How to solve api telegram problem with blocking users?

Question

PHP

Hello, I wrote a bot that should block absolutely all new chat users (excluding those whose username is in the database)
Here is my code:

$data = json_decode(file_get_contents('php://input'));
    if (isset($data->{'message'}->{'chat'}->{'type'}) && $data->{'message'}->{'chat'}->{'type'} == 'supergroup')
    {
      $id_user = $data->{'message'}->{'new_chat_members'}->{'id'};
      $id_chat = $data->{'message'}->{'chat'}->{'id'};
      $username_chat = $data->{'message'}->{'chat'}->{'username'};
      $username_user = $data->{'message'}->{'new_chat_members'}->{'username'};

      $query_count = mysqli_query($connect, "SELECT * FROM `telegram` WHERE `chat_username` = '".$username_chat."' AND `username` = '".$username_user."'");
      $query_count = mysqli_num_rows($query_count);
      if (!($query_count))
        file_get_contents("https://api.telegram.org/botHASH/restrictChatMember?chat_id=".$id_chat."&user_id=".$id_user);
    }

The problem is that it does not work clearly, it does not ban those who are in the database clearly, but it will ban ordinary users every other time, then not.
What is the problem here? Thanks in advance!

Answer 1

permissions needs to be sent

'can_send_messages'         => true,
'can_send_media_messages'   => true,
'can_send_polls'            => true,
'can_send_other_messages'   => true,
'can_add_web_page_previews' => true,
'can_change_info'           => true,
'can_invite_users'          => true,
'can_pin_messages'          => true,

false - to block
