Question

所以我正在创建一个注册表单，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代码，在Javascript.js中：

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，我需要再次使用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，所以我使用各种php函数？

Answer 1

继承人提示：提交后，该值可以存储为PHP中的$ _SESSION值。

Answer 2

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JavaScript中，在getTotal()函数内添加以下行（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！

您可以使用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']); ?>" />

Answer 3

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，然后在下一页上检索POST的值并将其传递到另一个隐藏字段中然后可以使用将值存储到数据库中。
