Question

我想从类别字段中的数据库中获取记录，旁边有一个按钮，当我点击该按钮时会出现一个引导崩溃，我必须在其中显示来自另一个数据库的记录。特定的类别字段，它应该按照上面的类别字段动态获取记录，并且从管理端进行更改时将继续更改。我想在SQL查询中编写PHP代码，下面的代码显示没有错误，但没有为我提供预期的结果。请帮帮我朋友。

<?php

$conn = mysqli_connect("localhost","root","","zuuvee");
$query = mysqli_query($conn, "SELECT * FROM category_name");
$query1 = mysqli_query($conn, "SELECT * FROM subcategory_name WHERE category = 'Apparel & Accessories'");


?>
