Note: Things to check on codeigniter 3.
Make sure the controller and model name has first letter upper case
Admin.php and class Admin extends CI_Controller {
And model Products.php and class Products extends CI_Model {
CI2 Upload http://www.codeigniter.com/userguide2/libraries/form_validation.html
CI3 Upload http://www.codeigniter.com/user_guide/libraries/file_uploading.html
Controller
<?php
class Admin extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->load->library('upload');
//$this->load->model('products');
}
public function index() {
}
public function admin_page() {
$this->form_validation->set_rules('name', 'Name', 'required');
$this->form_validation->set_rules('category', 'Category', 'required');
$this->form_validation->set_rules('description', 'Description', 'required');
if ($this->form_validation->run() == FALSE) {
$data['upload_errors'] = $this->upload->display_errors();
$this->load->view('admin_page', $data);
} else {
/*
* If userfile checks if.
*
*/
if (!empty($_FILES['userfile']['name'])) {
/*
*
* Make sure your images upload path is on the main directory
*
* application
* public
* public > images
* system
* .htaccess
* index.php
*
*/
$config['upload_path'] = './public/images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '3000';
$config['max_width'] = '0';
$config['max_height'] = '0';
$this->upload->initialize($config);
$field_name = 'userfile';
if ( ! $this->upload->do_upload($field_name)) {
$data['upload_errors'] = $this->upload->display_errors();
$this->load->view('admin_page', $data);
} else {
/*
* Using the variable below you are able to get codeigniter file upload info.
* Note: Codeigniter upload only made for one file
* $upload_data = $this->upload->data();
*
*/
$upload_data = $this->upload->data();
$data = array(
'category' => $this->input->post('category') ,
'product_name' => $this->input->post('name') ,
'description' => $this->input->post('description'),
'image' => $upload_data['file_name']
);
$this->products->add_product($data);
$data['upload_errors'] = '';
$this->load->view('admin_page', $data);
}
/*
If no image isset
*/
} else {
echo "No File Isset";
$data = array(
'category' => $this->input->post('category') ,
'product_name' => $this->input->post('name') ,
'description' => $this->input->post('description'),
'image' => 'no_image.jpg'
);
$this->products->add_product($data);
$data['upload_errors'] = '';
$this->load->view('admin_page', $data);
}
}
}
}
View
Changed input submit to button submit.
<div class="container">
<?php echo validation_errors('<div class="alert alert-danger">', '</div>'); ?>
<?php if ($upload_errors) {?>
<div class="alert alert-info"><?php echo $upload_errors;?></div>
<?php }?>
<?php echo form_open_multipart('admin/admin_page');?>
<div class="form-group">
<label>Product name</label>
<input type="text" name="name" class="form-control" value="<?php echo set_value('name');?>" size="50">
</div>
<div class="form-group">
<label>Category</label>
<input type="text" name="category" value="<?php echo set_value('category');?>" class="form-control" size="50">
</div>
<div class="form-group">
<label>Description</label>
<textarea class="form-control" name="description" rows="3"></textarea>
</div>
<div class="form-group">
<label>Image</label>
<input type="file" name="userfile" size="20">
</div>
<div class="form-group">
<button type="submit" class="btn btn-default">Save</button>
</div>
<?php echo form_close();?>
</div>
I would use codeigniter's form_open_multipart() http://www.codeigniter.com/user_guide/helpers/form_helper.html
All working my end.
