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

</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 $2/hr.</i><br /><br />
Total Price:<div class="inline totalPrice"> </div>
<br/>
<input type="submit" name="formSubmit" value="Submit" class="button greenButton"/>
<input type="button" name="cancel" value="Cancel" class="button redButton" onclick="href='activemindandbody.org'">
</form>
</body>
</html>
以下是javascript.js:中的javascript代码
function weekPrice()
{
var weekPrice=0;
var theForm = document.forms["paymentform"];
var includeWeek1 = theForm.elements["includeweek1"];
var includeWeek2 = theForm.elements["includeweek2"];
var includeWeek3 = theForm.elements["includeweek3"];
var includeWeek4 = theForm.elements["includeweek4"];
var includeWeek5 = theForm.elements["includeweek5"];
var includeWeek6 = theForm.elements["includeweek6"];
var afterCampCare = theForm.elements["aftercampcare"];
if(includeWeek1.checked==true)
{
weekPrice= weekPrice + 75;
}
if (includeWeek2.checked==true)
{
weekPrice= weekPrice + 75;
}
if (includeWeek3.checked==true)
{
weekPrice= weekPrice + 75;
}
if (includeWeek4.checked==true)
{
weekPrice= weekPrice + 75;
}
if (includeWeek5.checked==true)
{
weekPrice= weekPrice + 60;
}
if (includeWeek6.checked==true)
{
weekPrice= weekPrice + 75;
}
if (afterCampCare.checked==true)
{
weekPrice= weekPrice + 2;
}
return weekPrice;
}
function getTotal()
{
var weekTotalPrice = weekPrice();
document.getElementsByClassName("totalPrice")[0].innerHTML = "" + weekTotalPrice;
}
这是我的问题：在下一页，我需要再次获得totalPrice的值，并需要在html上输出它。在那之后的页面上，我需要将相同的值存储到数据库中。那么，如何使用php存储Javascript函数值，从而使用各种php函数呢
这里有一个提示：提交后，该值可以作为$_SESSION值存储在PHP中。
在HTML页面上，在<form>和</form>标记之间添加以下内容：
<input type="hidden" name="totalprice" />
在您的JavaScript中，在getTotal()函数中，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，此字段也将被发送过来！
您可以使用PHP在下一页访问它，方法是：
<?php echo($_POST['totalprice']); ?>
您可以通过以下操作将其添加到另一个隐藏字段：
<input type="hidden" name="totalprice" value="<?php echo($_POST['totalprice']); ?>" />
为什么不在第一页表单上使用JavaScript函数将总值设置为隐藏输入字段值，然后在下一页检索POST'ed值并将其传递到另一个隐藏字段中，然后可以使用该字段将值存储到数据库中。
