Question

过去5个小时我遇到了一些问题。我一直在努力解决它，我似乎无法找到解决方案，所以我希望你能帮助我！

所以我有这个vote.php脚本：

<?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>";
    }
}

我在SQL中的votingrecords表中有这个：ip, account, date, times, amount。这是对的。

我遇到的问题是每当我输入用户名来投票时，我都会收到此错误消息“错误 - 无法查看投票记录！”。

以下是此错误的代码：

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'];

我希望你们可以帮助我，因为我已经尝试了所有的东西而无法让它工作

感谢您的帮助。我通过在MYSQL中执行此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';来解决此问题。如果@RiggsFolly没有告诉我使用此代码显示真正有用的错误，就不会发生这种情况，谢谢。

全部谢谢！
