这是代码。每当我输入数据时它都工作正常。它正确地计算了除了游戏 #9 之外的每一行。除第 9 场比赛外，每场比赛均正确计数。我坐下来向三个人寻求帮助。现在我请你帮我找出为什么会发生这种情况。
这是代码:
<?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>" . $resultat . "</strong> i matchen.";
}
}
我包含了整个代码部分，因为我不知道代码的错误部分在哪里。它应该位于后面的部分:
//------------------Kolla om du ska få poäng för ditt tips---------------\\
但我看不出问题所在。
我在游戏 9 中输入 2-1。这是数据库的输入:(我不知道如何在这个网站上制作一个表格)
bet_id game_id tips resultat name poäng
9 9 1 2-1 Player 1 2
57 9 x 1-1 Player 2 0
105 9 x 1-1 Player 3 0
153 9 1 2-0 Player 4 0
201 9 1 2-1 Player 5 2
249 9 1 3-0 Player 6 0
297 9 x 1-1 Player 7 0
345 9 x 0-0 Player 8 0
393 9 2 0-1 Player 9 1
441 9 1 1-0 Player 10 0
489 9 2 0-3 Player 11 1
537 9 x 0-0 Player 12 0
585 9 x 1-1 Player 13 0
633 9 1 2-0 Player 14 0
681 9 2 1-2 Player 15 1
729 9 2 0-1 Player 16 1
777 9 x 1-1 Player 17 0
825 9 1 3-0 Player 18 0
873 9 2 2-3 Player 19 1
921 9 2 0-1 Player 20 1
969 9 x 2-2 Player 21 0
1017 9 x 2-2 Player 22 0
1065 9 2 2-1 Player 23 3
1113 9 x 0-0 Player 24 0
1161 9 2 1-1 Player 25 1
正如您所看到的，一些玩家因犯错而获得积分。有些人会因为正确的结果而获得积分，但不会因为猜测谁赢得了比赛而获得积分。
有人可以帮我找出问题所在吗？
最佳答案
首先计算$tips:
if ($lag1>$lag2){
$tips="1";
}
然后，用数据库结果覆盖它:
//------------------CHECK IF YOU SHOULD BE GETTING POINTS FOR A CORRECT GUESSED RESULT---------------\\
/* ... */
$tips = $row['tips'];
其中一个变量应具有不同的名称。
一些进一步的问题:
$resultat= $_POST['namn'];
我假设 $resultat 是游戏的结果，'namn' 是玩家的名字。这不可能是正确的。
$lag1=substr($resultat, 0,1);
$lag2=substr($resultat, 2,1);
如果一支球队在一场比赛中进球超过 9 个怎么办？你应该explode以'-'作为分隔符的结果。
