我正在处理一个项目，我希望通过使用复选框中的值更新表来为用户分配角色。我想使用复选框更新多个记录。我想从下拉菜单中选择用户时更新新服务表。我现阶段需要帮助。
#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>";
}
}
}

答案 0 :(得分：0)
这就是我所做的，如果你需要我解释它，只需发表评论。它只是在按下btn时检查所有检查的输入，然后它发出ajax请求并更新数据库中的值。我这样做了所以如果你检查了第四个输入，它将不会再次更新它，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");
?>
