OK, now I read examples of phpexcel. As I understand there shouldn't be any other output on page, to make proper xls-file. I think so, because when I have
echo "some output and my form for query";
$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setCreator("Administrator");
$objPHPExcel->getProperties()->setLastModifiedBy("Administrator");
$objPHPExcel->getProperties()->setTitle("test");
$objPHPExcel->getProperties()->setSubject("test");
$objPHPExcel->getProperties()->setDescription("test");
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue('A1', 'Hello');
$objPHPExcel->getActiveSheet()->SetCellValue('B2', 'world!');
$objPHPExcel->getActiveSheet()->SetCellValue('C1', 'Hello');
$objPHPExcel->getActiveSheet()->SetCellValue('D2', 'world!');
$objPHPExcel->getActiveSheet()->setTitle('Simple');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
// Redirect output to a client’s web browser (Excel5)
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="01simple.xls"');
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
echo"some other code";
And get xls, it has warnings that it doen't have css links there and moreover it puts a lot of text except Hello world!, such as links in excel file. It looks like this:
I can put all work with xls in other php file and get it with ajax, but how can I give results of query to this file? All queries should be in my main file, because I don't want to have multiple connections to database. How it is clear, what I want. Any advices?
To download xls(x) file, you have to set right headers and clean the buffer to avoid bad stream. As documentation explains you can try with this code:
//------------- Enter your code before this line --------- //
// Cleaning buffer
ob_clean();
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
/* Or you can use
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
*/
// redirect output to client browser
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="your_filename.xls"');
/* Use this for Writer Excel2007
header('Content-Disposition: attachment;filename="your_filename.xlsx"');
*/
header('Cache-Control: max-age=0');
//Start Download
$objWriter->save('php://output');
