Check if Safari block cookies "From third parties and advertisers" is enabled using javascript/php -

-

I am facing a problem that in my website payment gateway (MiGs) as an iframe in the Safari Browser Using the default cookie block is "by third parties and advertisers", so the gateway (migs) response is receiving a "cookie not enabled error" error. I would like to detect such a cookie block by using php / javascript to show this cookie block problem.

Edit:

I am facing a single problem, since the IOS7 "Block cookies from third parties" is disabled Stopping my LinkedIn social login button to work. In the lack of a solution, I'd love to know how they are enabled with Javascript or PHP + Lisovaccaro

I think one way of doing this is to have a script on another domain (no subdomain, but I have not tested it), which sets a cookie, and then the script can return JSONP so that You can use it on other domains with Javascript Can. So something like this:

PHP (cookie.php) 

  & lt; Php header ("content-type: app / javascript"); Header ("Cash-Control: No-Store, No-Cash, Sure-Modified, Maximum-Age = 0"); Header ("cache-control: post-check = 0, pre-check = 0", false); Header ("Prestama: no-cache"); If (isset ($ _GET ["set"])) {// first run here setcookie ("cookie_test", "cookies", time () + 3600); // After redirecting the cookie, redirect yourself so that we do not need to call the script twice as headers ('location: cookies.fp? & Amp; amp; callback ='. '$ _GET ["callback"]; ); // death} // should be redirected once $ cookie_set = array ("cookies" => gt; isset ($ _COOKIE ["cookie_test"]); resonance @ $ _ GET ["callback"] "(" .json_encode ($ cookie_set). ");   
 javascript / jquery  
  // callback =? Jquery to know this jsonp Set to & Amp; so that script initiatives $ $ .getJSON be set ("http://another.domain.com/cookies.php?callback=?&set") .done (function) {if (data.cookies) {// third party cookies Enabled} other {// third party cookies are probably disabled}})   
. It was tested on Safari on map.

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
