PHP - Php Not Printing First Record From A Query

I have 64 rows of players and want each User to be able to choose to bookmark an player, as well as unbookmark it too.

I have a bookmark table set up, and each time a User decides to bookmark(+) or unbookmark(-) an player a row is created in the data table.   (Matching the player ID and User ID) That's working fine.  

A query reads the most recent row for each player to determine if there is a + or - button next to each player.  Testing the query and adding some dummy data, that part of it works too.  However, the issue is the initial state, which I want to be a +.  Once I go live, the table will be empty, nothing for the query to return/produce.

How do I create an initial state of a + with no rows and have it not used or swapped out when Users start clicking + or -?

  $query = "SELECT b.id, bookmark,playerID,userID,p.id 
                FROM a_player_bookmark b
                LEFT JOIN a_players p
                ON '". $id ."' = playerID
                WHERE userID = '". $userID ."'&&'". $id ."' = playerID
                ORDER BY b.id desc
                LIMIT 1
                ";

    $results = mysqli_query($con,$query);
    echo mysqli_error($con);
    while($row = mysqli_fetch_assoc($results)) {    

    echo $row['bookmark'];

        if($row['bookmark'] == 0) {
            echo '-'; // this is where a form goes to remove a bookmark
        }       
        else {
            echo '+'; // this is where a form goes to add a bookmark
        }

    }   

I tried to get it with CASE, but I don't think that's the right path.  I also looked at UNION.  I was able to get it to produce an initial state of +, but it still printed the already made up sample data too (so I have three instances of ++ or +-).

 (Players 2, 4 and 4)

Here is the what the UNION query looked like:

	$query = "(SELECT b.id, bookmark,playerID,userID,p.id 
				FROM a_player_bookmark b
				LEFT JOIN a_players p
				ON '". $id ."' = playerID
				
				WHERE userID = '". $userID ."'&&'". $id ."' = playerID
				ORDER BY b.id desc
				LIMIT 1)
			UNION
				(SELECT b.id, bookmark,playerID,userID,p.id 
				FROM a_player_bookmark b
				LEFT JOIN a_players p
				ON '". $id ."' = playerID
				
				WHERE userID = '". $userID ."'
				ORDER BY p.id desc
				LIMIT 1) 
				";

case "update-delete":
	if(isset($_POST['highlight-purchased'])) 
		{
			// ****** Setup customized query to obtain only items that are checked ******
			$sql = "SELECT * FROM shoplist WHERE";
					for($i=0; $i < count($_POST['checkboxes']); $i++)
						{
							$sql=$sql . " idnumber=" . $_POST['checkboxes'][$i] . " or";
						}
					$sql= rtrim($sql, "or");
											
			$statement = $conn->prepare($sql);
			$statement->execute();
																						
			// *** fetch results for all checked items (1st query) *** //
			$result = $statement->fetchAll();

			$statement->closeCursor();
											
			// Setup query that will change the purchased flag to "N", if it's currently set to "Y"
			$sqlSetToN = "UPDATE shoplist SET purchased = 'N' WHERE purchased = 'Y'";
											
			// Setup query that will change the purchased flag to "Y", if it's currently set to "N", "", or NULL
			$sqlSetToY = "UPDATE shoplist SET purchased = 'Y' WHERE purchased = 'N' OR purchased = '' OR purchased IS NULL";

			$statementSetToN = $conn->prepare($sqlSetToN);
			$statementSetToY = $conn->prepare($sqlSetToY);
											
			/*** loop through the results/collection of checked items ***/
			foreach($result as $row)
				{
					if ($row["purchased"] != "Y")
						{
							// *** fetch one row at a time pertaining to the 2nd query *** //
							$resultSetToY = $statementSetToY->fetch();
															
							foreach($resultSetToY as $row)
								{															
									$statementSetToY->execute();																
								}
						}
					else
						{
							// *** fetch one row at a time pertaining to the 2nd query *** //
							$resultSetToN = $statementSetToN->fetch();
															
							foreach($resultSetToN as $row)
								{															
									$statementSetToN->execute();																
								}
						}
				}
				break;
