I use an assoc. array that matches the form inputs, for example:
$FormDisplayData = array(
'username' => '',
'email' => '',
'city' => ''
);
and a flag variable that is set when an error is encountered.
Then in the form:
echo "Enter your username: <input type=\"text\"
name=\"username\"
value=\"{$FormDisplayData['name']}\">";
if ($FoundErrors) { echo "Invalid username!";}
and so on.
This way, first time through the form the array is empty and the error flag
is false - user gets a form ready to be filled in. If you get a processing
error, populate the $FormDisplayData array with the values from $_POST, and
the user gets his input back to correct, and a message telling him why.
Neat, huh?
There are undoubtedly many other ways to do this, but this is the only one I
know :)
Hope this helps.
