Incomplete Forms, retaining the data?

[tonynoriega]

I have a page that validates certain fields were populated....

say a users gets all 30 fields populated, except the required one....

they get the error, that says "error you must complete all fields, please go Back"....but when i tested it, all the fields are blank....

how can i fix this?

print the data back like so:

<?php echo $_POST['nameoffield'];?> or <?=$_POST['nameoffield'];?> in the 'value' attribute of the form inputs.
