<?php $this->load->view("admin/v_footer");?>
library
<?php
error_reporting(0);
class Csv_impot {
var $csvfile, $delimitatore, $nometable;
var $_FIELD;
function csv_import($cf = "", $del = "", $nt = "") {
$this->csvfile = $cf;
$this->delimitatore = $del;
$this->nometable = $nt;
}
function export() {
$csvhandle = file($this->csvfile);
$field = explode($this->delimitatore, $csvhandle[0]);
$kolom = "";
foreach ($field as $array_kolom) {
$kolom.="`" . trim($array_kolom) . "`,";
}
$kolom = trim(substr($kolom, 0, -1));
//echo $kolom;
for ($i = 1; $i <= count($csvhandle); $i++) {
$valori = explode($this->delimitatore, $csvhandle[$i]);
$values = "";
foreach ($valori as $val) {
$val = trim($val);
if (eregi("NULL", $val) == 0)
$values.="'" . addslashes($val) . "',";
else
$values.="NULL,";
}
$values = trim(substr($values, 0, -1));
$query = "INSERT INTO " . $this->nometable . "(" . $kolom . ") values(" . trim($values) . ");";
$QUERY[$i] = $query;
}
return $QUERY;
}
}
controller
function import_dosen()
{
$this->data['title']="Import Data Dosen";
$this->load->view("admin/v_import_dosen", $this->data);
}
function save_dosen()
{
if(isset($_FILES['csv_dosen']['name']))
{
$csv_dosen=$_FILES['csv_dosen']['name'];
$handle = fopen($csv_dosen,"r");
$this->load->library('csv_import');
$csv=new csv_import(".$handle.",",","dosen");
$query=$csv->export();
$this->m_dosen->eksekusi($query);
// $check_file= explode(".", $csv_dosen);
// if(strtolower($check_file[1])=="csv")
// {
// $csv_dosen=$_FILES['csv_dosen']['temp_name'];
// $handle = fopen($csv_dosen,"r");
// while (($data = fgetcsv($handle, 1000,",")) !== FALSE)
// {
// echo "haha";
// }
// }
// else{echo "bukan file csv";}
//$handle = fopen($csv_dosen,"r");
//$csv_dosen_type=$_FILES['csv_dosen']['type'];
//$csv_dosen_size=$_FILES['csv_dosen']['size'];
}
//echo $handle;
}
models
<?php
class M_dosen extends CI_model
{
function __contruct()
{
parent::__construct();
}
function eksekusi($query)
{
//echo "<br/>";
//echo count($query);
for($i=1;$i<count($query);$i++)
{
$this->db->query($query[$i]);
//echo $query[$i];
//echo "<br/>"
}
}
}
?>
when I run this code, an erro display that [function.fopen]: failed to open stream: No such file or directory.
How I solved this promblem?
I hope you can help to solve this problem.
Thanks.

As per your library, you have to pass file name to your Csv_impot constructor. But you are passing file Handler.
so change your code as below.
//general oops method:
$csv=new csv_import($csv_dosen,",","dosen");
//In CI,
$this->load->library('csv_import',array($csv_dosen,",","dosen")); // no need to create object again. Array of values will be parameter for constructor.
