PHP Question

[Zenax]

Ok, I need some help on a little bit of PHP code.

I got the code so that I can create the ids for each page e.g. index.php?id=1

How would I go about modifying the code so I could get: index.php?id=1&category=2

or something along those lines?

The code I have for the current index page is as follows:

<?php 


if( isset($HTTP_GET_VARS['id']) || isset($HTTP_POST_VARS['id']) )
{
    $id = ( isset($HTTP_GET_VARS['id']) ) ? $HTTP_GET_VARS['id'] : $HTTP_POST_VARS['id'];
    $id = htmlspecialchars($id);
}
else 
{
    $id = "";
}

switch( $id )
    {   
            // ?id=1          This leads to section 1   
         case "1":
        include("inc/1.php");
       break;
        
            // ?id=2           This leads to section 2
         case "2":
        include("inc/2.php");
       break;    
       
       // The default page to load, when website is started.
       default:
       include("inc/main.php"); 
       break;


}

?>

obviously I have changed it to match the scenario above, just to make it simpler.

How would I go about changing this code so that it would allow: index.php?id=1&category=2

Your help is very muchly appreciated!

Just a little note: $HTTP_GET_VARS = $_GET

just add the code $_GET["category"] (or $HTTP_GET_VARS["category"] ) where you wanna get category number. It can be freely put in included files, because included files source is added to php code when parsing.

Hmm I am slightly confused? do I just repeat the code at the top at the bottom of the page, but change it to the different name?

Totally confused

actually, you can put code (about category's) inside the included files, because all variables in first code (index.php, etc...) are also in included files.

example for a news system:

index.php?id=news&category=5 is opened by browser / user
index.php finds id, and so knows what page to include
index.php includes news.php
news.php looks for category
news.php finds category because category's number was defined in URL
news.php loads news from category...
and etc....

Point of this: If you have file included, included files can use same resources as the file that includes.

Don't ask me to explain again, because i will paint it then.

Sorry I am a bit of a noob when it comes to PHP. I got it to work though, thank you!

There is a much better way to do this:

<?
if (isset($_GET['id']) && file_exists('./pages/'.$_GET[id].'.php')) {
include './pages/'.$_GET[id].'.php';
} else {
include("pages/About.php");
}
?>

All of your files except for the index.php would go in the folder pages which on the server is /public_html/pages/

and your links would be

<a href="index.php?id=news">News</a> <a href="index.php?id=about">About</a> <a href="index.php?id=contact">Contact</a>

do this

//////////////   index.php
<?php
if( isset($HTTP_GET_VARS['id']) || isset($HTTP_POST_VARS['id']) )
{
    $id = ( isset($HTTP_GET_VARS['id']) ) ? $HTTP_GET_VARS['id'] : $HTTP_POST_VARS['id'];
    $id = htmlspecialchars($id);
}
else 
{
    $id = "";
}

switch( $id )
    {   
            // ?id=1          This leads to section 1   
         case "1":
        include("inc/1.php");
       break;
        
            // ?id=2           This leads to section 2
         case "2":
        include("inc/2.php");
       break;    
       
       // The default page to load, when website is started.
       default:
       include("inc/main.php"); 
       break;


}
?>

////////////////    1.php
<?php
if (isset($_GET['category']) && file_exists('./category1/'.$_GET[category].'.php')) {
include './category1/'.$_GET[category].'.php';
} else {
echo "select category";
} 
?>
////////////////    2.php
<?php
if (isset($_GET['category']) && file_exists('./category2/'.$_GET[category].'.php')) {
include './category2/'.$_GET[category].'.php';
} else {
echo "select category";
} 
?>
