[FIXED] How to export mysql table to csv or excel file using phpExcel in CODEIGNITER

Issue

I've been searching on how to export mysql table to csv or excel file. I've seen some steps and I followed them. Is there a way on how to export the mysql table to csv or excel file using codeigniter?

I've tried this PHPExcel. But it seems not working to me.

function index()
{
    $query = $this->db->get('filter_result');

    if(!$query)
        return false;

    // Starting the PHPExcel library
    $this->load->library('PHPExcel');
    $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');
}

Solution

Here is a code I use.

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');  
class excel{

function to_excel($array, $filename) {
    header('Content-Disposition: attachment; filename='.$filename.'.xls');
    header('Content-type: application/force-download');
    header('Content-Transfer-Encoding: binary');
    header('Pragma: public');
    print "\xEF\xBB\xBF"; // UTF-8 BOM
    $h = array();
    foreach($array->result_array() as $row){
        foreach($row as $key=>$val){
            if(!in_array($key, $h)){
                $h[] = $key;   
            }
        }
    }
    echo '<table><tr>';
    foreach($h as $key) {
        $key = ucwords($key);
        echo '<th>'.$key.'</th>';
    }
    echo '</tr>';

    foreach($array->result_array() as $row){
        echo '<tr>';
        foreach($row as $val)
            $this->writeRow($val);   
    }
    echo '</tr>';
    echo '</table>';


}

function writeRow($val) {
    echo '<td>'.$val.'</td>';              
}

}
?>

Create a library with this code and call it as:

public function brandExcel() {
    $this->load->library('excel');
    $result = $this->config_model->getBrandsForExcel();
    $this->excel->to_excel($result, 'brands-excel'); 
}
