Question

我想使用codeigniter上传文件，我在我创建的网页上有动态字段并给它具体的id。但是当我通过下面的代码上传文件时，我得到以下错误。这是因为它不能识别此id的文件字段但是在检查元素之后特定id的元素存在。有时大约1mb的小文件上传但是上传较大的文件会出错。

查看：

function upload_video_Data(a)
{
 var formData = new FormData($("#posting_comment_"+a)[0]);

 $.ajax({
    url: "<?php echo base_url();?>dashboard/do_upload_comment/"+a,
        type: 'POST',
        async : false,
        cache : false,
        contentType : false,
        processData:false,
        data: formData,
        success: function(data){

       },
        error: function(){                      
            alert('Error while request..');
        }
   });
}

<form name="posting_comment" id="posting_comment_<?=$row1['id']?>">
    <input type="file" name="save_movie_<?=$row1['id']?>" class="movie_field" id="movie_<?=$row1['id']?>" /> 
    <input type="hidden" name="file_m_id" value="<?=$row1['id']?>"/> 
    </span>   
    <input type="button" class="postbtn" id="submit_movie_<?=$row1['id']?>" value="Upload Video File" onclick = "return upload_video_Data(<?=$row1['id']?>)"/>  
</form>

控制器：

    public function do_upload_comment($a)
    {    
      $comment_id=$this->input->post('file_m_id');
      $output_dir = "./uploads/";
      $type="video";

      $fileName = $_FILES["save_movie_".$comment_id]["name"];
      $extn = pathinfo($fileName, PATHINFO_EXTENSION);
      if(!move_uploaded_file($_FILES["save_movie_".$comment_id]["tmp_name"],$output_dir.$fileName))
      {

         echo 'file upload';
      }
      else
      {
         echo 'file not uploaded';
      }

    }
