Thanks!

Hello, I have what I hope to be a very simple question..

I have built a game in flash and for my high score table I simply want to request the high scores in reverse.. i.e the lowest score first..

here is my php.. please help, thanks in advance !! :-

<?php
include("sqldialog.php");

$table = $_POST['tab'];


$recept = SelectDatas($table, "name, score, dategame", "id > 0", "score desc");
if ($recept) {
   $i = 0;
   foreach ($recept as $rec) {
      $i++;
      if ($i==1) {
      $result .= "pseudo$i=".$rec['name']."&score$i=".$rec['score']."&dategame$i=".$rec['dategame'];   
      }
      else {
      $result .= "&pseudo$i=".$rec['name']."&score$i=".$rec['score']."&dategame$i=".$rec['dategame'];
      }
   }
   echo $result;
}
else { echo "BAD, $pseudo, $score, $dategame,$ipclient"; }
?>

PHP/MYSQL - - -  Thank you in advance for any help.   Quick question.   I am calc'ing whether each line db output is a win/loss/tie below.   Outputting $res in each line.     Is there a simple way to COUNT the number of instances where $ res = "win" or loss or tie?

I'd like to put an "overall" record at the top of the output.   For example, for a given query, this chosen team's record is x WINS, Y Losses, Z TIES.   Win/Loss/Tie is NOT a field in the db table.

I know how to pull the total # of records pulled, but not this.

Example
User pulled a certain team to see game scores.

7 - 3 - 2 is their record. is what i'm trying to figure out

Game       Result       Score     Score opp     Date
game10     WIN *          7            2                blah
game11     LOSS*         2             3                ....
....

Code: [Select]
//winloss begin works * above is a result of this code
    if ($row['sch_uba_score'] > $row['sch_opp_score'])
        $res = 'Win';
    elseif ($row['sch_uba_score'] < $row['sch_opp_score'])
        $res = 'Loss';
    else
        $res = 'Tie';

// winloss end works

Hi all

I have some code that displays the high scores for a game.

Unfortunately, if a user has more than 1 high score in the table all scores for that user are displayed.

I would like to only display the highest score per user.

My Current Code
Code: [Select]
$sql_query = sprintf("SELECT * FROM `highscores` WHERE `gameID` = '106'  ORDER BY `score` DESC");
//store the SQL query in the result variable
$result = mysql_query($sql_query);
if(mysql_num_rows($result))
{
//output as long as there are still available fields
while($row = mysql_fetch_row($result))
{
echo ("$row[3] Scored :$row[5] <br>");
}
}
//if no fields exist
else
{
echo "no values in the database";
}
mysql_close($con);
OutPut

User1       300
User1       298
User 2      297
User1       296
User3       295
User2       290


I would like the output to be

User1       300
User 2      297
User3       295

Any help is much appreciated

I would like to create something like foursquare badges. When ppl upload files, the most downloaded files will have a new badge, how do i create that?

I am trying to figure out how to assign a number rank to a set of results, but I need to reset the ranking when a certain column changes.  For example:

Brand    Rank
a   1
a   2
a   3
b   1
b   2
b   3

I set $rank=0; and then for each item in my loop I add $rank++;  How do I get the rank to reset in the loop when the brand changes?  Thanks for any help.

Hey guys and girls,

Okay so am trying to provide a rank for each user within my database but I cant seem to get it working here is my code

Code: [Select]
SELECT

`Table`.`Id`,
`Table`.`Photo`,
`Table`.`Fname`,
`Table`.`Lname`,
`Table`.`Gender`,
`Table`.`Gd`,
`Table`.`Bd`,
`Table`.`Point`,

(SELECT COUNT(*) + 1 FROM
(SELECT U.Id, T.`User Id` FROM `u_account` U
LEFT JOIN `score_system` T ON `T`.`User Id` = `U`.`Id`) x

WHERE Table.Point > (SELECT SUM(Good)-SUM(Bad) FROM `score_system` GROUP BY `User Id`)
) AS RANK

FROM
(SELECT
`C`.`Id`,
`C`.`Photo`,
`C`.`Fname`,
`C`.`Lname`,
`C`.`Gender`,

CASE WHEN COALESCE( SUM(`S`.`Good`), '') = '' THEN '0' ELSE SUM(`S`.`Good`) END AS Gd,
CASE WHEN COALESCE( SUM(`S`.`Bad`), '') = '' THEN '0' ELSE SUM(`S`.`Bad`) END AS Bd,

