我怎么能为一个用户而不是另一个用户上传画廊图像？

Question

我正在网站上创建一个图库，并创建了多个测试帐户，以确保它们适用于每个帐户。 但是我似乎只能为一个用户，而不是其他任何用户，将任何图像上传到屏幕和图库数据库。 为什么会这样-每个用户都有自己的会话，所以我很困惑。 请看一下我的代码。 我的想法是模型中的putGalleryImage函数出了点问题，但我看不到任何真正突出的东西。 我想我的上传功能的else语句中也可能包含图片的上传时间，但是再一次，我什么也没露出来，因为如果它仅适用于一个特定用户，为什么不适用其他用户呢？

控制器：

class Gallery extends CI_Controller {

function __construct()
{
    // Call the parent construct
    parent::__construct();

    $this->load->model("profiles");
    $this->load->model("gal_model");
    $this->load->helper(array('form', 'url'));

    $this->gallery_path = 'web-project-jb/assets/gallery/';

}

function upload()
{

    $config = array(

            'allowed_types' =>'gif|jpg|jpeg|png',
            'upload_path' => $this->gallery_path,
            'max_size' => 10000,
            'max_width' => 1024,
            'max_height' => 768);

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

    $username = $this->session->userdata('username');

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

        $username = $this->session->userdata('username');

        $viewData['username'] = $username;

        $viewData['images'] = $this->gal_model->getGalleryImage($username);

        $this->load->view('shared/header');
        $this->load->view('gallery/galtitle', $viewData);
        $this->load->view('shared/nav');
        $this->load->view('gallery/galview', $error, $viewData, array('error' => ' ' ));
        $this->load->view('shared/footer');



    }
    else
    {
        $file_data  = $this->upload->data();

        $galleryImage = $this->gallery_path.$file_data['file_name'];

        $data['galleryImage'] = $this->gallery_path.$file_data['file_name'];

        $this->username = $this->session->userdata('username');

        $images = $this->session->userdata('images');

        $data['images'] = $images;

        $this->gal_model->putGalleryImage($username, $galleryImage);

        $viewData['username'] = $username;

        $viewData['images'] = $this->gal_model->getGalleryImage($username);

        var_dump($galleryImage);




        $username = $this->session->userdata('username');

        $this->load->view('shared/header');
        $this->load->view('gallery/galtitle', $viewData);
        $this->load->view('shared/nav');
        $this->load->view('gallery/galview', $viewData);
        $this->load->view('shared/footer');


    }
}

function index()
{

    $username = $this->session->userdata('username');


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

    $data['gal_model'] = $this->gal_model->getGalleryImage($username);

    $viewData['username'] = $username;
    $viewData['images'] = $this->gal_model->getGalleryImage($username);

    $this->load->view('shared/header');
    $this->load->view('gallery/galtitle', $viewData);
    $this->load->view('shared/nav');
    $this->load->view('gallery/galview', $viewData, array('error' => ' ' ));
    $this->load->view('shared/footer');

}

 }

模型：

class Gal_model extends CI_Model
{
var $gallery_path;


function Gal_model()
{
    parent::__construct();


}   


function exists($username)
{
    $this->db->select('*')->from("gallery")->where('user', $username);
    $query = $this->db->get();

    if ($query->num_rows() > 0)
    {

        return true;
        /*
         echo "user $user exists!";
        $row = $query->row();
        echo " and his profileimage is $row->profileimage";
        */
    }

    else

    {

        return false;
        //echo "no such user as $user!";
    }

}



function putGalleryImage($username, $galleryImage)
{


    $record = array('user' => $username, 'galleryimage' => $galleryImage);
    $this->session->set_userdata($galleryImage);
    if ($this->exists($username))
    {
        $this->db->where('user', $username)->insert('gallery', $record);


    }


}

function getGalleryImage($username)

    $this->db->select('*')->from('gallery')->where('user', $username);

    $imagesSet= $this->db->get();

    $images = array();

    foreach ($imagesSet->result() as $row)
    {
        $images[] = array('imageid' => $row->imageid,
                'user' => $row->user,
                'galleryimage' => $row->galleryimage);
    }
    return $images;


}

 }

视图：

 <div id="gallery">
   <?php if (isset($images) && is_array($images)):
    foreach($images as $galleryImage):
    $link = $galleryImage['galleryimage'] ?>
   <div class="thumb">
        <img src="<?php  echo base_url().$link; ?>" width='150' height='100'/>
       <br>
   </div>
<?php endforeach; else:  ?>
    <div id = "blank_gallery">Please upload an Image</div>
<?php endif; ?>

   <?=form_open_multipart('gallery/upload');?>
    <?=form_upload("userfile");?>
    <?=form_submit('upload', 'Upload')?>
    <?=form_close();?>
    <?php if (isset($error)) echo $error;?>

似乎是与目录访问有关的操作系统问题。
