method to check if the form has been sent

[wtom]

i only validate the form, if it was sent before. if i don't do it, all fields have errors on the first load.

if ($form->isSent() && $form->isValid()) { // save data }

Hi. Thanks for your contribution but I think this is not a good idea for some reasons:

• You are using the global variables $_SERVER and $_GET so it's not testable in other environments
• Only POST methods are considered, so the form returns false on GET, PUT, DELETE, etc methods
• This forces to use a $_GET['submit'] variable

I think each implementation should check whether the form has been sent or not in it's own way:

if (strtolower($_SERVER['REQUEST_METHOD']) == 'post') {
    $form->loadFromGlobals();
    if ($form->isValid()) {
        //do stuff
    }
}
