3つの画像をアップロードしてそれらの親指を作成し、それらの名前をdatabseに保存したいと思います。何をすべきか考えてください。注私は多くのフォーラムや質問を読みましたが、データベースへのアップロードと保存の両方を行うのに役立ったものはありません.1つの画像に対して行ったことは次のとおりです。ほとんど変更を加えずに複数の画像に対して同じように行うことができれば役に立ちます

View

<p>
    <label>Image 1</label>
    <input type="file" name="userfile"  value=""/>

// I want same kind of anothe two uploads say image2,image3
</p>

メソッドdo_upload()は として宣言されて public function do_upload($field = 'userfile')いるため、次のようにコードで使用できます。

private function uploads() {
   $config['upload_path'] = './images/imagegallaryslider';
   $config['allowed_types'] = 'gif|jpg|png';
   $config['max_size']  = '1000';
   $config['max_width']  = '1024';
   $config['max_height']  = '768';
   $this->load->library('upload', $config);
   //<--HERE the several images handler
   foreach (array('userfile','img1','img2' as $field) { 
    if ( ! $this->upload->do_upload($field))
    {
        $error = array('error' => $this->upload->display_errors());
        if($_FILES[$field]['name']=='')
    {
     $data['upload_error']='<strong>Error: Please, select image to upload</strong>';
    }
   else
    {
        $data['upload_error']='<strong>Error:Invalid file format or size</strong>';
    }
    return $data;
   }
   $data = array('upload_data' => $this->upload->data());
   $filename= $this->upload->data();
   $file_name=$this->upload->file_name;
   $this->create_thumb($file_name);
     // save data
   $this->ip_date = $this->admin_model->get_date_ip();
   $value_array = array('Name' => $this->input->post('name'),
                        'Image'=>$this->upload->file_name,
                     'CreatedBy' => $this->session->userdata('adminid'),
                     'CreatedDate'=>$this->ip_date->cur_date,
                     'CreatedIp'=>$this->ip_date->ip);
   $id = $this->admin_model->save('imggallaryslider',$value_array);
 }
 $this->session->set_flashdata('notification',$this->lang->line('gen_succ_added'));
 redirect(site_url('manage/img_gallaryslider/index'));
 die();
}

ビューでは、次のようになります。

<p>
  <label>Image 1</label>
  <input type="file" name="userfile"  value=""/>
  <input type="file" name="img1"  value=""/>
  <input type="file" name="img2"  value=""/> 
</p>
