Javascript PHP脚本，可以在提交时使用if和else语句使用默认值计算表单值。到page2.php

更新j_s_stack我在这里添加了大部分代码，让您可以看到脚本所做的计算，正如您在评论选项卡中所知道的，我对php脚本和论坛脚本做了一些更改，相应地更改了id

您的条件调查报价为：
我会把所有的计算都放在一个函数中。然后设置另一个IF条件以查看用户选择了什么：

<?php 

    function calulate(){
        $calc = $_POST['fldAgeOfProp'] + $_POST['fldAPV']; //... 
        Switch ($_POST['fldPropertyType']){                 
                    case 'Semi': 
                       $calc  = $calc + 60;
                    case 'Terraced': 
                       $calc  = $calc + 40;
                    //... For all cases
        }
        return $calc;
    }

    If(isset($_POST['submit'])){
        if($_POST['fldST'] == 'not-sure'){

我没有再次测试过它，所以它们可能有一些错误。
你能简单地告诉我你的需要吗，伙计。我真的不明白你的需要。@Outlooker有点复杂：这是第一个问题：为了解决问题，我让Jrad51提出了一个新问题，我看不到addtwo函数的意义！这个函数只是对两个变量进行简单的加法。对不起，我仍然在努力学习，有时候说太多会让人困惑，我想这并不是简单的，问题是我还不知道该要求什么来保持它的简单，因为我还在学习代码和短语：p让你有时间看看代码，了解我做了什么。顺便说一下：我的名字
是j_s_stack
，有个错误，应该是
calculate（）
不需要。我在这里这么做，因为一开始我也需要很多帮助，现在我只想尽可能多的回馈…这对它没有影响，因为计算现在已经在运行中了。问题是拼写错误。变量名为
$quote
，但在
回送中，我编写了
$quote
。您需要更改我添加的条件quote的附加值
