我有一个网页,其中包含一个单选组作为您希望保存的文件格式的选项。选项是:
- .xls
- .xlsx
- .csv
除了 .csv 之外的所有工作,因为它还将页面 HTML 添加到文件的底部。
这是我正在尝试的(显示功能的代码片段):
// Creating the format
$data = $this->getQueryResults();
$objPHPExcel = new PHPExcel();
$objPHPExcel->getActiveSheet()->setTitle("Report");
$objPHPExcel->getProperties()->setCreator("me");
$objPHPExcel->getProperties()->setLastModifiedBy("me");
$objPHPExcel->getProperties()->setSubject("Report Stuff");
$objPHPExcel->getProperties()->setDescription("Report Stuff");
// Next I iterate through the data array
$objPHPExcel->getActiveSheet()->setCellValue($col.$rowNumber,$cell);
$objPHPExcel->getActiveSheet()->getColumnDimension($col)->setAutoSize(true);
// check the radio option selected for the file format
if($this->radioXLS->Checked) {
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$excel_name.'.xls"');
header('Cache-Control: max-age=0');
}
if($this->radioXLSX->Checked) {
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$excel_name.'.xlsx"');
header('Cache-Control: max-age=0');
}
if($this->radioCSV->Checked) {
ob_end_clean(); // add/removing this does nothing
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
$objWriter->setDelimiter(',');
$objWriter->setEnclosure('');
$objWriter->setLineEnding("\r\n");
$objWriter->setSheetIndex(0);
ob_end_clean(); // add/removing this does nothing
header('Content-Type: text/csv');
header('Content-Disposition: attachment;filename="'.$excel_name.'.csv"');
header('Cache-Control: max-age=0');
}
$objWriter->save('php://output');
关于为什么将页面 HTML 附加到 .csv 文件的任何想法?
附带说明一下,如果重要的话,这是一个普拉多项目
更新:
再来一点...
我有一个网页,可以生成乐谱格式的报告(思考表/网格)。在同一页面上,我可以选择将指法格式的日期保存到 Excel .xls(不知何故 .xlsx 现在不工作了,呃……)。当单击从该页面下载的文件时,用户可以选择将文件保存在 .xls .xlsx .csv 中。
这是否会导致已经渲染的网页通过以下方式添加到输出中:php://output
?
更新 - 解决方案:
是的,在查看了 excel 文件后,它还添加了网页 HTML。我还查看了输出缓冲区 PHP 函数,但仍然没有任何工作
while(ob_get_level() > 0) {
ob_end_clean();
}
if($this->radioCSV->Checked) {
header('Content-Type: text/csv');
header('Content-Disposition: attachment;filename="'.$excel_name.'.csv"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
$objWriter->setDelimiter(',');
$objWriter->setEnclosure('');
$objWriter->setLineEnding("\r\n");
$objWriter->setSheetIndex(0);
} elseif($this->radioXLSX->Checked) {
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$excel_name.'.xlsx"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
} else {
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$excel_name.'.xls"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
}
$objWriter->save('php://output');
exit();
