在 WooCommerce 中调用 boolean 上的成员函数 get_items() 谢谢 [英] Call to a member function get_items() on boolean in WooCommerce thankyou

问题描述

我正在尝试获取订单详细信息以在我的感谢页面上显示摘要.我遇到的问题是我拥有的这段代码正在破坏我的 wordpress.我有堆栈跟踪，但我不确定如何修复它.对我来说，代码看起来是正确的，所以请确保它不工作的原因.有没有人知道这个堆栈跟踪的含义是什么以及我如何解决它?

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 stacktrace but I am unsure on how to fix it. The code to me looks correct so ensure why it's not working. Does anybody have any idea what is the meaning of this stacktrace and how I can fix it?

   An error of type E_ERROR was caused in line 7 of the file /home4/xxx/public_html/staging/4326/wp-content/plugins/code-snippets/php/snippet-ops.php(446) : eval()'d code. Error message: Uncaught Error: Call to a member function get_items() on boolean in /home4/xxx/public_html/staging/4326/wp-content/plugins/code-snippets/php/snippet-ops.php(446) : eval()'d code:7
    Stack trace:

我的代码:

My code:

function order_table_summary(){
    
    $order = wc_get_order($order_id);
    
    // Get and Loop Over Order Items
    foreach ( $order->get_items() as $item_id => $item ) {

        echo $item->get_name() . $item->get_quantity. $item->get_total();
    }
}
add_shortcode('order_table_summary', 'order_table_summary');

更新 添加短代码

推荐答案

变量$order_id未定义，$item->get_quantity需要为$item->get_quantity() 并且输出不应与短代码一起回显，始终返回.

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.

此短代码用于订单接收页面

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
    }
}

代码位于活动子主题(或活动主题)的functions.php 文件中.经测试有效.

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

用法:

• [order_table_summary]
• 或者在 PHP 代码中:echo do_shortcode('[order_table_summary]');

仅用于测试:

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