PHP - Facebook Like Button

I am trying to allow a user to proceed to another page but only after a user has clicked a Facebook like button and a check has been done to check if the currently logged in user has liked the specific Facebook Page.

How can I go about this?

Thanks in advance

Hi Guys,

I am using the PHP Facebook code with my app;

<?php    $app_id = "";   $app_secret = "";   $my_url = "";   session_start();   $code = $_REQUEST["code"];   if(empty($code)) {     $_SESSION['state'] = md5(uniqid(rand(), TRUE)); //CSRF protection     $dialog_url = "https://www.facebook.com/dialog/oauth?client_id="        . $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="       . $_SESSION['state'];     echo("<script> top.location.href='" . $dialog_url . "'</script>");   }   if($_REQUEST['state'] == $_SESSION['state']) {     $token_url = "https://graph.facebook.com/oauth/access_token?"       . "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url)       . "&client_secret=" . $app_secret . "&code=" . $code;     $response = @file_get_contents($token_url);     $params = "user_questions";     parse_str($response, $params);     $graph_url = "https://graph.facebook.com/me?access_token="        . $params['access_token'];     $user = json_decode(file_get_contents($graph_url));     echo("Hello " . $user->name);   }   else {     echo("The state does not match. You may be a victim of CSRF.");   } ?>()

However I am having issues with the permissions, I can only ever get it to ask for "Yout basic info" when it needs to ask for more than that.

Any ideas why?

Cheers in advance.

On Facebook, when you click on "view friends" on one of your friends' profile, a window pops up. Is that made with PHP? Or is it flash or something? In case it's PHP, what would you use to make something like that? Thank you in advance!

Following is the code that works fine if I am passing `/pageid/feed` to `facebook->api`, but when I change it to upload the image directly to my Facebook FAN PAGE photo album, it will not work. Kindly let me know what I am doing wrong in the following code:

    // Works fine
    $status = $facebook->api("/406221796071956/feed", 'post', $attachment);

    // Does not work
    $status = $facebook->api('/196878530339618/photos', 'post', $attachment);

Hi there!

First, i must say that i have no php knowledge, maybe a 1%

Here is what i want to do:

I have wordpress, with a plugin called Facebook connect, it has a cool feature where you can invite your facebook friends, it looks like this:

http://dailyerz.com/login/?fbconnect_action=invite

And i am also using cubepoints, a plugin that rewards users with points. I want to reward users for every user they invite.

From the cube points docs http://techcube.net/docs/1.3/docs.html
i got this:

Quote

The following code will add 10 points to the current logged in user. If no user is logged in, no points will be added. You may input negative number to subtract points.


<php
  if( function_exists('cp_alterPoints') && is_user_logged_in() ){
    cp_alterPoints(cp_currentUser(), 10);
  }
?>

and the invite.php of facebook connect looks like this:

<?php get_header(); 
$fb_user = fb_get_loggedin_user();
?>
<div style="padding:20px;" >
<?php if(FBCONNECT_CANVAS=="web") : ?>
  <fb:serverfbml style="width: 100%;">
    <script type="text/fbml">
      <fb:fbml>
<?php endif; ?>       
      
          <fb:request-form
                    action="<?php echo get_option('siteurl'); ?>"
                    method="GET"
                    invite="true"
                    type="<?php echo get_option('blogname');?>"
                    content="<?php echo get_option('blogname')." : ".get_option('blogdescription'); ?>
                 <fb:req-choice url='<?php echo get_option('siteurl'); ?>'
                       label='<?php _e('Become a Member!', 'fbconnect') ?>' />
              "
              >
 
                    <fb:multi-friend-selector
rows="5"
email_invite="false"
cols="3"
                    showborder="false"
                    actiontext="<?php _e('Invite your friends to Dailyerz.', 'fbconnect') ?>">
        </fb:request-form>
<?php if(FBCONNECT_CANVAS=="web") : ?>
      </fb:fbml>
 
    </script>
  </fb:serverfbml>
<?php endif; ?>
</div>
<?php get_footer(); ?>


Any idea on how to make this work? Do i have to create a Facebook App? 

