Sending data through post method to an iframe

Question

I have an iframe which is pointing to a moodle site. I need to pass to it my username and password, so that when the iframe is loaded, I am automatically logged in on moodle. So I have something like this:

<div id="iframe" style="width:787px; height:700px;">
<iframe id="iframeCon" src ="http://www.somesite.net/moodle/login/index.php" width="100%" height="100%" frameborder="0">

</iframe>

My question is how to send my username and password using POST method to this URL?

Answer 1

To POST to an iframe you must use form target.

<form
      id="moodleform" target="iframe"
      method="post" action="http://www.example.com/login/index.php"
>
    <input type="hidden" name="username" value="guest"/>
    <input type="hidden" name="password" value="guest"/>
    <input type="hidden" name="testcookies" value="1"/>
</form>
<iframe name="iframe"></iframe>
<script type="text/javascript">
    document.getElementById('moodleform').submit();
</script>
