Question

我正在尝试创建一个人们可以提交内容的网站。用户可以查看当月已提交的次数以及仍可以完成的提交次数。我想要的是，当本月达到提交限制时，网站应该阻止本月的任何提交。我怎么知道它只会阻止这几个月的未来提交？我仍然希望人们能够在其他月份提交。

date_default_timezone_set('UTC');

$currentDate = date("m");
$currentDate2 = date("F");
$maxSubmissions = '7';
$monthChecker[] = array();

$monthQuery = "SELECT * FROM submissions
           WHERE MONTH(dateRelease)= '$currentDate' ";

if($result = $db->query($monthQuery)) {

//Count amount of reservations of current month and show them
$teller = $result->num_rows;
if($teller == $maxSubmissions){
    //The limit has been reached
    $monthChecker['limit'] = "Het reserveringslimiet voor " . $currentDate . " is al bereikt.  ";
    if($teller > $maxSubmissions){
    // I think that i should write something here, but I have no idea what...
    }
} else{
    // the limit has not yet been reacherd
    $monthChecker['nolimit'] = "Er is in " . $currentDate2 . " al ".$teller." keer gereserveerd";
}


} else {

//if error
die("mysqli error: " . mysqli_error($db));
}

如果您尝试将每个用户限制为每月仅提交7次，则需要减少该userId返回的设置。例如，如果您的提交表还包含userId，您可以添加以下和子句：

$monthQuery = "SELECT * FROM submissions
       WHERE MONTH(dateRelease)= '$currentDate' 
           AND userId = $userId";

如果此数据是关系数据，则可能需要使用联接。

此处您可能还有次要问题，因为上述内容将专门针对MONTH。如果提交表上没有清理机制，您最终可能会提前影响当前年度的提交。

如何在提交一定时间后阻止未来的提交？
