说实话，我对PHP一无所知，但我可以看到它的强大，我只是想学习如何控制它。我有一个三页的预订表格。第一到第二页可以正常工作，但第二到第三页不能正常工作。这是第二页的 PHP 代码 -

<?php

// Total Number of Nights Between Picked Dates

$days = (strtotime($_POST["checkoutdate"]) - strtotime($_POST["checkindate"])) / 86400 - 1;

// Extra Nightly Cost

define ("extranights", 80);
$addnights = (int)extranights * ($days - 4);

// Deposit Price Calculation

define("deposit", 370); 
$deposit = null;

if (isset($_POST["numberofpeople"])) {
$numberofpeople = intval($_POST["numberofpeople"]);
$deposit = ((int)deposit * $numberofpeople + $addnights) * 0.3;
}     

// Total Price Calculation

define("totalprice", 370);  
$result = null;

if (isset($_POST["numberofpeople"])) {
$numberofpeople = intval($_POST["numberofpeople"]);
$result = (int)totalprice * $numberofpeople + $addnights;
}     

?>

然后我在同一页面上呼应了 deposit 和 totalprice 的值

<table>
<tr>
                <td width="573" height="30" align="right" valign="bottom" style="color:#0099FF;">( confirm reservation ) 30% Deposit :</td>
                <td width="158" align="left" valign="bottom" style="color:#0099FF; font-size:1.8em; line-height:23px;">&#8364;<?php echo $deposit; ?></td>
              </tr>

              <tr>
                <td height="30" align="right" valign="bottom" style="color:#0099FF;">Total Price :</td>
                <td align="left" valign="bottom" style="color:#0099FF; font-size:1.8em; line-height:23px;">&#8364;<?php echo $result; ?></td>
              </tr>
<td width="131" align="right" valign="middle" style="color:#000;"><input type="submit" name="submit" id="formbtn" value="CONTINUE" /></td>
</table>

我一直在苦恼的是如何将存款和总价的回声值发布到第三页上。如果解决方案/答案很广泛，那么我将不得不回到绘图板并一点一点地重新开始。但这将完成表单的用户端。我不期待数据库的东西:(

或使用预期的：

<input type="hidden" name="deposit" value="$deposit" />

include some hidden fields on page 2 with the computed values.

....
<input type="text" name="deposit" value="$deposit" style="display:none" />
...
<input type="text" name="result" value="$result" style="display:none" />

the values will then appear on the 3rd page in the $_POST array

这个例子结合了 php、js(AJAX) 进行动态表单处理和通过获取所有参数发送，也许它可以节省你一些时间。不过，您应该根据需要更改它。

<table ALIGN="CENTER">
