => __( 'City' ),
'value' => $shipping_email,
);
}
return $fields;
}
add_filter( 'woocommerce_email_order_meta_fields', 'custom_woocommerce_email_order_meta_fields', 10, 3 );
But I can't get the custom fields.
What am I doing wrong can please anyone please guide me.
