Regex for file extension

Hi All,

My customer has asked to validate the file extension supported by Browse field with case insensitive file extensions.

I have used the following regex - "^.+\.((jpg)|(gif)|(jpeg))$; however it is not accepting the extns as JPG or GIF.

Any pointer or suggestion to accept all case extns like GIF, Gif, giF, gif.

Thanks.

If it is just about upper/lowercase:

[PHP] /\.ext/i [/PHP]

This i at the end makes the regex case-INsensitive.

I'm not sure if it will work - but try something like this:

"(?i)\.(jpg|gif|jpeg)$"

If that doesn't work - you're stuck doing:

"\.(jpg|JPG|gif|GIF|jpeg|JPEG)$"

Ugly - but it works...

"(?i)\.(jpg|gif|jpeg)$"

YOU ROCK!!!
