    include APPPATH.'third_party/PHPExcel/PHPExcel.php';        
    $excelreader = new PHPExcel_Reader_Excel2007();
    $loadexcel = $excelreader->load('excel/'.$this->filename = $this -> form()); 
    $sheet = $loadexcel->getActiveSheet()->toArray(null, true, true ,true);
    $data = [];
    $numrow = 1;
    foreach($sheet as $row){
        if($numrow > 1){
            // Kita push (add) array data ke variabel data
            array_push($data, [
                'TAHUN'=>$row['A'], 
                'PROVINCEID'=>$row['B'], 
                'PROVINSI'=>$row['C'], 
                'PLAN_DESAB'=>$row['D'],

public $tablename = "X";
function upload_file($filename){
    $this->load->library('upload'); 
    
    $config['upload_path'] = './excel/';
    $config['allowed_types'] = 'xlsx';
    $config['max_size'] = '2048';
    $config['overwrite'] = true;
    $config['file_name'] = $filename;

    $this->upload->initialize($config); 
    if($this->upload->do_upload('file')){ 
        $return = array('result' => 'success', 'file' => $upload_data = $this->upload->data(), 'error' => '');
        return $return;
    }else{
        $return = array('result' => 'failed', 'file' => '', 'error' => $this->upload->display_errors());
        return $return;
    }
}

function insert_multiple($data){
    $p_tablename= $this->tablename;
    $this->db->insert_batch($p_tablename, $data);

Answer 1

i have got a solution for fix this case after search many-many hours in this stack overflow,

i use the $this->session->set_flashdata('fileName',$fileName); for get the value in one function

and use the $fileName = $this->session->flashdata('fileName'); for put that value in another function

and it's worked.

Thanks for all your attention...
