(WordPress/WooCommerce) Add custom product field and download link to be used manually via PHP

Hello,

I have a WordPress website that runs WooCommerce and sells shipping labels.

Each shipping label is unique. Every time the customer wishes to buy a label, a new product is generated in WooCommerce via PHP. The item is marked as 'virtual' and 'downloadable', so that the user can download their file (shipping label) once the purchase is made. I'm able to generate new items without any problems, however I'm having trouble passing the shipment information through.

I need to be able to pass an extra variable, called "shipment_id", that gets created at the same time as the item gets generated during shopping. The variable needs to get attached to the item. I need to retrieve that variable once payment is confirmed on the "Order Received / Thank You" page , so that I can use some PHP code to retrieve the appropriate label for each item.

Once the label is retrieved, I need to be able to update the download link for each item.

------------------------------

Short Description:

1. Show examples on how to add and retrieve a custom WooCommerce product field via PHP (let's call it shipment_id).

2. Create code to be able to set and retrieve a WooCommerce product download link

These are probably the templates that you'll need to modify:

[url removed, login to view]

[url removed, login to view]

[url removed, login to view]

(probably others?)

Here's the sample code that creates a unique item via PHP:

$my_post = array(

'post_title' => 'USPS Priority Mail or Fedex or something',

'post_content' => 'Description of the item goes here',

'post_status' => 'publish',

'post_author' => 1,

'post_type' =>'product'

);

// Insert the post into the database

$product_ID = wp_insert_post( $my_post );

if ( $product_ID ){

// Basic product info

add_post_meta($product_ID, '_regular_price', $rate->rate );

add_post_meta($product_ID, '_price', $rate->rate );

add_post_meta($product_ID, '_stock_status', 'instock' );

// Only allow one copy of each unique shipping label per cart

add_post_meta($product_ID, '_sold_individually', 'yes' );

// Make product downloadable

add_post_meta($product_ID, '_virtual', 'yes' );

add_post_meta($product_ID, '_downloadable', 'yes' );

// Set temporary product download url

(Your code goes here)

I've tried this code but it doesn't seem to work:

add_post_meta($product_ID, '_wc_file_names', 'Download Link' );

add_post_meta($product_ID, '_wc_file_urls[]', '[url removed, login to view]' );

add_post_meta($product_ID, '_download_expiry', 7 );

I'm looking for someone who can complete this project within the next 24 hours. Full payment upon completion and code tested and verified. Add "Postage123" in the beginning of your bid to let me know you've read the project, understand it, and can complete it.
