if ( $FormIsSent == "My-String ) {
process form
header( "Location: url" );
}
else {
display form
<input type = "hidden" name = "FormIsSent" value = "My-String">
}
I use this technique on my sites all the time. The only restriction is you
can't have any output before the header. If there is an error in the form,
store it in an error variable:
$error[NameForError] = "Problem with form";
then use a foreach to get the values back out
if ( count( $error ) ) {
foreach ( $error as $key=>$value ) {
print "Error with $key - $value<br>";
}
}
else {
header( "location: http://youurl.com/formsuccess.php"; );
exit;
}
