我需要修改一个php搜索脚本，以便它可以处理单个字段的多个条目。搜索引擎是专为房地产网站设计的。当前的搜索表单允许用户通过从下拉菜单中选择一个邻居来搜索房屋。我不想使用下拉菜单，而想使用复选框列表，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端的复选框，但PHP脚本仅在最后一个复选框中选择房屋。例如，如果我选择：'达拉斯''波士顿''纽约'，搜索引擎将只搜索纽约的房屋。修改PHP搜索脚本以处理单个输入的多个条目
进出口新的PHP，所以我有点手足无措，如何修改这个脚本来处理我所描述的行为：

哇......这是一个很大的代码，你贴，以及它的很多无关你的问题。是否有可能将其缩小到表单的html以及处理表单的脚本部分？另外我注意到wp_custom_fields_search（），这与wordpress有什么关系吗？如果是这样，也许你应该添加一个wordpress标签的问题。 – 2010-04-11 06:30:10
这就是问题所在，我不是一个PHP开发人员，所以我不确定这段代码的哪些部分与我需要修改的功能有关，以便按照我的需要进行修改。 – Thomas 2010-04-11 06:38:38
哦，是的，它是一个WordPress插件明确这一个： http://www.don-benjamin.co.uk/projects/foss/wp-plugins/wp-custom-fields-search-03/#post-41 我将添加标签.... – Thomas 2010-04-11 06:39:30
