推荐答案
看这段代码，我不确定您了解您想要获得什么以及PHP(或更确切地说是Web)如何工作.您的页面内容与PHP无关，直到您向服务器发送一些HTTP请求为止.您可以执行以下操作之一:1)将控件包装在<form>中，并使用"POST"方法提交整个表单；在服务器端处理POST数据，通过<name>属性值识别元素； 2)使用JavaScript读取某些控件的值，并使用AJAX将所需的HTTP请求立即发送到服务器.
两种方法都需要PHP API知识，第二种方法需要JavaScript.请参阅:
http://www.w3schools.com/php/php_post.asp [ http://en.wikipedia.org/wiki/Ajax_%28programming%29 [ ^ ]，
http://en.wikipedia.org/wiki/XMLHttpRequest [ http://www.w3schools.com/ajax/default.asp [ http://www.w3schools.com/php/php_ajax_php.asp [ http://www.w3schools.com/js/default.asp [
Looking at this code, I''m not sure you understand what do your want to obtain and how PHP (or rather Web) works. You page content has nothing to do with PHP until you send some HTTP request to the server. You can do one of the following: 1) wrap your control in<form>and submit a whole form with the method "POST"; process the POST data on the server side, recognize elements by their<name>attribute values; 2) use JavaScript to read the value of some controls and AJAX to send required HTTP request to the server immediately.
Both methods require knowledge of PHP API and the second one requires JavaScript. Please see:
