PHP -创建和上传到目录
PHP -创建和上传到目录
提问于 2013-01-09 01:02:58
我正在尝试上传文件到一个用PHP创建的目录。应用程序应该根据用户的UserID在根目录中创建子目录。(例如，文件/14/)。
正在创建目录，但文件未上载到子目录。
代码如下：
<?php
include("dbConfig.php");
$Username = $_SESSION["username"];
global $userid;
$Password = $_SESSION["password"];
$Password = md5($Password);
$sql = "SELECT UserID FROM users WHERE Username = '".$Username."'";
$result = mysql_query($sql) or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
$userid = $row['UserID'];
}
echo $userid;
$dirname = (string)$userid;
$filename = ("/folder/" . "$dirname" . "/");
if (!file_exists($filename))
{
mkdir("files/$dirname", 0777);
if (isset($_FILES['files'])) {
echo "<div id='files_table'><table class='center'.><tr><td>";
$dest = ("files/" . $dirname . "{$_FILES['files']['name'][$key]}");
foreach($_FILES['files']['tmp_name'] as $key => $tmp_name){
move_uploaded_file($tmp_name, $dest );
echo $_FILES['files']['name'][$key], " uploaded.", "<br>";
}
}else {
if (isset($_FILES['files'])) {
echo "<div id='files_table'><table class='center'.><tr><td>";
$dest = ("files/" . $dirname . "{$_FILES['files']['name'][$key]}");
foreach($_FILES['files']['tmp_name'] as $key => $tmp_name){
move_uploaded_file($tmp_name, $dest );
echo $_FILES['files']['name'][$key], " uploaded.", "<br>";
}
echo "</td></tr></table></div><br><br>";
}
}
}

Brain，PHP支持一次上传一个文件，如果表单中有多个文件字段，应该在循环中保留"$dest = ("files/“.key.”{$_FILES‘FILES’$ $dirname }“)；”。在循环之外，$Key将为空。
循环不能在temp_name上，temp_name是php要上传的文件的临时副本。

修改后的代码如下：
注意:我也纠正了你代码中的一些错误。请进行比较。
<?php
include("dbConfig.php");
$Username = $_SESSION["username"];
global $userid;
$Password = $_SESSION["password"];
$Password = md5($Password);
$sql = "SELECT UserID FROM users WHERE Username = '".$Username."'";
$result = mysql_query($sql) or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
$userid = $row['UserID'];
}
$dirname = (string)$userid;
$filename = ("$dirname" . "/");
if (!file_exists($filename)) {
mkdir("files/$dirname", 0775);
}
if (isset($_FILES['files'])) {
echo "<div id='files_table'><table class='center'.><tr><td>";
foreach($_FILES['files']['tmp_name'] as $key => $tmp_name){
$dest = ("files/" . $dirname . "{$_FILES['files']['name'][$key]}");
move_uploaded_file($tmp_name, $dest );
echo $_FILES['files']['name'][$key], " uploaded.", "<br>";
}
} ?>
