I have a pretty simple query,
$query3 = $db->query("SELECT * FROM mybb_ranks WHERE id='1' ORDER by points DESC");
And what it'll return is a database of people who are registered and ranked. Since players points can be randomly changing due to matches, we determine the rank # by assigning it once the value is fetched in a way like this:
$i = 1;
while($row = mysqli_fetch_array($query5))
{
echo "$row[player]'s rank is $i";
$i++;
}
As you can see, it orders the player's by their points, but determines the rank # from a variable that adds after displaying every rank. However, in each of the user profiles, I would like to display their rank as well. This is a bit more difficult, because I need a certain way to count the amount of rows the query has to go through in order to get to the certain player. So for instance, if PlayerB is ranked at #5, I would need a way to display that on his own profile. For this to happen, I imagine the query would need to be altered to be able to count each individual row (4 rows) before it reaches the certain player on the 5th row. I was wondering, how would I go about this?
Try this:
UPDATE mybb_ranks
LEFT JOIN (
SELECT
player,
@rank:=@rank+1 as current_rank
FROM mybb_ranks
WHERE id='1'
ORDER BY points DESC
) AS t
ON mybb_ranks.player = t.player
SET mybb_ranks.rank = t.current_rank
That means you have to create additional column rank in your mybb_ranks table.
This query will update the rank of user each time you generate your ranks list.
So when you need to show user's rank in his profile page you just request it from the table:
SELECT rank
FROM mybb_ranks
WHERE player = :player_id
if you want it more dynamic, you can run this UPDATE query every time when you generate your player profile page, right before SELECT rank.
