'Submit form, don't show param and value in URL? [duplicate]

I have a simple form and when the select field is changed it submits the form reloading the current page passing the select value to the page.

<form>
  <select id='query' name='query' onchange='this.form.submit()'>
    <option value=1>1<option>
    <option value=2>2<option>
  </select>
</form>

This works fine, but the URL then contains pagename.php?query=2 Is there anyway to do this without the parameter and value being seen in the URL ?

Thanks

When you use form, it has a paramatter that if you dont put nothing, it is METHOD="GET", this makes the petition and sends data from URL, so you should put METHOD="POST":

<form method="post">
  <select id='query' name='query' onchange='this.form.submit()'>
    <option value=1>1<option>
    <option value=2>2<option>
  </select>
</form>

You will have to make some more changes in your php, but i don't have enought information about it to help you.
