Question

我有这个代码形式Ari Quiz：

obj\Debug

但是当没有回答正确的问题时，我不需要写入mysql数据库0的结果。我修改了：

$query = sprintf('UPDATE #__ariquizstatisticsinfo SET Status = %1$s,EndDate = %2$s,MaxScore = %3$f,UserScore = %4$f,UserScorePercent = %7$f, Passed = %5$d, ElapsedTime = UNIX_TIMESTAMP(%2$s) - UNIX_TIMESTAMP(StartDate) + UsedTime WHERE StatisticsInfoId = %6$d',
            $db->Quote(ARIQUIZ_USERQUIZ_STATUS_COMPLETE),
            $db->Quote($finishedDate),
            $finishedInfo['MaxScore'],
            $finishedInfo['UserScore'],
            $finishedInfo['Passed'],
            $statisticsInfoId,
            $finishedInfo['MaxScore'] > 0 ? min(round(100 * $finishedInfo['UserScore'] / $finishedInfo['MaxScore'], 2), 100.00) : 0.00

    );

但是当我完成测试时我得到了一个错误：

500 - AriQuizModelUserQuiz :: markQuizAsFinished（）：以下SQL 查询无法执行＆＃39; UPDATE #__ariquizstatisticsinfo SET状态 =＆＃39;已完成＆＃39;，EndDate =＆＃39; 2015-04-28 07：41：06＆＃39;，MaxScore = 2.700000，UserScore = esultes，UserScorePercent = 0.000000，Passed = 0，ElapsedTime = UNIX_TIMESTAMP（＆＃39; 2015-04-28 07：41：06＆＃39;） - UNIX_TIMESTAMP（StartDate）+ UsedTime WHERE StatisticsInfoId = 134＆＃39;。详情：未知专栏＆＃39; esultes＆＃39;在＆＃39;字段列表＆＃39; SQL = UPDATE joomla_ariquizstatisticsinfo SET Status =＆＃39;已完成＆＃39;，EndDate = ＆＃39; 2015-04-28 07：41：06＆＃39;，MaxScore = 2.700000，UserScore = esultes，UserScorePercent = 0.000000，Passed = 0，ElapsedTime = UNIX_TIMESTAMP（＆＃39; 2015-04-28 07：41：06＆＃39;） - UNIX_TIMESTAMP（StartDate）+ UsedTime WHERE StatisticsInfoId = 134

提前谢谢！

返回更新：我试过这段代码：

    if ($finishedInfo['UserScore'] == 0.00) 
    {
    $resultes = 1.00;
    } 
    else
    {
    $resultes = $f;
    }
    $query = sprintf('UPDATE #__ariquizstatisticsinfo SET Status = %1$s,EndDate = %2$s,MaxScore = %3$f,UserScore = %4$resultes,UserScorePercent = %7$f, Passed = %5$d, ElapsedTime = UNIX_TIMESTAMP(%2$s) - UNIX_TIMESTAMP(StartDate) + UsedTime WHERE StatisticsInfoId = %6$d',
        $db->Quote(ARIQUIZ_USERQUIZ_STATUS_COMPLETE),
        $db->Quote($finishedDate),
        $finishedInfo['MaxScore'],
        $finishedInfo['UserScore'],
        $finishedInfo['Passed'],
        $statisticsInfoId,
        $finishedInfo['MaxScore'] > 0 ? min(round(100 * $finishedInfo['UserScore'] / $finishedInfo['MaxScore'], 2), 100.00) : 0.00
    );

但我不明白为什么如果我得到结果0.00这给我1.00如果我得到超过0.00所有相同。

Answer 1

我认为你错过了一个逗号

UserScore = %4$resultes

可能是

UserScore = %4$,resultes

Answer 2

感谢我所有人，但我已经解决了，现在正在努力。

   $query = sprintf('UPDATE #__ariquizstatisticsinfo SET Status = %1$s,EndDate = %2$s,MaxScore = %3$f,UserScore = case when %4$f < 1.00 then 1.00 else %4$f end,UserScorePercent = %7$f, Passed = %5$d, ElapsedTime = UNIX_TIMESTAMP(%2$s) - UNIX_TIMESTAMP(StartDate) + UsedTime WHERE StatisticsInfoId = %6$d',
   $db->Quote(ARIQUIZ_USERQUIZ_STATUS_COMPLETE),
   $db->Quote($finishedDate),
   $finishedInfo['MaxScore'],
   $finishedInfo['UserScore'],
   $finishedInfo['Passed'],
   $statisticsInfoId,
   $finishedInfo['MaxScore'] > 0 ? min(round(100 * $finishedInfo['UserScore'] / $finishedInfo['MaxScore'], 2), 100.00) : 0.00
    );

如果注释必须在sql中，而不是在php：

UserScore =％4 $ f＆lt; 1.00然后1.00否则％4 $ f结束

再次向所有人致谢！

Ari Quiz没有零结果
