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
controllers/hello.php
<?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";
}
$this->view->render('hello/upload');
}
}
?>
models/hello_model.php
<?php
class Hello_Model extends Model
{
public function __construct()
{
parent::__construct();
}
public function file_details($data)
{
$this->db->insert('image_table', $data);
}
}
?>
Here is the view file upload.php which inside views folder contains the form.
views/hello/upload.php
<!DOCTYPE html>
<html>
<body>
<form method="post" action="multi_file_upload" enctype="multipart/form-data">
<input type="file" name="image[]" multiple="multiple" >
<p align="center"><button type="submit" class="btn btn-warning" id="butsave" name="submit">Submit<span class="glyphicon glyphicon-send"></span></button></p>
</form>
</body>
</html>
