here code. working.

controller

function index() {     if (isset($_post['submit']))     {         $this->load->library('upload');         //$this->uploadfile($_files['userfile']);         $files = $_files;         $cpt = count($_files['userfile']['name']);         for($i=0; $i<$cpt; $i++)         {                     $filename = $_files['userfile']['name']= $files['userfile']['name'][$i];                 $_files['userfile']['type']= $files['userfile']['type'][$i];                 $_files['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];                 $_files['userfile']['error']= $files['userfile']['error'][$i];                 $_files['userfile']['size']= $files['userfile']['size'][$i];                    $this->upload->initialize($this->set_upload_options());                 $this->upload->do_upload();                 $this->upload->data();         }     } $this->load->view("test"); } private function set_upload_options() {    //  upload image , document options     $config = array();     $config['upload_path'] = './upload_documents/';     $config['allowed_types'] = 'jpg|png|gif|jpeg|jpg|png|gif|jpeg|pdf|doc|docx|xls|xlsx';     $config['max_size'] = '0'; // 0 = no file size limit     $config['max_width']  = '0';     $config['max_height']  = '0';     $config['overwrite'] = true;       return $config; } 

these codes working , able transfer files on desired path. wondering on making model, how gonna identify file type seen codes above passed name of file on variable "$filename". if use print_r($filename), you'll see file name , it's file extension. names 1 insert 2 tables accordingly type of file.

is there code codeigniter or php code use identify file type , pass model 2 function upload_image or upload_docu? please.

so here is..

controller

function index() {     if (isset($_post['submit']))     {         $this->load->library('upload');         //$this->uploadfile($_files['userfile']);         $files = $_files;         $cpt = count($_files['userfile']['name']);         for($i=0; $i<$cpt; $i++)         {                     $_files['userfile']['name']= $files['userfile']['name'][$i];                 $_files['userfile']['type']= $files['userfile']['type'][$i];                 $_files['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];                 $_files['userfile']['error']= $files['userfile']['error'][$i];                 $_files['userfile']['size']= $files['userfile']['size'][$i];                    $this->upload->initialize($this->set_upload_options());                 $this->upload->do_upload();                 $this->upload->data();                 $ext = pathinfo($filename, pathinfo_extension);                 $img_ext_chk = array('jpg','png','gif','jpeg','jpg','png', 'gif', 'jpeg');                 if (in_array($ext,$img_ext_chk))                 {                     $this->asset->add_image($filename);                                             }                 else                 {                     $this->asset->add_document($filename);                 }         }     } } 

and model

public function add_image($filename) { $data = array ('images' => $filename); $this->db->insert('asset_images', $data); }  public function add_document($filename) { $data = array ('documents' => $filename); $this->db->insert('asset_documents', $data); }
