应用错误收集

无法弄清楚出了什么问题。连接工作正常。我使用相同的connection.php文件来存储数据。但是不能以不同的形式预先填充。请帮忙。这是我写的代码：

<?php 
session_start();
if (!isset($_SESSION['email']))
    header('location: index.php');
?>
<!DOCTYPE html>
<html lang="en">
    <head>
        <title>Welcome</title>
    </head>
    <body>
<form  action="app_script.php" method="POST">
<input class="form-control" placeholder="Name" name="name" required = "true" value="<?php require_once("connection.php"); $eventid = $_GET['ID'];$field = $_GET['Name'];$result = mysql_query("SELECT $field FROM `persons` WHERE `ID` = '$eventid' ");$row = mysql_fetch_array($result);echo $row[$field]; ?>">
<button type="submit" name="submit" class="btn btn-primary pull-right">Submit</button>
                </form>
</body>
</html>

无法预先从表单中填充数据库中的数据
