Question

I have a bit of a problem with my PHP code, I am assigning values to variables in different states of the flow depending on what I receive, but for some reason it keeps getting stuck at one point, here is the code.

if (isset($session)) {  
    //if the user is in the database
    if ($row == 1) {

        $from = $_GET['from'];

            if (isset($from)) { 

                $page = $_GET['page'];

                switch ($page) {
                    case "game":

                        $page = "game";
                        sendVars($page);//send the variable

                        break;
                    case "gallery":

                        $page = "gallery";
                        sendVars($page);//send the variable

                        break;
                    case "leaderboard":

                        $page = "leaderboard";
                        sendVars($page);//send the Variable                     
                        break;

                }
        }else {             
                $page = "game";

                sendVars($page);//send the variable
            }

        //if the user is not in the database
        }else {

            //do this
        }

} else {

    //register
}

Now for some odd reason, it keeps setting the value of $page to game, even though I set the page variable to gallery like so http://www.mydomai.com/?from=set&page=gallery . the only reason for this that I can think of is that my switch is not working as it should? or it is bypassing the switch somehow?

Thanx in advance!

Answer 1

I just ran your code after removing a few of the unessersary variable assignments:

<?php

// I added this function just for testing
function sendVars($page) {
  echo $page;
}

if (isset($_GET['from'])) {

  $page = $_GET['page'];

  switch ($page) {
    case "game":
      sendVars($page); //send the variable

      break;
    case "gallery":
      sendVars($page); //send the variable

      break;
    case "leaderboard":
      sendVars($page); //send the Variable
      break;
  }
} else {
  $page = "game";

  sendVars($page); //send the variable
}

And it all seems fine, xxx.php?from=1&page=gallery echos out “gallery”, try doing a print_r($_GET) at the top of your script and see what it prints out and let us know.

On a side note I think the below may be shorter for you and still do the same thing:

if (isset($_GET['from'])) {
  // Check if $_GET['page'] exsists and is either game, gallery or leaderboard
  if (isset($_GET['page']) && in_array($_GET['page'], array('game', 'gallery', 'leaderboard')))
    sendVars($_GET['page']);
}
else
  sendVars('game');

I hope this helps
