查詢確實除第9行以外的所有行都正確

Question

這是代碼。每當我輸入數據，它工作正常。它會正確計數每一行，除了遊戲＃9。每場比賽都被正確計算，但是比賽＃9。我坐了下來，問了3個人的幫助。現在我轉向你，幫助我弄清楚爲什麼會發生這種情況。

這是代碼：

<?php 

include ("../conn_inc.php"); 
include ("../conn_inc_pdo.php"); 
require_once ('auth.php'); 

$game_id= $_POST['game_id']; 
$resultat= $_POST['namn']; 
$lag1=substr($resultat, 0,1); 
$lag2=substr($resultat, 2,1); 


if ($lag1>$lag2){ 
    $tips="1"; 
} 
if ($lag1<$lag2){ 
    $tips="2"; 
} 
if ($lag1==$lag2){ 
    $tips="x"; 
} 

//echo $tips; 

    //------------------FIND ALL ALREADY POSTED GAMES---------------\\ 

    $sql2 = $pdo->prepare("SELECT game_id FROM vm2014res WHERE :game_id = game_id"); 
    $sql2->execute(array(':game_id' => $game_id)); 

    if ($sql2->rowCount() == 0) { 

     //------ IRRELEVANT TEST CODE 3 LINES DOWN-----\\ 
     echo $game_id; 
     echo $resultat; 
     echo "<br>"; 


      //----------- INSERT THE VALUE OF THE GAME IF IT DOESNT EXIST -------\\ 
      $q = "INSERT INTO vm2014res (game_id, resultat, added) VALUES (:game_id, :resultat, CURRENT_TIMESTAMP)"; 
      $query = $pdo->prepare($q); 
      $query->execute(array(
       ':game_id' => $game_id, 
       ':resultat' => $resultat 
       )); 

        //------------------CHECK IF YOU SHOULD BE GETTING POINTS FOR A CORRECT GUESSED RESULT---------------\\ 
      $SQL = $pdo->prepare("SELECT * FROM vm2014 WHERE game_id = :game_id AND resultat = :resultat"); 
      $SQL->execute(array(':game_id' => $game_id, ':resultat' => $resultat)); 
      $r = $SQL->fetchAll(PDO::FETCH_ASSOC); 
      foreach($r as $row){  


       $bet_id = $row['bet_id']; 
       $game_id = $row['game_id']; 
       $tips = $row['tips']; 
       $resultat = $row['resultat']; 
       $namn = $row['namn']; 
       $points = $row['points']; 

       //-------- ALL ECHOS DOWN HERE ARE IRRELEVANT----------\\ 
       echo $bet_id; 
       echo $game_id; 
       echo $tips; 
       echo $resultat; 
       echo $namn; 
       echo $points; 
       echo "<br>"; 
       $points=$points+2; 
       echo $points; 

    //------------- UPDATE THE POINTS GOTTEN (2 POINTS)---------\\ 

      $sql2 = $pdo->prepare("UPDATE vm2014 SET points = :points WHERE bet_id = :bet_id"); 
      $sql2->execute(array(':points' => $points, 
      ':bet_id' => $bet_id 
      )); 

      } 

      //------------------CHECK IF YOU SHOULD BE GETTING POINTS FOR RIGHT GUESSED GAME---------------\\ 
      $SQL = $pdo->prepare("SELECT * FROM vm2014 WHERE game_id = :game_id AND tips = :tips"); 
      $SQL->execute(array(':game_id' => $game_id, ':tips' => $tips)); 
      $r = $SQL->fetchAll(PDO::FETCH_ASSOC); 
      foreach($r as $row){  


       $bet_id = $row['bet_id']; 
       $game_id = $row['game_id']; 
       $tips = $row['tips']; 
       $resultat = $row['resultat']; 
       $namn = $row['namn']; 
       $points = $row['points']; 

