PHP提交按钮不起作用。

Question

<?php
if(isset($_POST['submit'])){
header('Location: http://www.rate.ee');
}
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

    <head>

        </title>
    </head>
    <body>
        <input type="submit" name="submit" id="submit" class="button" value="Submit"/>
    </body>
</html>

This is my code. 这是我的代码。 Very simple, isn't it. 很简单，不是吗。 But it doesn't work and I don't get it.. I always thought that PHP only executes when I load the page, but the other page where I use same code works very well without JS.. 但它不起作用，我不明白..我一直认为PHP只在我加载页面时执行，但是我使用相同代码的另一个页面在没有JS的情况下工作得非常好。

Answer 1

You need to wrap your button in a <form> tag: 您需要将按钮包装在<form>标记中：

<form action="" method="post">
<input type="submit" name="submit" id="submit" class="button" value="Submit"/>
</form>

Answer 2

You need a form surrounding the input. 您需要一个围绕输入的表单。

<body>
<form action="welcome.php" method="post">
  <input type="submit" name="submit" id="submit" class="button" value="Submit"/>
</form>
</body>
</html>

Answer 3

You have no form tag and even if you did it would need the method="post" attribute. 您没有表单标记，即使您这样做，也需要method =“post”属性。

<form method="post" action="<?php echo $_SERVER[PHP_SELF]?>">
    <input type="submit" name="submit" id="submit" class="button" value="Submit"/>
</form>
