Question

我正在尝试使用phpexcel将数据导出到excel，但它返回此错误，但指定的excel文件在该位置突出显示。问题是excel文件在那个位置，但一旦它返回该错误，文件就无处可寻，我没做错的是什么？

错误：

致命错误：在C：\ server中显示消息“文件zip：//workbooks/NDQA201303001/NDQA201303001.xlsx#xl/media/nqcl1.png”的未捕获异常“异常” \ htdocs中\ NQCL \应用\ THIRD_PARTY \ PHPExcel \作家\ Excel2007中\ ContentTypes.php：216

处理过程的web脚本代码

  $objReader = PHPExcel_IOFactory::createReader('Excel2007');           

        $objPHPExcel = $objReader->load("workbooks/" . $labref . "/" . $labref . ".xlsx");
        $objPHPExcel->getActiveSheet(0)
               ->setCellValue('E22', 'Tabs/Capsule Weight')

                ->setCellValue('E23', 'No.')
                ->setCellValue('F23', 'Tabs/Capsule Weights (mg)');
$dir = "workbooks";

        if (is_dir($dir)) {

            $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
            $objWriter->save("workbooks/" . $labref . "/" . $labref . ".xlsx");


            echo 'Data exported';
        } else {
            echo 'Dir does not exist';
        }

Answer 1

如果您使用Codeigntier将查询中的数据导出到excel非常简单。你不需要php excel。所有资源都可以在Codeigniter中找到。

看看我的这个答案，这可能对你有所帮助。它将以csv格式导出数据，您可以使用xlsx更改这些数据。

使用下面的代码并根据您的要求进行更改。这很好。

<?php
include("config.php");
$result = mysql_query("SELECT * FROM recruitment" );

function xlsBOF() { 
echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);  
return; 
}
function xlsEOF() { 
echo pack("ss", 0x0A, 0x00); 
return; 
}
function xlsWriteNumber($Row, $Col, $Value) { 
echo pack("sssss", 0x203, 14, $Row, $Col, 0x0); 
echo pack("d", $Value); 
return; 
} 
function xlsWriteLabel($Row, $Col, $Value ) { 
$L = strlen($Value); 
echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L); 
echo $Value; 
return; 
}
function xlsWriteString( $Row , $Col , $Value )
{
$L = strlen( $Value );
echo pack( "ssssss" , 0x204 , 8 + $L , $Row , $Col , 0x0 , $L );
echo $Value;
return;
}

header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=export.xls ");
header("Content-Transfer-Encoding: binary ");

// XLS Data Cell
xlsBOF();
xlsWriteLabel(1,0,"Application No");
xlsWriteLabel(1,1,"Date of Application");


$xlsRow = 2;

while($row = mysql_fetch_array($result))
{
$applicationno=$row['applicationno'];
$dateofapplication=$row['dateofapplication'];

//echo $salarydetails;
xlsWriteNumber($xlsRow,0,"$applicationno");
xlsWriteNumber($xlsRow,1,"$dateofapplication");

$xlsRow++;

}

xlsEOF();
exit();

//}
?>
