Question

我正在尝试使用pdo来更新数据库，代码没有返回任何错误，但代码不起作用。逻辑是用户输入用户ID，然后新位置点击提交，位置将更新。

以下是表单代码：

<html>
    <head>
        <title>Web Dev 1</title>
    </head>
    <body>
        <form method="post" action="update.php">
            Patient location by ID: <input type="text" id="Patid" name="Patid" /><br />
            Location: <input type="text" id="Location" name="Location" /><br />
            <input type="submit" name = 'action' value="update" />
</html>

这是更新代码：

<?php
    error_reporting(E_ALL);
    ini_set('display_errors',1);
    $host = "localhost";
    $user ="sbuser";
    $db = "mdb";
    $pass ="lamepassword";
    $conn = new PDO($dsn, $user, $password);
    $sqlInsert = 'UPDATE lobby set Location=:Location where Patid=:Patid';
    $preparedStatement = $conn->prepare($sqlInsert);
    $preparedStatement->execute(array(':Patid' => '$_POST[Patid]', ':Location' = $_POST[Location]' );
    }
?>

您的代码中存在一些错误

<?php
 $host = "localhost";
 $db = "mdb";
 $user ="sbuser";
 $pass ="";
 $Patid=$_POST['Patid'];
 $Location=$_POST['Location'];
 $conn = new PDO("mysql:host=$host;name=$name",$user,$pass);
    $sqlInsert = "UPDATE lobby SET Location=? WHERE Patid=?";
    $preparedStatement = $conn->prepare($sqlInsert);
    $preparedStatement->execute(array($Location, $Patid));
?>

php表单没有更新数据库
