PHPExcel error in CodeIgniter "Unable to load the requested class: iofactory"

I'm trying to export an xls file with PHPExcel 1.7.8 + CodeIgniter 2.1.3

I have followed all the instructions from https://github.com/EllisLab/CodeIgniter/wiki/PHPExcel

but I'm getting this error



Unable to load the requested class: iofactory



and here's my Controller code

//expoxt to excel all admin data
function export_excel_admin()
{
//$data['resultsadmin'] = $this->admin_model->get_all_data_admin();
//var_dump($data['resultsadmin']);
//$this->load->view('administrator/export_excel/export_excel_admin', $data);
$query = $this->db->get('tbl_admin');

if(!$query)
return false;

// Starting the PHPExcel library
$this->load->library('excel');
$this->load->library('PHPexcel/IOFactory');

$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setTitle("export")->setDescription("none");

$objPHPExcel->setActiveSheetIndex(0);

// Field names in the first row
$fields = $query->list_fields();
$col = 0;
foreach ($fields as $field)
{
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);
$col++;
}

// Fetching the table data
$row = 2;
foreach($query->result() as $data)
{
$col = 0;
foreach ($fields as $field)
{
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $data->$field);
$col++;
}

$row++;
}

$objPHPExcel->setActiveSheetIndex(0);

$objWriter = IOFactory::createWriter($objPHPExcel, 'Excel5');

// Sending headers to force the user to download the file
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="Products_'.date('dMy').'.xls"');
header('Cache-Control: max-age=0');

$objWriter->save('php://output');

}


Ah also I have removed the "PHPExcel_" part in IOFactory.php file
any solution for this issue?

Answer

I've used PHPExcel with CodeIgniter successfully before.

All I did was drop the phpexcel folder into application/third-party and created the following wrapper library:

<?php

class Excel {

    private $excel;

    public function __construct() {
        // initialise the reference to the codeigniter instance
        require_once APPPATH.'third_party/phpexcel/PHPExcel.php';
        $this->excel = new PHPExcel();    
    }

    public function load($path) {
        $objReader = PHPExcel_IOFactory::createReader('Excel5');
        $this->excel = $objReader->load($path);
    }

    public function save($path) {
        // Write out as the new file
        $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');
        $objWriter->save($path);
    }

    public function stream($filename) {       
        header('Content-type: application/ms-excel');
        header("Content-Disposition: attachment; filename=\"".$filename."\""); 
        header("Cache-control: private");        
        $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');
        $objWriter->save('php://output');    
    }

    public function  __call($name, $arguments) {  
        // make sure our child object has this method  
        if(method_exists($this->excel, $name)) {  
            // forward the call to our child object  
            return call_user_func_array(array($this->excel, $name), $arguments);  
        }  
        return null;  
    }  
}

?>

I could then do the following in my controllers:

$this->load->library("excel");
$this->excel->load("/path/to/input.xls");
$this->excel->setActiveSheetIndex(0);
$this->excel->getActiveSheet()->SetCellValue('B2', "whatever");
$this->excel->save("/path/to/output.xls");

Hope this helps you out?
