【问题描述】：

我正在处理一个项目，我想通过使用复选框中的值更新表来为用户分配一个角色。我想使用复选框更新多条记录。当我从下拉菜单中选择用户时，我想更新 newservice 表。在这个阶段我需要帮助。

#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>";
              }

      }

【解决方案1】：

这就是我所做的，如果您需要我解释它，请发表评论。它只是在按下 btn 时检查所有检查过的输入，然后它发出一个 ajax 请求并更新数据库中的值。我这样做了，如果你检查了第四个输入的例子，它不会再次更新它，直到你刷新页面。

`<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>
`

up.php 在这里：

    <?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");
?>
