Hey I have the follow email validation expression
^[\w-.]+@([\w-]+.)+[\w-]{2,4}$
What I am looking for is for email addresses to be allowed which have a "+" before the @ part of the email cheers
+1
A:
Just change it to ^[\w-.]+(?:\+[\w]*)?@([\w-]+.)+[\w-]{2,4}$
This allows for + before @ and some characters which is optional. So [email protected] [email protected] are both valid.
Updated.

Stevie, can you ask the question with a bit more info? Similar to this question which you gave good examples.

Yeah I would like to allow a phone number such as +00(49) 87956325412 at the moment my validation only allows numbers ^[+\d ]+$

Try this: ^\+?\(001\)|(00\(\d\d)\)\s*\d{8,12}$

Make sure you have no space after the telephone. I am using Expresso and your example works,.

I tried the following

<code><asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server" ValidationExpression="^\+?(001)|(00(\d\d))\s*\d{8,12}$" ControlToValidate="txtPhone" Display="None" EnableClientScript="false" ErrorMessage="Please provide valid phone number."> </asp:RegularExpressionValidator></code> and phone number +00(49) 87956325412. And it fails the validator i.e it thinks it is an invalid number

Use Expresso http://www.ultrapico.com/Expresso.htm and see if it works in there. If so, make a new question and put the link here so that I can check it up.

A:
Or use a full RFC 822 regex
^((?>[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+\x20*|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*"\x20*)*(?<angle><))?((?!\.)(?>\.?[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+)+|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*")@(((?!-)[a-zA-Z\d\-]+(?<!-)\.)+[a-zA-Z]{2,}|\[(((?(?<!\[)\.)(25[0-5]|2[0-4]\d|[01]?\d?\d)){4}|[a-zA-Z\d\-]*[a-zA-Z\d]:((?=[\x01-\x7f])[^\\\[\]]|\\[\x01-\x7f])+)\])(?(angle)>)$
And the RegexLib is great place for finding regex for most requirements, you are rarely the first to want to do something.
