The error I'm getting is:
Curl error: couldn't connect to hostCurl error: couldn't connect to

I have tried almost everything to solve this problem but it doesn't seem to work file_get_contents doesn't work either but its enabled.
$response = curl_exec($ch);
if($response === false) {

I am trying to end up with some descent facebook login on my website, but I came up with a little problem. When i try to login, facebook doesn't even ask for an email permission, only for my location. Here's the main part of my code:
$app_id = "XXXXXX";
$app_secret = "XXXXX";
$my_url = "XXXXXX";
$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']."&scope=publish_stream,user_location,email";
echo("<script> top.location.href='" . $dialog_url . "'</script>");
}
if (!$_POST) {
if($_SESSION['state'] && ($_SESSION['state'] === $_REQUEST['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);
$params = null;
parse_str($response, $params);
$_SESSION['access_token'] = $params['access_token'];
$graph_url = "https://graph.facebook.com/me?access_token="
. $params['access_token'];
$user = json_decode(file_get_contents($graph_url));
} else {
echo("The state does not match. You may be a victim of CSRF.");
}
}
Where's the problem?
i am trying to post image to a facebook fun page, it's working will on my own wall but the fun page not and have no problem with posting text to fb fun page wall.

$code = $_REQUEST["code"];
//Obtain the access_token with publish_stream permission
if (!$code)
{
$dialog_url= "http://www.facebook.com/dialog/oauth?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)

}

. "&method=POST"
. "&access_token=" .$access_token;
echo '<html><body>';
echo file_get_contents($graph_url);
echo '</body></html>';
}
what can i do i think it's about the graph_url
You need to provide the data as encoded binary of the image itself.
The URL parameter only adds a link to the POST as a part of the text or annotation, it will not retrieve and add the photo istelf from that URL!
add something like
...
"url=" . urlencode(file_get_contents($photo_url));
...
And: furthermore the Method must be POST, I'm not quite sure whether "file_get_contents" is going to POST the data and not just doing a GET as the name imposes.
I have seen an example in facebook documentation.
$post_url = "https://graph-video.facebook.com/me/videos?"
. "title=" . $video_title. "&description=" . $video_desc
. "&". $access_token;
But i want to do this in facebook php-sdk.
$facebook->api('/me/videos/');
But it seems the video server is https://graph-video.facebook.com.
So how do i do this in graph api using php-sdk?
through graph its much more simple
To a group you can do this:
<?php
$app_id = "YOUR_APP_ID";
$app_secret = "YOUR_APP_SECRET";
$my_url = "YOUR_POST_LOGIN_URL";
$video_title = "TITLE FOR THE VIDEO";
$video_desc = "DESCRIPTION FOR THE VIDEO";
$group_id = "YOUR_GROUP_ID";
$code = $_REQUEST["code"];
echo '<html><body>';
if(empty($code)) {
$dialog_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&scope=publish_stream";
echo('<script>top.location.href="' . $dialog_url . '";</script>');
}
$token_url = "https://graph.facebook.com/oauth/access_token?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$access_token = file_get_contents($token_url);
$post_url = "https://graph-video.facebook.com/" . $group_id . "/videos?"
. "title=" . $video_title. "&description=" . $video_desc
. "&". $access_token;
echo '<form enctype="multipart/form-data" action=" '.$post_url.' "
method="POST">';
echo 'Please choose a file:';
echo '<input name="file" type="file">';
echo '<input type="submit" value="Upload" />';
echo '</form>';
echo '</body></html>';
?>
to a page you can do this
<?php
$app_id = "YOUR_APP_ID";
$app_secret = "YOUR_APP_SECRET";
$my_url = "YOUR_POST_LOGIN_URL";
$video_title = "TITLE FOR THE VIDEO";
$video_desc = "DESCRIPTION FOR THE VIDEO";
$page_id = "YOUR_PAGE_ID"; // Set this to your APP_ID for Applications
$code = $_REQUEST["code"];
echo '<html><body>';
if(empty($code)) {
// Get permission from the user to publish to their page.
$dialog_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&scope=publish_stream,manage_pages";
echo('<script>top.location.href="' . $dialog_url . '";</script>');
} else {
// Get access token for the user, so we can GET /me/accounts
$token_url = "https://graph.facebook.com/oauth/access_token?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$access_token = file_get_contents($token_url);
$accounts_url = "https://graph.facebook.com/me/accounts?" . $access_token;
$response = file_get_contents($accounts_url);
// Parse the return value and get the array of accounts we have
// access to. This is returned in the data[] array.
$resp_obj = json_decode($response,true);
$accounts = $resp_obj['data'];
// Find the access token for the page to which we want to post the video.
foreach($accounts as $account) {
if($account['id'] == $page_id) {
$access_token = $account['access_token'];
break;
}
}
// Using the page access token from above, create the POST action
// that our form will use to upload the video.
$post_url = "https://graph-video.facebook.com/" . $page_id . "/videos?"
. "title=" . $video_title. "&description=" . $video_desc
. "&access_token=". $access_token;
// Create a simple form
echo '<form enctype="multipart/form-data" action=" '.$post_url.' "
method="POST">';
echo 'Please choose a file:';
echo '<input name="file" type="file">';
echo '<input type="submit" value="Upload" />';
echo '</form>';
}
echo '</body></html>';

I am trying to get Facebook profile picture . I am using the following with my value in place of ######### . After running the PHP i get a message "Hello".
I want that i get my name also with it like "Hellow Aditya" along with my profile picture. what should i edit to get that ? Also would it be possible to save the profile picture on the sever itself?
<?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);
$params = null;
parse_str($response, $params);
$graph_url = "https://graph.facebook.com/me?access_token="
. $params['access_token'];
$user = json_decode(file_get_contents($graph_url));
echo("Hello " . $user->name);
}
else {
echo("The state does not match. You may be a victim of CSRF.");
}
?>
You can get it this way:
http://graph.facebook.com/[USER ID]/picture
A few days ago I suddenly started getting 400 errors in my app. It was completely fine before.
Warning: file_get_contents(https://graph.facebook.com/me/accounts?access_token=XXXXXXXXXXXX) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request
It's really frustrating. I can get the access_token just fine but I can't get "https://graph.facebook.com/me/accounts?access_token=XXXXXXXXXXXX". I know that URL is correct because I can see the content by loading it on the browser.
if(!$code){
$display = 'page';
$scope = 'manage_pages';
$_SESSION['state'] = md5(uniqid(rand(), TRUE)); //CSRF protection
$oauth_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
. $_SESSION['state'];
echo "<script type=\"text/javascript\">\ntop.location.href = \"$oauth_url\";\n</script>";
};
if ($code && $_REQUEST['state'] == $_SESSION['state']){
$token_url = "https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $app_id
. "&client_secret=" . $app_secret . "&code=" . $code . "&redirect_uri=" . $my_url;
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$graph_url = "https://graph.facebook.com/me/accounts?access_token=" . $params['access_token'];
$user = json_decode(file_get_contents($graph_url));
$pages_data = $user->data;
}
Any help will be VERY appreciated!
