How to implement the new invisible reCAPTCHA on form? - silverstripe

I am trying to get the new "invisible" version of the google reCAPTCHA working on my form.
I am using the https://github.com/UndefinedOffset/silverstripe-nocaptcha
According to the docs, you should just be able to do change this in the config.yml and I assume it would be invisible?
default_size: "invisible"
--
public function HelloForm() {
$fields = new FieldList(
new TextField('Name'),
new EmailField('Email'),
new TextareaField('Message')
);
$actions = new FieldList(
new FormAction('doSubmitHelloForm', 'Submit')
);
$form = new Form($this, 'HelloForm', $fields, $actions);
$form->enableSpamProtection()
->fields()->fieldByName('Captcha')
->setTitle("Spam protection")
->setDescription("Please tick the box to prove you're a human and help us stop spam.");
return $form;
}
config.yml
NocaptchaField:
site_key: "MYKEYINHERE" #Your site key (required)
secret_key: "MYKEYINHERE" #Your secret key (required)
verify_ssl: true #Allows you to disable php-curl's SSL peer verification by setting this to false (optional, defaults to true)
default_theme: "light" #Default theme color (optional, light or dark, defaults to light)
default_type: "image" #Default captcha type (optional, image or audio, defaults to image)
default_size: "invisible" #Default size (optional, normal, compact or invisible, defaults to normal)
proxy_server: "" #Your proxy server address (optional)
proxy_auth: "" #Your proxy server authentication information (optional)
However the captcha is still showing, am I missing something? (Please note I am just testing this on my local dev machine atm).

Ok so there were 2 issues here.
I was using an older version of the nocaptcha module initially. I then upgraded to 0.3.0 (Latest release at the time of posting this) and the captcha was hidden as we wanted.
There was a bug in the module that meant it kept showing an error message when form was submitted (Saying the captcha needed to be ticked). The author has now fixed this and will be tagging this release soon as 0.4.0.

Wordpress get user info from same browser logged into site

I'm trying to use the Wordpress API wp_get_current_user(), however it's always returning the 0 user, with empty data. I am on a fresh install of Wordpress and I have just created my own theme and added an API hook.
I see lots of guides/info on grabbing data using Nonce from a separate client/computer, but I'm just trying to get the $user from the same browser that should be already logged in via the wordpress admin interface. I've verified that my browser has cookies set. My understanding of verification is that wp_get_current_user() should be able to use these cookies to verify my user and return data. .
Just to show I am logged into wordpress
This is my functions.php
located under wp-content/themes/myapi/functions/
add_action('rest_api_init', function () {
register_rest_route( 'api', 'test',array(
'methods' => 'GET',
'callback' => 'logged_in_wp',
));
});
function logged_in_wp($request){
if ( is_user_logged_in() ) {
return new WP_Error( 'me', 'me', array( 'status' => 200 ) );
}
return new WP_Error( 'not-logged in WP', 'not-logged in WP', array( 'status' => 400 ) );
}
?>
I'm using the following URL to access the data
http://localhost:8080/?rest_route=/api/test
I'm expecting it to return a me,me,200, instead, i'm only seeing the not-logged-in 400 error.
so what is the difference between localhost:8080 and localhost:8080?rest_route=/api/test that wordpress cannot figure out that I am logged in?
So, I'm guessing since nobody is answering and based on the readings I've done. What I'm asking for is impossible. It seems it is a security response by wordpress. You will need to authenticate even if the user is logged into Wordpress on the same domain/browser.
What do you use to test your request?
Using postman, you can insert useful parameters which will help you on authentication. Hence if you want to logged in using the WordPress Rest api, you must insert information of the current user properly in the section Authorization (Chose basic authentication and inside, fill the username and the password of an existing account (in this case Admin) and try it again.
Here is what i did for an exemple:
Sample image for the authorization which will soon help to know about the current user login
next using
$user_id = username_exists($username);
$user = get_user_meta($user_id);
$response['code'] = 200;
using "get_user_meta(wp_get_current_user()->ID, 'nickname', true);"
you can now determine the current user been logged.
Here in this sample if you make good use of the above information, you can create a good function "logged_in_wp()".
Here is my result on postman
I hope this will help you by the way

Why is the Symfony Mailer Component returning an empty response?

