[英]How to deal with two submit buttons in a form?
I don't understand this, 我不明白这个,
if I do this and I click the check out button , the page won't go to the check out page , 如果我这样做,我点击结账按钮 ,页面将不会进入结账页面 ,
<form action="cart.php" method="post" id="form-cart">
<button name="update" id="update" type="submit" value="Update cart">Update cart</button>
<button name="checkout" id="checkout" type="submit" value="Check out">Check out</button>
</form>
It only does if I change the name="checkout"
to name="cart-checkout"
, 只有当我将
name="checkout"
更改为name="cart-checkout"
时才name="cart-checkout"
,
<form action="cart.php" method="post" id="form-cart">
<button name="update" id="update" type="submit" value="Update cart">Update cart</button>
<button name="cart-checkout" id="checkout" type="submit" value="Check out">Check out</button>
</form>
It works that way but does not make any sense to me, do you know why it does it that way? 它是这样工作但对我没有任何意义,你知道它为什么这样做吗?
So I tried to use <a>
tag inside the <button>
tag and it goes to the check out page, 所以我尝试在
<button>
标签内使用<a>
标签,然后进入结账页面,
<form action="cart.php" method="post" id="form-cart">
<button name="update" id="update" type="submit" value="Update cart">Update cart</button>
<button name="checkout" id="checkout" type="submit" value="Check out"><a href="checkout.php">Check out</a></button>
</form>
But does it a valid html to put <a>
tag inside the <button>
tag? 但是将
<a>
标签放在<button>
标签内是否有效 ?
Why not change the buttons to: 为什么不将按钮更改为:
<input name="update" id="update" type="submit" value="Update cart">
<input name="cart-checkout" id="checkout" type="submit" value="Check out">
Then in PHP (on cart.php) you can do: 然后在PHP(在cart.php上)你可以做:
<?php
if($_POST){
if(isset($_POST['update']){
// process update
} else if(isset($_POST['cart-checkout']){
// process cart checkout
// or uncomment the below line to forward to checkout.php
// header("Location: checkout.php");
}
}
?>
What about making one <button>
that simply acts like a <a href="">
? 如何制作一个像
<a href="">
<button>
一样的<button>
呢?

Whoops, sorry, misread. 哎呀,抱歉,误读。
<button onclick="window.location='/nextpage';">
? <button onclick="window.location='/nextpage';">
?
我实际上会在这里使用带有onclick
事件的JavaScript,它会带你到结帐页面。
