Hello everybody! 
I'm a beginner in PHP, and I try to make a blog by following a tutorial on YouTube (which is very well done! but as it dates from 2015, there are small things that do not work properly anymore. I have managed to fixa few bugs so far, but now I'm completely stuck...)
I try to configure a function that allows uploading an image from your hard drive to your server.
The blog uses Materialize. I took the code from the Materialize website, because the one from the tutorial did not work (anymore).
Here is my write.php file:
(I'm sorry... the comments are in french, but I can translate them if it helps (?))
Here is my write.func.php file :
The database connection is made with this main-functions.php file:
Sending post without image works well.
Sending post with an image also works, but the image is not uploaded to the "posts" directory; it is the default image: post.png, which is displayed instead...
Any idea, please ?...

Here is my write.func.php file :
Code:

/* Fonction d'envoi de l'article vers la base de données */

$req = $db->prepare($sql);
$req->execute($i);
move_uploaded_file($tmp_name,"../img/posts/".$id.$extension);
header("Location:index.php?page=post&id=".$id);
}The database connection is made with this main-functions.php file:
Code:

/* Le "session_start()" est à mettre au début de chaque page qui utilise les sessions ($_SESSION).
Il est plus sûr de l'inclure à la page "main-functions.php". */

} catch(PDOexception $e) {

}
?>Sending post without image works well.
Sending post with an image also works, but the image is not uploaded to the "posts" directory; it is the default image: post.png, which is displayed instead...
Any idea, please ?...
