I have a page where the user enters an email address. What code would I use to make sure the email address is in a valid format? I don't need to verify it. I just want to make sure they enter something like abc@abc.com. If they don't then I want them to receive an error about the email not being valid and to go back and enter a valid one.< |

Thanks, again, Huw; will add that to the script when I get back on the other machine.

sorry, another tweak, this should be much better
[A-Z0-9!#$%*/?|\^{}`~&'+-=_]*@\w+([-.]\w+)*\.\w+([-.]\w+)*< |

actually mine needs a slight adjustment
\w*([!#$%*/?|\^{}`~&'+-=_])*\w*@\w+([-.]\w+)*\.\w+([-.]\w+)*
it was not allowing this address a!#$%&'*+-/=?@example.com which believe it or not is perfectly valid.
there are still a few cases that won't validate, but they would be very unusual.< |

Yes, Shaggy, I guess that was the one.< |

Thanks, Huw; have replaced the RegEx with your one. Looks like this was the source of your one, Rui - some interesting, over-the-top alternatives in that article.

I haven't had problems. I got it from a book or online and I remember that it stated that a couple "obscure" cases weren't contemplated. I can't remember what cases were not contemplated, but they were not relevant enough to justify a much more complex regex.< |

here is better one , the one posted above does not accept all the valid characters for an email address, the one below should.
\w+([!#$%*/?|^{}`~&'+-=_]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*< |

No problem . This is not a complete solution, even if it should be fine for "normal" use.< |

I currently do not have access to my forum files, but following Huwrs input, would this work:
if EmailField(frommail) = 0 then strError = strError & "Enter an e-mail address in the form username@domain.co.uk<br></font>"
...
..
end if (later)
I have gone for the =0 as all the other error messages have a link underneath to return to input form.< |

The function should replace the existing EmailField function in inc_func_member.asp so you will also need to include inc_func_member.asp
you would then use it like so
if EmailField(frommail) = 1 then
'we passed so do stuff :)
else
'we failed so error
end if< |
