You can't put code inside the curlies {} in a string.
I'm not sure I understand exactly what you are wanting to do, but if you
want to print a line break if the value is set, or do something else if
it is not, then you probably want to do it like this:
if(isset($_POST['name'])) {
// do something
}
else {
// do something else
}
If you want to assign the value to a variable you can do it like this:
$string = isset($_POST['name']) ? $_POST['name'] : "something else";
With this example, if $_POST['name'] is set then $string will be
populated with that value. If it's not then it will be populated with
"something else".
