Give your IFRAME a name, best the same as the ID (as old IE can't distinguish the two).

Then in your FORM:

<form target="name">

<form target="name">

where name is the name of the IFRAME.

- I have setup a form, named it "gateway.php", like this

<form action="get_gateway.php" action="post">

<form action="get_gateway.php" action="post"> <form target="ifrm"> Your affiliate ID: <input type="text" name="affID" /> <input type="submit" /> </form>

- Then, I setup another page, named "get_gateway.php", which should render an output like this:

<script language="JavaScript" src="http://mydomain/someJS.js"></script>

<script language="JavaScript">

<script language="JavaScript" src="http://mydomain/gateway.php?affID={HERE SHOULD BE THE AFFILIATE ID}"></script>

The problem is, that when submitting a form, it renders affID in url bar and redirects to "get_gateway.php" - but the iframe does not show? I used an iframe from previous post, rename its name & id and put the textarea in it, but no luck. This iframe is giving me a headache
Pls, help!

You should just add the "name" attribute to the original form.

eg:

<form action="get_gateway.php"  target="ifrm" method="post"> 
Your affiliate ID: <input type="text" name="affID" />
<input type="submit" />
</form>

<form action="get_gateway.php" target="ifrm" method="post"> Your affiliate ID: <input type="text" name="affID" /> <input type="submit" /> </form>

Note that the action="post" should be method="post". The action attribute denotes the url that you want the form to pass its name/value pairs to.

Your IFRAME should be named ifrm.

For your gateway.php file:

<script language="JavaScript" src="http://mydomain/someJS.js"></script>

<script language="JavaScript">
</script>
<script language="JavaScript" src="http://mydomain/gateway.php?affID=<?php echo urlencode($_POST['affID']); ?>"></script>

<script language="JavaScript" src="http://mydomain/someJS.js"></script> <script language="JavaScript" src="http://mydomain/some_moreJS.js"></script> <link type="text/css" rel="stylesheet" href="http://mydomain/some.css"> <script language="JavaScript"> </script> <script language="JavaScript" src="http://mydomain/gateway.php?affID=<?php echo urlencode($_POST['affID']); ?>"></script>

The PHP code:

Help with Code Tags

php Syntax (Toggle Plain Text)

<?php echo urlencode($_POST['affID']); ?>

<?php echo urlencode($_POST['affID']); ?>

will write the affID value so that the JavaScript file will know what it is.

The urlencode() serves to encode the affID value for URL transmission as well as prevent XSS injection into your page.

The problem is that iframe does not show up?
What am I doing wrong?
Thx,
