这些是我的编码文件。这里没有上传文件。有人请帮忙。我觉得库上传无法加载，因此它停止工作。如果问题是如何克服这个问题。

Answer 1

在html中添加表单标记

<form enctype="multipart/form-data" name="" action=""></form>

Answer 2

您的代码似乎不错，没有错误。尝试以下代码检查图像上传是否可能是路径问题？复制下面的代码并放在上面

"$this->load->view('gallery');"

这是你控制器的上升功能。

if (! $this->upload->do_upload())
{
  $error = array('error' = $this->upload->display_errors());

 // uploading failed. $error will holds the errors.
}
else
{
  $data = array('upload_data' => $this->upload->data());

 // uploading successfull, now do your further actions
}

Answer 3

您可以编写上传图像服务器端代码

function do_upload()
    {
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '100';
        $config['max_width']  = '1024';
        $config['max_height']  = '768';

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

        if ( ! $this->upload->do_upload())
        {
            $error = array('error' => $this->upload->display_errors());

            print_r($error); //debug it here 

        }
        else
        {
            $data = array('upload_data' => $this->upload->data());

            $this->load->view('upload_success', $data);
        }
    }

Answer 4

问题是要上传图像的文件夹没有写入权限，因此我将该文件夹设为可写，现在工作正常。

CodeIgniter：图片未上传。
