Can't upload file to codeigniter folder using CI Controller - php

Question

I'm making a form where the person could add a picture in it and it will show in a local directory folder and show up in sql table. But it seems that how many times that I tried the picture I tried uploading wont upload! Please help!
Controller:
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Auth extends MY_Controller {
function __construct() {
parent::__construct();
$this->load->database();
$this->load->library('session');

log_message('debug', 'CI My Admin : Auth class loaded');
}
public function index() {
$data['page'] = $this->config->item('englishlivebali_template_dir_public') . "login_form";

}else{
$file_data = $this->upload->data();
$data['img'] = base_url().'/uploads/'.$file_data['file_name'];
}
}
}
The Input Type in the form has an ID of "gambar_produk" and also has a name of "gambar_produk". The function that I am trying to use is the do_upload function. I tried searching for various ways but it still won't work. Please help!

Answer 1

Hope this will help you :
Note : your form should have attribute enctype="multipart/form-data",
better use form_open_multipart();
Relace $this->upload->do_upload() with $this->upload->do_upload('gambar_produk'), where gambar_produk is the name of file input
Your method do_upload should be like this :
public function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('gambar_produk'))
{
$error = array('error' => $this->upload->display_errors());
redirect ('student/biodata');
}else
{
$file_data = $this->upload->data();
$data['img'] = base_url().'/uploads/'.$file_data['file_name'];
}
}

Answer 2

By default do_upload expects the file to come from a form field called userfile, and the form must be of type “multipart”.
To make-it works, please change the name of the input file gambar_produk to userfile or use
if ( ! $this->upload->do_upload('gambar_produk'))
{
$error = array('error' => $this->upload->display_errors());
redirect ('student/biodata');
}else{
$file_data = $this->upload->data();
$data['img'] = base_url().'/uploads/'.$file_data['file_name'];
}
