`
Model
`
<?php

var $gallery_path;
var $gallery_path_url;
function __construct()

parent::__construct();
$this->gallery_path = realpath(APPPATH . '../images');
$this->gallery_path_url = base_url().'images/';
}
function do_upload()
{
$config = array(
'allowed_types' => 'jpg|jpeg|gif|png',
'upload_path' => $this->gallery_path,
'max_size' => 2000
);
$this->load->library('upload', $config);
$this->upload->do_upload();
$image_data = $this->upload->data();
$config = array(

$files = scandir($this->gallery_path);
$files = array_diff($files, array('.', '..', 'thumbs'));

Answer 1

You are going wrong way
$new_image_insert_data = array(
'img_path' => $this->input->post('userfile'),
'img_name' => $this->input->post('img_name')
);
File input can't get like this.
After Upload file you will get all data of uploaded file
So you can store like this
$new_image_insert_data = array(
'img_path' => $image_data['file_path'],
'img_name' => $image_data['file_name']
);
See this link

Answer 2

In your form you have input field like
<input type="file" id="userfle" name="userfle" required class="md-input" />
change it to
<input type="file" id="userfle" name="userfile" required class="md-input" />
as in model you are using userfile Not userfle.
$new_image_insert_data = array(
'img_path' => $this->input->post('userfile'),
'img_name' => $this->input->post('img_name')
);
And img_path should be your folder path with
$new_image_insert_data = array(
'img_path' => $this->gallery_path_url,
'img_name' => $this->input->post('img_name') /** if you don't want to change uploaded image file name**/
);

Answer 3

Upload code should be moved to controller. Model is only for Database
this is wrong input
$new_image_insert_data = array(
'img_path' => $this->input->post('userfile'), # Wrong
'img_name' => $this->input->post('img_name')
);
should be add this $this->gallery_path
$new_image_insert_data = array(
'img_path' => $this->gallery_path,
'img_name' => $this->input->post('img_name')
);
or
$new_image_insert_data = array(
'img_path' => $image_data['file_path'],
'img_name' => $image_data['file_name']
);
So on db, record will be
img_path -->../images'
img_name --> xyz.jpg
