phpExcel in codeigniter

Question

我尝试获得excel文件并将其覆盖到pdf。我更迭，但我没有看到这些数据，并告诉我不能将数据加载到PDF

这里我的代码：

 //load our new PHPExcel library 
    $this->load->library('excel'); 

    $inputFileName = 'nameoffile'; 
    $excel2 = PHPExcel_IOFactory::createReader('Excel5'); 
    $excel2 = $excel2->load($inputFileName.'.xls'); 
    $excel2->setActiveSheetIndex(0); 

    header('Pragma: public'); 
    header('Expires: 0'); 
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); 
    header('Content-Type: application/force-download'); 
    header('Content-Type: application/octet-stream'); 
    header('Content-Type: application/download'); 
    header("Content-Disposition: attachment;filename=from-template.pdf"); 
    header('Content-Transfer-Encoding: binary'); 

    $objWriter = PHPExcel_IOFactory::createWriter($excel2, 'pdf'); 
    $objWriter->save('php://output'); 

Answer 1

或许是因为没有一个PHPExcel_Writer_xls，然而，有一个PHPExcel_Writer_Excel5如果您试图编写BIFF格式.xls文件

但是，您的代码显示您正在尝试创建PDF编写器。文件名是“区分大小写”，所以打造一个PDF作家，你需要用大写来指定它

$objWriter = PHPExcel_IOFactory::createWriter($excel2, 'PDF');

不要使用相同的变量为你的读者为您电子表格

$reader = PHPExcel_IOFactory::createReader('Excel5'); 
$spreadsheet = $reader->load($inputFileName . '.xls'); 

header('Content-Type: application/pdf'); 
header('Content-Disposition: attachment;filename="from-template.pdf"'); 
header('Cache-Control: max-age=0'); 
// If you're serving to IE 9, then the following may be needed 
header('Cache-Control: max-age=1'); 

// If you're serving to IE over SSL, then the following may be needed 
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past 
header ('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified 
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1 
header ('Pragma: public'); // HTTP/1.0 

$writer = PHPExcel_IOFactory::createWriter($spreadsheet, 'PDF'); 
$writer->save('php://output'); 
die();

这个工作很有代码。所以我如何隐瞒这一点。

 //load our new PHPExcel library 
    $this->load->library('excel'); 

    $inputFileName = 'nameoffile'; 
    $reader = PHPExcel_IOFactory::createReader('Excel5'); 
    $spreadsheet = $reader->load($inputFileName . '.xls'); 

    header('Content-Type: application/xls'); 
    header('Content-Disposition: attachment;filename="from-template.xls"'); 
    header('Cache-Control: max-age=0'); 

//如果您服务到IE 9，那么下面可能需要 报头（“缓存控制：最大年龄= 1”）;

//如果您通过SSL服务于IE，则可能需要以下内容： header（'Expires：Mon，1997年7月26日05:00:00 GMT'）; （过去的日期） header（'Last-Modified：'。gmdate（'D，d M Y H：i：s'）。'GMT'）; //总是修改 header（'Cache-Control：cache，must-revalidate'）; // HTTP/1.1 header（'Pragma：public'）; // HTTP/1.0

$writer = PHPExcel_IOFactory::createWriter($spreadsheet, 'Excel5'); 
    $writer->save('php://output'); 
    die();
