Answer 1

first check what you have here:

$employee_pid = $data_needed['Employee']['employee_id'];
debug($employee_pid);die;

I think your line here:

$data_needed['Employee']['employee_id'] =  (isset($column_string['2']))?preg_replace('/(\0|\r\n|\r|\n)+/', '', $column_string['2']):'';

You probably don't have a $column_string['2'] and it goes to : ''. Try for testing purposes to change the '' with '999' to see if it works OK, like this

$data_needed['Employee']['employee_id'] =  (isset($column_string['2']))?preg_replace('/(\0|\r\n|\r|\n)+/', '', $column_string['2']):'999';

Answer 2

Try replacing this:

if($this->BiometricLog->save($data_needed['Employee'])){

with this:

if($this->BiometricLog->save(
    array(
        $this->BiometricLog->alias => $data_needed['Employee']
    )
)){
