How to find out who has published a post using my OG action

Hoping someone can point me in the right direction.

I have an open graph action that has finally been approved and is active on my app now. Is there any way to track who publishes a post using my OG action from within my app?

Here is the code I'm using for my action:

<script type="text/javascript">
  function postEndorse()
  {
      FB.api(
        '/me/namespace:endorse',
        'post',
        { photo: '<?php the_permalink(); ?>' },
        function(response) {
           if (!response || response.error) {
              alert('Error Occurred' + response + " " + response.error);
           } else {
              alert('Thank you!');
           }
        });
  }
  </script>

I am requesting the publish_actions permissions when people log in.

Thanks

Solution

  • The response in your JavaScript code above has the id of the action.

    {
  id: “{action-instance-id}”
}

    You need to store your actions via database or otherwise. Once you have that you can make a call against it

    /action-instance-id?fields=from.fields(id)

    Which will give a response such as 

    {
  "from": {
    "id": "{user-id}"
  }, 
  "id": "{action-instance-id}"
}

    There are many ways to store this data, one way would be AJAX to PHP/MySQL.
    I suggest reading up on it. The following hasn't been tested, just gives an idea of how to send the data across. Think of it as pseudocode

    Add jQuery to the <head> 

    <script src="jquery.js"></script>

    Send the id of the user, like

    <script type="text/javascript">
  function postEndorse()
  {
      FB.api(
        '/me/namespace:endorse',
        'post',
        { photo: '<?php the_permalink(); ?>' },
        function(response) {
           if (!response || response.error) {
              alert('Error Occurred' + response + " " + response.error);
           } else {
              FB.api(
                response.id + "?fields=from.fields(id)",
                 function(resp) {
                     if (!resp || resp.error) {
                        alert('Error Occurred' + resp + " " + resp.error);
                      } else {
                        $.ajax({
                           type: "POST",
                           url: "fbdata.php",
                           data: { id: resp.from.id, actionid: resp.id }
                        }).done(function( msg ) {
                           alert( "Data Saved: " + msg );
                        });
                     }
              });
           }
        });
  }
  </script>

    Then in fbdata.php something like

    <?php

include("database.inc.php");
mysql_connect($server,$username,$password);
@mysql_select_db($database) or die( "Unable to select database"); 

$id = mysql_real_escape_string($_POST['id']);
$actionid = mysql_real_escape_string($_POST['actionid']);

$database_entry = "INSERT INTO Actions (Id, Action) VALUES ('$id', '$actionid') ;
mysql_query($database_ntry) or die(mysql_error());


mysql_close();
?>
