[SOLVED] email fieldtype, checking for more than one email address with Regex

Hi
A while ago you showed me how to verify an email address in the email fieldtype, and it worked really well as follows:

Edit the email field in CB > Field Management and set "Authorized input:" to "Custom PERL regular expression" then set "Perl Regular Expression:" to "/^\w+@someuniversity.ac.uk$/" (without quotes). This will ensure the user can only register with an email address ending in @someuniversity.ac.uk.

Could you show me how I would add to that expression a second (or third) email address to verify against? e.g. @some-other-email.com

Separate multiple values with | it's basically the OR usage for REGEX. Example as follows.

/^\w+@(someuniversity.ac.uk|some-other-email.com)$/"

Thanks for that, with all this REGEX stuff I'm completely ignorant.

Is there somewhere on Joomlapolis where all these useful expressions have been collated, or a quick tips section of useful things to know like the key important links to the various CB, GJ, Subs, etc. components?

I know there would probably be loads of possible combinations, but the only way of finding them seems to be almost by accident after trawling through these forums.

Any chance of a quick reference chart somewhere?

Many thanks

REGEX is just a standard usage throughout several coding languages. You can learn about REGEX usage below.

www.regular-expressions.info/

Locations within CB and its plugins that support REGEX will directly state they do. I personally use RegexBuddy as it makes life significantly easier when writing REGEX.

Thanks for the tip and encouragement. I shall explore.

I think part of my problem with this might be more knowing what CAN be achieved rather than how. i.e. what other permutations could be applied to the various places I could apply REGEX within CB/GJ. I think that's what I mean about a quick reference page, a place that might contain some cool tips of what can be done, some of which I've come across (and forgotten about as they weren't relevant at the time) as I roam the Joomplapolis forum.

You're only limited by what REGEX is capable of doing so that's not really something we can measure or provide a guide for. If the area supports REGEX then all REGEX usages should work there. There's a lot of pre-done REGEX around the web too for really complex things. RegexBuddy also makes it incredibly easy to write and test your own REGEX.
