email address check, allowing _

[danieloberg]

Can someone please edit:

if ( !eregi( "^{0-9a-z0-9a-z\.[a-z]{2,3}$",} $dinemail ) ) error( "Wrong." );

so it accepts the email address [e-mail] (name_ATdomain.com)?

Thanks!

There are about eleventy billion different ways to verify an e-mail address. My personal favorite is:

preg_match('/^{[-.\w]+@[-.\w]+.[\w]{2,4}$/',} $email);

[danieloberg]

Would it accept [e-mail]?
Nowadays, the letters é,å,ä,ö,ü etc are
accepted in .nu-domains, are they accepted
by this email check?

If I'm reading your regex right this email would fail

[e-mail]

You must not be reading it right then.. Try it 🙂

And to answer your quesiton about accented characters: no, it will not, but if you modify the code like this:

preg_match('/^{[-.\w\300-\377]+@[-.\w]+.+[\w]{2,4}$/',} $email);

It will.

Would

preg_match('/^{[-.\w\300-\377]+@[-.\w]+.+[\w\300-\377]{2,4}$/',} $email);

accept letters like é,å,ä,ö,ü in the domain name?

Thanks!

Right idea, wrong location. This is how it should look:

preg_match('/^{[-.\w\300-\377]+@[-.\w\300-\377]+.+[\w]{2,4}$/',} $email);
