I have the code that uploads the image and store it in database, but I need to resize that image on uploading without deforming it. I'm trying not to use js, but if its needed please use, and help me.
Here is my file add_post.php:
<?php //include config
require_once('../includes/config.php');
//if not logged in redirect to login page
if(!$user->is_logged_in()){ header('Location: ../login.php'); }
?>
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Admin - Add Post</title>
<link rel="stylesheet" href="../style/normalize.css">
<link rel="stylesheet" href=".style/style.css">
<script src="//tinymce.cachefly.net/4.0/tinymce.min.js"></script>
<script>
tinymce.init({

plugins: [

"searchreplace visualblocks code fullscreen",
"insertdatetime media table contextmenu paste"
],
toolbar: "insertfile undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image"
});
</script>

$new_file_name = strtolower($file);
$final_file=str_replace(' ','-',$new_file_name);
