Subtracting fields from two different tables and updating the value during update in Laravel - mysql

Question

I have two different tables, table_employee and table_leave. table_employee contains fields such as emp_id, paid_vacation(In Hours), used_vacation(in Hours), while table_leave contains id, hours_spent(in Hours). please how can i deduct the hours_spent in the table_leave from used from the paid_vacation in the table_employee and then update the used_vacation in table_employee with the new value
for instance. paid_vacation =150 hours, used_vacation = 0, hours_spent= 8 hours, with this, this used_vacation should be updated to 150 -8 hours = 142 hours left. I want deduct and update back in the table.
private function saveEmployeeLeave(Request $request, $id=null){
if($id != NULL){
$employeeId = DB::table('as_tbl_employee_master')
->where('employee_id', $request->employee_id)
->get();
}
$employee_id = $request->employee_id;
$paid_vacation = $request->paid_vacation;
$used_vacation = $request->used_vacation;
$empData = new AsEmployee();
if($id !== null) {
$empData = AsEmployee::find($id);
if($empData == null) {
$errors = array('Id: ' . $id . ' not exist');
return json_encode([], 400, 'Failed', $errors);
}
}
$empData->employee_id = $employee_id;
$empData->paid_vacation = $paid_vacation;
$empData->used_vacation = $used_vacation;
$empData->save();
// $emp_id = $request->emp_id;
$emp_id = $request->emp_id;
$dept = $request->department_id;
$english_name = $request->english_name;
$department = $request->department;
$selectedLeaveType = $request->selectedLeaveType;
$application_time = date('Y-m-d H:i:s');
$date_from = $request->date_from;
$date_to = $request->date_to;
$comment = $request->comment;
$contact = $request->contact;
$hours = $request->hours;
$approval_emp_id = $request->reports_to;
$manager = $request->manager;
$status = $request->status;
$empInfo = new AsEmployeeLeave();
if($id !== null) {
$empInfo = AsEmployeeLeave::find($id);
if($empInfo == null) {
$errors = array('Id: ' . $id . ' not exist');
return json_encode([], 400, 'Failed', $errors);
}
}
$empInfo->emp_id = $emp_id;
$empInfo->department_id = $dept;
$empInfo->application_time = $application_time;
$empInfo->type = $selectedLeaveType;
$empInfo->date_from = $date_from;
$empInfo->date_to = $date_to;
$empInfo->comment = $comment;
$empInfo->requester_emp_id = $emp_id;
$empInfo->requester_sign = $english_name;
$empInfo->approval_emp_id = $approval_emp_id;
$empInfo->approval_sign = $manager;
$empInfo->contact = $contact;
$empInfo->hours = $hours;
$empInfo->status = $status;
$empInfo->save();
return $empData;
}
I called it inside this function
public function addEmpLeave(Request $request){
$responseData = $this->saveEmployeeLeave($request);
return ($responseData instanceof JsonResponse) ? $responseData : $this->sendResponse($responseData);
}

Try this :
private function saveEmployeeLeave(Request $request, $id=null){
if($id != NULL){
$employeeId = DB::table('as_tbl_employee_master')
->where('employee_id', $request->employee_id)
->get();
}
$employee_id = $request->employee_id;
$paid_vacation = $request->paid_vacation;
$used_vacation = $request->used_vacation;
$empData = new AsEmployee();
if($id !== null) {
$empData = AsEmployee::find($id);
if($empData == null) {
$errors = array('Id: ' . $id . ' not exist');
return json_encode([], 400, 'Failed', $errors);
}
}
$empData->employee_id = $employee_id;
$empData->paid_vacation = $paid_vacation;
$empData->used_vacation = $used_vacation;
$empData->save();
// $emp_id = $request->emp_id;
$emp_id = $request->emp_id;
$dept = $request->department_id;
$english_name = $request->english_name;
$department = $request->department;
$selectedLeaveType = $request->selectedLeaveType;
$application_time = date('Y-m-d H:i:s');
$date_from = $request->date_from;
$date_to = $request->date_to;
$comment = $request->comment;
$contact = $request->contact;
$hours = $request->hours;
$approval_emp_id = $request->reports_to;
$manager = $request->manager;
$status = $request->status;
$empInfo = new AsEmployeeLeave();
if($id !== null) {
$empInfo = AsEmployeeLeave::find($id);
if($empInfo == null) {
$errors = array('Id: ' . $id . ' not exist');
return json_encode([], 400, 'Failed', $errors);
}
}
$empInfo->emp_id = $emp_id;
$empInfo->department_id = $dept;
$empInfo->application_time = $application_time;
$empInfo->type = $selectedLeaveType;
$empInfo->date_from = $date_from;
$empInfo->date_to = $date_to;
$empInfo->comment = $comment;
$empInfo->requester_emp_id = $emp_id;
$empInfo->requester_sign = $english_name;
$empInfo->approval_emp_id = $approval_emp_id;
$empInfo->approval_sign = $manager;
$empInfo->contact = $contact;
$empInfo->hours = $hours;
$empInfo->status = $status;
$empInfo->save();
$empData = AsEmployee::find($empData->id);
$empData->used_vacation = (int)$paid_vacation - (int)$hours;
$empData->save();
return $empData;
}
