switch on input->post()

[eluser]Ngulo[/eluser]
hi guys ,i'm getting problems making a simple switch on $this->input->post('asd',TRUE);

i would like to switch in case it is null or is not Null ,any suggestion code?

i really don't know how to make this switch

guessing i would like something like this:

Code:

switch($this->input->post('asd'))
{
case is null:
i do this
break;

case is not null:
i do this other
break;
}

does anyone knows how to build perfectly this switch ?

thanks a lot

I don't see why you don't just use a regular if-else statement since you only have two alternatives.

Anyway, the following should work, though you should be aware that switch uses loose comparison (== and not ===), so a value of 0 or FALSE would also be considered to be NULL.

Code:

switch($this->input->post('asd')) {
  case NULL:
    //i do this
    break;
  default:
    //i do this other
}
