Correction:
Also, this condition: [quote] if (!isset($_POST['txtLoginName']) || empty($_POST['txtLoginName'])) [/quote] is true if and only if no form element by the name txtLoginName existed on the previous page - and on top of that, empty() does the same as isset() and apart from that also checks whether, if the variable has been set, it has a value (0, "", NULL or FALSE) that evaluates to FALSE. This condition is of course also true when the form element has existed but has no value.
