我每次尝试查看我的时间提要时都会出现此错误.我不知道代码有什么问题.有人可以帮忙吗?我的代码如下.将首先添加第 134 行，然后添加其余代码

公共函数 do_news_feed($user_id) {$status_objects = $this->get_status_objects($user_id);foreach ( $status_objects as $status ) {?><div class="status_item">第 134 行 -----><?php $user = $this->load_user_object($status->user_id);?><h3><a href="/social/profile-view.php?uid=<?php echo $user->ID; ?>"><?php echo $user->user_nicename;?></a></h3><p><?php echo $status->status_content;?></p>

<?php}}

完整代码

<?php}}}}$query = 新查询；?>

解决方案

只需将 user_id 更改为 user_ID 即可.不要忘记 php 区分大小写

将行 134 更改为 

load_user_object($status->user_ID);?>

Im having this error showing up every time I try to view my time feed. I dont know whats wrong with the code. Can someone help? My code is below. Line 134 will be added first, then the rest of the code

public function do_news_feed($user_id) {
                $status_objects = $this->get_status_objects($user_id);

                foreach ( $status_objects as $status ) {?>
                    <div class="status_item">
    Line 134 ----->  <?php $user = $this->load_user_object($status->user_id); ?>
                        <h3><a href="/social/profile-view.php?uid=<?php echo $user->ID; ?>"><?php echo $user->user_nicename; ?></a></h3>
                        <p><?php echo $status->status_content; ?></p>
                    </div>
                <?php
                }
            }

    $query = new QUERY;
?>

解决方案

just change user_id to user_ID . don't forget php is case sensitive

change line 134 to 

<?php $user = $this->load_user_object($status->user_ID); ?>
