page.php?something

hunkyjack

When browsing the net you can't help noticing how many people use a mypage.php?mycontent style navigation, and it looks extremley useful. However, unfortunatley I haven't got a clue how to do this. Could anyone point me in the direction of a tutorialm or (if it's simple) explain how it might work in this case...

I would like it to work for a game link. Basically if they choose 'Space Invaders' it will go to play.php?space, but if they choose 'Stan Skates' it will go to play.php?stan and display the game depending on what is after the ?. I thought maybe you might use cases, and have something like

<?php
case (stan$) {
game$=1
}
?>

etc. and then later on in the php when calling the game put in <?game$?> (making game$ a global)

Can anyone give me any hints on how to make this dream a reality?

Thanks

Matt

Just make the links on the main page to look like

play.php?game=stan
play.php?game=space
play.php?game=whatever

<?php
switch ($_GET['game']) { 
	case "stan": 

	header( "Location: games/stan.php" );
	break;

case "space": 

	header( "Location: games/space.php" );
	break;

case "whatever": 

	header( "Location: games/whatever.php" );
	break;

} 
?>

Thats one way to do it...

Thanks, but that still relies on me having more than one page, and I was trying to keep it to a minimum. Would it work if I changed it to

case "stan" {

game$ = 'stan.swf'

}

I'm not sure about .swf files, but give it a shot. And if those are php variables, the dollar sign goes in the front, as in $this is a variable.

$name
$address

etc.
good luck!

Ok i made this simple code first (I haven't put in the .swf extensions unless they stop it working) but the link will not change when i out in play.php?game=stan

<?php
global $game;
switch ($_GET['game']) {

case "space":
$game = 'space';
break;
case "stank":
$game = 'stan';
break;
}
?>

<html>

<head>

</head>

</html>

Does anyone know where I've gone wrong????

I'm gettin to know PHP as well, but the link is pointing to a variable. I believe you need to add the $game to a link:

<?php 
global $game; 
switch ($_GET['game']) { 
case "space": 
$game = 'space'; 
break; 
case "stank": 
$game = 'stan'; 
break; 
} 
?> 

<html> 

<head> 

</head> 

<body> 
<a href="<? [url]http://www.yoursite.com/gamepage.php?game=[/url]$game; ?>">Link</a>
</body> 

</html>

And then have the swf be loaded. Someone can help you, I gotta go. 🙂

Hi hunkyjack,
For a start, I would check out http://hotwired.lycos.com/webmonkey/01/48/index2a_page6.html?tw=programming as this is where I got hold of this info! It's really very good. Anyway, the way that the variables are pinned onto the URL is by a normal HTML form.
This would look something like this:-

<HTML>
<HEAD><Title>Game Form</Title></HEAD>
</HEAD>
<BODY>
<Form Method=Get Action="play.php">
What game would you like to play?<BR>
<Select Name="game">
<Option Value=stan>Stan
<Option Value=space>Space
<Option Value=whatever>Whatever
</Select>
<BR>
<Input Type=Submit Value="Play the Game!!!"
</Form>
</BODY>

This little file will create a pull-down menu with the name "game". The important factor here is the 'Method=Get'. This pins the variable onto the end of the URL instead of hiding it (as would happen if Method=Post). If you were writing this in PHP, you could even use $PHP_SELF to 'get' it from itself. In this instance, the URL would look like: www.whateveryourdomainis.com/play.php?game=stan Inside your PHP file, you could refer to $game as a normal variable. This means that you could check:
if($game==stan){
echo "<Applet Code=stan.class width=300 height=250>"
}
if($game==space){
echo "<Applet Code=space.class,etc>"
}

I hope this helps you out anyway.🙂

Whoa... my post didn't come out at all... parsed the URL.

This makes no output.

It must read

If $game is "stan" the output will be <a href="stan">Link</a></body>. If you want the output to read something else, change the HTML that you're using as a template.

The "=$game;" is shorthand for "echo $game;" and you occasionally will see it in short tags embedded in HTML.

Ok, thats all working now. My only problem now is how to make it output if there is no ?game=wateva after play.php

I thought you could just put in }else{ but that doesn't work. Does anyone know how I can do it?

What is the current code that you are using?

hunkyjack

<?
global $game;
global $name;
if($game==stan){
$game = 'flash/stan_skates.swf';
$name = 'Stan Skates';
}
if($game==space){
$game = 'flash/space_invaders.swf';
$name = 'Space Invaders';
}
?>

laserlight

try something along these lines:

<?php
if (isset($_GET['game'])) {
	switch ($_GET['game']) {
	case 'stan':
		$game = 'flash/stan_skates.swf';
		$name = 'Stan Skates';
		break;
	case 'space':
		$game = 'flash/space_invaders.swf';
		$name = 'Space Invaders';
		break;
	default:
		//error message that game is invalid
		//may want to use die() if necessary
	}
	//whatever processing done with $game and $name
}
else {
	//show whatever is default (i.e. no ?game=something)
}
?>
