How to determine if input->post item does exist, but is zero?

[eluser]warpspasm[/eluser]
Hi Everyone,

According to the Codeigniter documentation:

$this->input->post('some_data');
The function returns FALSE (boolean) if the item you are attempting to retrieve does not exist.

But what if I want to know if the value does exist, but is zero?

Please let me know if you know how I could determine this?

Thanks

...such a shame this function doesn't return null if the item doesn't exist. Or am I missing some reason as to why false was a better choice?

Code:

if ( $this->input->post(‘some_data’) == false ) or if ( $this->input->post(‘some_data’) == 0 ) or if ( !$this->input->post(‘some_data’) )

Code:

if ( $this->input->post(‘some_data’) == false ) or if ( $this->input->post(‘some_data’) == 0 ) or if ( !$this->input->post(‘some_data’) )

The problem with this code is that if:

$this->input->post('some_data') == 0;

or

$this->input->post('some_data') doesn't exist;

You still get false back from the function. I'm looking for a way to be sure that $this->input->post('some_data') is set AND and that it is set to 0.

Does that make sense?

=== operator so it will check the datatype too, not ==

Code:

if ($this->input->post(‘some_data’) === 0)
