php - Which facebook API's? -

-

is possible me post message on given users facebook wall, if perform action on website?

basically, looking step step guide achieve this, have not been able figure out how via facebook documentation.

step 1:

set new application @ facebook. enter details website address , domain name. note down api key, application id, , application secret. can set new facebook application here. note: able access facebook developers dashboard need verified developer, i.e. should either have mobile number or credit card verified it.

step 2:

set authentication method check if user logged facebook , if facebook session exists ask basic permissions user. can using php sdk:

$fb_sdk_path = facebook_sdk_path; require_once($fb_sdk_path);  //initialize fb object $facebook = new facebook(array(     'appid'  => fb_app_id,     'secret' => fb_app_secret,     'cookie' => true,     'domain' => 'example.com' ));  //try session. if fails means user not logged facebook $session = $facebook->getsession();  if (!$session) {     //get facebook login url     $url = $facebook->getloginurl(array(         'canvas' => 1,         'fbconnect' => 0          )     );  //put login url script redirect facebook login page (if want this)     echo "<script type='text/javascript'>top.location.href = '$url';</script>";     exit; } else {     //try user details session trigger permissions dialog.     try {         $uid = $facebook->getuser();     } catch (facebookapiexception $e) {     } }

step 3:

use facebook javascript fb.ui method generate post form.

<div id="fb-root"></div> <!-- don't forget include --> <script src="http://connect.facebook.net/en_us/all.js"></script><!-- include fb js --> <script type="text/javascript">      //initialize facebook      fb.init({          appid:'your_app_id',          cookie:true,          status:true,         xfbml:true       });  //call function on click or other event function post_to_profile() {     fb.ui({     method: 'feed',     name: 'title of feed',     link: 'link on title',     caption: 'caption show below link, domain name',     description: 'description',     picture:'picture show',     message: 'default message. can edited user before posting'     }); } </script>

this should enough working.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
