我有一张表格，代码如下，
这个表格里有select和checkbox，我试图用表单包装我的表格并将其提交到results.php来输出，
但是当我提交表单时，它没有起作用。如何从results.php获取复选框的选中值？
<script>
var currentSelected = "";
var currentItem = "";
function show(obj, item) {
if (currentSelected != "" && currentSelected != obj) {
currentSelected.checked = false;
document.getElementById(currentItem).style.display = currentSelected.checked ? "block" : "none";
}
document.getElementById(item).style.display = obj.checked ? "block" :"none";
currentSelected = obj;
currentItem = item;
}
</script>

<?php
//how to echo the checkbox value ?????????
$quickselect= $_POST["quickselect"];
$locselect =$_POST["locselect "];
$keyword = $_POST["keyword "];
?>
var_dump()或者print_r()的函数来输出$_POST变量的值，并告诉我们你看到了什么。例如：<?php var_dump($_POST); ?>- Muriano
