Question

我有一个从数据库加载值的组合框。我想当用户从组合框中选择值时，表单应该将相应的值从数据库加载到html表单中。这是我正在尝试的代码：

<!DOCTYPE html>
<html>
<head>
<title>Obracun plata</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<link href="layout.css" rel="stylesheet" type="text/css" media="screen" />
</head>
<body>
<?php
error_reporting(0);
mysql_connect("localhost", "root", "");
mysql_select_db("zaposleni");
    $query = "SELECT * FROM radnici;";
$rezultat = mysql_query($query);
?>

<div id="wrapper">
  <div id="logo">
<h1>Obračun plata</h1>
<p>Income calculator</p>
  </div>
  <div id="menu">
<ul>
<li><a href="index.html">Pocetna</a></li>
  <li><a href="podaci_o_radnicima.php" class="active">Podaci o radnicima</a>                       </li>
  <li><a href="spisak_radnih_mjesta.php">Spisak radnih mjesta</a></li>
  <li><a href="obracun.php">Obracun</a></li>
  <li><a href="spisak_gradova.php">Spisak gradova</a></li>
  <li><a href="spisak_mjeseci.php">Spisak mjeseci</a></li>
    </ul>
  </div>
  <div id="page">
  <div id="content">

<br/>
  <td>Radnici:</td>
<td>
<select name="Radnik">
<?php
error_reporting(0);
mysql_connect("localhost", "root", "");
mysql_select_db("zaposleni");
    $query = "SELECT * FROM radnici;";
$rezultat = mysql_query($query);
for($data = mysql_fetch_row($rezultat); $data != null; $data =         mysql_fetch_row($rezultat))
    echo "<option value='" . $data[0] . "'>" . $data[1] . " " . $data[2];
?>
</select>

if($_POST["Radnik"] == "")

$rezultat2 = mysql_query($query2);
$rezultat3 = mysql_query($query3);

$data1 = mysql_fetch_row($rezultat1);
