因为在不同浏览器之间很难处理不同的标准,所以我放弃尝试使用js或jQuery导出html表.我想知道我是否可以将html中的表重新发送回服务器并在服务器上生成.xls文件供用户下载.
$filename = "DownloadReport";
$table = $_POST['table'];
ini_set('zlib.output_compression','Off');
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate,post-check=0,pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
//the folowing two lines make sure it is saved as a xls file
header('Content-type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename='.$filename);
$objReader = PHPExcel_IOFactory::createReader('HTML');
$objPHPExcel = $objReader->load($table);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
$objWriter->save('PHP://output');
exit;
问题是我无法直接加载html表.我该怎么处理？
还有一个问题是,当我在PHP中设置标题时,单击按钮时文件不会下载.实际上,我可以查看POST响应的Header的所有属性,以及响应的内容(在FireBug中),这些都是正确的.
要将内容直接放入$objPHPExcel,您需要创建一个工作表,然后逐个单元格设置值,这不是您想要的.
要插入整个HTML表,必须从HTMLReader中读取它
$filename = "DownloadReport"; $table = $_POST['table']; // save $table inside temporary file that will be deleted later $tmpfile = tempnam(sys_get_temp_dir(),'html'); file_put_contents($tmpfile,$table); // insert $table into $objPHPExcel's Active Sheet through $excelHTMLReader $objPHPExcel = new PHPExcel(); $excelHTMLReader = PHPExcel_IOFactory::createReader('HTML'); $excelHTMLReader->loadIntoExisting($tmpfile,$objPHPExcel); $objPHPExcel->getActiveSheet()->setTitle('any name you want'); // Change sheet's title if you want unlink($tmpfile); // delete temporary file because it isn't needed anymore header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); // header for .xlxs file header('Content-Disposition: attachment;filename='.$filename); // specify the download file name header('Cache-Control: max-age=0'); // Creates a writer to output the $objPHPExcel's content $writer = PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007'); $writer->save('PHP://output'); exit;
