Ok, I am doing a sort of a project right now... It is like a php chat room that records every message into a database. Now, on the first post I want it to like set the name, so on first post it would say Name: and you set your name, then on every other message you post it just says Posted by and remembers your name from the last entry. Is this anyhow possible?

Check session... if no name, display name prompt, otherwise don't display name prompt. Cheers, Rob.

which would I choose. http://us2.php.net/manual-lookup.php?pattern=sessions

In brief: if( isset( $_POST['userName'] ) && !empty( trim( $_POST['userName'] ) ) ) {

    //
    // Save userName to session.
    //
    $_SESSION['userName'] = trim( $_POST['userName'] );

} if( isset( $_POST['message'] ) && !empty( trim( $_POST['message'] ) )

    &&
    isset( $_SESSION['userName'] ) )

{

    //
    // Handle submission of message.
    //

} if( !isset( $_SESSION['userName'] ) ) {

    //
    // Display user name prompt.
    //

} If I do that then i get this error

Fatal error: Can't use function return value in write context in myfilename line 2 What does that mean. And one more thing, on the code where it says if( !isset( $_SESSION['userName'] ) ) Does that mean that in this code <form name="form1" method="" action=""> the method is session?
