removing %20 from file names / images

[trimast]

Hi,

Part of a system if just set up allows users to upload files and images. Problem is the system is designed to be used by both adults and children, so we are having to make it a user friendly as possible.

Somebody has suggested that kids are likely to upload images with file names such as:

my%20image.gif
my images.gif

i've used the preg_replace php function to remove the whitespace, but am struggling to replace the %20 with an _ .

I'm sure its fairly simple so if anybody could help i'd be most grateful.

Thanks

Rob

hi!
This is the way i do it:

$userfile_name2 = str_replace('%20', '_', $userfile_name);

I had tried a variant of str_replace, but not as you had it.

Thanks, much appreciated.

%20 and alike are part of urlencoding.

$newname = preg_replace(' ','_',urldecode($name));

The actual solution is:

$userfile_name2 = str_replace('', '_', $userfile_name);

INSTEAD OF
$userfile_name2 = str_replace('%20', '_', $userfile_name);

in case the second doesnt work....

actually the '%20' option worked.

With a few alterations to another bit of code it works perfectly now!

Thanks to you all