      //-------IRRELEVANT ECHOS DOWN HERE--------\\ 
       echo $bet_id; 
       echo $game_id; 
       echo $tips; 
       echo $resultat; 
       echo $namn; 
       echo $points; 
       echo "<br>"; 
       $points=$points+1; 
       echo $points; 

    //----------------- UPDATE YOUR POINTS IF YOU SHOULD BE GETTING POINTS FOR THE GAME----\\ 

      $sql2 = $pdo->prepare("UPDATE vm2014 SET points = :points WHERE bet_id = :bet_id"); 
      $sql2->execute(array(':points' => $points, 
      ':bet_id' => $bet_id 
      )); 

      } 

    } else { 
     //-----------------POST WHEN THE GAME RESULT WAS ADDED TO THE DB-------\\ 
      $SQL6 = $pdo->prepare("SELECT * FROM vm2014res WHERE game_id = :game_id"); 
      $SQL6->execute(array(':game_id' => $game_id)); 
      $ra = $SQL6->fetchAll(PDO::FETCH_ASSOC); 
      foreach($ra as $row){ 

       $game_id = $row['game_id']; 
       $resultat = $row['resultat']; 
       $added = $row['added']; 

     echo "Resultatet är redan registrerat. Det registrerades: <strong>" . $added . "</strong> och det vart <strong>" . $resultat . "</strong> i matchen."; 
      } 
    } 

IVE包括代碼的整個部分，因爲我不知道在哪裏的代碼錯誤部分。它應該在以下部分：

//------------------Kolla om du ska få poäng för ditt tips---------------\\ 

但我不能看到問題。

IM輸入2-1進入比賽9，這是輸入到數據庫中：（我不知道如何使這個表本網站上）

 
    bet_id game_id tips resultat name  poäng 
    9   9 1  2-1   Player 1 2 
    57   9 x  1-1   Player 2 0 
    105   9 x  1-1   Player 3 0 
    153   9 1  2-0   Player 4 0 
    201   9 1  2-1   Player 5 2 
    249   9 1  3-0   Player 6 0 
    297   9 x  1-1   Player 7 0 
    345   9 x  0-0   Player 8 0 
    393   9 2  0-1   Player 9 1 
    441   9 1  1-0   Player 10 0 
    489   9 2  0-3   Player 11 1 
    537   9 x  0-0   Player 12 0 
    585   9 x  1-1   Player 13 0 
    633   9 1  2-0   Player 14 0 
    681   9 2  1-2   Player 15 1 
    729   9 2  0-1   Player 16 1 
    777   9 x  1-1   Player 17 0 
    825   9 1  3-0   Player 18 0 
    873   9 2  2-3   Player 19 1 
    921   9 2  0-1   Player 20 1 
    969   9 x  2-2   Player 21 0 
    1017  9 x  2-2   Player 22 0 
    1065  9 2  2-1   Player 23 3 
    1113  9 x  0-0   Player 24 0 
    1161  9 2  1-1   Player 25 1 

，正如你所看到的，一些球員因錯誤而獲得積分。有些人得到正確結果的積分，但沒有得到猜測誰贏了比賽。

有人可以幫助我搞清楚最新的錯誤嗎？

Answer 1

首先你calucate $tips：

if ($lag1>$lag2){ 
    $tips="1"; 
} 

然後，您與數據庫的結果將其覆蓋：

//------------------CHECK IF YOU SHOULD BE GETTING POINTS FOR A CORRECT GUESSED RESULT---------------\\ 
/* ... */ 
$tips = $row['tips']; 

其中一個變量應該有不同的名稱。

一些進一步的問題：

$resultat= $_POST['namn']; 

我假設$resultat是博弈的結果，而'namn'是一個球員的名字。這不可能是正確的。

$lag1=substr($resultat, 0,1); 
$lag2=substr($resultat, 2,1); 

如果一個團隊在比賽中得分超過9個，該怎麼辦？你應該以'-'作爲分隔符explode的結果。
