PHP中的高级搜索选项

Question

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，例如首先如何从列表框和单选按钮获取值。 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空白。

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）使用权限（知识产权，无权限）然后是其他值例如按字母顺序，版本等排序。

问题是可以从组件域和组件类型中选择多个值。 或者可以将其留空。 如何根据所选内容进行搜索？ 并且如果有多个值，我如何相应地修改我对php的查询？

我粘贴了以下代码：您能像至少给我一个指导吗，给我一个示例查询，说明如何生成组件类型的查询并为其生成多个值

Answer 1

您应该通过某种查询将其放在一起。 我不知道您在使用什么，但是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;

然后运行查询。 不是我的最佳作品，但是您可以根据需要进行修改。
