Hi

I was using PHP sessions to create a sticky form but a
button was needed to reload the page.

I am new to Java and I have decided to do away with the button.
Using onChange="javascript:OnChange(this) to cause the
page to reload once a selection is made from a dynamic dropdown works.

The problem is the input box and other dropdown on the same page lose
their information. How can I create a sticky form that is
compatible with onChange?

Thanks

<?
 include("../priority_low_to_high_in.php");//proiority drop down
?>

You can do this. <input type="text" name="firstname" value="<?php echo $_POST['firstname']; >?">

Hi

Thanks for responding.

I will try the version of code you seggested

I did tried this before posting but the data was still lost:

<?
  <input type="text" name="reason" size="30" maxlength="60" 
     value="<?php if(! empty($_POST['reason'])){echo $_POST['reason'];} else
                   {echo"$reason";}?>">

?>

It could be my work, but I find isset() not always as reliable as empty().

I check form field because it is preloaded with information using $reason array.
