variable in a directory

[nadhim]

hello

 

i have a code to get some uploaded files from different folders

i have users and i want each user session ( the username ) get his file from the server

but simple thing here

 

how to use a variable like $session_user in a path

 

look at this code

 

$FileName = "test.php";
$fh = fopen('./premium/$FileName', 'w') or die("can't open file"); 

 

i got this from other site

 

but this doesnt work for me

i have the path inside a function see this

 

 

<?php

    protected $options;

    function __construct($options=null) {

in this code the important thing is the path to folder (12345)

 

            'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']).'/12345/',

 

this works perfect and get the data

 

 

 

bu now if i use for example

$path="/12345/";

 

 

how can i put his variable inside the path

like this

 

            'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']).'  '.$path.'  ',

 

this didn't work

 

how to get this variable inside this path ?

please help .

 

[rythemton]

Putting the directory name as a variable should work, as long as the directory actually exists. If each user will have a different directory for their files, then you need to either create the directory when the username is created, or check to see if the directory exists when a file is uploaded, and create it if the directory does not exist.

 

If the directory does exist but you still can't upload, then it may be a permissions issue.

[Pikachu2000]

'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']).'  '.$path.'  ',

 

Why are you adding all of those spaces before and after $path?

 

 

[nadhim]

I left spaces to show you its not this " 

;-)

[Pikachu2000]

Well, those spaces are probably why it doesn't work, and the added quoting isn't necessary.

 

'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']) . $path,

[nadhim]

I'll try this and give you the result

Thank you pro

[nadhim]

it didn't work the code posted by Pikachu2000 is good I'm sure

but where should i write the value $path in this document

i wrote it directly under

 

<? php

 

do i need a function or any thing else to identify $path

or its ok to write it anywhere ?

 

example :

 

$path="12345";

 

[nadhim]

i modified the code to write the slashes before and after file name like this

 

'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']) . "/"."12345"."/",

 

i did this because i thought the variable might not getting the slashes

 

this works fine but again when i identify 12345 as a variable in the top of the same document its not working

 

s.th like this

 

$path="123445";

 

 

the code should be

 

'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']) . "/".$path."/",

 

but its not working

 

why i have no idea

 

any help

First step to figure out why something is not working, is turning on error reporting. Then verify that the variables you're working with actually contains what you think they do, and if they do then begin to walk through the code step-by-step and/or reducing complexity.

At this point, it would probably be a good idea to also define exactly what 'not working' means.

hi problem solved

 

because the path inside a function and the variable definition outside  all i needed to do was adding (global) function to get the things to work like this

 

 

// this is the variable i want to use as a directory definition  
$logger=$login_session;
class UploadHandler
{
    protected $options;

    function __construct($options=null) {

// global function to allow the variable to work inside the function_construct
// use this with any function you wanted the variable to work in

global $logger;

        $this->options = array(

            'script_url' => $this->getFullUrl().'/',

// i used the variable as a folder path here and works fine 
            'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME'])."/account/".$logger."/",
