根据 SELECTvalue POST 到不同的页面？

我有一个表单，具体取决于我想要发送到不同页面的

我不知道执行此操作的最佳方法，但我认为最好的方法可能是有一个中间页面始终发布到，然后让中间页面检查从

谢谢！！

这是一个好办法。另一种方法是使用 Javascript 拦截点击，重写表单的 action 属性并 submit() 它。

对于您的 PHP：

首页：

<form action="intermediary.php" method="post">
  <input id="submitTo">
    <select value="1">goToFirstPage</select>
    <select value="2">goToSecondPage</select>
  </input>
</form>

第二页：

<?php
  $url = "";
  if($_POST["submitTo"] == "1") $url = "http://mysite.com/firstPage.php";

 if($_POST["submitTo"] == "2") $url = "http://mysite.com/secondPage.php";

 header ("Location: $url");    
?>




Don't put actual URLs in your first page, or you'll run into massive security issues.

THat's a good way. The alternative is to use Javascript to intercept the click, rewrite the action property of the form and submit() it.

For your PHP though:

First page:

<form action="intermediary.php" method="post">
  <input id="submitTo">
    <select value="1">goToFirstPage</select>
    <select value="2">goToSecondPage</select>
  </input>
</form>

Second page:

<?php
  $url = "";
  if($_POST["submitTo"] == "1") $url = "http://mysite.com/firstPage.php";

 if($_POST["submitTo"] == "2") $url = "http://mysite.com/secondPage.php";

 header ("Location: $url");    
?>



Don't put actual URLs in your first page, or you'll run into massive security issues.

这当然是用户兼容性的最佳方法。

您可以使用 HTTP 重定向标头来完成此操作，例如，

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

应在页面有任何输出之前调用该标头。

这样，当用户按下前进/后退按钮时，他甚至不会登陆到中间页面。

我看到的唯一其他选择是使用 javascript 来更改表单目标或这些行中的某些内容，但这有一些警告（必须启用 javascript，代码更复杂，重定向不应该真正发生在页面视图中）

that certainly would be the best method for user compatibility.

you could do it using the HTTP redirect header, e.g.

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

which should be called before there is any output to the page.

That way the user won't even land on the intermediate page when he presses the forward/back buttons.

the only other option I see would be to use javascript to change the form target or something salong those lines, but that has some caveats (javascript has to be enabled, more complicated code, redirection shouldn't really happen in the view of a page)

然后

function form_submitted(){
   switch(document.myform.select_name.value){
     case 'whatever':
        document.myform.target.value = "whatever_you_need";
        break;
     case 'whatever2':
        document.myform.target.value = "whatever_you_need_2";
        break;
    }
}

，要么将此函数分配给具有“onSubmit”属性的表单，要么使用一个调用该函数的按钮（而不是提交按钮）并在函数末尾添加 document.myform.submit() 。

javascript

function form_submitted(){
   switch(document.myform.select_name.value){
     case 'whatever':
        document.myform.target.value = "whatever_you_need";
        break;
     case 'whatever2':
        document.myform.target.value = "whatever_you_need_2";
        break;
    }
}

Then either assign this function to the form with the "onSubmit" attribute, or have a button (rather than submit button) that calls that function and add document.myform.submit() at the end of the function.
