在特定订单状态通知电子邮件中获取自定义post类型id

Question

尝试接收并显示自定义post类型WCFA_Attachmentid以仅在id为WC_ORDER_STATUS_EMAIL_731的订单状态更改通知电子邮件上显示

例如：

$attachments = get_posts( array( 'numberposts' => -1, 'post_parent' => $order_id, 'post_type'=> 'wcfa_attachment', 'order' => 'ASC', 'orderby' => 'ID', 'suppress_filters' => false/*,  'meta_key' => 'wcaf_is_active', 'meta_value' => true */ ));

我能够以wc_order_status_email_731为目标，提取order_id然后显示if用于测试，但不能显示与订单相关联的wcfa_attachment的自定义post类型post ID。

function add_content_specific_email( $order, $sent_to_admin, $plain_text, $email ) {
if ( $email->id == 'wc_order_status_email_731' ) {
   
   $order_id = $order->get_id();

/// works to print the order id so we know its being received
print_r ($order_id);
   
 function get_attachments($order_id)
{
    $result = array();
    
    $attachments = get_posts( array( 'numberposts' => -1, 'post_parent' => $order_id, 'post_type'=> 'wcfa_attachment', 'order' => 'ASC', 'orderby' => 'ID', 'suppress_filters' => false/*,  'meta_key' => 'wcaf_is_active', 'meta_value' => true */ ));
    foreach((array)$attachments as $attachment)
    {
        $result[$attachment->ID] = $this->get_attachment($attachment->ID);  
    }       
    return $result;
    print_r ($result);
}
}
}

您正在查找的post类型ID只是$attachment->ID。

现在，您不应该将一个函数嵌入到另一个函数中。把它们分开就行了。

然后您可以在另一个函数中调用您的函数，如下所示：

function get_attachments( $order_id ) {
    $result = array();
    
    $attachments = get_posts( array( 'numberposts' => -1, 'post_parent' => $order_id, 'post_type'=> 'wcfa_attachment', 'order' => 'ASC', 'orderby' => 'ID', 'suppress_filters' => false/*,  'meta_key' => 'wcaf_is_active', 'meta_value' => true */ ));
    foreach((array)$attachments as $attachment){
        $result[$attachment->ID] = $this->get_attachment($attachment->ID);  
    }
    return $result;
}

function add_content_specific_email( $order, $sent_to_admin, $plain_text, $email ) {
    if ( $email->id == 'wc_order_status_email_731' ) {
       
       $order_id = $order->get_id();
    
        /// works to print the order id so we know its being received
        print_r ($order_id);
        
        $attachments = get_attachments( $order_id ); // Call the function
        
        print_r ($attachments); 
    }
}

它最好能起作用。
