Validation checkbox does not work

[harpreetsb]

if i use checked for a checkbox, it wont work. Since the checkbox is never posted if its not checked. so this needs a change.

It's true. As soon as possible I'll try to come back to it. Thank you.

For now you can use

<input type="hidden" name="checkbox_field_name" value="0" />
<input type="checkbox" name="checkbox_field_name" value="1" />

in your HTML view.

currently i use php empty to check for checkbox.
i have made a function
function getCheckBox($str) {
if(empty($str)){
return '0';
}
else{
return '1';
}
}

Usage
if(getCheckBox($this->input->post('acceptTerms')) == 0)
