Uploading file in a form on codeigniter - php

Question

I have tried all solutions but I can't tell what's wrong. Codeigniter keeps telling me that there's no file uploaded. I created the folder at the root of the project. I've seen other similar questions but I can't manage to make it work with their solutions.
This is my controller:
public function index() {
$this->form_validation->set_rules('name', 'name', 'required|trim|max_length[45]');
$this->form_validation->set_rules('type_id', 'type', 'required|trim|max_length[11]');
$this->form_validation->set_rules('stock', 'stock', 'required|trim|is_numeric|max_length[11]');
$this->form_validation->set_rules('price', 'price', 'required|trim|is_numeric');
$this->form_validation->set_rules('code', 'code', 'required|trim|max_length[45]');
$this->form_validation->set_rules('description', 'description', 'required|trim|max_length[45]');
$this->form_validation->set_rules('active', 'active', 'required|trim|max_length[45]');
$this->form_validation->set_rules('unit_id', 'unit', 'required|trim|max_length[45]');
$this->form_validation->set_rules('userfile', 'File', 'trim');
$this->form_validation->set_error_delimiters('<br /><span class="error">', '</span>');
if ($this->form_validation->run() == FALSE) { // validation hasn't been passed
$this->load->view('product/add_view');
} else { // passed validation proceed to post success logic
// build array for the model
$form_data = array(
'name' => set_value('name'),
'type_id' => set_value('type_id'),
'stock' => set_value('stock'),
'price' => set_value('price'),
'code' => set_value('code'),
'description' => set_value('description'),
'active' => set_value('active'),
'unit_id' => set_value('unit_id')
);
$config = array(
'upload_path' => "./uploads/",
'allowed_types' => "gif|jpg|png|jpeg",
'overwrite' => TRUE,
'max_size' => "2048000", // Can be set to particular file size , here it is 2 MB(2048 Kb)
'max_height' => "768",
'max_width' => "1024"
);
$this->load->library('upload', $config);
$this->upload->initialize($config); //Make this line must be here.
$imagen = set_value('userfile');
// run insert model to write data to db
if ($this->product_model->product_insert($form_data) == TRUE) { // the information has therefore been successfully saved in the db
if (!$this->upload->do_upload($imagen)) {
$error = array('error' => $this->upload->display_errors());
$this->load->view('product/add_view', $error);
} else {
$data = array('upload_data' => $this->upload->data());
$this->load->view('product/add_view', $data);
}
} else {
redirect('products/AddProduct', 'refresh');
// Or whatever error handling is necessary
}
}
}
This is my view (just showing the part that matters)
<?php // Change the css classes to suit your needs
$attributes = array('class' => '', 'id' => '');
echo form_open_multipart('products/AddProduct', $attributes); ?>
<p>
<label for="picture">Picture <span class="required">*</span></label>
<?php echo form_error('userfile'); ?>
<?php echo form_upload('userfile')?>
<br/>
</p>
<p>
<?php echo form_submit( 'submit', 'Submit'); ?>
</p>
<?php echo form_close(); ?>
EDIT: Applying the modification from the answer I get an error 500.

I tried to work on your code. and it worked on me after this changes
$config = array(
'upload_path' => "./uploads/",
'upload_url' => base_url()."uploads/", // base_url()."/uploads/", //added
'allowed_types' => "gif|jpg|png|jpeg",
'overwrite' => TRUE,
'max_size' => "2048000", // Can be set to particular file size , here it is 2 MB(2048 Kb)
'max_height' => "768",
'max_width' => "1024"
);
$this->load->library('upload'); //changed
$this->upload->initialize($config); //Make this line must be here.
$imagen = userfile; // $_FILES['userfile']['name'] //changed
If you get The localhost page isn’t working localhost is currently unable to handle this request. HTTP ERROR 500 possible error on your syntax, I just add 1 more } at the end of your code. You can check phpinfo() for other information. Also, there might be a problem on your file locations maybe the address you specified or the permissions if your running this on server.
