我想在 PHP 中创建高级搜索选项。我正在根据下拉框和单选按钮检索值。我想知道如何基于这些生成查询，例如如何首先从列表框和单选按钮中获取值。第二件事是我想知道如何在查询中包含多个变量，或者只是将查询完全留空。

例如：我应该按包含（R、Mahout、Storm、Python、Splunk）的组件类型过滤组件域（电信、公用事业、零售、BFSI、旅行、医疗保健）使用权（知识产权、无权）然后是杂项值比如按字母顺序排序，按版本等。

问题是可以从组件域和组件类型中选择多个值。或者它可以留空。我如何根据选择的内容进行搜索？如果有多个值，我如何相应地修改我的 php 查询？

我已经粘贴了下面的代码：你能像至少给我一个关于如何为组件类型生成查询并为其生成多个值的示例查询一样指导我吗

你应该把它放在某种查询中。我不知道你在用什么，但假设这是一个简单的 MySQL 语句，我会做这样的事情

$component_domain = isset($_GET['component_domain']) ? ' AND component_domain = '.$_GET['component_domain'] : '';
$component_type = isset($_GET['component_type']) ? ' AND component_type = '.$_GET['component_type'] : '';
$sort = isset($_GET['sort']) ? ' SORT BY '.$_GET['sort'].' '.$_GET['sort_direction'] : '';
$stmt = 'SELECT * FROM table WHERE something = "somevalue"'.$component_domain.$component_type.$sort;

然后运行您的查询。不是我最好的作品，但您可以根据需要对其进行修改。
