WooCommerce customer order detail in BS Modal

There isn't a single function that I'm aware of that can get all of the order details that you need in one go however you can call WC_Order class to get what you need. Making some calls methods similar to these would get you the info you need. You will likely need to make calls to more than just the get_items() method depending on the exact info you need. Generally they return objects similar in structure to post objects.

$order = new WC_Order($post->ID);
$_order = $order->get_items();

Look here under the 'inherited methods' section to find the methods you might need to call to get all the info you need. https://docs.woocommerce.com/wc-apidocs/class-WC_Order.html

woocommerce_order_details_table( $order_id )

This WooCommerce function returns the full order details in HTML form by $order_id

Here is the complete code to display curent customer orders in a modal window. Its based on a classic query to get current user orders and on the template my-account/orders.php (lightly customized)…

<?php

if(is_user_logged_in()):

    // The query
    $args = array(
        // WC orders post type
        'post_type'   => 'shop_order',
        'numberposts' => -1,
        // for current user id
        'meta_key'    => '_customer_user',
        'meta_value'  => get_current_user_id(),
        // get orders statuses
        'post_status' => array_keys(wc_get_order_statuses()),
    );

    // Get all customer orders
    $customer_orders = get_posts( $args );
    $count_ord = 0;
    if (!empty($customer_orders))
        foreach ( $customer_orders as $custo_order )
            $count_ord++;

    if ( $count_ord > 0 )
        $has_orders = true;
    else
        $has_orders = false;

    // the template my-account/orders.php  ?>

    <?php do_action( 'woocommerce_before_account_orders', $has_orders ); ?>

    <?php if ( $has_orders ) : ?>

You will have to add existing css rules to your modal window and/or customized that css rules.

This code is tested and fully functional.
