<title>Untitled Document</title>
</head>

Re: need help with forms and variables

I'm not totally sure what you are attempting to do, since what you say you want to do and what your code do are very different things...

Are you looking for something like this?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
</head>
<body>

    <?php
        $monster = "testing";
    ?>
    
    <form action="" name="test" method="POST">
        send to:<input type="text" name="send_to" value="<?php echo $monster; ?>" />
        <input type="submit" value="submit" />
    </form>

</body>
</html>

If so, your main issue is that you need to set the variable before the form is rendered. As my example shows, you'll just need to move the PHP code where you set your variable above your form.

Also, remember your form needs a method (either POST or GET)

Re: need help with forms and variables

Also should mention:

You shouldn't need to use this for your form's action: "<?php $_SERVER['PHP_SELF']; ?>"

If it is going to redirect to the same page on submit, you can just leave it blank like this: ""
