Regular Expression Validation String in custom field

[thehost5968]

Hi

 

Can some one help me with Regular Expression Validation String in custom field for matching a Email Address as I have never used this before but once I have seen some code I should then be able to use it a lot.

 

Thanks

This page might help:

I'm not sure if they need to be put in a special way.

 

/^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/

 

seemed to help me with email, but:

 

/^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/

 

didn't with a URL.

 

I haven't figured out whether /^$/ have to be used to indicate start and end, and if a ; needs to be there at the end yet...
