Is the person subscribed to such a group and did he leave photos there?

Question

PHP

Good day! Is it possible to find out somehow through the VK API whether a person is subscribed to the same groups as me and whether he left photos there? How can this be done in JS? Thanks in advance.

Answer 1

The users.getSubscriptions() method returns the user's subscriptions. If user_id is not specified, it will return your subscriptions. Here is such a simple code in the execute() procedure (insert it right on that page and “Execute”) will return two arrays: yours and its group id:

var uid=12345; 
return {
  "my": API.users.getSubscriptions().groups.items,
  "her": API.users.getSubscriptions({"user_id":uid}).groups.items
};

The first line specifies the id of "that user" with whom to compare.
These two arrays remain to be compared. You can execute the following code in the scratchpad of the browser:

var r = 
{"response":.....} // тут целиком ответ из метода execute
;                  // и точка-с-запятой в конце.
var common = [];   // сюда попадут id общих групп
for(var i=0;i<r.response.my.length;i++){
  if( !!~r.response.her.indexOf( r.response.my[i])) 
    common.push(r.response.my[i]);
}
common;   // если в Scratchpad Firefox'а нажать Ctrl+L, 
          // код выполнится а в коммент вставится содержание этого массива

Whether you posted photos - you need to view the entire photo using the photos.getAll() method . The owner_id parameter - in turn, each of the common groups. For each photo, look at the value of the user_id field - you need only those where it is equal to the desired user.
For one method call, you can get up to 200 photos, so add the parameter count=200 and scroll through the offset parameter 200 images deep into the history. You can again use the execute method to charge the collection - this will be 25 * 200 = 5000 photos per call.
