多选PHP

问题描述

<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
<select name="test[]" multiple="multiple">
    <option value="one">one</option>
    <option value="two">two</option>
    <option value="three">three</option>
    <option value="four">four</option>
    <option value="five">five</option>
</select>
<input type="submit" value="Send" />
</form>
<?php

    $test=$_POST['test'];
    if ($test){
     foreach ($test as $t){echo 'You selected ',$t,'<br />';}
    }
if($t=='one')
   $price1=12;
if($t=='two')
   $price2=2;
$total = $price1 + $price2;

echo $total;

当一个&都选择了两个，我希望结果为14.加法得到14个结果的最佳方法是什么?

When one & two are both selected i'd like the result to be 14. What is the best way to make an addition to obtain 14 as a result ?

推荐答案

必须将if $ t = one等放置在循环内

You must place the if $t = one , etc. inside the loop
