Anyone ever use PHPExcel before ?
I'm trying to use PHPExcel library within my CI code and i found this strange behaviour.
I want to create on-the-fly spreadsheet based on a template.
So i have to load a template, manipulate the content, and send it to the browser.
I have this file in my CI library :
excel.php
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Excel
{
public $workbook;
function __construct()
{
// PHPExcel libraries have to be in your include path !
require_once('PHPExcel.php');
require_once('PHPExcel/IOFactory.php');
}
function load()
{
// Path to the template file
$template_location = 'resources/template.xls';
$xls_reader = PHPExcel_IOFactory::createReader('Excel5');
$this->workbook = $xls_reader->load($template_location);
var_dump($this->workbook); // Yea, successfully load the data
}
function send()
{
//So far so good, now let's create the writer
$xls_writer = PHPExcel_IOFactory::createWriter($this->workbook, 'Excel5'); // Trouble maker
// Stops here, no error message, output nothing
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.xls");
header('Content-Transfer-Encoding: binary');
$xls_writer->save('php://output');
}
}
And i have this tester class in my controller :
excel_tester.php
Code:
<?php
class Excel_tester extends Controller
{
function __construct()
{
parent::__construct();
}
function test()
{
$this->load->library('excel');
$this->excel->load();
$this->excel->send();
}
}
And here goes the problem :
The template was loaded successfully. I tried to var_dump'ing the workbook object, and it outputs correctly.
The code execution stops right when i call
PHPExcel_IOFactory::createWriter(). No error messages displayed. It just stopped.
I tried to change the parameter,
so instead of "
createWriter($this->workbook, 'Excel5')", i use "
createWriter(new PHPExcel(), 'Excel5')".
No luck.
BUT, when i omit the template load code (that is, no
createReader executed in my code), the "
createWriter(new PHPExcel(), 'Excel5')" works like a charm, and it outputs the empty xls correcly.
Why is that, and how can i fix my problem here ?
Any helps will be appreciated. As far as i found, PHPExcel fits my needs the most, and i don't want to abandon this library.
