因此，我正在创建一个注册表单，它根据用户的选择使用 javascript 计算 totalPrice，并返回该值并将其存储为一个类（称为 totalPrice）。

<body>
   <form id="paymentform" action="Session5.php" method="post">
   <label><b>Camp Sessions: 1-6 (Check off the week(s) the camper will be participating in.)</b> </label><br /><br />
   <ol>
   <li>July 8 - July 12 ($75/child)<input type=checkbox name="campsessions[]" value="July8-July12" onclick="getTotal()" id="includeweek1"></li>
   <li>July 15 - July 19 ($75/child)<input type=checkbox name="campsessions[]" value="July15-July19" onclick="getTotal()" id="includeweek2"></li>
   <li>July 22 - July 26 ($75/child)<input type=checkbox name="campsessions[]" value="July22-July26" onclick="getTotal()" id="includeweek3"></li>
   <li>July 29 - August 2 ($75/child)<input type=checkbox name="campsessions[]" value="July29-August2" onclick="getTotal()" id="includeweek4"></li>
   <li>August 6 - August 9 ($60/child)<input type=checkbox name="campsessions[]" value="August6-August9" onclick="getTotal()" id="includeweek5"></li>
  <li>August 12 - August 16 ($75/child)<input type=checkbox name="campsessions[]" value="August12-August16" onclick="getTotal()" id="includeweek6"></li>
   </ol>

   <label> <b> Include After Camp Care? </b></label> <input type="checkbox" name= "campcare" onclick="getTotal()" id="aftercampcare" /> <br /><br />
   <i> After Camp Care is available from 4pm-6pm for an additional charge of $2/hr.</i><br /><br />

      Total Price:<div class="inline totalPrice"> </div>
      <br/>



<input type="submit" name="formSubmit" value="Submit" class="button greenButton"/>
<input type="button" name="cancel" value="Cancel" class="button redButton" onclick="href='activemindandbody.org'">
</form>
</body>
</html>

这是 Javascript.js 中的 javascript 代码：

function weekPrice()
{
    var weekPrice=0;
    var theForm = document.forms["paymentform"];
    var includeWeek1 = theForm.elements["includeweek1"];
    var includeWeek2 = theForm.elements["includeweek2"];
    var includeWeek3 = theForm.elements["includeweek3"];
    var includeWeek4 = theForm.elements["includeweek4"];
    var includeWeek5 = theForm.elements["includeweek5"];
    var includeWeek6 = theForm.elements["includeweek6"];
    var afterCampCare = theForm.elements["aftercampcare"];


    if(includeWeek1.checked==true)
    {
        weekPrice= weekPrice + 75;
    }
    if (includeWeek2.checked==true)
    {
        weekPrice= weekPrice + 75;
    }
    if (includeWeek3.checked==true)
    {
        weekPrice= weekPrice + 75;
    }
    if (includeWeek4.checked==true)
    {
        weekPrice= weekPrice + 75;
    }
    if (includeWeek5.checked==true)
    {
        weekPrice= weekPrice + 60;
    }
    if (includeWeek6.checked==true)
    {
        weekPrice= weekPrice + 75;
    }
    if (afterCampCare.checked==true)
    {
        weekPrice= weekPrice + 2;
    }
    return weekPrice;
}
function getTotal()
{
var weekTotalPrice = weekPrice(); 
document.getElementsByClassName("totalPrice")[0].innerHTML = "" + weekTotalPrice;
}

这是我的问题：在下一页上，我再次需要 totalPrice 的值，并且需要将其输出到 html 上。在那之后的页面上，我需要将相同的值存储到数据库中。那么，如何使用 php 存储 Javascript 函数值，从而使用各种 php 函数呢？

这里有提示：一旦提交，该值可以存储为 PHP 中的 $_SESSION 值。

在 HTML 页面上，在<form>and</form>标记之间添加以下内容：

<input type="hidden" name="totalprice" />

在您的 JavaScript 中，在getTotal()函数内部，添加以下行（在设置 weekTotalPrice 之后）：

document.querySelector('input[type=hidden][name=totalprice]').value = weekTotalPrice;

然后，当您提交表单时，该字段也会发送过来！

您可以通过执行以下操作使用 PHP 在下一页上访问它：

<?php echo($_POST['totalprice']); ?>

您可以通过执行以下操作将其添加到另一个隐藏字段：

<input type="hidden" name="totalprice" value="<?php echo($_POST['totalprice']); ?>" />

为什么不直接使用 JavaScript 函数将总值设置为第一页表单上的隐藏输入字段值，然后在下一页检索 POST 的值并将其传递到另一个隐藏字段，然后您可以使用将值存储到数据库中。
