Цитирование через массив в массиве в laravel-excel

Question

Я использую laravel-excel, чтобы попытаться загрузить CSV-файл, а затем прокрутить загруженные файлы, чтобы обновлять базу данных. Я думаю, что laravel-excel создает массив внутри массива, о котором я не знаю, как проверить и извлечь из второго уровня массивы. Есть ли в любом случае я могу получить этот код для обновления базы данных по тому, как я это делаю? Заранее спасибо.

Мой контроллер:

public function store() 
{ 

    $csv = Input::file('csv'); 
    $destinationPath = public_path().'/lists'; 
    // If the uploads fail due to file system, you can try doing public_path().'/uploads' 
    $filename = $csv->getClientOriginalName(); 
    // $extension = $csv->getClientOriginalExtension(); 
    $upload_success = Input::file('csv')->move($destinationPath, $filename); 


    Excel::load(public_path().'/lists/states.csv', function($reader) { 

     // reader methods 
     $dbseeder = $reader->select(array('state', 'total'))->get()->toArray(); 

     foreach ($dbseeder as $state => $total){ 
      DB::table('distributors') 
       ->where('state', $state) 
       ->update(array('total' => $total)); 
     } 

     print_r($dbseeder); 

}); 

print_r ($ dbseeder) дает следующее. Если я print_r ($ читателя), то куча других значений получают (все должны делать с инструментом Maatwebsite в):

Array ([0] => Array ([state] => AK [total] => 0) [1] => Array ([state] => AL [total] => 5) [2] => Array ([state] => AR [total] => 10) [3] => Array ([state] => AZ [total] => 5) [4] => Array ([state] => CA [total] => 10) [5] => Array ([state] => CO [total] => 11) [6] => Array ([state] => CT [total] => 15) [7] => Array ([state] => DC [total] => 16) [8] => Array ([state] => DE [total] => 20) [9] => Array ([state] => FL [total] => 21) [10] => Array ([state] => GA [total] => 1) [11] => Array ([state] => HI [total] => 0) [12] => Array ([state] => IA [total] => 4) [13] => Array ([state] => ID [total] => 5) [14] => Array ([state] => IL [total] => 2) [15] => Array ([state] => IN [total] => 6) [16] => Array ([state] => KS [total] => 9) [17] => Array ([state] => KY [total] => 10) [18] => Array ([state] => LA [total] => 11) [19] => Array ([state] => MA [total] => 17) [20] => Array ([state] => MD [total] => 22) [21] => Array ([state] => ME [total] => 33) [22] => Array ([state] => MI [total] => 11) [23] => Array ([state] => MN [total] => 2) [24] => Array ([state] => MO [total] => 3) [25] => Array ([state] => MS [total] => 7) [26] => Array ([state] => MT [total] => 44) [27] => Array ([state] => NC [total] => 14) [28] => Array ([state] => ND [total] => 13) [29] => Array ([state] => NE [total] => 7) [30] => Array ([state] => NH [total] => 17) [31] => Array ([state] => NJ [total] => 18) [32] => Array ([state] => NM [total] => 19) [33] => Array ([state] => NV [total] => 21) [34] => Array ([state] => NY [total] => 0) [35] => Array ([state] => OH [total] => 44) [36] => Array ([state] => OK [total] => 55) [37] => Array ([state] => OR [total] => 7) [38] => Array ([state] => PA [total] => 12) [39] => Array ([state] => RI [total] => 3) [40] => Array ([state] => SC [total] => 2) [41] => Array ([state] => SD [total] => 8) [42] => Array ([state] => TN [total] => 15) [43] => Array ([state] => TX [total] => 16) [44] => Array ([state] => UT [total] => 20) [45] => Array ([state] => VA [total] => 21) [46] => Array ([state] => VT [total] => 26) [47] => Array ([state] => WA [total] => 33) [48] => Array ([state] => WI [total] => 13) [49] => Array ([state] => WV [total] => 12) [50] => Array ([state] => WY [total] => 8)) 

Когда я var_dump на dbseeder я получаю:

