Picture to database uploading not working in Codeigniter - php

Question

I'm making a website on the CodeIgniter framework so users can upload products on the website to the database. I'm trying to make a function so users can upload pictures to my database but its not really working.
Here some info:
DB table name: products
The DB table column name that I want the pictures to be stored in: product_foto
picture folder: upload
My controller:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Product extends CI_Controller {
var $data = array();
public function __construct()
{
parent::__construct();
$this->load->model('product_model');
$this->load->helper(array('form', 'url'));
}
public function product_form()
{
$save = array(
'product_naam' => $this->input->post('product_naam'),
'product_beschrijving' => $this->input->post('product_beschrijving'),
'product_categorie' => $this->input->post('product_categorie'),
'ophaal_plaats' => $this->input->post('ophaal_plaats'),
'product_foto' => $this->input->post('product_foto'),
'date_created' => date('Y-m-d'),
'date_updated' => date('Y-m-d')
);
$this->product_model->saveProduct($save);
redirect('https://kadokado-ferran10.c9users.io/AlleCadeausController');
}
public function upload(){
$config['upload_path'] = './upload/';
$config['allowed_types'] = 'jpg|jpeg|png';
$this->load->library('upload', $config);
if(!$this->upload->do_upload('file')){
$this->db->insert('products', array(
'product_foto' => $this->upload->file_name
));
$error = array('error'=>$this->upload->display_errors());
$this->load->view('product_form', $error);
}else{
$file_data = $this->upload->data();
$data['img'] = base_url().'/upload/'.$file_data['file_name'];
header('location:https://kadokado-ferran10.c9users.io/Product/');
}
}
}
My model file:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Product extends CI_Controller {
var $data = array();
My view file:
<?php echo form_open_multipart('Product/upload'); ?>
<input type="file" name="userfile" />
<div class="form-group">
<label for="name">Name</label>
<input type="text" name="name">
</div>
<input type="submit" name="submit" value="test" />
</form>
When I submit the form the picture only gets added to the upload folder but it doesn't get added into the database column..

Answer 1

Change your upload() function as follow
public function upload(){
$config['upload_path'] = './upload/';
$config['allowed_types'] = 'jpg|jpeg|png';
$this->load->library('upload', $config);
if(!$this->upload->do_upload('userfile')){
$error = array('error'=>$this->upload->display_errors());
$this->load->view('product_form', $error);
}else{
$file_data = $this->upload->data();
$this->db->insert('products', array(
'product_foto' => $file_data['file_name']
));
$data['img'] = base_url().'/upload/'.$file_data['file_name'];
header('location:https://kadokado-ferran10.c9users.io/Product/');
}
}
