我需要修改php搜索脚本，以便它可以处理单个字段的多个条目。搜索引擎是为房地产网站设计的。当前搜索表单允许用户通过从下拉菜单中选择单个邻域来搜索房屋。我想使用复选框列表而不是下拉菜单，以便用户可以一次搜索多个社区中的房屋。我已将所有下拉菜单项转换为HTML侧的复选框，但PHP脚本仅搜索所选最后一个复选框中的房屋。例如，如果我选择：'达拉斯''波士顿''纽约'，搜索引擎将仅搜索纽约的房屋。
我是PHP的新手，所以我对如何修改此脚本以处理我所描述的行为感到有点不知所措：

您的需求需要使用新的输入类对插件进行非平凡的扩展。您可能应该联系插件的开发人员来请求该功能或搜索满足您需求的另一个插件。
如果你真的想自己解决这个问题，我建议把插件放在一边，滚动你自己的搜索表单并将输入推送到WP_query()。这里有一些链接可以帮助您开始：
