Codeigniter 2.0:上传具有不同名称的表单输入的各种文件

我花了几个星期的时间处理这个问题，不得不向您寻求帮助，我正在使用Codeigniter 2.0，并从autoload.php加载file_upload库，但由于某些原因，文件无法上传，并且在执行do_upload函数时没有显示任何错误，这里有一个小代码，我有很多（我有大约9个文件输入，在这个例子中只显示了一个，为了你的舒适）。

<?php
    $atributos = array(
        "id" => "form_anuncio",
        "name" => "form_anuncio"
    );
    echo form_open_multipart("usuarios/GrabarAnuncio",$atributos);
?>
<div class="form-group">
    <label for="logotipo">Logotipo
        <input type="file" name="logotipo" id="logotipo" placeholder="Logotipo" />
    </label>
    <?php if (($datos_usuario["Logotipo"] != NULL) ||  ($datos_usuario["Logotipo"] != "")) { ?>
        <img src="<?php echo base_url(); ?>images/logos/<?php echo $datos_usuario["idusuario"] . "_" . $datos_usuario["Logotipo"] ?>" alt="Logotipo Usuario" class="img-responsive" />
    <?php } ?>
</div>
<div class="form-group">
    <input type="submit" name="GuardarAnuncio" id="GuardarAnuncio" value="Guardar Anuncio" />
</div>
<?php echo form_close(); ?>

控制器

public function GrabarAnuncio()
{
    $this->load->model('Usuarios_model');
    $this->Usuarios_model->Grabar_anuncio();
    $this->miperfil();
}

型号（只是摘录）

function Grabar_anuncio()
{
     /* Lot of code  */
        $directorio = './images/';
        $directorio1 = './images/logos/' . $ID . '/';
        if (!is_dir($directorio1)) {
            mkdir($directorio1, 0777, true);
        }
        $directorio2 = './images/fotos/' . $ID . '/';
        if (!is_dir($directorio2)) {
            mkdir($directorio2, 0777, true);
        }
        $directorio3 = './images/galerias/' . $ID . '/';
        if (!is_dir($directorio3)) {
            mkdir($directorio3, 0777, true);
        }
        if ($_FILES['logotipo']['name'] != "")
        {
            $config['upload_path'] = $directorio1;
            $config['allowed_types'] = 'gif|jpg|png';
            $config['max_size'] = '200';
            $config['max_width']  = '1024';
            $config['max_height']  = '768';
            $config['overwrite'] = true;
            $config['file_name'] = $_FILES['logotipo']['name'];
            $this->upload->initialize($config);
            if ( ! $this->upload->do_upload('logotipo'))
            {
                //Never Enter Here
                $serverError = true;
                print_r($this->upload->display_errors());
                exit();
            }
        }
     /* More code  */
}

在if语句之后执行此操作（括号外）：die（var_dump（$this->upload->data（）））；
