Question

我想从mysql中获取数据。我是seeng值（Poraba），但不是类别。有人帮我吗？我没有尝试json打印，但我认为这是必要的。

php代码：

<?php

   session_start();

    session_regenerate_id();

   include("db_connection.php");


   if(!(isset($_SESSION['username'], $_SESSION['login_string']) || isset($_COOKIE['username']))){

      header("Location: index.html");
      exit();
   }

   $username = $_SESSION['username'];

   $rezultat = "SELECT vrednost, kategorija FROM vrednosti WHERE username = '$username'";

   $result = mysqli_query($link, $rezultat);

   if (mysqli_num_rows($result) > 0) {

    while($row = mysqli_fetch_assoc($result)) {
        echo "" . $row["kategorija"]. "\t" . $row["vrednost"].  "\n";
    }
      } else {
      echo "Še ni zapisov";
   }  

      mysqli_close($link);
?>

查询给出了正确的值：

“Kurjava 34 Kredit 200 Trgovina 45 Tehnika 54 Vrtec 200”

<body>

<div id="container" style="width: 100%; height: 400px; margin: 0 auto"></div>

我认为，这个错误在于工具提示formmater函数，但我不知道如何替换它。
