I have created a website, And I don't to allowed customer to type link in browser.
I just want to allow customer click link on the website only.
please provide me a solution !!!
thank for help !!!
use token for in hyperlinks . deny if token wont match to value in session.
try the following:
in controller check if session['token'] is set,
if not set session['token'] to a rendom value.
if token not set or won't match to $_GET['token'] variable redirect to error page.
if token match to get variable (ie. $_GET['token']) then , pass that value to view.
i don't recomend this because doing this might affect the browser cache.
Controller constructor
function __construct()
{
parent::__construct();
$this->load->library('session');
if(!isset($_SESSION['token']))
{
$_SESSION['token'] = rand();
}
if((!$this->input->get('token')) || ($this->input->get('token') != $_SESSION['token']))
{
redirect('error_page');
}
// to pass to vew
$data['token'] = $_SESSION['token'];
$this->load->view('view_page',$data);
}
in view_page.php (view) replace links like this
Gallery link

I've found here some examples, but they are not answering how to redirect registered user to his own profile by id.
protected $redirectPath = '/profile/view/'.$user->id; Did not help.
I have a project where users are being authorized without email confirmation and they are sent to /home after registration.
Route to user profile is: /profile/view/id (id is unique of course).
I managed to send them there after login (in AuthController :
public function authenticated($request,$user)
{
return redirect('/profile/view/'.$user->id);
}
but redirect to profile after registration I can't handle.
Approach 1.
Let users view their own profile without ID.
route (make ID optional):
Route::get('profile/view/{id?}', ...);
controller:
public function view($id = null) {
if (is_null($id) { //set id of currently signed in user if id == null
$id = Auth::user()->id;
}
//continue as before
}
Approach 2.
Modify routes so redirect happens to correct url.
Note: order of routes is important
Route::get('profile/view', function() {
return redirect()->route('profile.view', ['id' => Auth::user()->id]);
});
Route::get('profile/view/{id}', ...)->name('profile.view');
Note: in both approaches auth middleware is a must, else you going to get error if user is not logged in (PHP error: Trying to get property of non-object on line X)
With both approaches you just redirect user to profile/view:
is shown profile (without ID in URL)
is redirected to proper url profile/view/ID.
I am trying to build a server-to-server auth flow using the Facebook PHP SDK and no Javascript, as outlined here. So far, I have successfully created a LoginUrl that lets the User sign in with Facebook, then redirect back to my App and check the state parameter for CSFR protection.
My Problem is, that I can't seem to get the API-call working that should swap my Auth Code for an access token. I pillaged every similar problem anyone else that Google was able to find had encountered for possible solutions.
Yet the end result was always the same: no access token, no error message that I could evaluate.
Researching the topic yielded the following advice, which I tested:
The URL specified in the App Settings must be a parent folder of $appUrl.
use curl to make the request instead of the SDK function api()
I've been at this for 2 days straight now and really could use some help.
<?php
require '../inc/php-sdk/src/facebook.php';
// Setting some config vars
$appId = 'MY_APP_ID';
$secret = 'MY_APP_SECRET';
$appUrl = 'https://MY_DOMAIN/appFolder';
$fbconfig = array('appId'=>$appId, 'secret'=>$secret);
$facebook = new Facebook($fbconfig);
// Log User in with Facebook and come back with Auth Code if not yet done
if(!(isset($_SESSION['login']))){
$_SESSION['login']=1;
header('Location: '.$facebook->getLoginUrl());
}
// process Callback from Facebook User Login
if($_SESSION['login']===1) {
/* CSFR Protection: getLoginUrl() generates a state string and stores it
in "$_SESSION['fb_'.$fbconfig['appId'].'_state']". This checks if it matches the state
obtained via $_GET['state']*/
if (isset($_SESSION['fb_'.$fbconfig['appId'].'_state'])&&isset($_GET['state'])){
// Good Case
if ($_SESSION['fb_'.$fbconfig['appId'].'_state']===$_GET['state']) {
$_SESSION['login']=2;
}
else {
unset($_SESSION['login']);
echo 'You may be a victim of CSFR Attacks. Try logging in again.';
}
}
}
// State check O.K., swap Code for Token now
if($_SESSION['login']===2) {
$path = '/oauth/access_token';
$api_params = array (
'client_id'=>$appId,
'redirect_uri'=>$appUrl,
'client_secret'=>$secret,
'code'=>$_GET['code']
);
$access_token = $facebook->api($path, 'GET', $api_params);
var_dump($access_token);
}
The easiest way I found to do this is to extend the Facebook class and expose the protected getAccessTokenFromCode() method:
<?php
class MyFacebook extends Facebook {
/** If you simply want to get the token, use this method */
public function getAccessTokenFromCode($code, $redirectUri = null)
{
return parent::getAccessTokenFromCode($code, $redirectUri);
}
/** If you would like to get and set (and extend), use this method instead */
public function setAccessTokenFromCode($code)
{
$token = parent::getAccessTokenFromCode($code);
if (empty($token)) {
return false;
}
$this->setAccessToken($token);
if (!$this->setExtendedAccessToken()) {
return false;
}
return $this->getAccessToken();
}
}
I also included a variation on the convenience method I use to set the access token, since I don't actually need a public "get" method in my own code.
