Question

我有以下代码上传文件：

<?php
//set the image size in mb
$max_upload_size='10';
$MAXIMUM_FILESIZE = $max_upload_size * 1024 * 1024;
get_current_user();
global $current_user;
$uploaddir = './uploads/file/'.$current_user->user_login.'/'; 
$file = $uploaddir . basename($_FILES['uploadfile']['name']); 
if ($_FILES['uploadfile']['size']<$MAXIMUM_FILESIZE) {
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], $file)) { 
  echo "success"; 
} else {
    echo "error";
}
}else{
    echo"size_error";
}
?>

如果user_login已存在于/ uploads / file /目录下，则此方法很有用。如果不存在，我如何创建基于变量$ current_user-＆gt; user_login的目录？如果存在，则继续下一个代码。

来自http://nz.php.net/manual/en/function.move-uploaded-file.php#105026：

目标目录必须存在; move_uploaded_file（）不会自动为你创建它。

只需使用is_dir和mkdir。

<?php
//set the image size in mb
$max_upload_size='10';
$MAXIMUM_FILESIZE = $max_upload_size * 1024 * 1024;
global $current_user;
$current_user = get_current_user();
$uploaddir = './uploads/file/'.$current_user->user_login.'/';
if (!is_dir($uploaddir) && !mkdir($uploaddir)){
  die("Error creating folder $uploaddir");
}
$file = $uploaddir . basename($_FILES['uploadfile']['name']); 
if ($_FILES['uploadfile']['size']<$MAXIMUM_FILESIZE) {
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], $file)) { 
  echo "success"; 
} else {
    echo "error";
}
}else{
    echo"size_error";
}
?>

  <?php
//set the image size in mb
$max_upload_size='10';
$MAXIMUM_FILESIZE = $max_upload_size * 1024 * 1024;
get_current_user();
global $current_user;
if(!is_dir('./uploads/file/'.$current_user->user_login))
{
   mkdir('./uploads/file/'.$current_user->user_login);
}
$uploaddir = './uploads/file/'.$current_user->user_login.'/'; 
$file = $uploaddir . basename($_FILES['uploadfile']['name']); 
if ($_FILES['uploadfile']['size']<$MAXIMUM_FILESIZE) {
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], $file)) { 
  echo "success"; 
} else {
    echo "error";
}
}else{
    echo"size_error";
}
    ?>

或者在$ updloaddir初始化之后，在is_dir()和mkdir()中添加带有$ uploaddir参数的if语句。

创建目录，如果不存在，则移动文件
