在第二行中的require_once（）之后缺少。不知道为什么在第5行说错误，也许你清除了一些评论？
答案 1 :(得分：0)
我在你发布的代码片段中看到很多问题，但是唯一想到的可能是第5行的问题是$ _POST ['course_name']没有设置。
但是，如果不知道发布值的形式是什么样的话，就不可能说了。

最后一个是我第一篇文章中的那个。
答案 3 :(得分：0)
我非常确定form标签必须在body标签之后，但那是次要问题。你的第二组代码在每个post变量的末尾添加一个数字，但你的最后一段代码似乎并没有反映出这一点。
不要在每个表单变量的末尾使用数字，而是使用数组，就像这样
<input type='text' name='nric[]'>
它将成为您可以通过
访问的$nric = $_POST["nric"];
echo "<pre>".print_r($nric, true)."</pre>";
