PHP newbie alert

Often, I see websites that link to the other pages by linking to the same PHP file, but adding different queries. Example: This forum. Every thread is requested from the same showthread.php, but with a different query like ?tid=45715.

How do I do this?

Hope that makes sense. If not, please ask me to clarify.

well this forum uses the tid get value to know what thread to grab from the database , but i think you want to use something really simple like

code:

---

<?php
$x = isset($_GET['page']) ? $_GET['page'] : 'home';
if($x=='about'){?>
<--- about page html here --->

<? }else if($x=='other'){ ?>

<--- other page html here --->

<?}else{?>

<--- defult page html here --->
<? }?>

---

so say if someone goes to your page blah.php?page=about it will show <--- about page html here --->
thats for a really simple one though...

Yes, that's what I wanted, not using my database. Thank you. Have a cookie . Hmmm ... that cookie doesn't look that great, have a drumstick as well . I think that I'll use it with  $_REQUEST instaed of $_GET.

Is there a bit of myCode equivalant to <pre>?
[/pff topic]

If the file gets really big, will it slow down the site?

Guido, we need yummy-looking cookies .

Update: Yay, now I forgot         where I wanted to use this .
Update: Yay, now I remember     where I wanted to use this . Where are my Post-its?

If the file gets really big, it might slow the server slightly.

And the closest to a BBcode equivalent of <pre> is [code].

I would do something like this...

code:

---

<header>
<?php
if (!$a) { $a = "home"; }

include $a.".txt";
?>
<footer>

---

then have a file for each page, so index.php?a=links would load links.txt in the middle of the page. This way is better i think because you can add new pages without changing the main file.

It's dangerous to do that. What if I browse to page.php?a=../some_passwd_file
The visitor will be able to access a lot of private files on the server when you use the way saralk suggested, you should build in a protection at least.

you should put those files in another folder, then they could only do that if they use ../

[code]
<header>
<?php
if (!$a) { $a = "home"; }

include somefolder.$a.".txt";
?>
<footer>

/www/specialfolder/../../ will still point to /

I use it on my website too, I have it like this

I hope it's secure else tell me how to make it better

code:

---

function pagina ($page){
   $pad = "paginas/".$page.".php";
   if(!file_exists($pad))
   {
      include("paginas/notfound.php");
   }
   else
   {
      include($pad);
   }
}
if(!isset($_GET["pagina"]) OR $_GET["pagina"] == "")
{
   pagina("home");
}
else
{
   pagina($_GET["pagina"]);
}

---

Edit: Automatic coloring would be nice

ive always done it like this:

code:

---

<?php
$page = htmlentities($_GET['page']) ;
if (!isset($_GET['page'])) {
include ("home.php");
}
else {
$filename = "pages/$page.php";
if (file_exists($filename)) {   
include("pages/$page.php"); }
else {   
echo "Sorry, The Page Cannot Be Found";}
}
?>
