function index()

$this->load->view('gallery');
}
function up()
{
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '1000000';
$config['max_width'] = '10240';
$config['max_height'] = '7680';

$this->upload->do_upload('file');
$this->load->view('gallery');
}
}
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，因此它停止了工作。如果这就是问题所在，如何克服它。
在html 中添加表单标签
<form enctype="multipart/form-data" name="" action=""></form>
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', $data);
}
}
您的代码看起来不错，没有错误。试试下面的代码来检查图片上传与否可能是路径问题？复制下面的代码并放在上面
"$this->load->view('gallery');"
这是你的控制器的上行功能。
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
}
问题是要上传图像的文件夹没有写入权限，所以我将该文件夹设置为可写文件夹，现在它工作正常。
