ok guys, jejeje, im developing 3 website, yes im overload , im tired, im lost, im not here!!, but im trying now to fix a bug,s in a editing function, the problem is that i have a lot of function like this... but i saw all my functions, and my problem is that i want to upload a file or not, if the user try to upload is fine, or if the user dont want to upload a file is fine too... now im testing and dont work in any case:

Code:

function editar__articulo(){ //function para actualizar articulo
    
    if($this->form_validation->run('articulo') == FALSE){ // VALIDACION DE CAMPOS VACIOS
    
    $data['titulo'] = "Bienvenido al panel de administracion";
        $data['main_admin'] = "dashboard/editar_articulo";
        $data['categorias'] = $this->modcategorias->listar_categorias();
        $data['articulo'] = $this->modarticulos->_editar($this->input->post('id'));
        $this->load->vars($data);
        $this->load->view('dashboard/main_admin');
        
    }else{
        
        if(!empty($_FILES['userfile']['tmp_name'])){
            
            echo "[removed]alert('with file');[removed]";
            
        }else{
            
            echo "[removed]alert('without file');[removed]";
            
        }
        
        
    } // VALIDACION DE CAMPOS VACIOS
}

this if is wrong of my way to validate the if file is sending is wrong?

Thanks u
