Invalid image when using force download in codeigniter -


i use download helper in codeigneter,, when download file jpeg , open it,, becomes invalid...

what should do..

thank you...

controller

function downloadsuratelektronik($file) {     $this->load->helper('download');     $file_data = file_get_contents(base_url()."data/".$file);     $file_name = $file;     force_download($file_name, $file_data); }

model

 function getsuratkeluar(){     $data = $this->db->get('surat_keluar');     if ($data->num_rows() > 0){         foreach ($data->result() $row){             $hasil[]=$row;         }         return $hasil;     }

}

view

 <table>     <tr>     <td>file upload</td>     </tr>     <?php     foreach ($hasil $data) :     ?>     <tr>     <td><a href="<?=base_url();?>main/downloadsuratelektronik/<?=$data->link_upload?>">/<?=$data->link_upload?></a></td>     </tr>     <?php endforeach; ?>     </table>

i got same problem, fixed using other method... if u still want it

$file_name = "picture.jpg"  $file_path = "your path"  header('content-type: application/octet-stream');  header("content-disposition: attachment; filename=$file_name"); ob_clean(); flush();  readfile($file_path);
