php form submitting empty variables

#1

May 8th, 2008

hi,
i have this code to submit a login form:

Help with Code Tags

(Toggle Plain Text)

<?php
if(!isset($aid)){
?>
you must login:<br>
<form name="form1" method="post" action="<?=$PHP_SELF?>">
  <input type="text" name="aid"><br>
  <input type="password" name="apass><br>
  <input type="submit" name="submit" value=" Login "><br>
</form>
<?php
}
else{
?>
welcome etc...
<?php
}
?>

this code was working fine until something changed on the host server and i think it was register_globals changed from on to off and after that $aid is always empty except if i specifically call it as $_POST['aid'].
my question is: is my code above considered a good code, or should i use the $_POST and assign the value to the $aid variable instead of just using $aid directly? because i have many pages that i have to change this in.
i hope my question is clear... and thank you for your time.
