Question

我正在尝试根据日期（y-m-d）设置数据库中员工的状态。如果是两周前，并且他们设定了1周的限制来做某事，那么状态应该改变。我是这样做的：

$newsql = "update csvdata set status =:newstatus where statuschangedate < NOW() - INTERVAL :atf DAY AND username =:mem";
                $newgetcsvuser = $DBH->prepare($newsql);
                $newgetcsvuser->execute(array(':newstatus' => $newStatus, ':atf' => $memATF, ':mem' => $csvusername));

由于某些原因，当我运行它时，它将无法正常工作。对为什么不感到困惑？

因此，如果我在结尾处添加echo "working";，则会在我的页面上显示错误，内部错误。

以下是整个事情......

$date = date("Y-m-d"); 
$newStatus = "Non-Active - Driver Chose Non-Compliance";

    $sql = "SELECT username,ATF FROM members";
    $getcsvuser = $DBH->prepare($sql);
    $getcsvuser->execute();
    while($row = $getcsvuser->fetch(PDO::FETCH_ASSOC)){

        $memusername = $row['username'];
        $memATF = $row['ATF'];

        if ($memATF != 0 || $memATF != "0")
        {


        $tsql = "SELECT username,status,memberview ,statuschangedate,customernotes FROM csvdata WHERE memberview =:user";
        $tgetcsvuser = $DBH->prepare($tsql);
        $tgetcsvuser->execute(array(':user' => $memusername));
        while($trow = $tgetcsvuser->fetch(PDO::FETCH_ASSOC)){

            $csvstatus = $trow['status'];
            $csvusername = $trow['username'];
            $csvdate = $trow['statuschangedate'];
            if($csvstatus == "Open" || $csvstatus == "Enrolled - Policyholder Follow-Up Required" || $csvstatus == "Enrolled - Employee Follow-Up Required" || $csvstatus == "Non-Active - Insurance Cancelled" || $csvstatus == "Non-Active, Unable to Monitor - Incidental Business use Exclusion" || $csvstatus == "Non-Active - Employee Not Covered Under Listed Policy" || $csvstatus == "Non-Active - PolicyHolder Cancelled Additional Interest")
            {
                $notes = $trow['customernotes'];
                $notes = $csvstatus . " - ATF. " . $notes;

                $tsql="UPDATE csvdata SET customernotes=:notes =:date WHERE username=:tusername";
                $tsth=$DBH->prepare($tsql);
                $tsth->execute(array(':notes' => $notes,':tusername' => $csvusername));

                $newsql = "update csvdata set status =:newstatus where username =:mem and statuschangedate < DATE_SUB(NOW(), INTERVAL :atf DAYS)";
                //$newsql = sprintf('update csvdata set status =:newstatus where statuschangedate < NOW() - INTERVAL %d DAY AND username =:mem', $memATF);
                $newgetcsvuser = $DBH->prepare($newsql);
                $newgetcsvuser->execute(array(':newstatus' => $newStatus, ':atf' => $memATF, ':mem' => $csvusername));
                echo "working";
                $ynewsql = "update csvdata set statuschangedate =:date where username =:mem";
                $ynewgetcsvuser = $DBH->prepare($ynewsql);
                $ynewgetcsvuser->execute(array(':date' => $date, ':mem' => $csvusername));


            }


        }
        }

    }

Answer 1

如果我没记错的话，你就不能使用INTERVAL的参数..用PDO做的一天（虽然我可能会记错）。

如果是这样，您将不得不使用intval()或其他任何内容对其进行清理，并将其包含在原始SQL中。

e.g。使用sprintf('%d')进行清理以强制$memATF为整数：

$newsql = sprintf('update csvdata set status =:newstatus where statuschangedate < NOW() - INTERVAL %d DAY AND username =:mem', $memATF);

Answer 2

试试这个：

$newsql = "update csvdata set status =:newstatus where username =:mem and statuschangedate < DATE_SUB(NOW(), INTERVAL :atf DAYS)";

我会改变这一行:(因为这可能意味着$ memATF可能是NULL或字符串）

if ($memATF != 0 || $memATF != "0")

为：

$memATF = intval($memATF);
if ($memATF >0)

这将确保$ memATF必须是一个整数，如果整数大于zeo，代码将继续运行。

嘿伙计们我修理了它是因为：$tsql="UPDATE csvdata SET customernotes=:notes =:date WHERE username=:tusername";注意...:notes =:date....所以我刚拿出=:date并且它现在完美无缺：）
