Codeigniter Image上傳

Question

我在一個項目中使用CodeIgniter幾個星期（所以要溫柔），並且在上傳圖片時遇到了一些困難。我將Uploads文件夾放置在根文件夾中，並具有以下代碼。

無論好壞，我一直跟着一個教程，努力嘗試和學習在實現此功能的同時。

控制器：

public function upload(){ 

     $config['upload_path'] = "/uploads"; 
     $config['allowed_types'] = "jpg|jpeg|gif|png|bmp"; 
     $this->load->library('upload', $config); 

     if($this->upload->do_upload()){ 

      echo "it worked"; 

      $finfo=$this->upload->data(); 
      $this->_createThumbnail($finfo['file_name']); 
      $data['uploadInfo'] = $finfo; 
      $data['thumbnail_name'] = $finfo['raw_name']. '_thumb' .$finfo['file_ext']; 
      $this->load->view('project_success'); 

     } else {echo "it didn't work";} // This is what I end up getting 

    } 

    public function _createThumbnail($filename){ 

     $config['image_library'] = "gd2";  
     $config['source_image']  = "/uploads" .$filename;  
     $config['create_thumb']  = TRUE;  
     $config['maintain_ratio'] = TRUE;  
     $config['width'] = "120";  
     $config['height'] = "80"; 
     $this->load->library('image_lib',$config); 
    } 

}

視圖：

<?php echo form_open_multipart('build/upload');?> 
<div class="row"> 
    <div class="large-12 columns"> 
     <span class="number left">3</span> 
     <h3>Project Images</h3> 
    </div> 
    <div class="large-1 columns"></div> 
    <div class="large-10 large-centered columns"> 
     <div class="row"> 
      <div class="large-8 columns"> 
        <label for="file">Add Images...</label> 
        <input type="file" name="file" id="file"><br> 
        <input class="button secondary radius wide right" type="submit" name="submit" value="Submit"> 
       <br/> 

      </div> 
     </div> 
    </div> 
    <div class="large-1 columns"></div> 
</div> 

<br/><br/> 

這些不是以它們的整體 - 我試圖僅包括分別相關的代碼的部分我的問題。如果你想讓整個視圖和控制器讓我知道。

任何人都可以提供任何幫助/建議嗎？我會非常感激！

Answer 1

試試這個$this->upload->do_upload('file');

$imgUpload1 = array('upload_data1' => $this->upload->data()); 

代替$finfo=$this->upload->data();

然後寫var_dump($imgUpload1['upload_data1']);看到的值。

讓我知道它是否有效;
