Question

I'm having trouble displaying my league standings correctly. I have a CSV file with all teams divided by Divisions and Conferences (basically trying to display my standings like the NHL standings)

The top 3 teams of each division are displayed then the top 2 teams in the conference that are not in the top 3 of divisions are displayed.

Here is the code I have now

//Query Central //
$QueryCentral="SELECT * FROM QNHLProTeamV2 WHERE Division='$CentralDivision' ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 3";
$ResultCentral=mysql_query($QueryCentral);
$NumCentral=mysql_num_rows($ResultCentral);

//Query Pacific //
$QueryPacific="SELECT * FROM QNHLProTeamV2 WHERE Division='$PacificDivision' ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 3";
$ResultPacific=mysql_query($QueryPacific);
$NumPacific=mysql_num_rows($ResultPacific);

//Query West Wild Card //
$QueryWestWildCard="SELECT * FROM QNHLProTeamV2 WHERE Conference='$WesternConference' ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 6,20";
$ResultWestWildCard=mysql_query($QueryWestWildCard);
$NumWestWildCard=mysql_num_rows($ResultWestWildCard);

The first 2 queries work and I do get the top 3 of each division but for the Wild Card I could only figure out how to get all the teams in order without top 6. How can I display the teams that are NOT in top 3 of divisions?

Here is some code that should do the trick You will need to update the $row["TeamName"] with the actual column's name, however.

//Query Central //
$QueryCentral="SELECT * FROM QNHLProTeamV2 WHERE Division='$CentralDivision' ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 3";
$ResultCentral=mysql_query($QueryCentral);
$NumCentral=mysql_num_rows($ResultCentral);
$i=0;
while($row = mysqli_fetch_array($ResultCentral);
{
    $top[$i]="\"".$row["TeamName"]."\"";
    $i++;
}

//Query Pacific //
$QueryPacific="SELECT * FROM QNHLProTeamV2 WHERE Division='$PacificDivision' ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 3";
$ResultPacific=mysql_query($QueryPacific);
$NumPacific=mysql_num_rows($ResultPacific);
while($row = mysqli_fetch_array($ResultPacific);
{
    $top[$i]="\"".$row["TeamName"]."\"";
    $i++;
}

//Generate list - delimited by comma
$toplist = implode(",", $top);

//Query West Wild Card //
$QueryWestWildCard="SELECT * FROM QNHLProTeamV2 WHERE Conference='$WesternConference' and NOT IN ($toplist) ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 3";
$ResultWestWildCard=mysql_query($QueryWestWildCard);
$NumWestWildCard=mysql_num_rows($ResultWestWildCard);

Or, you could use this query for the wild card (looks messier):

$QueryWestWildCard="SELECT * FROM QNHLProTeamV2 
WHERE Conference='$WesternConference' 
and NOT IN (SELECT TeamName FROM QNHLProTeamV2 WHERE Division='$CentralDivision' ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 3) 
AND NOT IN (SELECT TeamName FROM QNHLProTeamV2 WHERE Division='$PacificDivision' ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 3) 
ORDER by Points DESC, GP ASC, W DESC, GoalDiff DESC LIMIT 3";
