Answer 1

not connected to base

Maybe it has something to do with the fact that you are passing a variable instead of a username into the connection that is not initialized in any way and into which the name of the database is later written and which has the incorrect name db_table ?
By the way, they directly write to you in the error message that this is the problem.

how to fix?

Pass the correct username, correct password to the connection, and verify that this user has the required access rights.

//           (“хост”,      “имя пользователя”, “пароль”)
mysql_connect("localhost", $db_table,          "901kiril")
                           ^^^ проблема ^^^

Answer 2

On the first line, replace $db_table with $user_name. Having previously initialized this variable with the correct login to access the database. And everything will work immediately :-)
