Hi!
A very simple way to do this is by checking the variables of the form (the
names of fields) if they are isset() or not. To be more specific you can
even check, if any of them is empty().
In special cases like the email address, i suggest using regexp to check
if it is a valid email address.
The structure i use for this:
if (isset($name_of_submit_button) {
here comes the checking part
if (error_occures) $error = true;
}
if (isset($name_of_submit_button) && !$error) {
send the email
} else {
show the form itself
}
this is my way, but there are other good solutions out there as well.
