I get a fatal error when I try that:
Fatal error: Can't use method return value in write context in
> /Users/hvirgen/Web/projects/virgentech/application/controllers/IndexController.php
> on line 49
I swapped it for this test, which is similar to yours:
if (!$this->getValue()) {
return true;
}
return false;
But it always returns true, even if I clicked a different submit button.
Again, this was testing on Chrome for Mac. Other browsers may behave
differently.
Do you just need to test if the form was submitted, or if a specific button
was clicked?
