我有一个可以触发贝宝或其他链接的表单。

如何通过PHP触发这些操作？

HTML:

<form action="myphp.php" method="POST />
  <input type="submit" value="paypal" name="action1" />
  <input type="submit" value="other" name="action2">
</form>

myphp.php：

if($_POST["action1"]) {
//https://www.paypal.com/cgi-bin/webscr should trigger here
}
if($_POST["action2"]) {
//https://www.someotherwebsite.com/pay should trigger here
}

使用：

if($_POST["action1"]) {
header('Location: https://www.paypal.com/cgi-bin/webscr');
exit;//it's a good habit to call exit after header function because script don't stop executing after redirection
}

只需使用header:

header('Location: http://www.example.com/');

在php中，可以使用header()方法：

if($_POST["action1"]) {
   header('Location: https://www.paypal.com/cgi-bin/webscr');
}
if($_POST["action2"]) {
   header('Location: https://www.someotherwebsite.com/pay');
}

使用隐藏输入。

<form action="myphp.php" name="form1" method="POST" />
   <input type="hidden" name="action" />
   <input onclick="setHidden(this)" type="button" value="paypal" />
   <input onclick="setHidden(this)" type="button" value="other" />
</form>
<script>
    function setHidden(element) {
       document.form1.action.value = element.value;
       document.form1.submit();
    }
 </script>

然后在PHP 中

if($_POST["action"] == "paypal") {
    header('Location: https://www.paypal.com/cgi-bin/webscr');
}
else if($_POST["action"] == "other") {
    header('Location: https://www.someotherwebsite.com/pay');
}

只需检查是否存在isset:

if(isset($_POST["action1"])) {
//https://www.paypal.com/cgi-bin/webscr should trigger here
}
if(isset($_POST["action2"])) {
//https://www.someotherwebsite.com/pay should trigger here
}
