如何在codeigniter中上傳多個圖像和克里特拇指，並將其名稱與其他文件一起存儲在數據庫中

Question

我想上傳3張圖像並創建它們的縮略圖並希望將它們的名稱存儲在數據庫中。 任何想法該怎麼做。 NOte我已經閱讀了許多論壇和問題，但沒有人幫助我在數據庫中進行上傳和存儲。這裏是我爲1張圖片所做的，它會幫助我，如果我可以以同樣的方式對多張圖片進行同樣的處理修改聲明爲public function do_upload($field = 'userfile')

View

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

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

The method do_upload()， 所以你可以用它在你的代碼，如：

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(); 
} 

鑑於它應該看起來像：

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