Question

我是PHP的新手，我正在学习Headfirst PHP和MySQL的书。

我已经制作了一个HTML表单，因此用户可以上传文件（在本例中是一个图像文件）。这是代码：

<?php
define('GW_UPLOADPATH', 'guitar/images/');

if(isset($_POST['submit'])) {

    $name = $_POST['name'];
    $score = $_POST['score'];
    $screenshot = $_FILES['screenshot']['name'];

    if(!empty($name) && !empty($score) && !empty($screenshot)) {

        $target = GW_UPLOADPATH . $screenshot;

        if(move_uploaded_file($_FILES['screenshot']['tmp_name'], $target)) {
            $dbc = mysqli_connect('localhost', 'root', '', 'guitar')
            or die('Error connecting to MySQL server');

            $query = "INSERT INTO guitarwars VALUES (0, '$name', '$score', NOW(), '$screenshot')";

            $result = mysqli_query($dbc, $query) or die('Error querying database.');

            echo '<p>Thanks for adding your new high score!</p>';
            echo '<p><strong>Name:</strong> ' . $name . '<br />';
            echo '<strong>Score:</strong> ' . $score . '</p>';
            echo '<img src="' . GW_UPLOADPATH . $screenshot . '" alt="Score image" /></p>';
            echo '<p><a href="index.php">&lt;&lt; Back to high scores</a></p>';

            $name = "";
            $score = "";
            $screenshot = "";

            mysqli_close($dbc);
        }else{
            echo '<p class="error">Sorry, there was a problem uploading your screen shot image.</p>';
        }

    }else{
        echo '<p class="error">Please enter all of the information to add ' .
            'your high score.</p>';
    }
}
?>

当我把index.php＆amp;服务器根文件夹中的images文件夹一切正常。

但是当我在htdocs文件夹（服务器根文件夹）中创建目录（在本例中为：guitar文件夹）并将项目文件放在该目录中时，问题就出现了。

问题是，当用户上传图像文件时，它不会转到图像文件夹，并显示此错误：

Warning: move_uploaded_file(guitar/images/jacobsscore.gif): failed to open stream: No such file or directory in C:\xampp\htdocs\guitar\addscore.php on line 35

Warning: move_uploaded_file(): Unable to move 'C:\xampp\tmp\phpE3BE.tmp' to 'guitar/images/jacobsscore.gif' in C:\xampp\htdocs\guitar\addscore.php on line 35

无法使用PHP
