first you need to make a big if statement that checks if all the required are
set, if so, then process the data, if not, then type out the form and out over
that:
Check that the value is empty and the page has been submitted
if(!empty($submit) && empty($something)) {
echo "<font color=\"red\">Something: </font>";
} else {
echo "Something: ";
}
To set the value back, you need to make
<input type="text" name="something" value="<?PHP echo $something; ?>">
