Why isn't this code working?

It's telling me to add a where clause to select a single member_id.......

index.php 
<?php
function get_member($id) {
    include("connection.php");

    try {
      $results = $db->query(
          "SELECT member_id, email, fullname, level
          FROM members
          WHERE member_id = $id"
      );
    } catch (Exception $e) {
      echo "bad query";
    }

    $member = $results->fetch();
    return $member;
}

you should use place holders and prepare method, this should pass all three tasks;

function get_member($member_id) {
    include("connection.php");

    try {
      $results = $db->prepare(
          "SELECT member_id, email, fullname, level
          FROM members
          WHERE member_id = ?"
      );

$results->bindParam(1,$member_id,PDO::PARAM_INT);
$results->execute();

    } catch (Exception $e) {
      echo "bad query";
    }

    $members = $results->fetchAll();
    return $members;
}

Thanks, that did work, but I think it might of been because I changed $results->fetchAll(); to $results->fetch(); and you didn't. I had tried the prepare method and that failed as well

fetch(); is just fine as well with the first task, but it requires fetchAll(); for 2nd and 3rd tasks, workspaces can be tricky sometimes, as long as you understand the structure more or less it doesn't matter I guess. have fun.
