How to Display Successful and Failed Data in Laravel Maatwebsites Import - laravel

Question

In my Laravel-5.8 using Maatwebsites-3.1, I am trying to update Employee Leaves into MySQL database through MS Excel.
Controller
public function import(Request $request){
$request->validate([
'file' => 'required|max:10000|mimes:xlsx,xls',
]);
$path1 = $request->file('file')->store('temp');
$path=storage_path('app').'/'.$path1;
try{
Excel::import(new LeavesImport, $path);
} catch (\Maatwebsite\Excel\Validators\ValidationException $e) {
$failures = $e->failures();
Log::error($e);
$errormessage = "";
foreach ($failures as $failure) {
$errormess = "";
foreach($failure->errors() as $error)
{
$errormess = $errormess.$error;
}
$errormessage = $errormessage." ,\n At Row ".$failure->row().", ".$errormess."<br>";
}
Session::flash('error', $errormessage);
return back();
}catch (\Illuminate\Database\QueryException $e)
{
$errorCode = $e->errorInfo[1];
if($errorCode == 1062){
Log::error($e);
DB::rollback();
Session::flash('error', 'You have a duplicate entry problem!');
}
return back();
}
Session::flash('success', 'Leave Records Imported Successfully');
return redirect()->back;
}
Below is the code for the data to be imported from the MS Excel Sheet
Import
class FirstLeaveSheetImport implements ToModel, WithHeadingRow, WithBatchInserts, WithValidation
{
protected $staffid, $leavetype, $commencementdate, $resumptiondate;
private $errors = []; // array to accumulate errors
use Importable;
return new HrLeaveRequest([
'employee_id' => $this->getStaffId(),
'leave_type_id' => $this->getLeaveType(),
'commencement_date' => $this->transformDate($row['commencement_date']),
'resumption_date' => $this->transformDate($row['resumption_date']),
'no_of_days' => $row['leave_days'],
]);
}
public function getStaffId(){
if(!empty($this->staffid)){
return HrEmployee::where('employee_code',$this->staffid)->where('company_id',Auth::user()->company_id)->pluck('id')->first();
} else {
return 0;
}
}
public function getLeaveType(){
if(!empty($this->leavetype) || !$this->leavetype){
return HrLeaveType::where('leave_type_name',$this->leavetype)->where('company_id',Auth::user()->company_id)->pluck('id')->first();
} else {
return 0;
}
}
// this function returns all validation errors after import:
public function getErrors()
{
return $this->errors;
}
public function transformDate($value, $format = 'Y-m-d')
{
try {
return \Carbon\Carbon::instance(\PhpOffice\PhpSpreadsheet\Shared\Date::excelToDateTimeObject($value));
} catch (\ErrorException $e) {
return \Carbon\Carbon::createFromFormat($format, $value);
}
}
public function batchSize(): int
{
return 200;
}
public function headingRow(): int
{
return 1;
}
}
I want to display:
The List Successful uploads
The list of failed uploads
How do I achieve this?
Thanks