I'm using CakePHP 2.3.1 and this plugin: https://github.com/webtechnick/CakePHP-Facebook-Plugin to implement a facebook authentication. I followed this screen cast http://tv.cakephp.org/video/webtechnick/2011/01/12/nick_baker_--_facebook_integration_with_cakephp but it doesn't work, I can't receive the Facebook user information. I mean $this->Connect->user() always return null.
First make sure your user as granted access to your app. Then make a call to retrieve personal details through the api(/me) => $this->Connect->user()
Personally, I use this
public function beforeFilter(){
if($this->Connect->FB->getUser() != 0){
$this->set('facebookUser', $this->Connect->user());
}
Initiating ConnectComponent will populate (or not) the Auth Session. If no id is to be found, redirect user to a login dialog.
Call this method from beforefilter..and save the post data received in some variable like fb_data here.
protected function _valdiateFbRequest() {
if (!isset($this->request->data['signed_request'])) {
// not a valid request from fb
// throw exception or handle however you want
return;
}
$this->signedRequest = $this->request->data['signed_request'];
$this->fb_data=$this->Connect->registrationData(); //save fb data
unset($this->request->data['signed_request']);
if (empty($this->request->data)) {
$this->Security->csrfCheck = false;
}
// validate the request
}
there is a custom login form that should give users access to certain contents on the same page. That works so far with Users stored as Members in the SS database and I was checking after Login if the user has permissions like this in the Page Class:
function isAllowed() {
if (Member::currentUser()) {
$PresseGroup = DataObject::get_one('Group', "Code = 'presse'");
$AdminGroup = DataObject::get_one('Group', "Code = 'administrators'");
if (Member::currentUser()->inGroup($PresseGroup->ID) || Member::currentUser()->inGroup($AdminGroup->ID)) {
return true;
}
}
}
in the Template I just did this:
<% if isAllowed %>
SecretContent
<% end_if %>
OK so far, but now the users will not be stored in the silverstripe database - they are stored on a another server.
On that external server is running a little php script accepting the username and password. The script just returns user has permission: true or false.
I´m calling that script via cURL.
I planned to overwrite the dologin Function of MemberLoginForm. Now I just wonder how to check after Login that the User got the permission and display the contents... I tried to set a variable in the controller of the Page or should I set a session Variable? Thats my attempt (CustomLoginForm extends MemberLoginForm):
public function dologin($data) {
if(userHasPermission("user1", "pw")==true){
$this->controller->Test("test");
}
$link = $this->controller->Link();
$this->performLogin($data);
$this->controller->redirect($link);
}
I hope someone can help me with that - I know very specific - problem.
Many thanx,
Florian
In SilverStripe you can create a custom authenticator, which means users can log in on your website with accounts that are stored somewhere else, or even just a hard coded user and password.
You can check out the OpenID Authentication Module for example code on how to do it
But for your task this might even be to complex of a solution, how about after login just do something like Session::set('isAllowed', true); and to check if the user is allowed to view:
function isAllowed() {
if (Member::currentUser()) {
$PresseGroup = DataObject::get_one('Group', "Code = 'presse'");
$AdminGroup = DataObject::get_one('Group', "Code = 'administrators'");
if (Member::currentUser()->inGroup($PresseGroup->ID) || Member::currentUser()->inGroup($AdminGroup->ID)) {
return true;
}
}
// if Member::currentUser() is not allowed to view,
// return the session, which is either set to true or it returns null if not set
return Session::get('isAllowed');
}
I am iterating through some data and generating parameterized URL links based on some conditions like this:
finishedHTML.append("<a href=\"http://" + domain + "&service=" + allEvents[eventCounter].EventService +"&day="+ offSet+(-1 * i) +"\"><img src=\"/info.jpg\" alt=\"Info\"/>");
I had the beginning of my application checking for URL parameters when the page was loaded/refreshed, and take some action depending on if the parameters were there and what they were.
However, I added a # to the beginning of the paramters, so the page wouldn't need to be refreshed, but now it's not triggering the function that checks the URL.
My question is how can I trigger an event in GWT when a user clicks a link? Do I need to generate GWT controls, and link a click handler? Is it possible to setup an event that fires when the URL is changed???
UPDATE:
Adam answered part of the initial question, but I can't get the querystring after "#". Is there a better way than the function below:
public static String getQueryString()
{
return Window.Location.getQueryString();
}
In other words, if I enter example.com?service=1 I get service=1 as my querystring. If I enter example.com#?service=1, I get a null value for the querystring..
Use History.addValueChangeHandler( handler ), and create a handler to catch the URL changes.
There's no need for click handlers etc., any change of the "hash" part in the URL will be sufficient.
EDIT:
See this code example - it will parse URLs of the form http://mydomain/my/path#tok1&tok2&tok3
public void onValueChange(ValueChangeEvent<String> event) {
String hash = event.getValue();
if ( hash.length() == 0 ) {
return;
}
String[] historyTokens = hash.split("&",0);
// do stuff according to tokens
}
(Just responding to your Update)
Have you tried
History.getToken()
to get the value after the "#"?
