mysql_fetch_assoc() 期望参数 1 是资源，布尔值在第 9 行的 C:\xampp\htdocs\qcc\truckdelivery.php 中给出，没有选择数据库

我不知道我在哪里弄错了代码；此页面是我制作的充满车牌号的表格中的链接，我使用此代码将车牌号变成了链接。 

href="truckdelivery.php?id_truck=<?php echo $row_truck['id_truck']?>"><?php echo    $row_truck['truck_plate_no'];

在处理查询结果之前检查 MySQL 错误。您的查询很可能以某种方式出错，因此mysql_query()没有返回有效结果，因此mysql_fetch_assoc()失败。

// ...
$PK = mysql_query($sql_PK, $connect);
if ( mysql_error() ) {
  die ( mysql_error();
}
$row_PK = mysql_fetch_assoc($PK);
// ...

此外：mysql_x()函数已被弃用。请改用PDO或MySQLi。

您的connect.php文件可能缺少mysql_select_db()声明。检查那个。
