id-based navigation system

BlackWing02

Hi peeps.

I've been trying to make this kind of navi system..
but i don't know why it doesn't work.
I'm just starting to learn php, by the way..

here is the code that will work as an iframe:

<?
switch($id)
{
default:
include("home.html");
break;
case "links":
include("links.html");
break;
case "tuts":
include("tutorials.html");
}
?>

^ this would be activated by this:
<a href="?id=links">Links</a>
<a href="?id=tuts">Tutorials</a>

here's the problem...
undefined variable id
but it still does the default action from the switch

but when i define the id variable, it always load the defined value..

plus.. the links doesn't work. it only performs the default action..

i'm using IIS.

Thanks in advance. 🙂

Hi,
try to start with this
if(!isset($id))$id="defpage";

And another tip:
default: as first voice of switch is not a good idea. Put at end.


if(!isset($id))$id="defpage";

switch($id) 
{ 
case "links": include("links.html"); 
    break; 
case "tuts": include("tutorials.html"); 
    break; 
default: include("home.html"); 
} 
?> 

<a href="?id=links">Links</a> 
<a href="?id=tuts">Tutorials</a>

Thanks, bad76. 😃

Nyways, good news is that it doesn't return an undefined error anymore. But, it still loads the default action and doesn't recognized the href values..

what else can i do? 🙁

But you don't want to load the default?!? I've misunderstand...
Just add any dummy entry in case.
For href put the name of script itself.

<?if(!isset($id))$id="defpage"; 

switch($id)  

{  

case "defpage": break;
case "links": include("links.html");  

    break;  

case "tuts": include("tutorials.html");  

    break; 
default: include("home.html");  

}  

?>  

<a href="<?=$PHP_SELF?>?id=links">Links</a> 
<a href="<?=$PHP_SELF?>?id=tuts">Tutorials</a>

I just didn't want the default action to be done even when I click the links.

I added the

<?=$PHP_SELF?>

But the browser returns a 404 error..

I'm really sorry if I can't get this...

bad76

Use the name of your file instead <?=$PHP_SELF?>:

If this file is called "index.php" rewrite this:

<a href="index.php?id=links">Links</a>
<a href="index.php?id=tuts">Tutorials</a>

It still loads the default only.

Do you think the problem is in my IIS?

i cant pass any variable values to other pages too..

pls tell me why.

BlackWing02

sori. need to ask this again.

isn't it possible to pass values to other php scripts in other pages?

Hi,
i think it not possible, PHP don't access to frame.
You have to use PHP to write a javascript that set var in another frame.

But what is actual state? I havent looked your previous post...

Any hint: if possible try to use this some like this...

<?
if(!isset($id)) $id="index.php";  

include($id);
?>   

<a href="index.php?id=links.html">Links</a> 
<a href="index.php?id=tutorials.html">Tutorials</a>

May be this will work.

The default is still the one always recognized..

Do you think it's possible to pass the variables as references? Because it doesn't recognize the passed values..

Thanks again for your time
