我正在制作一个api,可以帮助用户按照输入数据更新他们的信息.但是当输入json有字段"password"时它会成功更新但是当json没有这个字段时我无法更新数据库中的数据.这是我用来更新数据的代码:

public function updateUserInfo(Request $request){
        $postData = $request->all();
        $data = json_decode($postData['postData'], true);
        if(isset($data['password'])){
            $data['password'] = bcrypt($data['password']);
        }
        $popData = $data['UserId'];
        unset($data['UserId']);
        $updateInfo = array();
        foreach($data as $info){
            if($info != null){
                $updateInfo[] = $info;
            }
        }
        $result =  DB::update(GeneralFunctions::makeUpdateString($data, 'User', ' UserId = '.$popData), $updateInfo);
        if($result != null && $result == true){
            return response()->json(['success'=>true, 'data'=>'Update Successful']);
        }else{
            return response()->json(['success'=>false, 'error'=>'We have encountered an error, try again later!']);
        }
    }

当一切正常时,这是json:

$postData = '{ "UserId" : "1",   "password":"12345", "UserName": "minhkhang",  "Address": "11/200" …

我想用ajax或json将数据点添加到我的折线图中,现在我必须重新加载整个网页以在图表上显示我的新数据.但我想通过添加像这些链接的点来显示实时数据:

我试图从mysql中检索我的数据以通过json添加到图表上但没有任何反应.这是我在live-server-data.php中的代码:

<?php

header("Content-type: text/json");


 include_once 'include/connection.php';
 $db = new DB_Class(); 


     $query = "select distinct idchip from datatable ";
     $result = mysql_query( $query );
     $rows = array();
     $count = 0;

     while( $row = mysql_fetch_array( $result ) ) {
         $SQL1 =     "SELECT datetime,temperature FROM `datatable` WHERE idchip=".$row['0']." datetime DESC limit 0,1 ";

        $result1 = mysql_query($SQL1);

        while ($rows = mysql_fetch_array($result1)) {
           $data[] = $rows['1'];
           $datatime[] = 'moment('.$rows['0'].').valueOf()';
        }

        // The x value is the current JavaScript time, which is the …
