如何編輯我現有的php函數並添加另一個檢查？

Question

我想爲高級帳戶添加另一個選項。目前，你可以每兩天改變一次角色，但是我希望再添加一次支票，以保證優質用戶每12小時一次。他們從PREMIUM中的另一個表中確定，它們的編號爲strAccountID如果它們不是溢價，那麼該表中將不會有行中的行。

這是我目前使用的PHP函數，適用於所有用戶，並允許他們每兩天完成一次。

private function doProcessClassChangeFormD() 
{ 
    $db = $this->database[GDB]; 
    $character = $this->site->SanitizeName($_POST['character']); 
    $num_rows = $db->doQuery('SELECT bNation FROM ACCOUNT_CHAR WHERE strAccountID = ? AND ? IN(strCharID1, strCharID2, strCharID3)', $_SESSION['strAccountID'], $character); 
    if ($num_rows == -1) 
    { 
     $db->GetError(__file__, __line__); 
     $this->m_ccError = Template::GetLangVar('DB_ERROR'); 
     return false; 
    } 
    else if ($num_rows == 0) 
    { 
     $this->m_ccError = Template::GetLangVar('CC_INVALID_ACCOUNT'); 
     return false; 
    } 

    $row = $db->doRead(); 
    $nation = $row['bNation']; 

    $num_rows = $db->doQuery('SELECT Class, Race, Strong, Sta, Dex, Intel, Cha, Points, TransferTime FROM USERDATA WHERE strUserId = ? AND (TransferTime < DATEADD(DAY,-2,GETDATE()) OR TransferTime IS NULL) and zone<>199 and authority<>255', $character); 
    if ($num_rows == -1) 
    { 
     $db->GetError(__file__, __line__); 
     $this->m_ccError = Template::GetLangVar('DB_ERROR'); 
     return false; 
    } 
    else if ($num_rows == 0) 
    { 
     $this->m_ccError = Template::GetLangVar('CC_RECENT_TRANSFER'); 
     return false; 
    } 

    $row = $db->doRead(); 

    $oldRace = $row['Race']; 
    $oldClass = $row['Class']; 
    $newRace = intval($_POST['race']); 
    $newClass = intval($_POST['class']); 

    $pCT = new ClassTransfer($nation, $oldClass, $oldRace, $newClass, $newRace); 
    if (!($res = $pCT->canChangeClass())) 
    { 
     $this->m_ccError = $pCT->GetError(__file__, __line__); 
     return false; 
    } 

    $newClass = $res[0]; 
    $newRace = $res[1]; 

    $free = $row['Points'] + $row['Strong'] + $row['Sta'] + $row['Dex'] + $row['Intel'] + $row['Cha']; 
    $newStats = $pCT->getStarterStats($newClass, $newRace); 

    for ($i = 0; $i < 5; $i++) 
     $free -= $newStats[$i]; 

    if ($free > 255) 
    { 
     $_SESSION['bClassTransfer'] = true; 
     $_SESSION['strUserId'] = $character; 
     $_SESSION['bNewRace'] = $newRace; 
     $_SESSION['bNewClass'] = $newClass; 
     $_SESSION['bStrong'] = $newStats[KO_STR]; 
     $_SESSION['bStamina'] = $newStats[KO_STA]; 
     $_SESSION['bDexterity'] = $newStats[KO_DEX]; 
     $_SESSION['bIntelligence'] = $newStats[KO_INT]; 
     $_SESSION['bCharisma'] = $newStats[KO_CHA]; 
     $_SESSION['bAvailable'] = $free; 

     $this->m_bSelectPoints = true; 
     return false; 
    } 

    $newStats[5] = $free; 
    return $this->doExecuteClassChangeD($character, $newClass, $newRace, $newStats); 
}

我試過多種方法，但沒有成功。我如何實現這一目標？

Answer 1

去了解它是做高檔表的查詢

最簡單的方法：（？存儲在會話/ cookie的地方）

從PREMIUM選擇的strAccountID其中strAccountID等於登錄的用戶當前

從那裏做一個簡單的if語句。如果上面的select語句返回一行並且時間大於12小時，那麼是讓他們改變角色。

執行上述解決此位的位置：

$num_rows = $db->doQuery('SELECT Class, Race, Strong, Sta, Dex, Intel, Cha, Points, TransferTime FROM USERDATA WHERE strUserId = ? AND (TransferTime < DATEADD(DAY,-2,GETDATE()) OR TransferTime IS NULL) and zone<>199 and authority<>255', $character); 

然後，所有你需要做的是，如果這個人是溢價，改變上述聲明只有12小時，而不是2天。如果它們不是優質的，那麼在2天內放置它。

Answer 2

使用LEFT JOIN與查詢中的PREMIUM表檢查傳輸時間。然後使用該表中的匹配條件化您與之比較的時間。

$num_rows = $db->doQuery(' 
    SELECT Class, Race, Strong, Sta, Dex, Intel, Cha, Points, TransferTime 
    FROM USERDATA u 
    LEFT JOIN PREMIUM p ON p.strAccountID = u.strUserId 
    WHERE strUserId = ? 
     AND (TransferTime < IF(p.strAccountId IS NULL, 
          DATEADD(DAY,-2,GETDATE()), 
          DATE_SUB(NOW(), INTERVAL 12 HOUR))) 
      OR TransferTime IS NULL) 
     AND zone<>199 and authority<>255', $character);
