Question

i’m trying to make an image appearance and disappearance based on 3 condition,

condition A = when user is logged in and it’s username fits the displayname(by using the GET function) then it should echo “yes”

condition B = When user is logged in and it’s username does not fits the displayname then it should echo “no”

condition C = when user is not logged in then it should echo “no” too

(i swapped the image with yes and no for easier referencing)

By logging in, the user has a cookie which is set like below

  setcookie("user", $user, $expire);
  setcookie("loggedin", 1, $expire);

First i get the cookie which i set when user logins.

  $user1 = $_COOKIE["user"];
  $loggedin = $_COOKIE['loggedin'];
  $user = strtoupper($user1);

then i get my player’s name

  $playername = $_GET['player'];

Now i do the conditions

$uplayername = strtoupper($playername);

function showplusicon(){

    global $uplayername;

    if(($loggedin = "1") and ($user == $uplayername)){
        echo "yes";
    }
    else if (($loggedin = "1") and ($user != $uplayername)){
        echo "no";
    }
    else{
        echo "no";
    }
}

I don’t see what’s the problem but it keeps being registered as condition B.

Answer 1

The variable $loggedin isn’t known inside your function showplusicon(). You will need to add it as a global along with global $uplayername.

function showplusicon(){

   global $loggedin, $uplayername;

   // etc
}

Since this was accepted but not totally complete, I’ll just add that as others indicated, the == equality operator needs to be used instead of the = assignment operator.

if(($loggedin == "1")
