Question

我正在尝试制作一个用于mp3上传的PHP脚本，但是我想使用用户会话$ _SESSION [username]创建一个不存在的上传文件夹。在文件夹mp3 /中，当我在命令行运行时我没有出现任何错误，但是当我尝试上载mp3时，它每次都会失败，并且不会创建该文件夹。

<?php 


session_start();

if (isset      ($_SESSION ['band_id'  ]))
{
    $band_id  = $_SESSION ['band_id'  ];
    $bandname = $_SESSION ['bandname' ];
    $username = $_SESSION ['username' ];
}

// set database connection

require("connect.php");



// lets get our posts //
$song     = $_FILES['song_name'];
// folder that will hold songs
$songpath = '/mp3/' . $_SESSION['username'];

// song-file pathname
$songpath .= $song['name'];

if (!file_exists($songpath)) {
    mkdir($songpath."/".$_SESSION['username'], "/" ,0777,true);
}

var_dump($songpath);

// move the file from the tmp folder to the song folder
if (move_uploaded_file ($song['tmp_name'], $songpath))
{
    print "<p>Upload succeeded thank you</p>\n";
}
else
{
    print "<p>Upload failed, sorry</p>\n";
}

print <<<END
<p>
To continue, <a href="index.php">click here.</a>
</p>
</body>
</html>
END;

?>

Answer 1

您使用的目录路径错误。

使用此：

// lets get our posts //
$song     = $_FILES['song_name'];
// folder that will hold songs
$songdir = '/mp3/' . $_SESSION['username'] . '/';

// song-file pathname
$songpath = $songdir . $song['name'];

if (!file_exists($songdir)) {
    mkdir($songdir, 0777, true);
}

Answer 2

检查phpinfo（）; 什么是tmp目录？还要检查max_file_size并检查所有路由的用户权限

Answer 3

所以我能够使用代码，并在朋友的一点帮助下使其工作谢谢的Oldcoder。简而言之，我必须给出绝对路径，如果没有，请检查mp3文件夹是否存在，然后检查用户是否有一个文件夹/ mp3 / user 似乎工作得很好:)

<?php




session_start();

if (isset      ($_SESSION ['band_id'  ]))
{
    $band_id  = $_SESSION ['band_id'  ];
    $bandname = $_SESSION ['bandname' ];
    $username = $_SESSION ['username' ];
}

// set database connection

require("connect.php");



// lets get our posts //
$song     = $_FILES["song_file"]["name"];
// Main MP3-files directory
$mp3dir   = '/var/www/ympradio.com/public_html/mp3';

// Create it, if necessary
if (!file_exists ($mp3)) {
    mkdir ($mp3dir, 0777, true);
}

// Folder that will hold user's files
$songdir = $mp3dir . '/' . $_SESSION ['username'];

// Create it, if necessary
if (!file_exists ($songdir)) {
    mkdir ($songdir, 0777, true);
}

// Song-file pathname
$songpath = $songdir . '/' . $song;

var_dump($songpath);

$songtemp = $_FILES["song_file"]["tmp_name"];

// move the file from the tmp folder to the song folder
if (move_uploaded_file ($songtemp, $songpath))
{
    print "<p>Upload succeeded thank you</p>\n";
}
else
{
    print "<p>Upload failed, sorry</p>\n";
    print "<p>($mp3dir) ($songdir) ($songpath)</p>";
}

print <<<END
<p>
To continue, <a href="index.php">click here.</a>
</p>
</body>
</html>
END;

?>

使用php检查文件夹是否存在（如果不对文件上传脚本进行复制）