CASE WHEN COALESCE( SUM(`S`.`Good` - `S`.`Bad`), '') = ''
THEN '0' ELSE SUM(`S`.`Good` - `S`.`Bad`) END AS Point

FROM
`u_account` AS `C`
LEFT JOIN `score_system` AS `S` ON `C`.`Id` = `S`.`Child Id`

AND (SELECT Start FROM event_schedule WHERE CURDATE() >= Start AND End >= CURDATE()) < `S`.`Date`
AND (SELECT End FROM event_schedule WHERE  CURDATE() >= Start AND End >= CURDATE()) > `S`.`Date`

GROUP BY `C`.`Id`

) AS `Table`

ORDER BY Point DESC, Fname ASC

I cant seem to pull the users rank from this and its donig my head in I've tried different things and they all dont work this is perhaps as close as I've got to figuring it out.

This is the part that creates the users rank now its saying the Subquery returns more than 1 row but I just cant seem to think of away to implement this into my query above so that it displays the rank for each user.

Code: [Select]
(SELECT COUNT(*) + 1 FROM
(SELECT U.Id, T.`User Id` FROM `u_account` U
LEFT JOIN `score_system` T ON `T`.`User Id` = `U`.`Id`) x

WHERE Table.Point >= (SELECT SUM(Good - Bad) FROM `score_system` GROUP BY `User Id`)
) AS RANK

I'm also looking for this to display the same rank for both users with the same points so If bill and ben have 200points then they would both have the same rank but if bill was to have 201points then he would be higher up than ben.

So can anyone lend me a hand.

Thanks in advance

I have a txt file of numbers e.g. 1,4,3,5,19,3,11 all in a column. Is it possible to echo only the highest 3 numbers?

Hello,

I'm in need of assistance trying to get this PHP Script working and I'm hoping you'll be able to find a solution.

What am I trying to accomplish? Simple Ranking System...

Basically, The total points is stored into total_points field for each user and whoever has the highest score will be Ranked #1 and count down to a the full database (Currently at 12,641 users)

Now the above function getUserRank is the code I pulled from the above source listed, I think my issue relies in the function of getAllUsersOrderedByPoints(); - I've tried doing something like.

Code: [Select]
$row = mysql_fetch_array($getRankResult);

Then adding:

    $userArray = $row["user_id"];

Didn't work - So if you can help me correct this than I'll be greatly appertiated.

Lastly, I've tried doing:

Code: [Select]
$index = 1;
  while ($data = mysql_fetch_array($getRankQuery)) {
    echo $index++ . " " . $data["id"] . " ".$data["user"]." <br>\n";
}

This solution works, but this solution would not work for when a "User is Search" it would count them as the highest rank 1,2,3 and wouldn't work, so either the function up there needs to be corrected or please help get a working solution, I've been googleing this issue and seems too be a common code issue with a lot people are having and not many solutions.

The application that records data (Not PHP) doesn't store any data with a "Rank" table otherwise this would be a simple echo'ed out data.

For a better understanding of what I'm trying to do - You may take a look at: http://justonemoreblock.com/lb/leaderboards.php

Hello everyone... I made point system that ranks users in my app.  There are two parts to the system, a primary score and a dynamic score.  The primary score is based on how you well you perform and the dynamic score is based on how well your friends perform.  Both of these get added together to equal your total score.  The problem is that I have a lot of looping occurring which results in about 400 queries being run when I access the page that executes this class.  Can this be optimized?  What's the best way to do this?  I don't want to store the data as I want this presented in real-time.

Hello everyone...

My following code is supposed to order rank by from Greatest covertaction but for some reason it is ranking the greatest last eg.
900,000 Rank 1
900,001 Rank 2
900,002 Rank 3

Here is the code:

Code: [Select]
<?php
$q = "SELECT * FROM `accountinfo_db` ORDER BY `covertaction`, `anticovertaction` ASC";
$res = mysql_query($q) or die(mysql_error());
$i = 1;
while($player=mysql_fetch_array($res)){
$id = securevar($player['id']);
$time = time();
$user = securevar($player['username']);
$q = "UPDATE `accountinfo_db` SET `covertrank` = '$i', `lastTurnTime` = '$time' WHERE `id` = '$id'";
