Call to a member function get_items() on boolean in WooCommerce thankyou

Question

I am trying to get order details to display a summary on my thank you page. The issue I am having is that this code snippet I have is breaking my wordpress. I have the stacktrac

Answer 1

The variable $order_id is not defined, $item->get_quantity need to be $item->get_quantity() and the output should never be echoed with a shortcode, always returned.

This shortcode is to be used on Order received page

add_shortcode('order_table_summary', 'display_order_table_summary_thankyou');

function display_order_table_summary_thankyou(){
    global $wp;

    // If order_id is defined on Order reveived / thankyou page
    if ( is_wc_endpoint_url('order-received')
    && isset($wp->query_vars['order-received'])
    && absint($wp->query_vars['order-received']) > 0 ) {

        // Get the WC_Order Object
        $order = wc_get_order( absint($wp->query_vars['order-received']) );

        ob_start(); // Start buffering

        echo '<table><tr>
            <th>' . __("Product name", "woocommerce") . '</th>
            <th>' . __("Quantity", "woocommerce") . '</th>
            <th>' . __("Line total", "woocommerce") . '</th>
        </tr>';

        // Loop Over Order Items
        foreach ( $order->get_items() as $item ) {
            echo '<tr>
            <td>' . $item->get_name() . '</td>
            <td>' . $item->get_quantity() . '</td>
            <td>' . $item->get_total() . '</td>
            </tr>';
        }

        echo '</table>';

        return ob_get_clean(); // Return the buffered content
    }
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.

USAGE:

• [order_table_summary]
• or also inside PHP code: echo do_shortcode('[order_table_summary]');

Just for testing:

add_action( 'woocommerce_thankyou', 'testing_shorcode' );
function testing_shorcode() {
    echo do_shortcode('[order_table_summary]');
}
