Warning: : No such file or directory in C - php

Question

I'm working on mvc framework for a website and just want to delete old image from my image folder when i' m editing a post but get this errors:
Warning: unlink(C:\xampp\htdocs\Model View Controller2/public/images/2425.jpg): No such file or directory in C:\xampp\htdocs\Model View Controller2\app\Controller\Admin\ServicesController.php on line 72
This is my controller (when I'm editing the same image old one is deleted; its what i want for different image)
<?php
namespace App\Controller\Admin;
use Core\HTML\BootstrapForm;
use \App;
class ServicesController extends AppController{
public function __construct(){
parent::__construct();
$this->loadModel('Service');
}
public function index(){
$services = $this->Service->all();
$this->render('admin.services.index', compact('services'));
}
public function edit(){
$errors = false;
$this->loadModel('Service');
if (!empty($_POST)) {
if($_FILES['img']['size'] > 1500000){
$errors = "<strong>Ce fichier est trop lourd !</strong>";
}
if(strrchr($_FILES['img']['name'], '.') !== '.jpg'){
$errors = "<strong>L'extension de ce fichier n'est pas un .jpg !</strong>";
}
if($errors != true){
$dir = '../public/images/';
print_r($dir.$_FILES['img']['name']);
unlink($dir.$_FILES['img']['name']);
move_uploaded_file($_FILES['img']['tmp_name'], $dir.$_FILES['img']['name']);
$result = $this->Service->update($_GET['id'], array(
'titre' => $_POST['titre'],
'contenu' => $_POST['contenu'],
'img' => $dir.$_FILES['img']['name']));
}
}
$service = $this->Service->find($_GET['id']);
$services = $this->Service->extract('id', 'titre', 'contenu', 'img');
$form = new BootstrapForm($service);
$this->render('admin.services.edit', compact('services', 'form', 'errors'));
}
public function delete(){
if (!empty($_POST)) {
$result = $this->Service->delete($_POST['id']);
return $this->index();
}
}
}`
this is my view form edtit.php
<center><h1>Editer la page d'accueil Services</h1></center>
<?php if($errors): ?>
<center class="alert alert-danger">
<?= $errors; ?>
</center>
<?php endif; ?>
<form class="edit" action="" method="post" enctype="multipart/form-data">
<?= $form->input('titre', 'Titre'); ?>
<?= $form->input('contenu', 'Message', array('type' => 'textarea', 'rows' => 8)); ?>
<?= $form->input('img', 'image'); ?>
<img src="<?= $servie->img; ?>">
<?= $form->file('img', 'Choisissez une image'); ?>
<button class="btn btn-primary">Sauvegarder</button>
</form>
my ServiceTable.php
<?php
namespace App\Table;
use Core\Table\Table;
class ServiceTable extends Table{
protected $table = 'services';
/**
* Récupère les derniers article
* #return array
*/
public function last(){
return $this->query("
SELECT * FROM services");
}
}

If you want to check if the image already exists with that name, to then delete it before the upload, you could do:
if(file_exists($dir.$_FILES['img']['name'])) {
unlink($dir.$_FILES['img']['name']);
}
To prevent any warnings being thrown.
