I saw one very good tutorial for pages here but...
thats my original sorce code for viewing tutorials and their categories:
[code]<?php
include 'connect.php';



//get the id, put it into a variable, cast to an INT

//(for security purposes)
if(!isset($_GET['page'])){
    $page = 1;
} else {
    $page = $_GET['page'];
}

// Define the number of results per page
$max_results = 1;

// Figure out the limit for the query based
// on the current page number.
$from = (($page * $max_results) - $max_results);
$id = (int)$_GET['id'];

$query = mysql_query("SELECT * FROM tutorials WHERE cat_id = '1' AND is_validated = '1' ORDER by id DESC LIMIT $from, $max_results ") or die(mysql_error());

//if no results, show that there are no tutorials

//for that category

if(mysql_num_rows($query) == 0)

{

echo "No tutorials for this category yet!";

}

//else, there is..show em

else

{

echo "<h1>Tutorials</h1>";

//loop through the tutorials

//show all tutorials

echo "<table border='0' cellpadding='0' cellspacing='0' width='500'>";

while($row = mysql_fetch_array($query))

?>[/code]

You can see my pages code.Because of the swich when in the adress bar is something like tuts.php?page=4
it just shopws me the tuts.php default
I want to create something like
tuts.php?viewcategory=2?page=5
and to show the right page in the right category,not the index.

I came up with that code:
[code]<?php
include 'connect.php';
include 'header.php';

switch($_GET['action'])

{
//get the id, put it into a variable, cast to an INT
default:
//(for security purposes)
if(!isset($_GET['page'])){
    $page = 1;
} else {
    $page = $_GET['page'];
}

// Define the number of results per page
$max_results = 3;

// Figure out the limit for the query based
// on the current page number.
$from = (($page * $max_results) - $max_results);
$id = (int)$_GET['id'];

$query = mysql_query("SELECT * FROM tutorials WHERE cat_id = '1' AND is_validated = '1' ORDER by id DESC LIMIT $from, $max_results ") or die(mysql_error());

//if no results, show that there are no tutorials

//for that category

if(mysql_num_rows($query) == 0)

{

echo "No tutorials for this category yet!";

}

//else, there is..show em

else

{

echo "<center><h1>Photoshop ефекти</h1></center>";

//loop through the tutorials

//show all tutorials

echo "<table border='0' cellpadding='0' cellspacing='0' width='500' align='center'>";

while($row = mysql_fetch_array($query))
