Laravel excel get total number of rows before import

问题

Straight forward question. How does one get the total number of rows in a spreadsheet with laravel-excel?

I now have a working counter of how many rows have been processed (in the CompanyImport file), but I need the total number of rows before I start adding the rows to the database.

The sheet I'm importing is almost 1M rows, so I am trying to create a progress bar.

My import:

public function model(array $row)
{
    # Counter
    ++$this->currentRow;

    # Dont create or validate on empty rows
    # Bad workaround
    # TODO: better solution
    if (!array_filter($row)) {
        return null;
    }

    # Create company
    $company = new Company;
    $company->crn = $row['crn'];
    $company->name = $row['name'];
    $company->email = $row['email'];
    $company->phone = $row['phone'];
    $company->website = (!empty($row['website'])) ? Helper::addScheme($row['website']) : '';
    $company->save();

    # Everything empty.. delete address
    if (!empty($row['country']) || !empty($row['state']) || !empty($row['postal']) || !empty($row['address']) || !empty($row['zip'])) {

        # Create address
        $address = new CompanyAddress;
        $address->company_id = $company->id;
        $address->country = $row['country'];
        $address->state = $row['state'];
        $address->postal = $row['postal'];
        $address->address = $row['address'];
        $address->zip = $row['zip'];
        $address->save();

        # Attach
        $company->addresses()->save($address);

    }

    # Update session counter
    Session::put('importCurrentRow', $this->currentRow);

    return $company;

}

My controller:

public function postImport(Import $request)
{
    # Import
    $import = new CompaniesImport;

    # Todo
    # Total number of rows in the sheet to session
    Session::put('importTotalRows');

    #
    Excel::import($import, $request->file('file')->getPathname());

    return response()->json([
        'success' => true
    ]);
}

You can use below code to calculate number of rows

Excel::import($import, 'users.xlsx');

dd('Row count: ' . $import->getRowCount());

You can check the Docs

Update

The above method was for calculating the rows which have been imported so far. In order to get number of rows which are in the sheet, you need to use getHighestRow

    Excel::load($file, function($reader) {
        $lastrow = $reader->getActiveSheet()->getHighestRow();
        dd($lastrow);
    });