I want to convert my mailing from Swift Mailer to the Mailer Component, since I upgraded to Symfony 4.3.
I've translated my MAILER_URL to a MAILER_DSN, the following way:
MAILER_URL=smtp://smtp.zoho.eu:465?encryption=ssl&auth_mode=login&username=bar#foo.com&password=password123
MAILER_DSN=smtp://bar#foo.com:password123#smtp.zoho.eu:465/?encryption=ssl&auth_mode=login
As you can see, I'm using Zoho as my mail provider.
However, I'm getting the following internal server error:
Expected response code "250" but got an empty response.
I've tried switching from SSL to TLS, with no (different) result.
The code I've written to send my test mail, is as follows:
$email = (new TemplatedEmail())
->from('bar#foo.com')
->to('foo#bar.com')
->subject('Test')
->htmlTemplate('email.html.twig')
->context([
'expiration_date' => new \DateTime('+7 days'),
'username' => 'foo',
])
;
$this->mailer->send($email);
I expect my code to send a mail to "foo#bar.com", but instead it turns the empty response as described.
The problem is the the "#" in the username must be encoded:
MAILER_DSN=smtp://bar%40foo.com:password123#smtp.zoho.eu:465/?encryption=ssl&auth_mode=login

How can I use a different login/signup mechanism for wordpress

I have so far integrated a multisite wordpress that uses 4 main subdomain templates in a single wordpress installation: college.mysite.com | jobs.mysite.com | advisors.mysite.com | answers.mysite.com
A wp user is only required to login once and they inmediately have acccess to any wp template.
However, What I would like to achieve is a bit more complicated than that. I don't want new users and existing members to use wordpress as their main user interface to access private content.
In fact I have disabled registration and hidden wp login altogether.
I would like a more secure and less public signup/login.
For this occassion I would like wordpress to ignore the default login credentials and use instead custom db table names and hashmethod pulled from the same wordpress database.
For instance I have a yii platform called: humhub.
For a user to use wordpress they would need to login through humhub and have wp read the db table names:
user instead of wp_users
a secondary db name would need to be read for the password because humhub uses:
user_password instead of the default value within wp_users (user_pass)
I've tried integrating yii framework with wordpress, I've tried tweaking here and about within the yii framework so that it reads two databases separately but it's far more complicated than simply redirecting the wp login credentials by changing the default login table names within the wordpress files,
please help me,
Let's assume you have some unique identifier so that one user will not accidentally collide with another (in YII/HumHub)
You can load up the WordPress API via
require_once("/path/to/wp-load.php");
//Found normally in the WordPress root directory alongside wp-config.php
You can then when creating a new user in HumHub do:
wp_create_user( $username, $password, $email );
//Where username is the unique identifier
//password is ideally a random hash
//email is their email if relevant
And then log them in (assuming you remembered the username and password!!)
$creds = array();
$creds['user_login'] = $username;
$creds['user_password'] = $password;
$creds['remember'] = true;
$user = wp_signon( $creds, false );
if ( !is_wp_error($user) ) {
ob_start(); //flush buffers - otherwise login won't work or user gets redirected to dashboard
$user_id = $user->ID;
wp_set_current_user( $user_id, null );
wp_set_auth_cookie( $user_id,true );
do_action( 'wp_login', $username );
ob_end_clean();
} else {
//Handle the login error
}
They are then logged into WordPress with cookies etc without any headers interfering with HumHub
Note - the above method may not work is there is a name conflict between WordPress and YII/HumHub. You will get a php error with details of the conflict if that is the case and will have to try something else (such as Oauth plugin)

Loading Google Maps API with wp_enqueue_script

I'm trying to load the Google Maps API using the following syntax:
add_action('admin_enqueue_scripts', 'load_google_maps');
...
function load_google_maps()
{
// The actual API key is configured in an options page
$key = get_option('google_maps_api_key');
$gmaps_url = 'http://maps.googleapis.com/maps/api/js?key=' . $key . '&sensor=false';
wp_enqueue_script('google-maps', $gmaps_url, NULL, NULL);
}
WordPress is escaping the "&" to "&#038". This actually makes the Google server reject the request. When I type it directly into browser address bar with "&sensor=false" at the end, it loads fine.
I saw a bug of this kind mentioned in the WordPress trac system: http://core.trac.wordpress.org/ticket/9243 but it was dismissed as invalid, and the admin responding to the request showed somehow that the "&#038" approach was fine. It is definitely not fine from Google's point of view.
I could of course just get the function to echo the HTML as a script tag, but I'd rather use the wp_enqueue_script system if possible.
Anyone know of a solution to this?
Cheers,
raff
I've got something similar in our code, and it's working fine (even encoded as &#038). I suspect your problem is that it's being double-encoded, as you already have &. Trying changing it to:
$gmaps_url = 'http://maps.googleapis.com/maps/api/js?key=' . $key . '&sensor=false';
For what it's worth, our (working) code is:
wp_register_script('googlemaps', 'http://maps.googleapis.com/maps/api/js?' . $locale . '&key=' . GOOGLE_MAPS_V3_API_KEY . '&sensor=false', false, '3');
wp_enqueue_script('googlemaps');
($locale in this case is set to hl=en)
Edit
Looks like the behaviour's changed in the latest version of WordPress - the above doesn't work (but I'll leave it for people on legacy versions). The only alternative I can see to echoing the script is to add a clean_url filter, something like this:
add_filter('clean_url', 'so_handle_038', 99, 3);
function so_handle_038($url, $original_url, $_context) {
if (strstr($url, "googleapis.com") !== false) {
$url = str_replace("&", "&", $url); // or $url = $original_url
}
return $url;
}
Pretty ugly, but perhaps marginally better than echoing the script, as it'll still use the WordPress dependency management.

