Question

我似乎无法找出为什么我的PHP不会与我的HTML链接。想法是根据调查弹出某些图片。例如，如果数字加起来超过50，将弹出“bromley.jpg”。虽然只是说“宿舍”而不是图片，但这种情况并没有发生。

Answer 1

您的基本问题是您希望值是选择下拉列表中所有值的总和。表单提交不起作用。您需要单独获取每个选定选项的值，然后将其添加。像这样：

$value = 0;
$value += $_GET["Quad"];
$value += $_GET["Lion"];
$value += $_GET["Gym"];
$value += $_GET["Meal"];
$value += $_GET["Private"];

这将在图像标记之前，并将选择“Quad”选择的值并将其添加到总计。那么它将取“狮子”选择的价值等等。

这不是很好，但它应该让你朝着正确的方向前进，并让你了解表格的提交方式。

Answer 2

看起来你没有用实际值填充$ value。

在$ dorm = dorm：

之前加上以下内容

$ value = $ _GET [“value”]

假设您正在调用结果脚本，例如results.php？value = 50

PHP图像链接到HTML
