if when you post the form it posts back to the same script which
displays again then
<input name='city' type='text' value='".$_POST['city']."' class='big' /
>
will _always_ result in showing whatever has been posted in the cirty
input despite the validation - unless there is more to your code that
you have shown us. (unless the $_POST['city'] is set to '' if it is
not valid)
It also seems odd that the $errorFlag is set to false if there /is/ an
error.
You seem to suggest that it is the only field that is validated in
this way. How is it alone submitted for validation before the data is
submitted? XHR? Is it submitted along with the rest of the form, and
yet the only one that is validated.
If you want to post more, do so, it's the only way you will get the
definitive answers you want. As it stands it's really only speculation
you have got, which is why people are talking about such things as
magic quotes and so on....
