There are alot of sites out there with the index.php as the main page right? (Namely all of them) However when some coders create sites, they create separate entitites and pages with a ?page=4 modifier, or whatever page they want it to be.

I don't know how to do that, because each page is 'based' off of the index.php page, when I find an example, i'll post it here, but Does anyone know how to do this?

Like I said, this is hard to explain, so when I get an example, I"ll post it here.

it's easy:

First you must get this variable:

CODE

<?php
if ( isset($HTTP_GET_VARS['page']))
{
$ID = strval($HTTP_GET_VARS['page']);
}
?>

Next you can use this $ID to chose what page load. In the simple way, using "if, else if"

CODE

<?php
if ($ID == 1)
{
include("some_page.php");
}
else if ($ID == 2)
{
include("some_page2.php");
}
else
{
include("bad_page.php");

}
?>

There is many others way to use this kind variables, from content whole page to content one ceil in table

Omgz I love you both - Panda for asking the question, and you palladin for answering it. I've been looking for that for ages to paginate my stories so I don't run into page after page of documents.

Here's a way using arrays:

CODE

<?

$page = $_GET['page'];

$i = array(
1 => 'page1.html',
2 => 'page2.html',
3 => 'page3.html'
);

if (isset($page)){
include($i["$page"]);
}

?>

This looks more organized to me. Works the same as palladin's way.

CODE

<?
$val = $_GET['id']; // Replace id with whatever you want to use, eg ?id=page
$val .= ".php"; // Makes the filename complete so if you called ?id=index, it would be index.php it has to look for
$dirty = array("..");
$clean = array("");
$val = str_replace($dirty, $clean, $val); // Prevent people from viewing root files like your password (should work i just quikly added it without testing)

if (isset($_GET['id'])) { // Replace id with whatever you want to use, eg ?id=page
if (file_exists($val)) { // This checks if the file you are trying to call exists
include "$val";
}
else {
include "404.php"; // If the file doesnt exists it calls your 404 error page
}
}
else {
include "news.php"; // If ?id= is not set it will now go to your news page
}

// Include this script in your content area
// Run ?id=pagename (without .php) to view a page
?>

CODE

?page=something

So I guess this is what they call a query string?! I've been trying to figure this one out as well.

Palladin:
I'm guessing ID is a variable that you can easily change the value of? Can I use a link for this one e.g. if I want to do ID=2 can I just do this (see code below)?
[CODE]<a href="?ID=2">switch to new page</a>

Yea but i make small mistake

Better write what evry line do for future use.

CODE

<a href="?ID=2">switch to new page</a>

| HTML | this is call index.php?ID=2

CODE

if ( isset($HTTP_GET_VARS['ID']) == TRUE) { CODE }

| PHP | this is check is variable ID are use as argument in page adress

CODE

$ID = intval($HTTP_GET_VARS['ID']);

| PHP | this assign value from HTTP variables (using in adress) to $ID php integer variable for future use. (ID=1)

CODE

$ID = strval($HTTP_GET_VARS['ID']);

| PHP | this assign value from HTTP variables (using in adress) to $ID php string variable for future use. (ID=news)

thats all

you can use rvovk example too:

Using check only is variable are called:

http://page.com/index.php?news

CODE

if ( isset($HTTP_GET_VARS['news']) == TRUE) { include("news.php")}

http://page.com/index.php?music

CODE

if ( isset($HTTP_GET_VARS['music']) == TRUE) { include("music.php")}

There are many ways to achieve such urls, i personally love them but havent completely figured out the much tougher function based php

I will show you a function i use for News, the authorization that is..:

CODE

Function AuthAddNews() {
Global $user,$uid, $admin, $aid, $db;
if((!isset($admin)) || (!isset($user))){
Header("Location: index.php");
die();
}
$db->"SELECT * FROM ".$prefix."_permission where userid="".$uid." OR adminid="".$aid."";
$result = query();
$permission = mysql_fetch_rows($result);
if($permission[p_admin]=!1){
if($permission[p_user]=!1){
$permission = false;
$id = "anonymous";
}
} else {
If(isset($admin)){
$id = $aid;
}
if(isset($user)){
$id = $uid;
} else {
die();
}
$permission = true;
}
Header("Location: index.php?act=news&permission=".$permission."&id=".$id."");
}

It's quite simple, first on the frontpage i had a link called News and the link was:
index.php?act=news
you just write it.
this should open the news() function (wich should obviously have been written)

Once in the news function you write your code (for example "view_news","add_news","edit_news") etcetera..

those will each get their link or redirect to their function, easily done by once you want it to get kicked in, you write:

CODE

view_news();

and it will open/include the view_news function, when you do it that way, your url will change:

CODE

index.php?act=view_news

in view_news you can do the same, but, if you have permissions set (guests cant see news for example) you dont have to do it with opening the function within[b] a function, you just redirect it with the necessary (or unnecessary) tools:
CODE
index.php?act=view_news&permission=".$permission."

wich, if its a guest who cant view, will change the url once in the page (and with necessary text to show the visitor it may not see it):
CODE
index.php?act=view_news&permission=false

in the example i used, the permission is checked (wich will be used in the next function) together with the user or admin id (wich will also be needed in the next function), wich gives, for example if its user number 1100:
CODE
index.php?act=news&permission=true&id=1100

in your next function you can write down the code for a false permission and a true permission.

Now, that's not all,
at the end of your page, you need to add the following to get for example the [b]act=news:

CODE

//first we get the act, wich you can make anything you want!
switch($_REQUEST[act]){
//next we need to set a default, wich could be the "front_page" function
default:
front_page();
break;
//in our example we only make 1 switch..to the news...wich has multiple switches...
//so there are actually several switches, but not all have to be made here, since
//they are within the function, these codes are purely for the thing AFTER act=
//for example...act=news ... the rest behind it is WITHIN the function
case:
news();
break;
}

I hope this made a little sense..
its alot of code and dont want to go through it again >.>

just hoping it helps a bit, we all start from the beginning, im a tiny bit further wich gives me the privilige to be able to help others..right?

Hi..do I have to make the ID variable into a SESSIon or a COOKIE variable in this case? thanks.

palladin

Aug 22 2005, 07:26 AM

For cookies:

setcookie(cookieid as string, cookie value, expiration date);
example:

CODE

<?php
setcookie("USER", "GUEST", time()+3600)
?>

expiration date are counting in seconds so call php time() function give you actual time + 3600 seconds (1 hour) after this time cookie was deleted.

setcookie mmust be called before html HEAD section was end;

for get cookie just call

CODE

<?php
$user = $_COOKIE("USER");
?>

evrywhere you wanna

Session was little more complex: here a link for php help :]

Panda

Most of the time, when you see something like that, it means that the page is part of a dynamic site. It's usually run off of some CMS (Mambo, Joomla, or someother one). For example:

CODE

http://roslyn.busstop.trap17.com/mambo/index.php?option=com_content&task=view&id=15&Itemid=26

is what Mambo produces, and this:

CODE

http://busstop.trap17.com/blog/index.php?p=28

is what WordPress puts out. Hope this clarifies things for you.