PHP SDK: How do I capture the access token after user auths app?

This is for a canvas app on the Facebook Platform using the new(est) Facebook PHP SDK.
We are using the PHP example from the Facebook tutorial (https://developers.facebook.com/docs/appsonfacebook/tutorial/) to trigger the OAuth dialog and get the test user to the redirect URL.
At the redirect URL, we use the PHP example from the Facebook signed request docs page (https://developers.facebook.com/docs/authentication/signed_request/) and our test users can successfully authorize the app.
However, after the test user auths the app, we are not able to capture the access token and its expiration. We can see it in the address bar appended to the redirect URL, but it does not show up in the $_REQUEST array. If we add {$access_token = $facebook->getAccessToken();} to the redirect URL page, it shows a value for the access token, but the value it shows is not the full token string that we see when we click on Show Token in the Test User Roles page (which we believe is the correct access token for the test user).
Here is an example of the redirect URL with an access token appended:
http://karmakorn.com/karmakorn/alpha20/kk-fb-auth.php#access_token=126736467765%7C2.AQDavId8oL80P5t9.3600.1315522800.1-100002908746828%7CJICJwM1P_97tKmqkEO5pXDCf-7Y&expires_in=6008
Here is what var_dump shows for the $REQUEST array for that same page:
array(3) { ["_qca"]=> string(26) "P0-709927483-1291994912966" ["__switchTo5x"]=> string(2) "30" ["PHPSESSID"]=> string(26) "euois02ead39ijumca7nffblh2" }
We have no idea why the $_REQUEST array varies from the values appended to the URL, and more importantly -- how to capture the access token and its expiration date.
Can someone show us a working example of how they capture this data after running the parse_signed_request($signed_request, $secret) function on the redirect page? Thanks!
ADDITIONAL INFO:
Here is the pertinent code from A) our test index page, and B) our test redirect page. If we use our text index page as the redirect url it gets stuck in an endless loop -- because the user is never identified.
A) Index Page
// Create kk-fb app instance
$facebook = new Facebook(array(
'appId' => KKFB_ID,
'secret' => KKFB_KY,
'oauth' => true,
));
$app_id = KKFB_ID;
$secret = KKFB_KY;
$canvas_auth = 'http://karmakorn.com/karmakorn/alpha20/kk-fb-auth.php';
$auth_url = "https://www.facebook.com/dialog/oauth?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode($canvas_auth)
. "&response_type=token"
. "&scope=email,publish_stream";
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
if (empty($data["user_id"])) {
echo("<script> top.location.href='" . $auth_url . "'</script>");
} else {
echo ("Welcome User: " . $data["user_id"]);
}
B) Redirect Page
// Create kk-fb app instance
$facebook = new Facebook(array(
'appId' => KKFB_ID,
'secret' => KKFB_KY,
'oauth' => true,
));
$app_id = KKFB_ID;
$secret = KKFB_KY;
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
$user = $facebook->getUser();
$access_token = $facebook->getAccessToken();
echo "User: $user <br>";
echo "Access Token: $access_token <br>";
echo "Signed Request: $signed_request <br>";
var_dump($_REQUEST);
Here is what shows up as these echo results:
User: 0
Access Token: 126736467765|**SECRET**
Signed Request:
array(3) { ["_qca"]=> string(26) "P0-709927483-1291994912966" ["_switchTo5x"]=> string(2) "30" ["PHPSESSID"]=> string(26) "frugi545cdl15gjind1fnv6pq1" }
Interestingly, when the test user goes back to the index page the if condition is satisfied and we can get the correct access token:
Welcome User: 100002908746828
Access Token: 126736467765|2.AQBgcyzfu75IMCjw.3600.1315544400.1-100002908746828|m5IYEm976tJAkbTLdxHAhhgKmz8
Obviously, we are still missing something!? Also, we need to learn how to get the expiration time as a variable too so we can store both of these in our database.
OK, let's try this again.
Server-side vs Client-side Authentication
You are exclusively using the PHP SDK, so you want to do server-side authentication, where the authentication code is sent to the server over HTTP via the URL. This will allow you to fetch an access token for the user on the first page load after auth (in your case, the redirect page). The auth_url you are currently constructing is setting response_type=token, which forces the redirect to use client-side auth mode and set the token in the URL fragment instead of in the query. You should remove that parameter completely. In fact, I highly recommend you just use the PHP SDK instead of constructing that URL yourself. See example below.
Application Access Tokens
