I'm trying to get this line to validate an email address from a form and it
isn't working.

if (ereg("^.+@.+\..+$",$submittedEmail))



The book I'm referencing has this line

if (ereg("^.+@.+\\..+$",$submittedEmail))



Anyway.. I welcome any advice as long as it doesn't morph into a political
debate on ADA standards and poverty in Africa. :-)



Thanks



Don

That would reject many of my email addresses. This is more in line with
the standards:

Hope it works out for you.

Don't top-post.
Trim quoted material.
Use a mail user agent that doesn't screw up quoting. There's a plugin
for Outlook to fix it.
Thanks.

I should have also mentioned that the function is fundamentally flawed,
and the whole section dealing with deliverability should be removed.
The only way to reliably find out about an email address deliverability
is to send it a secret and receive it back (filtering out bounces).
This mathematician, Daniel Bernstein, has a proof-of-concept code in
ezmlm. (Or just google for VERP.)

What's "Top Ajax"?

I already have a regular expression that matches a reasonable subset of
the grammar defined in RFC 822. Why should I use someone else's square
wheel when I have mine own?

Also, if there are many email validators with better code, please offer
those better ones if you must.

1. Why did you remove the backslash? (the original was correct)
2. What do you expect the regexp to match?
3. Define "it isn't working".

> Try this : http://www.weberdev.com/get_example-3274.html

This will reject addresses that use greylisting, and 600 lines
in a single function is gross. I wouldn't touch that.

I have a regular expression tester plugin in firefox and it validates Ok
with the expression he provided.

If I add the second (original) backslash it won't validate emails anymore.

Also, from my little knowledge of Red.Exp. the backslash will escape special
chars.
In this case the backslash will escape the dot to match only a dot and not
all chars...

This my way of seing it...

hi...

the real problem you have with email validation is that the vast majority of
the email validation scripts that you see in various apps only handle a part
of what the wc3/spec states to be valid email addresses.

if your app had the ability to handle the time constraint, a reasonable
approach would be to simply fire off a msg to the email address and check
the return status code! if you're really going to try to get a function to
validate email addresses, and you're concerned about the outlying address
types, then you're going to wind up with an ugly/hairy/complex situation.

awhile ago, in taking the path least traveled, i punted this issue, and used
a 'perl' function that i call from php to handle it... does it take a little
longer, sure... but i decided it was worth it....


peace..

This will reject addresses that use greylisting, and 600 lines
in a single function is gross. I wouldn't touch that.

You can always go to http://www.weberdev.com/ and write "email validation"
in the Top Ajax search box. There are many other email validators that
should have less than 600 lines in one function

Top Ajax :
I meant that at the top of WeberDev.com there is an Ajax search box that you
can use
to search for "email validation" and see many related code examples to
choose from.