Thanks!

I dont no if this should even go here but here it goes. I created a blog were each blog post is veiwed on the same page in regards to the id passed to it (as standard). What i really need to do is incorporate the facebook comment box onto the page but... it only relates to the document itself rather than it's dynamic content.

Hey guys,

Been trying to get my head around curl over the past month, I need help with loading one of Facebook's Applications.

I need the script to:
1) Log into Facebook.
2) Load up the application.
3) Load up the application's iFrame.

I've got steps 1 + 2 down, so it logs into Facebook and loads up the application alright, but when it comes to loading up the specific application's iframe, it re-directs me to log in again. I am 99% sure it's something to do with cookies because if you log in locally and load up the iframe url it has no problem loading up the app.

(Iframe URL: http://mobsters-fb-apache-dynamic-lb.playdom.com/prod_facebook/facebook/mobsters_v1/facebook_iframe.php?track=bookmark)


Here is my current code: (Running it in apache)
And also I am really new to curl and am pretty much learning on the go so please excuse any obvious errors

So yeah I need some help in loading up the iframe since that is where I need to grab important data.

Any help would be much appreciated, and yes, I've been to http://php.net/manual/en/book.curl.php a billion times which is why I've come here where the pro's are for help

Thanks.

Hi,

Is anyone here familiar with the Facebook API?

My boss wants people to be able to share their store with their friends on Facebook from within the stores admin panel. He wants the following.

1) Display all friends with a checkbox next to each name.
2) Check the friends you want to inform about your store.
3) Post a message on checked friends wall.

It sounds simple.

The problem is the friends selection screen. Some of my friends on Facebook have 1000 friends. Obviously listing all of them is inpractical. Ideally I need a search box to limit the friends that display and make it easy to find who you are looking for. Does something like this already exist? Does it have a name?

Hi,
I'm having problems with my phpbb forum/facebook coding. I have recently put Facebook Share links in my forum...

The facebook 'Share' links(buttons), are attached to every post viewable within th eforum, and link to:
http://www.facebook.com/sharer.php?u=http://www.mywebsite.com/facebook/share-fb.php?postNo=" . $postrow[$i]['post_id'].'&title='.$userdata['username'].'%20on%20facebook!!'
--> where
'$userdata['username']' username of forum user
..and
'$postrow[$i]['post_id']' = the id of the forum post, to be processed by share-fb.php


So as according to he
http://developers.facebook.com/docs/share
under the Basics section, I will be able to control the thumbnail, title and content from
Quote

You can control the exact title, description, and thumbnail that Facebook Share uses by adding the following meta tags to the <head> element in your page:

So the url looks like this:
http://www.anclchess.net/facebook/share.php?postNo=65914&title=My%20Names%20on%20facebook!!Title%20of%20post

There are 2 major problems.
1) I am passing the post number identity via URL.. which means anyone wanting to view posts they may not have permissions to view, would simply need to change the share.php?postNo=65914&title= and they would have access..
and
2) The the thumbnail, title and content don't seem to work.. I cant figure out why.. see below
This is 'share-fb.php':
<?php

I'm trying to add Facebook connect to my new app, but I'm not sure where to really start.  I looked through a lot of the facebook documentation, but I haven't been able to find any really good implementation suggestions.  I just want basic functionality.

I am going to use this script http://www.gayadesign.com/diy/snotify-easy-notifications-in-jquery/ but I wanted to know how exactly would I make it work like facebook does? What steps would I take to show the other user the notification rather than showing me, the sender it?

Hi all,

I am a beginner for PHP.  I created a site & now I want to add a wall post to my Facebook Page.  This post should be posted via PHP when I add a post to my site, without manually adding that on Facebook Page.   I referred Facebook Developer documentations, but those are really mess for me.    I really don't want this to do with php-sdk or any other.    I want to do this manually.   

Thanks
