Filling A Form With Php And Passing Headers

Hi there, ihave a problem with a script that im working right now.
I have a form with some fields like this below:

<form name="formTradeLinks" method="post" action="index.php">
<input name="url" type="text" id="websiteurl" value="http://"
<input name="description" type="text" id="description" value="" size="30" maxlength="50">
<input type="submit" name="Submit" value="Submit Link">
</form>

I want to create a php script that fills this form (the fields url and description) and submits the form without entering the actuall page. Also i want the replay (to know if the forms submits ok) to appears in my script and not at the index.php. I know that i do this by passing headers but i havent done it before and i dont know how to do it.
A help is needed thanks for your consern!

 

Can you give a example? because i still don't get what you like to see!
