stuck on ereg !!

[jwoo]

I have this code in my script

if (ereg("[^([0-9][a-f]{4})"."."."([^[0-9][a-f]{4})"."."."([^[0-9][a-f]{4})?$", $pmac))

It is checking if the variable $pmac is entered as a valid mac entry meaning xxxx.xxxx.xxxx so when a person enters xxxxxxxxxxxx the script executes the else statement. If its the properway xxxx.xxxx.xxxx the eregs lets it pass.

Dosent seem to work with that line i pasted from my script.

Help.

what is that?

you seem to have 3 unmatched [ in there, and I don't think you need any of them (always the ones followed by ^).

then, [0-9][a-f]{4} means 1 digit followed by 4 letters from a to f. I'd think you'd want 4 digits or letters instead, which would be [0-9a-f]{4}.

and you need to escape the dot to match it literally.

Yes you're right.. after your input I did some more digging on information and finally got this.

if (ereg("([0-9a-f]{4}).([0-9a-f]{4}).([0-9a-f]{4})", $pmac))

Works like a charm.

Thanks.

but don't forget to escape the dots ...

. - matches anything
. - matches a dot