The odd-looking access token 126736467765|SECRET is your application access token, which is composed of your app ID and secret key. The application access token is returned by getAccessToken() if no user access token is available (because some API calls require at least some sort of access token). This also means that you've revealed your secret key to the world via this blog post, so you should reset your app secret otherwise anyone will be able to make API calls on your behalf. I highly recommend you elide parts of your access tokens if you share them with others.
Token Expiration
The OAuth 2.0 flow and v3.1.1 of the PHP SDK don't make determining the expiration time of a token all that easy. I would suggest attempting to make the API call, and then refreshing the token if the API call fails with an OAuthException. Tokens can be invalid even if they haven't expired, so this deals with more cases. However, if you still want to maintain the expiration date on your end, you might just want to extract it from the token itself. If you have an expiring token, then the expiration timestamp will be contained within that string. Here's a function I put together quickly to extract that:
function extractExpirationFromToken($access_token) {
$segments = explode('|', $access_token);
if(count($segments) < 2) { return 0; }
$segments = explode('.', $segments[1]);
if(count($segments) < 4) { return 0; }
$expires = $segments[3];
$dash_pos = strrpos($expires, '-');
if($dash_pos !== false) {
$expires = substr($expires, 0, $dash_pos);
}
return $expires;
}
New Index Page Code
// Create kk-fb app instance
$facebook = new Facebook(array(
'appId' => KKFB_ID,
'secret' => KKFB_KY,
));
$canvas_auth = 'http://karmakorn.com/karmakorn/alpha20/kk-fb-auth.php';
$auth_url = $facebook->getLoginUrl(array(
'scope' => 'email,publish_stream',
'redirect_uri' => $canvas_auth, // you could just redirect back to this index page though
));
$user = $facebook->getUser();
if (empty($user)) {
echo("<script> top.location.href='" . $auth_url . "'</script>");
} else {
echo ("Welcome User: " . $user);
}
Redirect Page
I don't think you need this page at all. You could just redirect the user back to your original index page.
// Create kk-fb app instance
$facebook = new Facebook(array(
'appId' => KKFB_ID,
'secret' => KKFB_KY,
));
$user = $facebook->getUser();
$access_token = $facebook->getAccessToken();
// also copy the function definition given earlier
$expiration = extractExpirationFromToken($access_token);
echo "User: $user <br>";
echo "Access Token: $access_token <br>";
echo "Expiration: $expiration <br>";
echo "Request: <br>";
var_dump($_REQUEST);
You can use the facebook build in method getAccessToken() for example;
$access_token = $facebook->getAccessToken();
This will give you the access token to your variable, now if you are getting it empty, remember to first check if the fuid is being properly catch, if it isn't you might need to review your settings be sure your "App Domain" is set this part is very important after setting it correctly you need to reset your app secret, then set your new values in your auth code. Hope this help, let me know :)
pd. Also remember to keep the scope of your variables visible in your whole php file or class.
Problem
The access_token in your pasted URL is not part of the query string, but instead contained in the URL fragment (after the #). URL fragments are not sent to the web server, and are readable only by client-side code like Javascript. Therefore the PHP SDK only sees http://karmakorn.com/karmakorn/alpha20/kk-fb-auth.php, which is why $_REQUEST does not contain an access_token key.
Questions / Notes
What are you using for your redirect_uri? I think you want to be using something like http://apps.facebook.com/your_canvas_url/
You shouldn't need to call parse_signed_request yourself or copy any code from the signed request page. The PHP SDK will do that for you. Just call:
$facebook = new Facebook(array(
'appId' => '…',
'secret' => '…',
));
$access_token = $facebook->getAccessToken();
Possible solutions
Also use the Facebook Javascript SDK. You can start by adding its <script> tag in your destination page (kk-fb-auth.php) (see the docs for full details; don't forget to set oauth: true). The JS SDK should set a cookie (named fbsr_126736467765) which the PHP SDK will be able to read via $_REQUEST or $_COOKIE on subsequent page loads.
If you want to do this with PHP, you can get the user's access token with a separate call to the Graph API at your redirect_uri. For this you need to change the response_type of your $auth_url in your index page to "code" or "code token".
Then, at your redirect page, Facebook will add a "code" parameter in the querystring. This API call will return you the full access_token and expiration time:
https://graph.facebook.com/oauth/access_token?
client_id=YOUR_APP_ID&
redirect_uri=YOUR_URL&
client_secret=YOUR_APP_SECRET&
code=$_REQUEST['code']
For more information you can refer to the docs on authentication.