array(51) { [0]=> array(2) { ["state"]=> string(2) "AK" ["total"]=> float(0) } [1]=> array(2) { ["state"]=> string(2) "AL" ["total"]=> float(5) } [2]=> array(2) { ["state"]=> string(2) "AR" ["total"]=> float(10) } [3]=> array(2) { ["state"]=> string(2) "AZ" ["total"]=> float(5) } [4]=> array(2) { ["state"]=> string(2) "CA" ["total"]=> float(10) } [5]=> array(2) { ["state"]=> string(3) "CO " ["total"]=> float(11) } [6]=> array(2) { ["state"]=> string(2) "CT" ["total"]=> float(15) } [7]=> array(2) { ["state"]=> string(3) "DC " ["total"]=> float(16) } [8]=> array(2) { ["state"]=> string(4) "DE " ["total"]=> float(20) } [9]=> array(2) { ["state"]=> string(3) "FL " ["total"]=> float(21) } [10]=> array(2) { ["state"]=> string(3) "GA " ["total"]=> float(1) } [11]=> array(2) { ["state"]=> string(3) "HI " ["total"]=> float(0) } [12]=> array(2) { ["state"]=> string(3) "IA " ["total"]=> float(4) } [13]=> array(2) { ["state"]=> string(2) "ID" ["total"]=> float(5) } [14]=> array(2) { ["state"]=> string(3) "IL " ["total"]=> float(2) } [15]=> array(2) { ["state"]=> string(4) "IN " ["total"]=> float(6) } [16]=> array(2) { ["state"]=> string(3) "KS " ["total"]=> float(9) } [17]=> array(2) { ["state"]=> string(3) "KY " ["total"]=> float(10) } [18]=> array(2) { ["state"]=> string(3) "LA " ["total"]=> float(11) } [19]=> array(2) { ["state"]=> string(4) "MA " ["total"]=> float(17) } [20]=> array(2) { ["state"]=> string(3) "MD " ["total"]=> float(22) } [21]=> array(2) { ["state"]=> string(3) "ME " ["total"]=> float(33) } [22]=> array(2) { ["state"]=> string(3) "MI " ["total"]=> float(11) } [23]=> array(2) { ["state"]=> string(3) "MN " ["total"]=> float(2) } [24]=> array(2) { ["state"]=> string(3) "MO " ["total"]=> float(3) } [25]=> array(2) { ["state"]=> string(3) "MS " ["total"]=> float(7) } [26]=> array(2) { ["state"]=> string(3) "MT " ["total"]=> float(44) } [27]=> array(2) { ["state"]=> string(3) "NC " ["total"]=> float(14) } [28]=> array(2) { ["state"]=> string(3) "ND " ["total"]=> float(13) } [29]=> array(2) { ["state"]=> string(3) "NE " ["total"]=> float(7) } [30]=> array(2) { ["state"]=> string(3) "NH " ["total"]=> float(17) } [31]=> array(2) { ["state"]=> string(3) "NJ " ["total"]=> float(18) } [32]=> array(2) { ["state"]=> string(3) "NM " ["total"]=> float(19) } [33]=> array(2) { ["state"]=> string(3) "NV " ["total"]=> float(21) } [34]=> array(2) { ["state"]=> string(3) "NY " ["total"]=> float(0) } [35]=> array(2) { ["state"]=> string(3) "OH " ["total"]=> float(44) } [36]=> array(2) { ["state"]=> string(3) "OK " ["total"]=> float(55) } [37]=> array(2) { ["state"]=> string(3) "OR " ["total"]=> float(7) } [38]=> array(2) { ["state"]=> string(3) "PA " ["total"]=> float(12) } [39]=> array(2) { ["state"]=> string(3) "RI " ["total"]=> float(3) } [40]=> array(2) { ["state"]=> string(3) "SC " ["total"]=> float(2) } [41]=> array(2) { ["state"]=> string(3) "SD " ["total"]=> float(8) } [42]=> array(2) { ["state"]=> string(3) "TN " ["total"]=> float(15) } [43]=> array(2) { ["state"]=> string(3) "TX " ["total"]=> float(16) } [44]=> array(2) { ["state"]=> string(3) "UT " ["total"]=> float(20) } [45]=> array(2) { ["state"]=> string(3) "VA " ["total"]=> float(21) } [46]=> array(2) { ["state"]=> string(3) "VT " ["total"]=> float(26) } [47]=> array(2) { ["state"]=> string(3) "WA " ["total"]=> float(33) } [48]=> array(2) { ["state"]=> string(3) "WI " ["total"]=> float(13) } [49]=> array(2) { ["state"]=> string(3) "WV " ["total"]=> float(12) } [50]=> array(2) { ["state"]=> string(3) "WY " ["total"]=> float(8) } } 

Answer 1

Вы может пошагово многомерный массив следующим образом:

foreach ($dbseeder as $k1 => $v1) { 
    if (is_array($v1)) { 
     foreach ($v1 as $k2 => $v2) { 
      /** 
      * This gives you access to $v2['state'] and $v2['total'] 
      */ 
      DB::table('distributors') 
       ->where('state', $v2['state']) 
       ->update(array('total' => $v2['total'])); 
      } 
    } 
} 

Answer 2

благодаря Дэйву и немного для себя следующий код работал:

$csv = Input::file('csv'); 
$destinationPath = public_path().'/lists'; 
    // If the uploads fail due to file system, you can try doing public_path().'/uploads' 
    $filename = $csv->getClientOriginalName(); 
    // $extension = $csv->getClientOriginalExtension(); 
    $upload_success = Input::file('csv')->move($destinationPath, $filename); 


    Excel::load(public_path().'/lists/states.csv', function($reader) { 

     // reader methods 
     $dbseeder = $reader->select(array('state', 'total'))->get()->toArray(); 
     foreach ($dbseeder as $k1 => $v1) { 
      if (is_array($v1)) { 
       foreach ($v1 as $k2 => $v2) { 
        // print_r($k2); 
        // print_r($v2); 
        DB::table('distributors') 
         ->where('state', $v1['state']) 
         ->update(array('total' => $v1['total'])); 
        } 
       } 
      } 

    $allstates = DB::table('distributors')->lists('state'); 
    $alltotals = DB::table('distributors')->lists('total'); 

    return View::make('create') 
    ->with(compact('allstates')) 
    ->with(compact('alltotals')); 

}
