我目前正在开发一个允许您上传到屏幕的画廊，我想知道我应该如何将图像保存到数据库中，以便每个选择的图像都特定于每个用户。我已经完成了个人资料图片上传，它将每个用户的文件链接保存在数据库中，现在由于我试图为每个用户保存一组图像，我不确定你将如何存储一组图像一个身份证。怎么可能做到这一点？目前我的画廊数据库有 2 个字段，用户和画廊图像，但我认为这应该成为画廊图像，因为它包含图像名称的选择。在将文件名位置存储为 varchar 之前，我的个人资料图像。请指出我应该如何在一个字段中保存一组图像，或者如果它不可能。
这是我到目前为止所拥有的：
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");
$this->load->helper(array('form', 'url'));
}
function index()
{
//The commented out lines below signify what I have so far and when I uncomment them the image will no longer upload
// At the moment the images just upload to the page
//$this->load->library('upload');
$username = $this->session->userdata('username');
//$file_data = $this->upload->data();
//$image = 'gallery_path'.$file_data['file_name'];
//$data['image'] = 'gallery_path'.$file_data['file_name'];
if($this->input->post('upload'))
{
$this->gal_model->do_upload();
}
//$this->gal_model->putGalleryImage($username, $image);
$viewData['username'] = $username;
$data['images'] = $this->gal_model->get_images();
$this->load->view('shared/header');
$this->load->view('gallery/galtitle', $viewData);
$this->load->view('shared/nav');
$this->load->view('gallery/galview', $data);
$this->load->view('shared/footer');
}
}
模型：
class Gal_model extends CI_Model
{
var $gallery_path;
var $gallery_path_url;
function Gal_model()
{
parent::__construct();
$this->gallery_path = 'web-project-jb/assets/gallery';
$this->gallery_path_url = base_url().'web-project-jb/assets/gallery/';
}
function exists($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 $user!";
}
}
//this function is aiming to put the galleryimages into the database
function putGalleryImage($username, $image)
{
$record = array('user' => $username, 'galleryimage' => $image);
//$this->session->set_userdata($image);
if ($this->exists($username))
{
$this->db->where('user', $username)->update('gallery', $record);
}
else
{
$this->db->where('user', $username)->insert('gallery', $record);
}
}
function do_upload ()
{
$config = array(
'allowed_types' => 'gif|jpg|jpeg|png',
'upload_path' => $this->gallery_path,
'max_size' => 10000
);
$this->load->library("upload", $config);
$this->upload->do_upload();
$image_data = $this->upload->data();
$config = array(
'source_image' => $image_data["full_path"],
'new_image' => $this->gallery_path. '/thumbs',
'maintain_ration' => true,
'width' => 150,
'height' => 100
);
$this->load->library("image_lib", $config);
$this->image_lib->resize();
}
function get_images()
{
$files = scandir($this->gallery_path);
$files = array_diff($files, array('.', '..', 'thumbs'));
$images = array();
foreach ($files as $file){
$images[] = array(
'url' => $this->gallery_path_url.$file,
'thumb_url' => $this->gallery_path_url.'thumbs/'.$file
);
}
return $images;
}
}
我的画廊视图：
<?php if ( is_array($images) && (count($images)>0) ):
foreach($images as $image): ?>
<div class="thumb">
<a href="<?php echo $image['url']; ?>">
<img src ="<?php echo $image['thumb_url']; ?>"/>
</a>
<br>
</div>
<?php endforeach; else: ?>
<div id = "blank_gallery">Please upload an Image</div>
<?php endif; ?>
