我正在使用此代码添加管理操作以更改批量订单状态。我有名为“wc-to-order”的自定义构建状态。不幸的是，使用 Woo 批量操作中的代码时出现错误。谁能帮我解决？

这是代码：

add_action( 'admin_action_wc-to-order', 'add_new_order_status_wc_on_hold' ); // admin_action_{action name}
function add_new_order_status_wc_on_hold() {
 
    // if an array with order IDs is not presented, exit the function
    if( !isset( $_REQUEST['post'] ) && !is_array( $_REQUEST['post'] ) )
        return;
 
    foreach( $_REQUEST['post'] as $order_id ) {
 
        $order = new WC_Order( $order_id );
        $order_note = 'That\'s what happened by bulk edit:';
        $order->update_status( 'wc-to-order', $order_note, true ); 
 
    }
 
    
    $location = add_query_arg( array(
        'post_type' => 'shop_order',
        'wc-to-order' => 1, // markED_awaiting_shipment=1 is just the $_GET variable for notices
        'changed' => count( $_REQUEST['post'] ), // number of changed orders
        'ids' => join( $_REQUEST['post'], ',' ),
        'post_status' => 'all'
    ), 'edit.php' );
 
    wp_redirect( admin_url( $location ) );
    exit;
 
}

我在调试日志中得到了这个

  PHP Fatal error:  Uncaught TypeError: join(): Argument #2 ($array) must be of type ?array, string given in /public_html/sitename/wp-content/themes/themename/functions.php:648

【解决方案1】：

从日志看来，$_REQUEST['post'] 可能不是一个数组。在下面的代码中，我们首先检查它是否是一个数组。如果不是，那么我们将其转换为数组。

add_action( 'admin_action_wc-to-order', 'add_new_order_status_wc_on_hold' ); // admin_action_{action name}
function add_new_order_status_wc_on_hold() {

// if an array with order IDs is not presented, exit the function
if( !isset( $_REQUEST['post'] ) ) {
   return;
}
 
//check if it is an array. If not, cast it as array
$orders_array = is_array($_REQUEST['post']) ? $_REQUEST['post'] : array($_REQUEST['post']);

     foreach( $orders_array as $order_id ) {
 
        $order = new WC_Order( $order_id );
        $order_note = 'That\'s what happened by bulk edit:';
        $order->update_status( 'wc-to-order', $order_note, true ); 
 
    }
 
    
    $location = add_query_arg( array(
        'post_type' => 'shop_order',
        'wc-to-order' => 1, // markED_awaiting_shipment=1 is just the $_GET variable for notices
        'changed' => count( $orders_array ), // number of changed orders
        'ids' => join( $orders_array, ',' ),
        'post_status' => 'all'
    ), 'edit.php' );
 
    wp_redirect( admin_url( $location ) );
    exit;
 
}

这样我们确保数组总是提供给join函数。
