alle Datensätze aus Sicht in Excel-Blatt mit maatweb Paket exportiert werden soll ich in meinem Controller

public function exportAll() 
    { 
Excel::create('POs', function ($excel) 

     { 
      $excel->setTitle('Pos'); 
      $excel->sheet('POs', function ($sheet) 

      { 

       $pos = PO::all(); 
       $arr =array(); 

           foreach($pos as $po) 
           { 
            foreach ($po->mr as $m) 
             foreach ($po->suppliers as $supplier) 

             { 
              $data = array($m->mr_no, $po->po_no, $po->po_subject, 
               $po->po_issued, $po->po_total_cost, $po->po_currency, 
               $po->po_purchase_method, $po->po_payment_method, 
               $po->po_delivery_method, $po->po_confirmation, 
               $po->po_loaded_on_ideas, $supplier->vname, 
               $po->po_loaded_on_ideas, $po->po_approved_on_ideas, 
               $po->memo_to_fin, $po->po_delivery_date, 
               $po->po_mr_received_date, $po->po_mrr_received_date, 
               $po->po_invoice_received_date, $po->po_penalty, 
               $po->po_cover_invoice, $po->po_completed 

              ); 
              array_push($arr, $data); 


             } 
           } 

            $sheet->loadView('pos.pos_all_template')->with('pos',$pos); 
       // 

              }); 
        })->export('xlsx'); 
    } 

und in Routendatei die folgende Funktion verwendet i
Route :: get ('po_s/exportall', 'POsController @ exportAll');

meiner Ansicht Datei

@foreach($pos as $p) 
@foreach($p->mr as $m) 
@foreach($p->suppliers as $s) 

<tr style="color:rgb(0, 0, 0);" align="center" > 

    <th align="center" > {{ $m['mr_no'] }} </th> 
    <th align="center" > {{ $p['po_no'] }} </th> 
    <th align="center" > {{ $p['po_subject'] }} </th> 
    <th align="center" >{{ $p['po_issued'] }} </th> 
    <th align="center" >{{ $s['vname'] }} </th> 
    <th align="center" >{{ $p['po_total_cost'] }} </th> 
    <th align="center" >{{ $p['po_currency'] }} </th> 
    <th align="center" >{{ $p['po_purchase_method'] }} </th> 
    <th align="center" >{{ $p['po_payment_method'] }} </th> 
    <th align="center" >{{ $p['po_delivery_method'] }} </th> 
    <th align="center" >{{ $p['po_delivery_date'] }} </th> 
    <th align="center" >{{ $p['po_loaded_on_ideas'] }} </th> 
    <th align="center" >{{ $p['po_mr_received_date'] }} </th> 
    <th align="center" >{{ $p['po_mrr_received_date'] }} </th> 
    <th align="center" >{{ $p['po_invoice_received_date'] }} </th> 
    <th align="center" >{{ $p['po_penalty'] }} </th> 
    <th align="center" >{{ $p['po_cover_invoice'] }} </th> 
    <th align="center" >{{ $p['po_completed'] }} </th>

das Problem der i leer erhalten Excel-Datei ohne Daten

Answer 1

zuerst versuchen, diese ->dd($pos = PO::all();); oder enter code here dd ($ pos); Wenn Sie die Ausgabe erhalten dann versuchen Sie Ihre for-jeder Schleife, was Sie bekommen, wenn Sie dd(); verwenden. wenn Sie Daten erhalten dann Erstellen Excel-Blatt ist das Problem Check Code unten, wie im Schaffen Blatt

public function createDocs() 
     { 
    \Excel::create('JOBS', function($excel) { 
    $excel->sheet('2015', function($sheet) { 
     $jobs = DB::table('jobs')->get(); 
     $data = array('JOB ID','CONSIGNEE CODE','CONSIGNEE NAME','CONSIGNEE VAT NO','DESCRIPTION','VESSEL & VOYAGE','INVOICE VALUE','ETA/ATA DATE','B/L or AWB NUMBER','COMPLETE DATE','DELIVERY INVOICE VALUE','DUTY AMOUNT','TERMINAL','PAYMENT','INCOTERMS','COM INVOICE NO','COM INVOICE DATE','COM INVOICE VALUE','BANK','BANKREFNO','ORIGIN','EXPORT','TRADING','TOTAL EXPENSES','PROFIT'); 
    $sheet->fromArray(array($data),null,'A1',false,false); 

foreach($jobs as $row){ 
    $sum = DB::table('charges')->where('job_id', $row->id)->sum('amount'); 
    $consignee = DB::table('consignees')->where('id', $row->id)->first(); 
         $data=array($row->id,$consignee->code,$consignee->name,$consignee->vat_num,$row->description,$row->vessel, 
          $row->invoice_value,$row->eta_date,$row->awb_num,$row->complete_date,$row->del_inv_val,$row->duty_amount, 
          $row->terminal,$row->payment,$row->incoterm,$row->com_inv_no,$row->com_inv_date,$row->com_inv_value,$row->bank,$row->bank_ref_no, 
          $row->country_origin,$row->country_export,$row->country_trading,$sum,$row->invoice_value-$sum); 
         $sheet->fromArray(array($data),null,'A1',false,false); 
}});})->download('csv');}
