passing parameter bug?

[quote author="InsiteFX" date="1299785533"]No it's not a bug! If the value is 0 it thinks it is FALSE so it will not print 0.
You can try this below, not tested!

Code:

$this->pass['level'] = ($this->input->post('level_up') == FALSE)
    ? '0';
    : $this->input->post('level_up');

You may also need to check it for NULL.

I did several tests using isset() and empty() also.
The result is same. Seems like it's like you said, zero in php means empty or false.
I cannot use zero for status code then..

Thanks for the explanation
