Taking a text field and moving info to the next page

Ok, one my main page I want to have a text box that says "Enter Desired User name here" or something, then when you submit, it brings you to signup.php and the text box for user is already filled in, any ideas on how to do this?

 

try this

in your mainpage

<form method="post" action="signup.php">
<input type="text" name ="username" size= 14>
<input type ="submit" name = "submit" value ="submit">
</form>

then on your submit.php include the following code

Hope it helps
