警告：mysqli_fetch_assoc（）期望参数1是mysqli_result，boolean任何解决方案？

Question

这是我的代码，当我执行查询时出现此错误。

<?php
      $featured_status = $_GET['eFeaturedStatus'];
    $query = "SELECT * FROM Event WHERE eFeaturedStatus = $featured_status ";
    if (!$query) {
    echo 'MySQL Error: ' . mysqli_error();
    exit;
}
    $select_all_events_query = mysqli_query($connection,$query);
    while ($row = mysqli_fetch_assoc($select_all_events_query)){
      $event_name = $row['eName'];
  ?>
