thinkphp5 導出含圖片的excel表格

最近遇到一個需求，導出後臺的數據，其中有一欄是圖片也要一併導出。

首先查詢mysql獲取要導出的數據

$data=$this->model->whereIn('id',$ids)->select();
$data = collection($data)->toArray();

實例化相關導出類

$objPHPExcel = new PHPExcel();   
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objActSheet = $objPHPExcel->getActiveSheet();

設置水平居中，有幾列數據，就設置幾列

$objPHPExcel->setActiveSheetIndex(0)->getStyle('A')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('B')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('C')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('D')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('E')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('F')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('G')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('H')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('I')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('J')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('K')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('L')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->setActiveSheetIndex(0)->getStyle('M')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

設置第一列的標題值

$objActSheet->setCellValue('A1', 'ID');
$objActSheet->setCellValue('B1', '參與者');
$objActSheet->setCellValue('C1', '類型');
$objActSheet->setCellValue('D1', '活動名稱');
$objActSheet->setCellValue('E1', '類別');
$objActSheet->setCellValue('F1', '將次(稱號)');
$objActSheet->setCellValue('G1', '頒獎單位');
$objActSheet->setCellValue('H1', '級別');
$objActSheet->setCellValue('I1', '獲獎日期');
$objActSheet->setCellValue('J1', '獲獎者');
$objActSheet->setCellValue('K1', '證實材料');
$objActSheet->setCellValue('L1', '添加單位');
$objActSheet->setCellValue('M1', '添加人');

這些字段中，證實材料一列是圖片，數據庫存的是圖片地址

設置表格寬度和垂直居中

 　　　　　　// 設置個表格寬度
           $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(16);
           $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);
           $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(15);
           $objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(20);
           $objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(12);
           $objPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(12);
           $objPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(12);
           $objPHPExcel->getActiveSheet()->getColumnDimension('H')->setWidth(12);
           $objPHPExcel->getActiveSheet()->getColumnDimension('I')->setWidth(12);
           $objPHPExcel->getActiveSheet()->getColumnDimension('J')->setWidth(12);
           $objPHPExcel->getActiveSheet()->getColumnDimension('K')->setWidth(12);
           $objPHPExcel->getActiveSheet()->getColumnDimension('L')->setWidth(12);
           $objPHPExcel->getActiveSheet()->getColumnDimension('M')->setWidth(12); 
           // 垂直居中
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('A')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('B')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('C')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('D')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('E')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('F')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('G')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('H')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('I')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('J')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('K')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('L')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
           $objPHPExcel->setActiveSheetIndex(0)->getStyle('M')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

組裝數據，處理圖片

foreach($data as $k=>$v){
               $k +=2;
               $objActSheet->setCellValue('A'.$k, $v['id']);   
               $objActSheet->setCellValue('B'.$k, $participant[$v['participant']]);   
               $objActSheet->setCellValue('C'.$k, $status[$v['status']]);   
               $objActSheet->setCellValue('D'.$k, $v['name']);   
               $objActSheet->setCellValue('E'.$k, $type[$v['type']]);   
               $objActSheet->setCellValue('F'.$k, $v['prizes']);   
               $objActSheet->setCellValue('G'.$k, $v['issuing']);   
               $objActSheet->setCellValue('H'.$k,$level[$v['level']]);   
               $objActSheet->setCellValue('I'.$k, $v['dateofaward']);
               $objActSheet->setCellValue('J'.$k, $v['awardee']);    
                       
               //獲取到圖片信息  
               // 圖片生成
               $objDrawing[$k] = new \PHPExcel_Worksheet_Drawing();
               $objDrawing[$k]->setPath('.'.$v['certificatefile']);//這裏拼接 . 是由於要在根目錄下獲取
               // 設置寬度高度
               $objDrawing[$k]->setHeight(80);//照片高度
               $objDrawing[$k]->setWidth(80); //照片寬度
               /*設置圖片要插入的單元格*/
               $objDrawing[$k]->setCoordinates('K'.$k);
               // 圖片偏移距離
               $objDrawing[$k]->setOffsetX(12);
               $objDrawing[$k]->setOffsetY(12);
               $objDrawing[$k]->setWorksheet($objPHPExcel->getActiveSheet());
                   
               // 表格內容   
               $objActSheet->setCellValue('L'.$k, $optionsunit_ids[$v['optionsunit_id']]);   
               $objActSheet->setCellValue('M'.$k, $admin_ids[$v['admin_id']]);
                       
               // 表格高度
               $objActSheet->getRowDimension($k)->setRowHeight(80);
                   
}

最後給文件命名，導出下載

           $fileName = '公示表';
           $fileName = iconv("utf-8", "gb2312", $fileName);
           //重命名錶
           // $objPHPExcel->getActiveSheet()->setTitle('test');
           //設置活動單指數到第一個表,因此Excel打開這是第一個表
           $objPHPExcel->setActiveSheetIndex(0);
           header('Content-Type: application/vnd.ms-excel');
           header("Content-Disposition: attachment;filename=\"$fileName\"");
           header('Cache-Control: max-age=0');
           $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
           $objWriter->save('php://output'); //文件經過瀏覽器下載
