Regular Expressions - help needed!

[moongirl129]

Hi there I am involved in running a membership based website which allows users to enter a certain amount of 'free' text. However to make the system work they should not be able to enter an email address. We have a Function already which uses regular expressions to look for email addresses using standard formats but unfortunately a lot of users are getting wise to this and changing theoir address slightly to trick the system. For instance they might enter one of the following:

myname@mycompany.co.uk

OR

m y n a m e @ m y c o m p a n y . c o . u k

OR

myname(at)mycompany(dot)co(dot)uk

And these do indeed escape our check!!

Can anyone point me in the write direction on how to get round this, or does anyone know of a component or something that is available to use?

Thanks.

I would just check for the @ sign and do some sort of notification on that criteria. If the @ is contained in the text then the entire text gets booted. Chaging the regex to find the @ should be basic if the function is already in place to match the @ .com

either that or add the .co.uk and or you can use a function to trim all the spaces from the text to test for matches.
and I gues you could even match d @ f d . c o m if you wanted, but getting rid of the spaces would be easier.

possibly post the function if you want us to take a look and try and give you some direction on changing to check for these things A language that doesn't affect the way you think about programming is not worth knowing.

I think Moongirl is saying that people can put (at) in their text. You can never completely rule out all deviations of anything, if there is a way around something then somebody will find it. The best you can really do is rule out the obvious and leave the rest to chance. Saturday 12.00
