email validation

[Anon]

So I am trying to validate email addresses before submitting them to a database. I pass the variable $email to my action script. Here is the code I have so far:

if (isset($email))

return (ereg('^{[-!#$%&\'+\./0-9=?A-Za-z{|}~]+'. '@'. '[-!#$%&\'*+\\/0-9=?A-Z^_a-z{|}~]+.'} . '[-!#$%&\'*+\./0-9=?A-Z`a-z{|}~]+$', $email));

localConnect();

MySQL_query("insert into table_1(field1, field2) values ('$email', '$value');");

Now I know this is incorrect, what am I supposed to do with the return(ereg(..) code so that it returns a value based on the $email variable? Any help will be much appreciated.

ereg returns either true or false.. use it within a conditional statement such as an if/else..

if (ereg('^{[-!#$%&\'+\./0-9=?A-Za-z{|}~]+'. '@'. '[-!#$%&\'*+\\/0-9=?A-Z^_a-z{|}~]+.'} . '[-!#$%&\'+\./0-9=?A-Z`a-z{|}~]+$', $email)) {
// this means ereg evaluated true, and they have a valid email
return $email;
} else {
return 0;

---

then, you say when you call the function..

if ( !validate_email() ) { // this executes when we have an invalid email
echo "You have specified an invalid email, please go back and try again.";
exit;
}

hope this could help,
