PHP Button Lable Toggle

All,

I have the following simple code:
Code:<?php

/* conditions the 2 devotional DBs may be combined. */
/**************************************************************************/

Function get_doy () {
/******************************************************************/

Function prc_rad () {

?>

<html>
<body>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" >
<?php echo $dsp; ?>

</form>
</body>
</html>You'll see in the get_tbl function I correctly toggle the selected 'RADIO' buttons, but the $bn (Button Name) does not change and must for the processing function is looking for the Name of the SUBMIT button where:

1. Sign Up: Will add the user to the User table in the DB,
2. Login: Will query the user table for the registered user,

Somehow I'm not getting this done, which cqn still be done in the PHP codeing section, which I've done before but forgnotten how. I think the "toggle action" has to chnge to call a function, but did this probably 15-20 years back, so need help. None on the published HOWTOs gve me the right answer, and I tried 5. The only one that worked used javascript which I do not want to use.

All help appreciated.

Cheers!
