Form method file placement

Hey!!!

I have a file that is apart of a form method:

<form method="post" action="postAction.php" enctype="multipart/form-data">

I have the postAction.php file in my view folder but its not working. I wonder should it be in the controller or model folder instead? Here are the contents of the file:

PostAction.php
<?php

// Start session
session_start();

// Include and initialize DB class
require_once 'DB.class.php';
$db = new DB();

$tblName = 'images';

// File upload path
$uploadDir = "uploads/images/";

// Allow file formats
$allowTypes = array('jpg','png','jpeg','gif');

// Set default redirect url
$redirectURL = 'profile.php';

$statusMsg = '';
$sessData = array();
$statusType = 'danger';
if(isset($_POST['imgSubmit'])){
    
     // Set redirect url
    $redirectURL = 'addEdit.php';

    // Get submitted data
    $image    = $_FILES['image'];
    $title    = $_POST['title'];
    $id        = $_POST['id'];
    
    // Submitted user data
    $imgData = array(
        'title'  => $title
    );
    
    // Store submitted data into session
    $sessData['postData'] = $imgData;
    $sessData['postData']['id'] = $id;
    
    // ID query string
    $idStr = !empty($id)?'?id='.$id:'';
    
    // If the data is not empty
    if((!empty($image['name']) && !empty($title)) || (!empty($id) && !empty($title))){
        
        if(!empty($image)){
            $fileName = basename($image["name"]);
            $targetFilePath = $uploadDir . $fileName;
            $fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);
            
            if(in_array($fileType, $allowTypes)){
                // Upload file to server
                if(move_uploaded_file($image["tmp_name"], $targetFilePath)){
                    $imgData['file_name'] = $fileName;
                }else{

header("Location: ".$redirectURL);
exit();
?>

Is this a controller or model file?
