php – Excel output with codeigniter

Posted by: admin July 12, 2020 Leave a comment

Questions:

I’m trying to get a report from my codeigniter project in excel, but I am at a complete loss on how to do it. It already works well, just would like the output in excel rather then a page.

Any tips/pointers/explanations?

thanks!

How to&Answers:

I’ll refer you to this wiki article from the codeIgniter site, or to this tutorial

Answer:

use PHPExcel Library

put the class folder in your codeigniter application library and call the PHPExcel class

this works fine with codeigniter

Answer:

If you need something quick and dirty (and potentially working in FF only), I use this JS solution:

function exportExcel(html) {
window.open('data:application/vnd.ms-excel;charset=utf-8,' + encodeURIComponent(
'<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><meta http-equiv=Content-Type content="text/html; charset=utf-8"><meta name=ProgId content=Excel.Sheet><style>body {font-family:Arial} .ean {mso-number-format:0000000000000;}</style></head><body><table>'+html.replace(/[♫^]/gi,'')+'</table></body></html>'));
}

And then following link in caption tag of the table

<a href="#" onclick="javascript:exportExcel($(this).parents(&quot;.table1&quot;).html());">Excel</a>

It will open as HTML Worksheet, which works for me. As you can see in JS funciton code, you can add styles to columns and/or replace some chars you don’t need in the output.

Simplest way to integrate PHPExcel with codeigniter

  1. First download the Php Excel from the website https://phpexcel.codeplex.com/.

  2. Then extract the copy and put in the application/third_party folder of codeignitor.

  3. Then go to the folder application/libraries and create a file and name it Excel.php. And place the below code:

    require_once APPPATH.”/third_party/PHPExcel.php”; //Change path if required.

    class Excel extends PHPExcel {
    public function __construct() {
    parent::__construct();
    }
    }

4.Now create a Controller like Export.php and in its action put the code:

$this->load->library('Excel');
$query = $this->db->get('users');

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

$objPHPExcel->setActiveSheetIndex(0);

$col = 0;
foreach ($header as $field)
{
    $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);
    $objPHPExcel->getActiveSheet()->getStyle('A1:Z1')->getFont()->setBold(true);

    $col++;
}

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

    $row++;
}

$objPHPExcel->setActiveSheetIndex(0);

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

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

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