编码/形成问题 [英] Coding/form problem

问题描述

嗨。

我刚刚学习Php的初期阶段，只需要一个

的小帮助。


我有一个包含价值观的表格。但是，当我测试它时，

值不会被累加并传送到结果页面。我只是

想知道你是否能发现它有什么不对吗？

这是页面上的表格tourprice.php：


< form name =" frm_tourprice" ID = QUOT; frm_tourprice" method =" post"

action =" tourprice_processor.php">

< table width =" 60％"边界=" 0" CELLSPACING = QUOT; 0" cellpadding =" 3">

< tr>

< td>成人人数< / td>

< td>< input name =" numAdults"类型= QUOT;文本" id =" numAdults"

/>< / td>

< / tr>

< tr>

< td>子女数< / td>

< td>< input name =" numChildren"类型= QUOT;文本" id =" numChildren"

/>< / td>

< / tr>

< tr>

< td>旅游名称< / td>

< td>< select name =" tourName" id =" tourName">

< option value =" 500">阿根廷的亮点< /选项>

< option value =" 700" ;>加拿大西部的亮点< /选项>

< option value =" 900">埃及金字塔和更多< / option>

< / select> ;< / td>

< / tr>

< tr>

< td>& nbsp;< / td>

< td>< input type =" submit"命名= [提交" value =" Submit"

/>< / td>

< / tr>

< / table>

< / form>


在tourprice_calculator.php页面上，它应该根据您选择的内容添加所有内容

up给你正确的费用。我保持

虽然返回零。


这是在tourprice_calculator.php的顶部


< ;？php

$ numAdult = $ _POST [''numAdults''];

$ numChild = $ _POST [''numChildren''];

$ basePrice = $ _POST [''tourName''];

$ tourPrice =（numAdult * basePrice）+（numChild * basePrice）

？>


继续在页面上我有以下内容：


旅游价格计算器< / h1>

< ; p>您的旅行的估计费用是< strong><？php echo

$ tourPrice; ？>< / strong>。< / p>

< p>价格包括酒店，住宿和旅行费用

。它们不包括到起始目的地的机票。< / p>

< p>< a href =" tourprice.php"> Calculate< / a>另一个旅游。< / p>

< p>< a href =" contact.php">联系< / a>我们的合格

代理商之一。< / p>

非常感谢您的帮助。我对这个有点困惑。我认为它可能是一些字符串，如$ Adult $ Adults $ Children

$ Child等错误，但当我尝试更改它时仍然

为零。

Hi.
I am just in the very early stages of learning Php and just need a
little help.

I have a form which includes values. However when I test it, the
values are not added up and carried to the results page. I just
wondered if you can spot whats wrong with it?
This is the form on the page tourprice.php:

<form name="frm_tourprice" id="frm_tourprice" method="post"
action="tourprice_processor.php">
<table width="60%" border="0" cellspacing="0" cellpadding="3">
<tr>
<td>Number of Adults </td>
<td><input name="numAdults" type="text" id="numAdults"
/></td>
</tr>
<tr>
<td>Number of Children </td>
<td><input name="numChildren" type="text" id="numChildren"
/></td>
</tr>
<tr>
<td>Tour Name </td>
<td><select name="tourName" id="tourName">
<option value="500">Highlights of Argentina</option>
<option value="700">Highlights of Western Canada</option>
<option value="900">Egyptian Pyramids and More</option>
</select></td>
</tr>
<tr>
<td>&nbsp;</td>
<td><input type="submit" name="Submit" value="Submit"
/></td>
</tr>
</table>
</form>

On the tourprice_calculator.php page it is supposed to add everything
up depending on what you select and give you the correct cost. I keep
getting a zero returned though.

This is at the top of tourprice_calculator.php

<?php
$numAdult = $_POST[''numAdults''];
$numChild = $_POST[''numChildren''];
$basePrice = $_POST[''tourName''];
$tourPrice = (numAdult * basePrice) + (numChild * basePrice)
?>

Further down on the page I have the following:

Tour Price Calculator </h1>
<p>The estimated cost of your tour is <strong><?php echo
$tourPrice; ?></strong>.</p>
<p>Price includes hotel, accommodation, and travel expenses during
the tour. They do not include airfare to the starting destination.</p>
<p><a href="tourprice.php">Calculate</a> another tour.</p>
<p><a href="contact.php">Contact</a> one of our qualified
agents.</p>
Thanks very much for any help. Im a little confused with this one. I
thought it might be some of the strings like $Adult $Adults $Children
$Child etc that were wrong, but when I tried changing those it still
comes up as zero.
