我有一个带有“订阅”按钮和“取消订阅”按钮的表单。我想根据点击的按钮，提交订阅或取消订阅的值。
如果单击“订阅”或“取消订阅”，我已经将根据应该发生的事情放在一起。现在我只需确定点击了哪个按钮。
这是我的HTML：
<form action="../external/multisubscribe.php" method="post" width="600px" style="margin: 0 auto;">

答案 0 :(得分：0)
我在您的html中进行了一些更改，例如向name添加form（我为了澄清目的而删除了一些内联css），例如：< / p>
<form action="../external/multisubscribe.php" method="post" name="theForm">
同样在submit个输入中，我添加了id并更改了names，例如：
<button type="submit" name="subscribe" id="subscribe" class="button">Subscribe</button>
<button type="submit" name="unsubscribe" id="unsubscribe"title="Unsubscribe">Unsubscribe
</button>
我还更改hidden输入，添加id，例如：
<input name="action" id="action" value="subscribe" type="hidden" />
现在，使用javascript代码（可以改进，我知道）：
document.getElementById('subscribe').addEventListener('click',function(e){
e.preventDefault();
document.getElementById('action').value = 'subscribe';
document.theForm.submit();
})
document.getElementById('unsubscribe').addEventListener('click',function(e){
e.preventDefault();
document.getElementById('action').value = 'unsubscribe';
document.theForm.submit();
})
这样我们就会将行动（
subscribe或unsubscribe）存储到hidden输入中。
然后在您的php代码中，检查您的action值：
$theAction = $_POST['action'];
if($theAction === "subscribe"){
//subscribe code
}
else{
//unsubscribe code
}
