PHP w/ an HTML form. I'm a newbie.

[Anon]

I have a PHP module that includes a config file, which supplies a value needed by the main file in the program. Unfortunately, right now, that variable in 'config.php' is hard coded. I wanted to make it so the user can change it, so I put an HTML 'SELECT' drop down box on the page with a submit button, but I'm having issues now with where to put the 'form' tags. Depending on where I put them, content generated by the rest of the code in that file may or may not show up.

In short, what I wanna do is have the select list change the value of that variable in 'config.php', then refresh the current page ('index.php') using the variable's new value.

I hope I'm explaining this ok. I'm kinda new to PHP.

<?php
//if the form is submited then set the variable you got from the form to $var and then print it.

if($submit)
{
$var = $formvar;
print("$formvar");
}

//if it is not submited then print the form so you can submit it.

if(!$submit)
{
?>
<form method="post" action="<?php echo PHP_SELF ?>">
<input type="text" name="formvar">
<input type="submit" name="submit">
</form>
<?php
}
<?

i think that should work. i dont remember the drop down html tag off hand so i just used a text one.. but i think that is what you want.
