Question

我需要从终止订单中检索订单ID。使用此代码时：（我确实只是回应了解......在最终代码中不需要它）

<?php
    $customer_orders = get_posts( array(
                'numberposts' => -1,
                'meta_key'    => '_customer_user',
                'meta_value'  => get_current_user_id(),
                'post_type'   => 'shop_order',
                'post_status' => 'completed',
                    ) );

                 // echo for tests                 
                 echo "<pre>";
                 print_r($customer_orders);
                 echo "</pre>";

                 foreach($customer_orders as $item) {
                 echo the_title();
                 //echo item[ID];   I let this one commented because it doesn't work...but it's what I need !                                       
                    } ?>

我可以清楚地看到我需要的东西：来自[ID] =＆gt;的9570和9559

Array
(
[0] => WP_Post Object
    (
        [ID] => 9570
        [post_author] => 1
        [post_date] => 2016-03-31 13:19:42
        [post_date_gmt] => 2016-03-31 11:19:42
        [post_content] => 
        [post_title] => Order – mars 31, 2016 @ 01:19  
        [post_excerpt] => 
        [post_status] => wc-completed

etc...

[1] => WP_Post Object
    (
        [ID] => 9559
        [post_author] => 1
        [post_date] => 2016-03-28 15:55:27
        [post_date_gmt] => 2016-03-28 13:55:27
        [post_content] => 
        [post_title] => Order – mars 28, 2016 @ 03:55  
        [post_excerpt] => 
        etc....

但是试图检查我需要的值我没有得到任何好处...代码不起作用。我做了很多尝试，但没有任何工作：

echo item[0]; or echo item[ID];

我哪里错了？我需要这两个值才能将它们放在下拉字段中。

感谢您的帮助。

Answer 1

the_title仅适用于The Loop内部，请尝试重构您的代码，如下所示

foreach( $customer_orders as $item ) {

    setup_postdata( $item );

    echo the_title();
    echo the_ID();

    //echo item[ID];   I let this one commented because it doesn't work...but it's what I need !

 }
 wp_reset_postdata();

除非是拼写错误，否则您使用的item[0]或item[ID]不正确，因为@paskl已正确指出，该变量是WP_Post类的对象，以访问其属性您需要使用->运算符，其次您错过了前面的$符号，因此item[0]应为$item[0]
```
foreach( $customer_orders as $item ) {

    echo $item->ID;  //this will work
    echo $item->post_title; // and so will this

}
```

这很好......但是......

 <?php
                        $args = get_posts( array(
                'numberposts' => -1,
                'meta_key'    => '_customer_user',
                'meta_value'  => get_current_user_id(),
                'post_type'   => 'shop_order',                    
                'post_status' => 'completed',
                    ) );

                    foreach($args as $item) {
                    setup_postdata( $item );
                    echo "<pre>";
                    echo the_title() . " - " . $item->post_title . " - Order N&ordm; : " . $item->ID;
                    echo "</pre>";                      
                    }   
                    ?>

它让我感觉像是：

 The Title - Order – avril 1, 2016 @ 05:09   - Order Nº : 9573

 The Title - Order – mars 28, 2016 @ 03:55   - Order Nº : 9559

不幸的是，“标题”不是订单中包含的产品标题，而是我使用该代码的页面标题。
