If and else function

[Anon]

This for me doesnt work:

if ($repeat="") {
$repeat=$newsid;
} else {
$repeat=$repeat;
}

what i want to do in english...

if the number $repeat="" then i want $repeat to then be the number thats in $newsid
otherwise, i dont want to change it.

Whats wrong with that? as when executed, it prints nothing that comes after it (as i have print code after it)

Is it the "=" that im trying to use? if it is, how else can i do it?

Try ($repeat == "")

Yup, that works fine!

Thanks!

or you can just do:

if (!$repeat) {$repeat = $newsid;}

an empty variable returns false
also you don't need the "else" part
