无法上传图片codeigniter

Question

我想上传图片。 下面是代码

<?php 
$PerpetualCalendar = $this->input->post(); 
if($files['imgQuarter1']['name'][$key]!="") 
{ 
    $_FILES['imgQuarter1']['name']= $files['imgQuarter1']['name'][$key]; 
    $_FILES['imgQuarter1']['type']= $files['imgQuarter1']['type'][$key]; 
    $_FILES['imgQuarter1']['tmp_name']= $files['imgQuarter1']['tmp_name'][$key]; 
    $_FILES['imgQuarter1']['error']= $files['imgQuarter1']['error'][$key]; 
    $_FILES['imgQuarter1']['size']= $files['imgQuarter1']['size'][$key]; 
    if(isset($PerpetualCalendar['id1'][$key])) 
    { 
     $img_id=$PerpetualCalendar['id1'][$key]; 
    } 
    else 
    { 
     $img_id=$GetLastID; 
    } 
    $fileName = $img_id.'_NAME_'. $files['imgQuarter1']['name'][$key]; 
    $config['file_name'] = $fileName; 
    $this->upload->initialize($config); 
    if($this->upload->do_upload('imgQuarter1')) 
    { 
     if(isset($PerpetualCalendar['NAMEpath_idQ1'][$key])){ 
      $ImgUpdate[$imgkey]['tbl_name']='perpetual_calendar'; 
      $ImgUpdate[$imgkey]['field_name']='event_name'; 
      $ImgUpdate[$imgkey]['user_FK']=$user_id; 
      $ImgUpdate[$imgkey]['path']=$uploadpath.'/'.$fileName; 
      $ImgUpdate[$imgkey]['entry_id']=$img_id; 
      $ImgUpdate[$imgkey]['path_id']=$PerpetualCalendar['NAMEpath_idQ1'][$key]; //for update purpose 
     }else{ 

      $ImgInsert[$imgkey]['tbl_name']='perpetual_calendar'; 
      $ImgInsert[$imgkey]['field_name']='event_name'; 
      $ImgInsert[$imgkey]['user_FK']=$user_id; 
      $ImgInsert[$imgkey]['path']=$uploadpath.'/'.$fileName; 
      $ImgInsert[$imgkey]['entry_id']=$img_id; 
     } 
     $imgkey++; 
    } 
    else 
    { 
     $this->data['error'] = $this->session->set_flashdata(array('error' => $this->upload->display_errors())); 
    } 
} 
?> 

这里是查看

echo form_upload(array('name'=>'imgQuarter1['.$key.']','class'=>'default'),''); 
echo form_input(array('name' => 'id1['.$key.']', 'type'=>'hidden','value'=>$ValuePerpetualCalendar['cal_id'])); 

在上面的代码

，我可以得到$ PerpetualCalendar [ 'ID1'] [$关键]这个ID，但 图片无法在文件夹中上传，无法保存在数据库Aswell！

任何帮助？

public function upload_multiple_image($user_id){ 

      $image = $_FILES['image']['name']; 
      $files = $_FILES['image']; 
      $image_title = $this->input->post('image_title'); 
      $image_link = $this->input->post('image_link'); 
      foreach($image as $key=>$data){ 
       if($files['name'][$key]!=""){    
        $add_data['user_id'] = $user_id; 
        $add_data['title'] = $image_title[$key]; 
        $add_data['description'] = $image_link[$key]; 
        $add_data['status'] = 1; 
        $this->db->insert('user_images',$add_data); 
        $last_inserted_id = $this->db->insert_id(); 

        $_FILES['image']['name'] = $files['name'][$key]; 
        $_FILES['image']['type'] = $files['type'][$key]; 
        $_FILES['image']['tmp_name'] = $files['tmp_name'][$key]; 
        $_FILES['image']['error'] = $files['error'][$key]; 
        $_FILES['image']['size'] = $files['size'][$key]; 

        $config['upload_path'] = './user_images/original/'; 
        $config['allowed_types'] = 'gif|jpg|png|jpeg'; 
        $config['overwrite'] = TRUE; 
        $config['file_name'] = 'place_image_'.$last_inserted_id; 

        $this->load->library('upload', $config); 
        $this->upload->initialize($config); 

        if($this->upload->do_upload('image')){ 
         $file_details = $this->upload->data(); 
         $update_data = array('image'=>$file_details['file_name']); 
         $this->db->update('user_images',$update_data,array('id'=>$last_inserted_id)); 
        } 
       } 
      } 


     }
