POST <form>中的GET参数

Question

is it possible to put some post input values to a 'action' url?

For example:

<form method="post" action="index.php">
<input type="text" name="username">
<input type="submit">
</form>

The resulting URL is index.php but I want to add name's value at the end of url like this:

index.php?name=value

I don't want to change from 'post' to 'get'.

If you want to post form, do as you did already. You can also add GET parameters in action, like:

<form method="post" action="index.php?name=value">
  <input type="text" name="username">
  <input type="submit">
</form>

It is also possible to dynamically change action before posting.

You can achieve it with something like that:

<script type="text/javascript">
function changeAction() {
  this.action += '&other=value';
}
</script>

<form method="post" action="index.php?name=value" onsubmit="changeAction()">
  <input type="text" name="username">
  <input type="submit">
</form>
