Problem with dynamic paths

Expand Post »

I'm trying to use some dynamic path names for an image upload page. In a tutorial they had something like this:

PHP Syntax (Toggle Plain Text)
<?PHP
 
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']); 
 
// this echoes something like " /foldername/ " presumbing that the php file is set inside that folder in the root.
 
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploaded_files/'; 
 
// this echoes something like this "C:/folder/subfolder//foldername/uploaded_files/"
 
?>
<?PHP

$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']); 

// this echoes something like " /foldername/ " presumbing that the php file is set inside that folder in the root.

$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploaded_files/'; 

// this echoes something like this "C:/folder/subfolder//foldername/uploaded_files/"

?>

basicly when you put the two strings togheter to create the path, in this case for a temporary directory to store uploaded files, each string has an "/" at the end and beginning... so when you link them you get "...subfolder//foldername..."

Is there any way to force any of the above commands not to display one of the "/" or to somehow eliminate it in order for the path to be valid?

Re: Problem with dynamic paths

You could use str_replace function to replace "//" with "/".

php Syntax (Toggle Plain Text)
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploaded_files/'; 
$uploadsDirectory = str_replace("//","/",$uploadsDirectory);
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploaded_files/'; 
$uploadsDirectory = str_replace("//","/",$uploadsDirectory);

There are many other ways of fixing the problem. str_replace just seems the easiest to me.

Re: Problem with dynamic paths

thank you for the suggestion... but it turns out that it dosen't need it... despite the fact that echoing the patch and copy pasting that in a browser dosen't work... it seems that php is somehow able to interpret it properly and the code works even with "//" in it... I have no idea how but oh well...

Re: Problem with dynamic paths

Maybe this will work as well... ??????

php Syntax (Toggle Plain Text)
$uploadsDirectory = dirname(__FILE__) . '/uploaded_files/';
$uploadsDirectory = dirname(__FILE__) . '/uploaded_files/';
