在codeigniter中保存两个具有相同名称的图像

Question

I try more and more but I am unable two save two files with different names in the database.

My code is here:

if(!empty($_FILES['image']['name']))
    {

                $config['upload_path'] = 'uploads/content/';
        $config['allowed_types'] = 'gif|jpg|jpeg|png|JPEG|PNG|GIF|bmp';

                        /*      */
              $newFileName = $_FILES['image']['name'];
              $fileExt = @array_pop(explode(".", $newFileName));
              $filename = md5(time().$newFileName).".".$fileExt;
              $config['file_name'] = $filename;
              $_POST['image'] = $filename;
                        /*      */
              $this->load->library('upload', $config);

       if((! $this->upload->do_upload('image')) && $_FILES['image']['error'] != 4)
        {
            $upload_error = $this->upload->display_errors();
            if(!empty($upload_error))
            {
             $this->session->set_flashdata('imageResponse', '<div class="alert alert-danger" role="alert">Image upload is not possible.only allowed gif or jpg or jpeg or png or gif or bmp</div>');

I search more I find for that I need to use this

 $this->upload->initialize($this->set_upload_options($filename));

before the ! $this->upload->do_upload('title_image')) && $_FILES['title_image']['error'] != 4) and

$this->upload->initialize($this->set_upload_options($filename));
before the ! $this->upload->do_upload('image')) && $_FILES['title_image']

['error'] != 4) but I that case I got error that The upload path does not appear to be valid but I am unable to do this ..

 private function set_upload_options($filename_multi)
{   
    //  upload an image options
    $config = array();
    $config['upload_path']   = 'assets/uploads/logo/';
    $config['allowed_types'] = 'gif|jpg|png|jpeg|bmp|GIF|JPG|JPEG|jpeg|BMP';
    $config['max_size']      = '30000';
    $config['overwrite']     = FALSE;
    $config['file_name'] = $filename_multi;
    return $config;
}

Please help me.

create unique filename like this

$file_extension = pathinfo($_FILES["title_image"]["name"], PATHINFO_EXTENSION);
$file_name = pathinfo($_FILES["title_image"]["name"], PATHINFO_FILENAME);
$filename = md5(time() . $file_name ) . '.' . $file_extension;
