Say I want to allow users to chat with each other either through text or video on my site, what would be the best way to go on about doing that? I know basic text chat system can be created with PHP/Mysql/Ajax. What about video chat? Or is there a chat plugin/service out there that I can use to implement in my site? Note that I am looking for something can allow thousands of registered users to chat with each other at the same time.

Hello everyone.. I have a question to delete comment based from user-id itself. I use PHP SDK to delete any comment to my facebook page and it was success as long as I specify the comment-id.. Below are my codes to delete a comment from comment-id $request = new FacebookRequest( $session, 'DELETE', '/{comment-id}' ); $response = $request->execute(); $graphObject = $response->getGraphObject(); Is it possible to delete comment based on user-id itself? I know that I just need to query the graph api to get the comment-id from A but each comment have different id`s so its hard to query the comment-id everytime.. For example: A, B, and C comment to my facebook post and I want to delete the comment where the user-id is from A? So, if the api scan and found out that A is commenting to my post, it will be deleted instead deleting B and C I really appreciate for any help from you guys.. Thanks

Hi, Apologies if this isn't the right forum for this question. I couldn't find the perfect forum for my question, but I'm hoping someone can help. Basically, I've been having problems with a site I manage, with the site going down regularly, 401 Forbidden error pages cropping up reguarly, as well as Server Configuration Error pages, although only ever sporadically. I've been trying everything to work out the issue but no luck as of yet. However, one thing that seems strange is the following messages that I'm getting in the access logs. Now, this shouldn't be a problem as Facebook often creates messages like these when it's accessing files from a server. However, there are thousands of messages like this that reference files that don't exist. Honestly, it's constantly trying to access .jpg files that don't exist, and so I suspect this is what's causing the server to keep crashing. Has anyone had anything similar to this before? comono.co.uk 173.252.88.88 - - [20/Nov/2015:13:13:46 +0000] "GET /uploads/2009/9/28/873128bf77.jpg HTTP/1.1" 403 379 "-" "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)" Thanks, Russ

Hi I'm having some issues working with the facebook sdk5 so im wondering if anyone has had the same issues, i've looked on google and can only see some issues when used with a framework like codeigniter When I run my login.php script it shows the facebook login button and sucessfully redirects me to the callback page, and shows some metadata, but following that comes some errors Notice: Undefined variable: config in C:\www\fb\fb-callback.php on line 52 Fatal error: Uncaught exception 'Facebook\Exceptions\FacebookSDKException' with message 'Access token metadata contains unexpected app ID.' in C:\www\fb\facebook-php-sdk-v4-5.0.0\src\Facebook\Authentication\AccessTokenMetadata.php on line 329 Facebook\Exceptions\FacebookSDKException: Access token metadata contains unexpected app ID. in C:\www\fb\facebook-php-sdk-v4-5.0.0\src\Facebook\Authentication\AccessTokenMetadata.php on line 329 oddly these errors show despite me taking the code directly from the facebook developers area, and the only things i've added to their code sample is the top 2 lines session_start(); require_once ('facebook-php-sdk-v4-5.0.0/src/Facebook/autoload.php'); my scripts are login.php <?php session_start(); require_once ('facebook-php-sdk-v4-5.0.0/src/Facebook/autoload.php'); $fb = new Facebook\Facebook([ 'app_id' => '', 'app_secret' => '', 'default_graph_version' => 'v2.4', ]); $helper = $fb->getRedirectLoginHelper(); $permissions = ['email']; // Optional permissions $loginUrl = $helper->getLoginUrl('http://192.168.0.4/fb/fb-callback.php', $permissions); echo '<a href="' . htmlspecialchars($loginUrl) .

I'm looking for an application or a social wall plugin to be added to a project. After looking at Wordpress and finally sifting through all the plugins (maybe all), I have come to a conclusion the plugins are not giving me enough customization options. For example, customizing the registration form. I need to add javascript for a combo box in order to display different options depending on what was selected. What I need - Your Opinion on a good social wall that's easy to make changes. I need a secure login and password --- PDO based A control panel would be nice to activate users or deactivate. A customized registration form Ability to add more pages, add php to customize it to work like I need it to. Responsive. If anyone has an opinion with experience on this matter it would be great to hear from you.
