Has Facebook sharer php changed to no longer accept detailed parameters

Question

We have been opening a sharing popup  via window open  with the URL like  https   www facebook com sharer sharer php s 100 amp p title  EXAMPLE amp p summary  EXAMPLE amp p url  EXAMPLE amp p images  0  EXAMPLE    and until some unknown point in the last month or so everything was fine   What is happening now is  the popup dialog appears and correctly includes the Title  Description  Image and URL provided by the query string parameters  but when the post is submitted  the resulting wall post on Facebook is missing the Title  Description and Image  though it still links to the correct URL   Does anyone know if there have been recent changes which could have suddenly stopped this from working   Pre-empting some common responses     sharer php URL was deprecated  - usage seemed to continue and it seemed the consensus was that it was largely considered to be sticking around - I haven t seen any specific indication that it should have suddenly ceased working - might have missed something  Use JavaScript SDK these OG meta tags  - not possible in my specific situation - just trust me     I can explain if you REALLY want but it s really not relevant   Use the feed dialog  - not suitable due to lack of support for posting with attachments on FB pages

If you encode the  amp  in your URL to  26 it works correctly  Just tested and verified

Facebook no longer supports custom parameters in sharer php     The sharer will no longer accept custom parameters and facebook will   pull the information that is being displayed in the preview the same   way that it would appear on facebook as a post from the url OG meta   tags    Use dialog feeds instead of sharer php  https   www facebook com dialog feed    app id 145634995501895    amp display popup amp caption An 20example 20caption     amp link https 3A 2F 2Fdevelopers facebook com 2Fdocs 2Fdialogs 2F    amp redirect uri https   developers facebook com tools explorer   Official answer from fb team

Starting from July 18  2017 Facebook has decided to disregard custom parameters set by users  This choice blocks many of the possibilities offered by this answer and it also breaks buttons used on several websites   The quote and hashtag parameters work as of Dec 2018        Does anyone know if there have been recent changes which could have suddenly stopped this from working    The parameters have changed  The currently accepted answer states      Facebook no longer supports custom parameters in sharer php   But this is not entirely correct  Well  maybe they do not support or endorse them  but custom parameters can be used if you know the correct names  These include    URL  of course    u custom image   picture custom title   title custom quote   quote custom description   description caption  aka website name    caption   For instance  you can share this very question with the following URL   https   www facebook com sharer sharer php u http 3A 2F 2Fstackoverflow com 2Fq 2F20956229 2F1101509 amp picture http 3A 2F 2Fwww applezein net 2Fwordpress 2Fwp-content 2Fuploads 2F2015 2F03 2Ffacebook-logo jpg amp title A nice question about Facebook amp quote Does anyone know if there have been recent changes which could have suddenly stopped this from working 3F amp description Apparently 2C the accepted answer is not correct    Try it   I ve built a tool which makes it easier to share URLs on Facebook with custom parameters  You can use it to generate your sharer php link  just press the button and copy the URL from the tab that opens

Your problem is caused by the lack of markers OpenGraph  as you say it is not possible that you implement for some reason    For you  the only solution is to use the PHP Facebook API     First you must create the application in your facebook account   When creating the application you will have two key data for your code    YOUR APP ID  YOUR APP SECRET  Download the Facebook PHP SDK from here  You can start with this code for share content from your site    lt  php      Remember to copy files from the SDK s src  directory to a      directory in your application on the server  such as php-sdk    require once  php-sdk facebook php        config   array       appId    gt   YOUR APP ID        secret    gt   YOUR APP SECRET        allowSignedRequest    gt  false    optional but should be set to false for non-canvas apps          facebook   new Facebook  config      user id    facebook- gt getUser      gt   lt html gt     lt head gt  lt  head gt     lt body gt      lt  php     if  user id              We have a user ID  so probably a logged in user           If not  we ll get an exception  which we handle below        try            ret obj    facebook- gt api   me feed    POST                                       array                                         link    gt   www example com                                          message    gt   Posting with the PHP SDK                                                echo   lt pre gt Post ID       ret obj  id       lt  pre gt                Give the user a logout link          echo   lt br   gt  lt a href       facebook- gt getLogoutUrl        gt logout lt  a gt            catch FacebookApiException  e               If the user is logged out  you can have a             user ID even though the access token is invalid             In this case  we ll get an exception  so we ll            just ask the user to login again here           login url    facebook- gt getLoginUrl  array                          scope    gt   publish stream                                      echo  Please  lt a href       login url      gt login  lt  a gt            error log  e- gt getType             error log  e- gt getMessage                      else             No user  so print a link for the user to login          To post to a user s wall  we need publish stream permission          We ll use the current URL as the redirect uri  so we don t          need to specify it here         login url    facebook- gt getLoginUrl  array   scope    gt   publish stream             echo  Please  lt a href       login url      gt login  lt  a gt                 gt            lt  body gt    lt  html gt     You can find more examples in the Facebook Developers site   https   developers facebook com docs reference php
