Answer 1

您的按钮名称属性未正确设置

<button type="submit" name
            "add">ADD</button></td>

像这样：

<button type="submit" name="add">ADD</button></td>

此外，表单元素周围没有表单标记：

<form action="" method="post">       //set action to the PHP file
//your table goes here

</form>

除此之外，请确保您的名称属性与post数组键相同..例如：

$username = ($_POST['username']);

无法获得以下内容的价值：

<input type="text" name="usernamr" placeholder="stud name" required/>

因为name username = usernamr ..

if（isset（$ _ POST ['add']））不起作用？
