在MySQL中使用多維數組存儲$ _POST

Question

我有一個日歷，每天都有一個復選框，如下所示：

    <input type="hidden" name="uevent['.$urange.']['.$list_day.']['.$month.']['.$year.']" value="0"><input type="checkbox" id="calendarcheck" name="uevent['.$urange.']['.$list_day.']['.$month.']['.$year.']" checked>$list_day

其中$ urange是三種日歷中的一種。

單擊提交時，無論是否檢查，我都希望每天存儲在mysql中。 所以我生成了這段代碼：

    print_r($_POST);

    $big_query='INSERT INTO `sdcheckings` (`email`,`urange`,`cyear`,`cmonth`,`cday`,`dchecked`,`tcheck`) VALUES ';

    for($i=0;$i<count($_POST[$row[0]]);$i++)
    {
        for($j=0;$j<count($_POST[$row[0]][$i]);$j++)
        {
            for($k=0;$k<count($_POST[$row[0]][$i][$j]);$k++)
            {
                if($k!=0)
                    $big_query.=', ';
                $dchecked = $_POST[$row[0]][$i][$j][$k];
                $big_query.='('.$_SESSION['email'].',  '.$row[0].',  '.$i.',  '.$j.',  '.$k.', '.$dchecked.', CURRENT_TIMESTAMP) ';
            }
        }
    }
     $adddates = mysql_query($big_query);

當我通過檢查幾個日期（2016年2月4日和2016年2月12日）進行測試時，得到以下信息：

Array（[uevent] => Array（[1] => Array（[4] => Array（[02] => Array（[2016] => on））[3] => Array（[2016] => 0 ））[5] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[6] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[7] =>數組（[02] =>數組（[2016] => 0）[3] => Array（[2016] => 0））[8] => Array（[02] => Array（[2016] => 0）[3] => Array（[2016] => 0））[9] = > Array（[02] => Array（[2016] => 0）[3] => Array（[2016] => 0））[10] => Array（[02] => Array（[2016] = > 0）[3] =>數組（[2016] => 0））[11] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] = > 0））[12] =>數組（[02] =>數組（[2016] => on）[3] =>數組（[2016] => 0））[13] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[14] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[15] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[16 ] =>數組（[02] =>數組（[2016 ] => 0）[3] =>數組（[2016] => 0））[17] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016 ] => 0））[18] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[19] =>數組（[ 02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[20] =>數組（[02] =>數組（[2016] => 0）[ 3] =>數組（[2016] => 0））[21] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0）） [22] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[23] =>數組（[02] =>數組（ [2016] => 0）[3] =>數組（[2016] => 0））[24] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（ [2016] => 0））[25] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[26] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0））[27] =>數組（[02] =>數組（[2016] => 0 ）[3] =>數組（[2016] => 0））[28] =>數組（[02] =>數組（[2016] => 0）[3] =>數組（[2016] => 0 ））[29] =>數組（[02] =>數組（[201 6] => 0）[3] =>數組（[2016] => 0））[1] =>數組（[3] =>數組（[2016] => 0））[2] =>數組（ [3] =>數組（[2016] => 0））[3] =>數組（[3] =>數組（[2016] => 0））[30] =>數組（[3] =>數組（[2016] => 0））[31] =>數組（[3] =>數組（[2016] => 0）））））[提交] =>更新）

該數據庫未存儲任何內容。 我懷疑我的循環不正確。 那怎么辦？

在最后的$ big_query打印時，我得到的是：

INSERT INTO `sdcheckings` (`email`,`urange`,`gender`,`cyear`,`cmonth`,`cday`,`dchecked`,`tcheck`) VALUES

        foreach($_POST['uevent'][$row[0]] as $yearnum => $postyear)
        {
            foreach($postyear as $monthnum => $postmonth)
            {
                foreach($postmonth as $daynum => $postday)
                {
                    if($firstcoma>0)
                        $big_query.=', ';
                    $firstcoma++;

                    if(strcmp($postday,"on")==0)
                        $postday=1;

                    $big_query.='("'.$_SESSION['email'].'",  '.$row[0].',  "'.$row[1].'",  '.$yearnum.',  '.$monthnum.',  '.$daynum.', '.$postday.', CURRENT_TIMESTAMP) ';
                }
            }
        }
