Does not work Image Post to VK

Well, I tried to debug, so I changed almost the last line in vk.api.php, added $atts, $postType, $ntOpts:
if (isset($ret) && $ret!='') return array('postID'=>$ret, 'isPosted'=>1, 'postURL'=>'https://vk.com/wall'.$ret, 'pDate'=>date('Y-m-d H:i:s'), 'err'=>$badOut['Error'], $atts, $postType, $ntOpts);

and got changed error message
[Error] [vKontakte - vk_vtpost] - -=ERROR=- Array ( [postID] => -blabla [isPosted] => 1 [postURL] => https://vk.com/wall-blabla [pDate] => 2015-12-30 15:20:30 [err] => -=ERROR=- [0] => [1] => I [2] => ) | PostID:

So $atts is not defined and it’s null, $postType…. really? In other api (FB) there is a var $fbPostType and it has a value = $ntOpts.
$ntOpts here is I [2] so… I guess your code would never work.

Any ideas?

I am not sure why you are comparing Facebook code with VK code. They work 100% differently.

We just need to send only image URL to Facebook.

We need to download the whole image internally to the script, save to the temporary folder, and then upload it to VK via either CURLFile class or by reference.

if you are getting empty $atts it means nxs_uplImgtoVK function (from the same vk.api.php) failed somewhere where it doesn’t log the problem.

Well, I just need to research because the plugin is not work as it should.
It looks like the plugin is not trying to upload any image.

This is my $options:
Array ( [doVK] => 1 [nName] => vk_vtpost [vkAppID] => Myappid [uPass] => [catSel] => 0 [catSelEd] => [postType] => I [attch] => 0 [attchAsVid] => 0 [imgUpl] => 0 [addBackLink] => 0 [msgFrmt] => test098 [rpstDays] => 0 [rpstHrs] => 0 [rpstMins] => 0 [rpstOn] => 0 [rpstStop] => O [rpstOnlyPUP] => 0 [fltrsOn] => 0 [rpstBtwDays] => Array ( ) [url] => https://vk.com/blablabla [vkPgID] => blablabla [apVKAuthResp] => https://api.vkontakte.ru/blank.html#access_token=blabla[vkAppAuthToken] => blabla [vkAppAuthUser] => bla [pgIntID] => -bla [rpstRndMins] => 0 [rpstPostIncl] => 0 [rpstType] => 2 [rpstTimeType] => A [rpstFromTime] => [rpstToTime] => [rpstOLDays] => 30 [rpstNWDays] => 365 [tagsSel] => [tagsSelX] => [vkSvC] => N; [ii] => 0 [pType] => aj [isPosted] => 1 [imgToUse] => [urlToUse] => https://.../2015/12/29/test5/ [imgSize] => ) )

[imgUpl] => 0 – what does it mean? Where does it stored?

[imgUpl] => 1 – I changed it, and nothing changed.
What else variables do I need to inspect?
Where is located the $tmp dir?

Well, I dumped curl

Guys… I don’t know what to say. I am not a programmer, I’m just a regular user, but I had to spend 3 days debugging your code, dumping variables and investigating requests and responses.
And. The plugin has a major bug.

function nxs_uplImgtoVK($imgURL, $options){
      $postUrl = 'https://api.vkontakte.ru/method/photos.getWallUploadServer?gid='.(str_replace('-','',$options['pgIntID'])).'&access_token='.$options['vkAppAuthToken'];

URL of vk api is api.vk.com.
Fix it, please.

Thank you for your poor help.
