Question

我正在为我的大学作业做一个项目。除了我的活动列表，其他所有内容都可以正常使用。问题是，每当我尝试查看活动列表时，它仅返回1个活动，而不是所有仍在进行的活动，当我从phpMyAdmin手动运行查询时，它将返回所有查询，但PHP却没有似乎做对了，我也不知道为什么。

我已经尝试过从phpMyAdmin运行查询并简化查询，还添加了一堆调试代码来查看我要去哪里，但所有值均正确，查询正确且{{1 }}运行查询就很好了。

phpMyAdmin

    <?php

    $query = "SELECT * FROM activities"; 
              $result = mysqli_query($link, $query);

              if(!$result) {
                echo "<p class='text-danger'>There are no activities to display.</p>";
              } else {
                while($row = mysqli_fetch_assoc($result)) {
                    $activity_id = $row['id'];
                    $activity_name = $row['name'];
                    $activity_description = $row['description'];
                    $activity_end_date = $row['endDate'];
                    $activity_start_date = $row['startDate'];
                    $activity_type = $row['type'];
                    $activityAuthor = $row['author'];
                    $activityPublished = $row['publishedAt'];
                    $activityLikes = $row['likes'];
                    $activityDislikes = $row['dislikes'];
                    $activityComments = $row['comments'];
                    $activityViews = $row['views'];

                    $query = "SELECT * FROM users WHERE Username = '$activityAuthor'";
                    $result = mysqli_query($link, $query);
                    if(!$result) {
                      die("MySQL Query Failed: " . mysqli_error($link));
                    }
                    $row = mysqli_fetch_assoc($result);
                    $authorID = $row['id'];
     }

     $output.="<div class='row'>
          <div class='col-md-6'>
            <a href='#'>
              <img class='img-fluid rounded mb-3 mb-md-0' src='img/<?php echo '$activity_type';?>.jpeg' alt=''>

          <div class='col-md-6'>
            <h3><?php echo $activity_name;?></h3>
            <p class='lead text-secondary'>Proposed by <a class='text-secondary lead' href='profile.php?id=<?php echo $authorID;?>'><?php echo $activityAuthor;?></a> at <?php echo $activityPublished;?></p>

            <p><?php echo $activity_description;?></p>
            <p><strong>Starts at:</strong> <?php echo $activity_start_date;?></p>

            <a class='btn btn-outline-success' href='config/like.php?page=<?php echo $page;?>&post=<?php echo $activity_id;?>'><i class='far fa-thumbs-up'></i> <?php echo $activityLikes;?></a>
            <a class='btn btn-outline-danger' href='config/dislike.php?page=<?php echo $page;?>&post=<?php echo $activity_id;?>'><i class='far fa-thumbs-down'></i>  <?php echo $activityDislikes;?></a>

            <div class='mt-3'><a class='btn btn-primary' href='activity.php?post=<?php echo $activity_id;?>&page=<?php echo $page;?>&commentpage=1'>View Activity</a></div>
          </div>
        </div>";

        }
        ?>
