Count returns 1 when empty - El Forum - 03-10-2010

Hi
I have a series of checkboxes. I want to see how many are checked, so I do the following:
Code:
$checkboxCount = count($this->input->post("myCheckboxes"));This returns 1, even when I have not checked any of the boxes (but returns the correct number when I do check some of the boxes)
Maybe this is the wrong way to go about it, I'm not sure.
Any ideas?
Thanks
Jake

The method returns FALSE when the variable requested is not present in the array, which is what happens with checkboxes when you don't check any of them:
Code:
$checkboxes = $this->input->post("myCheckboxes");
$checkboxCount = $checkboxes === FALSE ? 0 : count($checkboxes);
