我试图让我的复选框在页面底部输出“Korting is ... %”，具体取决于选中哪个复选框，例如选中第 2 个和第 3 个框会输出“Korting is 15%”但我不能似乎让它工作。有人可以帮我提前谢谢你

You need to use a name ending in [] such as name="korting[]". Then you can use $_POST['korting'] which will be an array containig the values of the checked checkboxes.

Note that $_POST['korting'] will not be set at all if no checkbox is checked!

  • 如果您想选择一个选项，请使用radio而不是checkbox
  • 不要使用 PHP_SELF，这是一个安全漏洞。反而：<form action="">
  • 访问值$_POST['korting']

总结所有值，使您的表单如下所示：

<input type="checkbox" name="korting[]" value="15" /> Student 15% <br/>
<input type="checkbox" name="korting[]" value= "10"  /> Senior 10% <br/>
<input type="checkbox" name="korting[]" value= "5" /> klant 5% <br/>

和这样的处理：

<?php
$korting = 0;
if (isset($_POST['korting']) && is_array($_POST['korting'])) {
  $korting = array_sum($_POST['korting']);
}
echo 'Korting is ' . $korting . '%';
?>
