PHPとSQLは一致しますが、スクリプトはまだ動作しません

Question

過去5時間の問題があります。私はそれを修正しようとしてきましたが、解決策を見つけることができないので、私を助けてくれることを願っています！

だから私はこのvote.phpスクリプトを持っている：ip, account, date, times, amount：

<?php 
if(basename($_SERVER["PHP_SELF"]) == "vote.php") { 
    die("403 - Access Forbidden"); 
} 
echo "<h2 class=\"text-left\">Vote</h2><hr/>"; 
$earnedpoints = false; 
$insertnew = false; 
$time = time(); 
$redirect = ""; 
$account = $mysqli->real_escape_string(preg_replace("/[^A-Za-z0-9 ]/", '', @$_POST['name'])); 
$siteid = $mysqli->real_escape_string(@$_POST['votingsite']); 
$checkacc = $mysqli->query("SELECT * FROM accounts WHERE name = '$account'"); 
$countcheckacc = $checkacc->num_rows; 
$row = $checkacc->fetch_assoc(); 
if($countcheckacc == 0 && isset($_POST['submit'])) { 
    $funct_error = "This account doesn't exist!"; 
} 
if($row['loggedin'] > 0 && isset($_POST['submit'])) { 
    $funct_error = "This account is logged in!"; 
} elseif ($account == '' && isset($_POST['submit'])) { 
    $funct_error = 'You need to put in a username!'; 
} elseif(empty($_POST['votingsite']) && isset($_POST['submit'])){ 
    $funct_error = "Please select a voting site"; 
} elseif(isset($_POST['submit'])) { 
    $checksite = $mysqli->query("SELECT * FROM ".$prefix."vote WHERE id = ".$siteid.""); 
    $countchecksite = $checksite->num_rows; 
    if($countchecksite == 0 && isset($_POST['submit'])) { 
     $funct_error = "Invalid voting site."; 
    } else { 
     $result = $mysqli->query("SELECT *, SUM(times) as amount FROM ".$prefix."votingrecords WHERE NOT account='' AND NOT account='0' AND account='".$account."' AND siteid = '".$siteid."'") or die('Error - Could not look up vote record!'); 
     $row = $result->fetch_assoc(); 
     $sitequery = $mysqli->query("SELECT * FROM ".$prefix."vote WHERE id = '".$siteid."'"); 
     $vsite = $sitequery->fetch_assoc(); 
     $gvp = $vsite['gvp']; 
     $gnx = $vsite['gnx']; 
     $timecalc = $time - $row['date']; 
     if ($row['amount'] == '' || $timecalc > $vsite['waittime']) { 
      if($row['amount'] == '') { 
       $result = $mysqli->query("INSERT INTO ".$prefix."votingrecords (siteid, ip, account, date, times) VALUES ('".$siteid."', '".$ipaddress."', '".$account."', '".$time."', '1')") or die ('Error - Could not insert vote records!'); 
      } else { 
       $result = $mysqli->query("UPDATE ".$prefix."votingrecords SET siteid = '".$siteid."', ip='".$ipaddress."', account='".$account."', date='".$time."', times='1' WHERE account='".$account."' AND siteid = '".$siteid."'") or die ('Error - Could not update vote records!'); 
      } 
      $earnedpoints = true; 
      if ($earnedpoints == true) { 
       if ($account != '') { 
        $result = $mysqli->query("UPDATE accounts 
               SET $colvp = $colvp + $gvp, 
                $colnx = $colnx + $gnx 
               WHERE name='".$account."'") or die ('Error - Could not give rewards. Your site administrator needs to configure the NX and VP settings.'); 
       } 
       $funct_msg = '<meta http-equiv="refresh" content="0; url='.$vsite['link'].'">'; 
       $redirect = true; 
      } 
     } elseif($timecalc < $vsite['waittime'] && $row['amount'] != '') { 
      $funct_msg = 'You\'ve already voted for '.$vsite['name'].' within the last '.round($vsite['waittime']/3600).' hours!'; 
      $funct_msg .= '<br />Vote time: '. date('M d\, h:i A', $row['date']); 
     } else { 
      $funct_error = 'Unknown Error'; 
     } 
    } 
} 
if($redirect == true) { 
    echo $funct_msg; 
} else { 
    if(isset($funct_msg)) { 
     echo '<div class="alert alert-danger">'.$funct_msg.'</div>'; 
    } 
    if(isset($funct_error)) { 
     echo '<div class="alert alert-danger">'.$funct_error.'</div>'; 
    } 
    $query = $mysqli->query("SELECT * from ".$prefix."vote"); 
    if($query->num_rows == 0){ 
     echo "<div class=\"alert alert-danger\">Your administrator has not added any voting sites yet!</div>"; 
    } else { 
     echo " 
     <form method=\"post\"> 
     <div class=\"form-group\"> 
     <label for=\"voteSite\">Select Site:</label> 
     <select name=\"votingsite\" class=\"form-control\" id=\"voteSite\" required> 
     <option value=\"\" disabled selected>Select Site...</option>"; 
     while($row = $query->fetch_assoc()){ 
      echo "<option value=\"".$row['id']."\">".$row['name']."</option>"; 
     } 
     echo "</select> 
     </div>"; 
     if(!isset($_SESSION['id'])) { 
      echo "<input type=\"text\" name=\"name\" maxlength=\"15\" class=\"form-control\" placeholder=\"Username\" required autocomplete=\"off\"/><br/>"; 
     } else { 
      echo "<input type=\"text\" name=\"name\" maxlength=\"15\" class=\"form-control\" placeholder=\"".$_SESSION['name']."\" value=\"".$_SESSION['name']."\" required autocomplete=\"off\"/><br/>"; 
     } 
     echo " 
      <input type=\"submit\" name=\"submit\" value=\"Submit &raquo;\" class=\"btn btn-primary\"/> 
      </form>"; 
    } 
} 

私はSQLでvotingrecordsテーブルでこれを持っています。あたりです。

問題は、ユーザー名を入力してゲームに投票するたびに、「エラー - 投票記録を検索できませんでした」というエラーメッセージが表示されていることです。ここで

は、このエラーのコードです：

else { 
    $result = $mysqli->query("SELECT *, SUM(times) as amount 
           FROM ".$prefix."votingrecords 
           WHERE NOT account='' 
           AND NOT account='0' 
           AND account='".$account."' 
           AND siteid = '".$siteid."'") or die('Error - Could not look up vote record!'); 
    $row = $result->fetch_assoc(); 
    $sitequery = $mysqli->query("SELECT * FROM ".$prefix."vote WHERE id = '".$siteid."'"); 
    $vsite = $sitequery->fetch_assoc(); 
    $gvp = $vsite['gvp']; 
    $gnx = $vsite['gnx']; 
    $timecalc = $time - $row['date']; 

私はすべてを試みたし、それは助けるため

Answer 1

感謝を動作させることはできませんので、あなたたちは、私を助けることができると思います。 MYSQLでSET GLOBAL sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';を実行してこの問題を修正しました。 @RiggsFollyが本当に有用なエラーを表示するためにこのコードを使用するよう指示していない場合、これは起こりません。ありがとうございます。

ありがとうございます！
