passing php variables through header

Question

I want to pass a variable through header. In my system the user stays on the profile page and click on a link to fill and submit a form. When the form is submitted the page redirect to the profile page. When I the profile page displayed the member id has lost, so it don't display the member details. What I want to do is pass the member id when redirecting happens.

function redirect_to($location = NULL){
    if($location != NULL){
        header("Location:{$location}");
        exit;
    }
}


redirect_to('member_profile.php');

what I am trying to do is this

redirect_to('member_profile.php?id=$mselcted_memberI');

And why can't you do what you're trying to do? Did you try using " instead of '? — kero

You are using single quotes ' which will make it a literal string, instead, concatenate that using a . instead

redirect_to('member_profile.php?id='.$mselcted_memberI);

Also, you don't require braces {} here

header("Location:$location");

Braces make code more readable. I always use braces when placing vars into strings.

@Jari Depends, I only use them when dealing with arrays $var['blah']
