In this example we using Models, Views, Controller Structure for upload file.

Image table

Here is the Controller file hello.php which inside controllers folder

<?php
class Hello extends Controller {
function __construct() {
parent::__construct();
}
function file_upload(){
if(isset($_POST['submit']))
{
$output_dir = "public/uploads";//Path for file upload
$fileCount = count($_FILES["image"]['name']);
$RandomNum = time();
$ImageName = str_replace(' ','-',strtolower($_FILES['image']['name'][$i]));
$ImageType = $_FILES['image']['type'][$i]; //"image/png", image/jpeg etc.
$ImageExt = substr($ImageName, strrpos($ImageName, '.'));
$ImageExt = str_replace('.','',$ImageExt);
$ImageName = preg_replace("/\.[^.\s]{3,4}$/", "", $ImageName);
$NewImageName = $ImageName.'-'.$RandomNum.'.'.$ImageExt;
$ret[$NewImageName]= $output_dir.$NewImageName;
move_uploaded_file($_FILES["image"]["tmp_name"][$i],$output_dir."/".$NewImageName );
$data = array(
'image' =>$NewImageName
);
$this->model->file_details($data);
echo "Image Uploaded Successfully";
}
$this->view->render('hello/upload');
}
}
?>

models/hello_model.php

hello_model.php
