Facebook Curl Code?

[mcfmullen]

I'm trying to create a "Post" link that when clicked, will allow the user to post information onto their wall. I have figured out how to enable the proper permissions but the problem is one of two things:

 

My code:

<form method='post' action='https://graph.facebook.com/me/feed'>
<input type='text' name='message' id='message' />
<input type='text' name='access_token' id='access_token'
value='<?php echo $session['access_token'];?>' />
<input type='submit' />
</form>

 

The above DOES post onto my wall on behalf of my website, however, the browser attempts to download the url file for some reason and I get a popup saying "Cannot download file for whatever reason".

 

I've looked at Facebook's Open Graph API and found this:

curl -F 'access_token=...' \
     -F 'message=Check out this funny article' \
     -F 'link=http://www.example.com/article.html' \
     -F 'picture=http://www.example.com/article-thumbnail.jpg' \
     -F 'name=Article Title' \
     -F 'caption=Caption for the link' \
     -F 'description=Longer description of the link' \
     -F 'actions={"name": "View on Zombo", "link": "http://www.zombo.com"}' \
     -F 'privacy={"value": "ALL_FRIENDS"}' \
     -F 'targeting= {"countries":"US","regions":"6,53","locales":"6"}' \
     https://graph.facebook.com/me/feed

 

So my question is: How do I fix my current code to prevent the downloading of the url file OR how do I even use Facebook's code?

 

I've reseacrhed Curl and I don't understand how to translate the code into php (preferably) or javascript.

if you mean to access a PHP session variable, this code is not correct:

 

<?php echo $session['access_token'];?>

 

it should be

 

<?php echo $_SESSION['access_token'];?>

Just search for a cURL post example, very simple...

<?php echo $_SESSION['access_token'];?>

 

It is not a session variable, but simply an array called session. The variable is called according to the Facebook PHP SDK.

The examples I find look nothing like this code. Could you elaborate?

Perfect example here:

Just change the form fields to the ones in your working form (message, token).

Solved!

 

	<?php		 
//extract data from the post
extract($_POST);

//set POST variables 
$url = 'https://graph.facebook.com/me/feed';
$fields = array(
	'access_token'=>urlencode($access_token),
	'message'=>urlencode($message),
	   );
    
//url-ify the data for the POST 
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');

//open connection 
$ch = curl_init();

//set the url, number of POST vars, POST data 
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);

//execute post 
$result = curl_exec($ch);

//close connection
curl_close($ch);
?>

One thing though:

 

How do I stop the code from printing my facebook ID#?

 

Ex: it returns: {"id":"87658973_089756465457845"}

[the182guy]

You must be printing/echoing the $result variable somewhere?

[mcfmullen]

Not at all, the complete page code is above, I haven't removed a thing.

[the182guy]

Try adding this option to the other cURL options

 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

[mcfmullen]

That did the trick!
