Not getting the value from the on/off switch checkbox

As ivantcholakov said the key will only exist if it was checked. When you save the form data to your database check if the key was submitted, if it was set it to 'on' if the key was omitted set it to 'off'.

Code:

$data = $this->input->post( );

// change 1 to your 'on' value
// change 0 to your 'off' value
$data[ 'mycheckbox' ] = ( array_key_exists( 'mycheckbox', $data ) ) ? 1 : 0;
