using phpexcel in codeigniter - codeigniter

Question

i am using the phpexcel library to export my report to excel file.
but i want to have my own excel file and use it with phpexcel.
here is the code i used:
public function event_reportexcel($id)
{
$this->load->library('excel');
$this->excel->setActiveSheetIndex(0);
$this->excel->getActiveSheet()->setTitle('test worksheet');
$this->excel->getActiveSheet()->setCellValue('A1', 'This is just some text value');
$this->excel->getActiveSheet()->getStyle('A1')->getFont()->setSize(20);
$this->excel->getActiveSheet()->getStyle('A1')->getFont()->setBold(true);
$this->excel->getActiveSheet()->mergeCells('A1:D1');
$this->excel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$filename='just_some_random_name.xls'; //save our workbook as this file name
header('Content-Type: application/vnd.ms-excel'); //mime type
header('Content-Disposition: attachment;filename="'.$filename.'"'); //tell browser what's the file name
header('Cache-Control: max-age=0'); //no cache
$objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');
//force user to download the Excel file without writing it to server's HD
$objWriter->save('php://output');
}
it will put my data in a new excel file, but i need this function to use a excel file as template.

Answer 1

You can open the file and edit it as you need then save it
$fileType = 'Excel5';
$fileName = 'testFile.xls';
// Read the file
$objReader = PHPExcel_IOFactory::createReader($fileType);
$objPHPExcel = $objReader->load($fileName);
// Change the file
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A1', 'Hello')
->setCellValue('B1', 'World!');
// Write the file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, $fileType);
$objWriter->save($fileName);
