當我使用php pdo檢查複選框時，如何更新多個記錄？

我正在處理一個項目，我想通過使用複選框中的值更新表來爲用戶分配一個角色。我想用複選框更新多個記錄。我想從下拉菜單中選擇用戶時更新新的服務表。在這個階段我需要幫助。當我使用php pdo檢查複選框時，如何更新多個記錄？

#assign estimator 
     $gp = $userDetails->pgroup; 
     $users = $db->prepare('SELECT 
     dbo.[GWCL$west_users].name AS fullname, 
     dbo.[GWCL$west_users].user_group AS pgroup, 
     dbo.[GWCL$west_users].username, 
     dbo.[GWCL$west_users].uid, 
     dbo.[GWCL$west_users].region, 
     dbo.[GWCL$west_users].district 

     FROM dbo.[GWCL$west_users] 
     WHERE 
     dbo.[GWCL$west_users].user_group = 10 
     '); 
     $users->execute(); 



     #update and assign estimating officer 

     if($_POST['process']){ 

      foreach($_POST['dm_approve'] as $id) 
      { 



       $update =$db->prepare('UPDATE dbo.[GWCL$NewServiceConnection] SET dbo.[GWCL$NewServiceConnection].staffID = '.$_POST['staffID'].', dbo.[GWCL$NewServiceConnection].dm_approve = 1 WHERE dbo.[GWCL$NewServiceConnection].Application_ID ='.$id.''); 
       $update->execute(); 
      $result = $update->rowCount(); 
     if ($result ===false) { 
       echo "Failed"; 
       }else{ 
       echo "Status " .$id. " is assigned to ".$_POST['staffID'].". <br>"; 
       }

這就是我所做的，如果你需要我解釋它只是留下評論。它只是在btn按下時檢查所有檢查過的輸入，然後它發出ajax請求，並更新數據庫中的值。我做到了，所以如果你檢查exmaple第四個輸入，它不會再更新它，直到你刷新頁面。

`<html> 
<head> 

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script> 
    <script> 
    var arr=[]; 

function send() 
{ 
var neww=[]; 
    //get all of the inputs that are checked 
$("input[type=checkbox]").each(function (input){ 


    if ($(this).is(":checked")==true) 
    { 
    if (arr.indexOf($(this).attr('value'))<0) 
    { 
     arr.push($(this).attr('value')); 
     neww.push($(this).attr('value')); 
    } 
    } 


}) 
var string = JSON.stringify(neww); 
$.ajax({ 
type:"GET", 
url:"up.php", 
dataType:"json", 
data:{"values": string}, 
success: function (res) 
{ 
    //do what u want when this complete 
} 
}) 
} 
    </script> 
</head> 
<body> 


<input type="checkbox" id="check1" value="1">1</input><br> 
<input type="checkbox" id="check2" value="2">2</input><br> 
<input type="checkbox" id="check3" value="3">3</input><br> 
<input type="checkbox" id="check4" value="4">4</input><br> 

<input type="button" onclick="send()" value="Click me"></input> 

</body> 
</html> 
`

和up.php是在這裏：

<?php 
$yes = array(); 
$string=json_decode($_GET["values"]); 

//db connect 
$con = new mysqli("localhost","yourusername","yourpass","yourdb"); 

foreach ($string as $val) { 

$sql="INSERT INTO yourtabel Values ('',{$val})"; 
$con->query($sql); 
} 
//echo json_encode("bv"); 
?>
