On purchase/checkout of an item(s) via Woocommerce, My checkout code includes 2 hidden fields that sends default post meta value saved under _dispatch and _dispatch_driver.
This post meta feeds a select field with the first values in the admin side of order item.
I have custom post types with information that should feed the select options fields as the other options.
My issues are on the admin side when the order item is opened.
- The default information is set well but I can seem to save/change the second select field on clicking the update button.
- I can not feed the woocommerce options fields with my values from the CPT queries I have done.
Code made partially from: Custom editable field in Woocommerce admin edit order pages general section
add_action( 'woocommerce_checkout_update_order_meta', 'save_custom_checkout_field'), 10, 1 );
add_action('woocommerce_admin_order_data_after_order_details', 'editable_order_custom_field', 10, 1 );
add_action( 'woocommerce_process_shop_order_meta', 'save_order_custom_field_meta_data', 12, 2 );
//Then you will need to save this hidden field in the order, this way:
function save_custom_checkout_field( $order_id ) {
if ( ! empty( $_POST['dispatch'] ) )
update_post_meta( $order_id, '_dispatch', sanitize_text_field( $_POST['dispatch'] ) );
if ( ! empty( $_POST['dispatch_driver'] ) )
update_post_meta( $order_id, '_dispatch_driver', sanitize_text_field( $_POST['dispatch_driver'] ) );
}
// Output a custom editable field in backend edit order pages under general section
function editable_order_custom_field( $order ){
// Loop through order items
foreach( $order->get_items() as $item_id => $item ){
// Get "customer reference" from order item meta data
if( $item->get_meta('_dispatch') ){
// The "customer reference"
$item_value = $item->get_meta('_dispatch');
// We output a hidden field with the Item ID (to be able to update this order item meta data later)
echo '<input type="hidden" name="item_id" value="' . $item_id . '">';
break; // We stop the loop
}
if( $item->get_meta('_dispatch_driver') ){
// The "customer reference"
$item_value_ref = $item->get_meta('_dispatch_driver');
// We output a hidden field with the Item ID (to be able to update this order item meta data later)
echo '<input type="hidden" name="item_id_ref" value="' . $item_value_ref . '">';
break; // We stop the loop
}
}
// Get "customer reference" from meta data (not item meta data)
$dispatch_updated_value = $order->get_meta('_dispatch');
$dispatch_driver_updated_value = $order->get_meta('_dispatch_driver');
// Replace "dispatch reference" value by the meta data if it exist
$dispatch_new_value = $dispatch_updated_value ? $dispatch_updated_value : ( isset($item_value) ? $item_value : '');
$dispatch_driver_new_value = $dispatch_driver_updated_value ? $dispatch_driver_updated_value : ( isset($item_value_ref) ? $item_value_ref : '');
$variable = $data_dispatches )[0];
// Display the custom editable field

This is the code for saving the initial details in checkout phase
function register() {
add_action( 'woocommerce_after_order_notes', array( $this, 'my_custom_checkout_field' ), 10, 1 );
add_action( 'woocommerce_checkout_update_order_meta', array( $this, 'save_custom_checkout_field'), 10, 1 );
}
//Then you will need to save this hidden field in the order, this way:
function my_custom_checkout_field( $checkout ) {
$dispatch = 'Unassigned Dispatch No';
$dispatch_driver = 'Unassigned Driver';
// Output the hidden link
echo '
<div id="dispatch_checkout_field">
<input type="hidden" class="input-hidden" name="dispatch" id="dispatch" value="' . $dispatch . '">
</div>
<div id="dispatch_driver_checkout_field">
<input type="hidden" class="input-hidden" name="dispatch_driver" id="dispatch_driver" value="' . $dispatch_driver . '">
</div>
';
}
//Then you will need to save this hidden field in the order, this way:
function save_custom_checkout_field( $order_id ) {
if ( ! empty( $_POST['dispatch'] ) )
update_post_meta( $order_id, '_dispatch', sanitize_text_field( $_POST['dispatch'] ) );
if ( ! empty( $_POST['dispatch_driver'] ) )
update_post_meta( $order_id, '_dispatch_driver', sanitize_text_field( $_POST['dispatch_driver'] ) );
}
