php - 文件上传/mkdir() 问题

Question

我正在尝试创建一个相当简单的（理论上）文件上传“过程”。我浏览了该网站，虽然有一些我需要的片段，但似乎没有任何效果！

基本上，我正在尝试创建一个处理如下的函数：

1. 获取文件扩展名
2. 获取文件名
3. 组合文件名、clientID 和扩展名
4. 检查目标目录是否存在。如果没有，请创建它。
5. 将文件（以新名称）移动到目录中

我的文件结构如下：

• 根
  • 行政
    • 上传
      • 客户端上传
        • $客户ID

这是我所拥有的：

 <?php
 include("dbconnect.php");

 error_reporting(-1); // ALL messages and 
 ini_set('display_errors', 'On');

 if($_GET['clientID']){

 //This function separates the extension from the rest of the file name and returns it 
 function findexts ($filename) 
 { 
 $filename = strtolower($filename) ; 
 $exts = split("[/\\.]", $filename) ; 
 $n = count($exts)-1; 
 $exts = $exts[$n]; 
 return $exts; 
 } 

 //Get filename function
 $filename = "test"; //I dont know how to create this function at the moment
 return $filename;

 //This applies the function to our file  
 $ext = findexts ($_FILES['uploaded']['name']) ; 

 // we will be using the clientID as the new folder and adding it into the filename
 $clientID = mysql_real_escape_string((int)$_GET['clientID']);

 //merge filename
 $filename2 = $filename."_".$clientID.".";

 //Scan for existing directory
 $folder = '../admin/uploads/client_uploads/'.$username.'/';
 if (is_dir("$folder") == false) {
 mkdir("$folder", 0777);    
 echo "Directory created";
 } 


 //This assigns the subdirectory you want to save into... make sure it exists!
 $target = "admin/client_uploads/$clientID";

 //This combines the directory, the random file name, and the extension
 $target = $target . $filename2.$ext; 

 //Move file under new name 

 if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
 {
 echo "The file has been uploaded as ".$filename2.$ext;
 } 
 else
 {
 echo "Sorry, there was a problem uploading your file.";
 }
}
?>

我没有收到任何错误消息（尽管我已经明确要求它们）并且我最终得到一个空白屏幕。文件夹没有在我的服务器上的任何地方创建，也没有任何反应。

有任何想法吗？提前致谢。

试试这个，

<?php
//get file name in your own way 
$filename   =   $_FILES["filename"]["name"];
$fLength    =   strlen($filename);
$exParts    =   explode(".",$filename);
$totalParts =   count($exParts);
$extension  =   $exParts[$totalParts-1];
$eLength    =   strlen($extension);
$filename   =   substr($filename,0,($fLength-$eLength+1));
//Get the client ID as you need
$client_ID  =   //client ID here;
$up_file_name   =   $filename."_".$client_ID.".".$extension;
$folder     = $_SERVER['DOCUMENT_ROOT']."/admin/uploads/client_uploads/".$username."/";

if(!is_dir($folder))
{
//Create directory
$parts  = explode("/",$folder);
for($j=0; $j<count($parts); $j++)
{
$fpath    = "";
for($k=0; $k<=$j; $k++)
{
$fpath  .=  $parts[$k]."/";
}
if(!is_dir($fpath))
{
$oldmask=umask(0);
mkdir($fpath,0755);
umask($oldmask);
}
}
}
//Upload your file
$pathtoupload   =   $folder.$up_file_name;
if(move_uploaded_file($_FILES["filename"]["tmp_name"],$pathtoupload))
{
echo "Uploaded successfully";
}
else
{
echo "Can't upload";
}
?>

Answer 2

在双引号中使用使用过的 $folder。删除它并使用

 //Scan for existing directory
 $folder = '../admin/uploads/client_uploads/'.$username.'/';
 if (is_dir($folder) == false) {
 mkdir($folder, 0777);    
 echo "Directory created";
 }

我认为你必须在服务器中设置写入权限......并且需要一个一个创建目录......试试这个......

$parts  = explode("/",$folder);
for($j=0; $j<count($parts); $j++)
{
  $fpath    = "";
  for($k=0; $k<=$j; $k++)
  {
    $fpath  .=  $parts[$k]."/";
  }
  if(!is_dir($fpath))
  {
    $oldmask=umask(0);
    mkdir($fpath,0755);
    umask($oldmask);
  }
}
