How to post on user's wall in facebook after getting permission from user?

I've code to help you to post status with an image to an user's timeline.

After user has given permission to your app , you might have received a query string parameter called 'code' , using this code , we can post to user's timeline.

$code = @$_REQUEST["code"];

      if(!empty($code))
      {
          // Start : Get live user access token ------------------------------------------ //
          $token_url= "https://graph.facebook.com/oauth/"
          . "access_token?"
          . "client_id=" .  FACEBOOK_APP_ID
          . "&redirect_uri=" . urlencode( FACEBOOK_POST_LOGIN_URL)
          . "&client_secret=" . FACEBOOK_APP_SECRECT
          . "&code=" . $code;

          $token = $this->get_app_access_token(FACEBOOK_APP_ID,FACEBOOK_APP_SECRECT,$token_url);
          $access_token = $token;

          // End : Get live user access token ------------------------------------------- //

          // Start : Create album ------------------------------------------------------ //

          $graph_url = "https://graph.facebook.com/me/albums?"
          . "access_token=". $access_token;

          $uri = 'https://graph.facebook.com/albums?access_token='.$access_token;

          $post_fields = array('name' => trim( FACEBOOK_ALBUM_NAME ));

          $curl = curl_init( $uri );
          curl_setopt( $curl, CURLOPT_RETURNTRANSFER, 1 );
          curl_setopt( $curl, CURLOPT_POST, TRUE );
          curl_setopt( $curl, CURLOPT_POSTFIELDS, $post_fields );

          $raw_data = curl_exec($curl);
          curl_close( $curl );

          $created_album_id = json_decode( $raw_data, $assoc = TRUE );

          // End : Create album ---------------------------------------------------------- //   

          $facebook_share_image_url = FACEBOOK_SHARE_IMAGE_PATH;

          $facebook_status_text = 'The status text';

          $graph_url= "https://graph.facebook.com/me/photos";

          $postData = "url=" . urlencode($facebook_share_image_url)
          . "&message=" . urlencode($facebook_status_text)
          . "&access_token=" .$access_token;

          $ch = curl_init();
          curl_setopt($ch, CURLOPT_URL, $graph_url);
          curl_setopt($ch, CURLOPT_HEADER, 0);
          curl_setopt($ch, CURLOPT_POST, 1);
          curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
          curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
          curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
          $output = curl_exec($ch);
          curl_close($ch);

          // End : Add photos ------------------------------------------------------------- //
    }

and the function to get app access token

function get_app_access_token($app_id, $secret,$token_url)
{
    $url = 'https://graph.facebook.com/oauth/access_token';
    $token_params = array(
            "type" => "client_cred",
            "client_id" => FACEBOOK_APP_ID,
            "redirect_uri" => urlencode(FACEBOOK_POST_LOGIN_URL),
            "client_secret" => FACEBOOK_APP_SECRECT
    );

    $a1 = $this->file_get_contents_curl($token_params,$token_url);
    $a2 =  str_replace("access_token=","",$a1);
    $a3 = explode("&expires",$a2);

    return $a3[0];
}

The other function access graph url

function file_get_contents_curl($params,$url)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
    curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE);
    $headers = array(
            "Cache-Control: no-cache",
    );
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    $ret = curl_exec($ch);
    curl_close($ch);
    return $ret;
}

Hope it helps..!!

Posting to facebook page wall via curl

To be able to post content you must grant publish_stream permission to your application.

Requesting permissions can be done using OAuth Dialog.

BTW, If you just need it for user for testing purposes you may use Explorer Tool by choosing your application, clicking Get Access Token and checking needed permissions.

Update:
You will not be able to post on behalf of app, only user or page with appropriate access_token (for page it will require manage_pages and access_token from accounts connection of user).
No need to specify perms in access_token retrieval URL. Permissions should be granted before that step.

PHP cURL : Post to Facebook Page as Page

If it gets posted as yourself, you are not using a Page Token. Debug your Token and see if the Page ID is listed - that´s how you know it´s a Page Token: https://developers.facebook.com/tools/debug/

Btw, you should use the new publish_pages permission to post to Pages: https://developers.facebook.com/docs/apps/changelog#v2_3_changes
