我有一张表，代码如下， 该表有select和checkbox，我尝试将表包装在一个表单中并发布到results.php以回显， 但是在提交表格时，它不起作用。如何从results.php获取复选框选中的值？
<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>

要使用PHP从POST请求中检索值，您可以使用类似这样的内容
$checkbox = $_POST['absolute'];
参数名称和值与html标签上的相同。
例如：
<input name="absolute" type="checkbox" value="Your value" />

表示复选框：
$checkbox1=$_POST['absolute'];
$checkbox2=$_POST['quick'];
获取日期值
$from=$_POST['from'];
$to=$_POST['to'];
