3. Controller code
<?php

//Load plugin
require (APPPATH .'third_party\vendor\autoload.php');
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\IOFactory;

$this->load->view('menu_view');
$this->load->view('upload_view');
}

$config['upload_path'] = './uploads';
$config['allowed_types'] = 'xls|xlsx';
$config['overwrite'] = TRUE;
$this->load->library('upload', $config);

$error = array('error' => $this->upload->display_errors());
var_dump ($error);
}
else{
$data = array('upload_data' => $this->upload->data());
$full_path = $data['upload_data']['full_path'];
//---------Config read file content----------//
$reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx(); //Excel 2007 or higher
//$reader = new \PhpOffice\PhpSpreadsheet\Reader\Xls(); //Excel 2003
$spreadsheet = $reader->load($full_path);
$sheetData = $spreadsheet->getActiveSheet()->toArray(null, true, true, true);
//var_dump('<pre>');
//var_dump($sheetData);
$this->load->view('header_view');
$this->load->view('menu_view');
$this->load->view('upload_view', $sheetData);
}
}
}
/* End of file Upload.php */
/* Location: ./application/controllers/Upload.php */
2. View code
<?php
foreach ($sheetData as $value) {
echo $value -> A;
}
?>

Answer 1

Try this way:
$dataarr = array();
$dataarr['sheetData'] = $spreadsheet->getActiveSheet()->toArray(null, true, true, true);
$this->load->view('header_view');
$this->load->view('menu_view');
$this->load->view('upload_view', $dataarr);
I think it will help you.
