将图像上传到项目目录，并使用Codeigner将其他数据存储在数据库中

我正在表单中工作，将图像上传到项目文件夹中，并将其他数据存储到数据库中。当我试图提交这个表单时，数据被提交了，图像没有上传，还有一个图像被上传了，并不是所有的数据都存储在数据库中，这是我的代码

型号：

function update_news($data) {
    extract($data);
    $this->db->where('news_id', $news_id);
    $this->db->update($table_name, array('title_en' => $title_en, 'title_ar' => $title_ar,'news_date' => $news_date,'image' => $image,'is_visible' => $is_visible,'main_news' => $main_news));
    return true;
}

控制器

public function update() {
    $filename = $this->input->post('image');
    $date = DateTime::createFromFormat("Y-m-d", $this->input->post('news_date'));
    $data = array(
        'table_name' => 'news', // pass the real table name
        'news_id' => $this->input->post('news_id'),
        'title_en' => $this->input->post('title_en'),
        'title_ar' => $this->input->post('title_ar'),
        'news_date' => $this->input->post('news_date'),
        'image' => $date->format("Y") . '/' . $this->input->post('image'),
        'is_visible' => $this->input->post('is_visible'),
        'main_news' => $this->input->post('main_news')
    );
    $this->m_news_crud->update_news($data);
    $folderName = 'assets/images/press-news/2015';
    $config['upload_path'] = "$folderName";
    if (!is_dir($folderName)) {

        $data['is_visible'] = $this->input->post('is_visible');
        $data['main_news'] = $this->input->post('main_news');
        $data['news_id'] = $this->input->post('news_id');
