[PHP] Question refering to URL Processing

[AC_Drkan]

Im trying to take a url like this:

Code Select Expand


www.clan-n2o.com/index.php?view=Console&action=StatsChecker&user=Me


using a switch statement i was able to parse the data correctly but then i came to and question:

How would i check to see whether user has a value?
Here is my code (so far):

Code Select Expand


switch ($view) {
case "Console":
switch($action) {
case "StatsChecker":
switch($user) {
case "";  // ?? user has a value? <-- problem here
break;
default:
StatsCheck();
break;
}
break;
                }
}


Ideas:

Code Select Expand


switch ($view) {
case "Console":
switch($action) {
case "StatsChecker":
switch($user) {
case isset($user);  // would this work?
break;
default:
StatsCheck();
break;
}
break;
                }
}

Your first code snippet should work, I'd use the die() function though in that case though assuming you want the script to stop if $user doesn't have a value.

I would use a check like:

Code Select Expand

if(isset($user) or $user == "") {
die("Error: No user specified.");
} else {
StatsCheck();
}

But is there any way to use a switch statement?

like this:

Code Select Expand


case "Console":
switch($action) {
case "StatsChecker":
switch($user) {
case isset($user):
switch ($game) {
            case isset($game):
              getstats($user, $game);
              break;
          default:
                                StatsCheck-Enter();
                                break;
                      }
                      break;
default:
StatsCheck-Enter();
break;
}
break;
// Next Case goes here
}
break;


Reason is im writing a complete Clan Script off of 1 file and i wanted to fully parse the url.

Rather than having intensively-loaded switch conditions within other switch conditions, you should subdivide into smaller functions, for instance:

Code Select Expand


case "Console":
   testConsole($action);
   break;
case "Something":
   testSomething($action);
   break;


// later
function testConsole($action) {
  switch ($action) {
    // blah
  }
}


That makes debugging easier and code maintenance MUCH easier.

isset will not accomplish what you want because even if user===''; isset($user) will still return true.  isset returns false only if user=== NULL; || unset($user); 

what you might try to do is this, if you can use if's:

Code Select Expand



switch($_GET['user'])
     case isset($_GET['user']):
          if($_GET['user']==='')
                echo 'You didn\'t enter a username.';
          else{
                 echo $_GET['user'].' was entered as a username.'
          }
     default:
          echo 'Either you are trying to access this page directly, or your login was not correctly parsed.  Please attempt to re-loggin.  Thankyou.';

Ok thy on that subject.

Now i got another:

i cannot set a cookie in php,
i know the code, and my clan scripts are running fine. but for some odd reason
this:

Code Select Expand


if (isset($_COOKIE['visit'])) {
$lastvisit = $visit;
echo("<p align=\"center\"><FONT FACE=\"Tahoma\" SIZE=\"1\" COLOR=\"#FFFFFF\">Hello Again there your last visit to this site was on $lastvisit.</p>");
} else {
setcookie("visit", date( "D M d, Y H:i:s \G\M\T\."), time() + 3600);
echo("<p align=\"center\"><FONT FACE=\"Tahoma\" SIZE=\"1\" COLOR=\"#FFFFFF\">Hello and Welcome To This Clan, This is your first visit to thes site today!</p>");
}


does absolutely nothing,
I have looked at every php manual that i can think of and it says that this code would be correct but for some weird reason, it will not output:

Code Select Expand


Hello Again there your last visit to this site was on $lastvisit.

line 2
$lastvisit = $_COOKIE['visit'];

cookies can not be set after anything has been outputted to the screen.  This includes echo commands and even the <html> tag.  Be sure to set your cookies at the top of every page.
