[RESOLVED] setting default $var?

[pmnjason]

hello all!
been trying for the last few days to get this script running how i want, but to no avail.

basically i need to know how to set a variable if one doesn't carry over.

like i have email2 set through a link, carried over, and it sends through $headers .= "BCC: $email2"; in my script. but if i don't have it defined in the link, it crashes.

is there a way in the php file i can set it that if a variable isn't assigned to set it as a default email, like "[e-mail]" or better yet, just not send a bcc?

thanks for any help!

Yes. Check to see if the variable has a value using a conditional with [man]empty()[/man].

if( !empty($email2) ) {
    $headers .= "BCC: $email2";
}

[pmnjason]

right on!

so that checks to see if $email2 has a value, and if it does, then that adds to the header?

so i don't need to include the bcc in the headers at all using this technique? and it just wont send with one? but if there is an email set then it'll add the bcc script on to the header?

just making sure i understand.

thanks so much!

If [man]empty/man returns false (which is negated to true, by the '!'), then data is appended onto the end of the $headers variable.
