facebook - how to post a photo to a fan page using graph api? -


i post photo fan page (as normal timeline status feed) able manage.

my app got following permissions:

email,publish_actions,read_stream,manage_pages

it works own timeline. able post photo on page´s timeline. why not app?

i figered out, permission photo_upload not take effect. maybe facebook has removed it.

my app uses facebook php-sdk.

if try upload photo fan page returns me exception:

 fatal error: uncaught oauthexception: (#200) subject not have permission post photos on page thrown

here how access token fan page:

public function getpagedata()     {         $arrs = $this->facebook->api('/me/accounts');          $pagedata = new cfacebookclientpagedata();         foreach ($arrs['data'] $dataset)         {             if (array_key_exists('name', $dataset) && preg_match('/any\s*fan\s*page/i', $dataset['name']))             {                 $pagedata->scategory = $dataset['category'];                 $pagedata->sname = $dataset['name'];                 $pagedata->saccesstoken = $dataset['access_token'];                 $pagedata->arpermissions = $dataset['perms'];                 $pagedata->ipageid = $dataset['id'];             }         }          return $pagedata;     }

and here how try post it:

public function uploadphoto(cfacebookclientpagedata $user, cfacebookphotodata $photo) {     return $this->facebook->api('/' . $user->ipageid . '/photos',                                 'post',                                 array(                                       'source' => '@' . realpath($photo->slocalpath),                                       'message' => $photo->smessage,                                       'access_token' => $this->saccesstoken                                       )                                 ); }

in other file call this:

$fb = new cfacebookclient($sappid, $ssecret); $fb->init(); $fb->setfileupload(true); $fb->init();  $user = $fb->getpagedata(); $fb->setaccesstoken($user->saccesstoken); $photo = new cfacebookphotodata(); $photo->slocalpath = 'e:\php\www\logo.png'; $photo->smimetype = 'image/png'; $photo->smessage = utf8_encode('posted fresh app :-)'); var_dump($fb->uploadphoto($user, $photo));

edit: solved mentioned in comment below: fixed in snippet not in code.

i guess you're not using page access token can receive app page via 

/me/accounts

the docs @ https://developers.facebook.com/docs/graph-api/reference/page/feed/#publish state that

  • a user access token publish_actions permission can used publish new posts on behalf of person.
  • a page access token publish_actions permission can used publish new posts on behalf of page.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
