每天只有一次用戶限制表格提交

我正在努力爲人力資源管理系統開發出勤表格。我想限制每個註冊用戶每天提交一次。第二天，我的意思是在上午12點之後，用戶將再次提交表單。我怎樣才能做到這一點使用PHP或有什麼辦法？日期將被自動插入，但時間被用戶插入。這是我的表單代碼：每天只有一次用戶限制表格提交

<?php 

        if($_POST) 
        { 
         date_default_timezone_set('Asia/Dhaka'); 
         $timein = mysql_real_escape_string($_POST["timein"]); 
         $timeout = mysql_real_escape_string($_POST["timeout"]); 
         $date = date("d, F Y"); 
         $workinghours = abs($timein-$timeout); 


           $res = mysql_query("INSERT INTO timeclock SET usr='".$uid."', timein='".$timein."', timeout='".$timeout."', date='".$date."', workinghours='".$workinghours."'"); 
           if($res){ 
            echo "<div class=\"alert alert-success alert-dismissable\"> 
           <button type=\"button\" class=\"close\" data-dismiss=\"alert\" aria-hidden=\"true\">&times;</button>  

           Successfully! 

           </div>"; 

           } 
           else{ 
            echo "<div class=\"alert alert-danger alert-dismissable\"> 
           <button type=\"button\" class=\"close\" data-dismiss=\"alert\" aria-hidden=\"true\">&times;</button>  

           Some Problem Occurs, Please Try Again. 

           </div>"; 
           } 

        } 
        ?>

可能是它的工作：

<?php 

        if($_POST) 
        { 
         date_default_timezone_set('Asia/Dhaka'); 
         $timein = mysql_real_escape_string($_POST["timein"]); 
         $timeout = mysql_real_escape_string($_POST["timeout"]); 
         $date = date("d, F Y"); 
         $workinghours = abs($timein-$timeout); 

         $nnn = mysql_fetch_array(mysql_query("SELECT COUNT(*) FROM timeclock WHERE usr='".$uid."' and date='".$date."'")); 
         if($nnn[0]>="1"){ 
          echo "<div class=\"alert alert-danger alert-dismissable\"> 
           <button type=\"button\" class=\"close\" data-dismiss=\"alert\" aria-hidden=\"true\">&times;</button>  

           Today Already Added, Please Try Again Tomorrow. 

           </div>"; 
         } 
         else 
         { 
           $res = mysql_query("INSERT INTO timeclock SET usr='".$uid."', timein='".$timein."', timeout='".$timeout."', date='".$date."', workinghours='".$workinghours."'"); 
           if($res){ 
            echo "<div class=\"alert alert-success alert-dismissable\"> 
           <button type=\"button\" class=\"close\" data-dismiss=\"alert\" aria-hidden=\"true\">&times;</button>  

           Successfully! 

           </div>"; 

           } 
           else{ 
            echo "<div class=\"alert alert-danger alert-dismissable\"> 
           <button type=\"button\" class=\"close\" data-dismiss=\"alert\" aria-hidden=\"true\">&times;</button>
