Match...	Can't Post

I'm trying to match the filename for a 'file' sype field. The format of the variable is;

C:\WINDOWS\Desktop\wee\contact-button.gif

I'm trying to grab the contact-button.gif.

I currently have;

$IN->param('TestImage') =~ m,(.+?)\.(gif|jpg|jpeg)^, and $img = $1;

The problem is, that is not grabbing anything :|

I have aslo tried;

$IN->param('TestImage') =~ m,\\(.+?)^, and $img = $1;

Anyone got any suggestions?

Cheers

Andy

Ok...here is a test script;

Code

#!C:\Program Files\nusphere\perl\bin\perl.exe 
# ================================================================== 
 
$var = "c:\windows\test\test.gif"; 
$var2 = "c:/windows/test/test.gif"; 
 
$var  =~ m|([^\\]+)$| and $img = $1;  
$var2 =~ m|([^/]+)$| and $img2 = $1; 
 
print "Content-type: text/html \n\n"; 
print "\$img => $img <BR><BR>\$img2 => $img2";

This returns;

$img => c:windows est est.gif

$img2 => test.gif

Anyone got any ideas? It seems to be the backslaslashes that are causing the problem :(

Cheers

Well your first post examples are wrong because you are using ^ at the end of the regex when you should be using $

Your next post seems wrong because I get a different result for your code.

Code

$var = "c:\windows\test\test.gif";  
$var  =~ m|([^\\]+)$| and $img = $1;

For me $img now contains "test.gif"

The following works fine...

Code

my ($in)   = $IN->param('file_field'); 
my ($file) = $in =~ m|([^\\/]+)$|;

LOL....just worked out why my Regex was givng the wrong result.

To define the file, I was using;

$var = "c:\windows\test\test.gif";

I forgot that the \ would be escaping the 'w', 't' and 't' Unimpressed

All seems fine now that I am quoting it with ' '.

Cheers
