Search feature not working at all

Hi, I'm stuck in this course while trying to figure it out why my search feature won't work in any way

function search_catalog_array($search, $limit = null, $offset = 0){
  include('connection.php');
  //$category = strtolower($category);
  try {
    $sql = "SELECT media_id, title, category, img
            FROM Media
            WHERE title LIKE ?
            ORDER BY
            REPLACE (
              REPLACE(
                REPLACE(title, 'The ', ''),
                'An ',
                ''
              ),
              'A ',
              ''
            )";

    if(is_integer($limit)){
      $results = $db->prepare($sql . " LIMIT ? OFFSET ? ");
      $results->bindValue(1, "%".$search."%", PDO::PARAM_STR);
      $results->bindParam(2, $limit, PDO::PARAM_INT);
      $results->bindParam(3, $offset, PDO::PARAM_INT);
    }else{
      $results = $db->prepare($sql);
      $results->bindValue(1, "%".$search."%", PDO::PARAM_STR);
    }
    $results->execute();
  } catch (Exception $e) {
    echo "Unable to retrieved results";
    exit;
  }

  $catalog = $results->fetchALL(PDO::FETCH_ASSOC);
  return $catalog;
}
function get_catalog_count($category = null, $search = null){
  $category = strtolower($category);
  include('connection.php');

  try {
    $sql = "SELECT COUNT(media_id) FROM Media";
    if(!empty($search)){
      $result = $db->prepare(
        $sql
        . " WHERE title LIKE ?");
      $result->bindValue(1, "%".$search."%", PDO::PARAM_STR);
    }elseif(!empty($category)){
      $result = $db->prepare(
        $sql
        . " WHERE LOWER(category) = ?"
      );
      $result->bindParam(1, $category, PDO::PARAM_STR);
    }else{
      $result = $db->prepare($sql);
    }
    $result->execute();
  } catch (Exception $e) {
    echo "Bad query";
    echo $e;
  }

  $count = $result->fetchColumn(0);
  return $count;

}

Those are the two main functions that are being used (at least I think so). I checked the syntax numerous times and I can't figure out what it is that I'm doing wrong.

Thanks for any help!

I don't think anything is wrong with your functions code in functions.php because it matches up with mine and I just got my search function to work. I was having the same problem until I downloaded the file in the following video and compared her code to mine. The problem for me was in catalog.php I didn't use this if statement:

if (empty($current_page)) { $current_page = 1; }

After I implemented the code it worked perfectly. I hope this helps anyone who's also struggling with this.
