File Upload function does not support HTTP & https based file path. also if u r used linux based os like ubuntu or mac to give the folder permission is 777 of all folder for ex. assets , image and product those three folder need read & write permission 777

public function do_upload()
{
        if(isset($_FILES['picture']))
        { 
             $dossier ='./assets/image/product/'; //based folder path if is inside public so u can use $dossier = './public/assets/image/product/';
             $fichier = basename($_FILES['picture']['name']);
             if(move_uploaded_file($_FILES['picture']['tmp_name'], $dossier . $fichier)) //Si la fonction renvoie TRUE, c'est que ça a fonctionné...
             {
                  echo 'Upload effectué avec succès !';
             }
             else //Sinon (la fonction renvoie FALSE).
             {
                  echo 'Echec de l\'upload !';
             }
        }
}
