ignores the expression

  $sql = "UPDATE ".$mysqli_table." SET `status`= '1' WHERE `id` = '".$_GET['id']."'";
  $result = mysqli_query($db, $sql);
}

Answer 1

Try changing the if yourself:
if (isset($_GET['id']) && ($_GET['id'] != ''))

Answer 2

There is an obvious error here:
You need this:
if (isset($_GET['id']) && $_GET['id'] != '') {

Answer 3

$result = mysqli_query($db, $sql);
php.net/manual/en/mysqli.query.php
sql code should be in the first parameter. read the function's documentation before using it.
read about sql injection and filtering incoming data
