我正在尝试向我的项目添加一个包含已上传文件的 URL 的最终字段,如果有人能指出我扩展我的模型的写入方向吗?我已经包含了我的 codeIgniter 模型和控制器代码。
控制器:
class Canvas extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->helper(array('form', 'url'));
}
function index() {
$vars = array();
//$this->load->library('ChromePhp');
//$this->ChromePhp->log('test');
//$this->ChromePhp->log($_SERVER);
// using labels
// foreach ($_SERVER as $key => $value) {
// $this->ChromePhp->log($key, $value);
// }
// warnings and errors
//$this->ChromePhp->warn('this is a warning');
//$this->ChromePhp->error('this is an error');
$this->load->library('FacebookConnect');
$facebook=$this->facebookconnect->connect();
$vars['facebook'] = $facebook;
$user = $vars['user'] = $facebook->getUser();
$this->load->model('Users_Model');
// user already set up. Show thank you page
if($user != 0 && sizeof($_POST)>0) {
$this->do_upload();
$this->iterate_profile ($vars['user'],false,$_POST);
$this->load->view('canvas',$vars);
} else {
// user not set, show welcome message
$this->load->view('canvas',$vars);
}
}
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '20048';
$config['max_width'] = '10624';
$config['max_height'] = '10268';
$config['file_name'] = date("Y_m_d H:i:s");
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
function thank_you() {
$this->load->view('thank_you',$vars);
}
function remove() {
$vars = array();
$this->load->library('FacebookConnect');
$facebook=$this->facebookconnect->connect();
$vars['facebook'] = $facebook;
$vars['user'] = $facebook->getUser();
$this->load->model('Users_Model');
if($vars['user'] == 0) {
// user not set, redirect
redirect('/', 'refresh');
} else {
// user already set up. Remove
$this->load->model('Users_Model');
$this->Users_Model->remove($vars['user']);
}
$this->load->view('removed',$vars);
}
protected function iterate_profile ($user,$breadcrumb,$item) {
foreach($item as $key => $value) {
if(is_array($value)) {
$this->iterate_profile($user,$key,$value);
}
else {
if($breadcrumb) {
//echo '[' . $breadcrumb . '_' . $key . ']= ' . $value . ' <br />';
$key = $breadcrumb . '_' . $key;
}
if( ! $this->Users_Model->exists($user,$key)) {
// does not exist in the database, insert it
$this->Users_Model->add($user,$key,$value);
} else {
$this->Users_Model->update($user,$key,$value);
}
}
}
}
}
模型:
class Users_Model extends CI_Model {
protected $_name = 'users';
function add($id,$key,$value) {
$data = array(
'id' => $id,
'name' => $key,
'value' => $value
);
return $this->db->insert($this->_name, $data);
}
function update($id,$key,$value) {
$data = array(
'value' => $value
);
$this->db->where(array(
'id' => $id,
'name' => $key
));
return $this->db->update($this->_name, $data);
}
function exists($id,$key=null) {
if($key == null) {
$this->db->where(array(
'id' => $id
));
} else {
$this->db->where(array(
'id' => $id,
'name' => $key
));
}
$query = $this->db->get($this->_name);
if($query->num_rows() > 0) {
return true;
}
return false;
}
function remove($id) {
$data = array(
'id' => $id,
);
return $this->db->delete($this->_name, $data);
}
function all() {
$query = $this->db->get($this->_name);
$results = array();
if($query->num_rows() > 0) {
foreach($query->result() as $row) {
$results[]=$row;
}
}
return $results;
}
}
