Hi All,

I am currently designing a site and was wondering if anyone knew of a script that allowed the URL showed in the address box to be showed as something like;

http://mysite.com/index.php?=home

And changing "home" to something else to link to another page.

Any help or ideas would be greatly appreciated.

Many thanks,

ZeNLoK

You could do that with some basic php. It's easier if you'd want http://mysite.com/index.php?page=home or something like that (notice the 'page=' instead of '=').

If it was the link I posted you could have a code like this:

PHP: 
<?php
if($_GET["page"] == "home") {
include "home.php";
exit;
}
?>
<html>
<!-- real index.php -->
</html>
This script would import from "home.php" when page=home is specified.

if you don't want the "page=" part to show up: http://mysite.com/index.php?home

There is a slightly different procedure.

PHP: 
<?php
if (isset($_GET['home'])) {
    //load page named "home"
} elseif (isset($_GET['something'])) {
   //load page named "something"
} else {
   //here load a default page, for instance an error message or something like that to tell users that the page they choose does not exist.
}
?>

For a fully general solution,

1. Put your files in a subdirectory like site_pages, so it will be harder for users to go directly to the page.

2. I assume they will all have .php extensions

3a. URL of "index.php?show=portfolio" (substitute 'page', 'request' , 'q' etc for 'show' )
PHP: 
$directory = 'site_pages/' ;
$default_page = 'site_pages/default.php' ;

if( isset( $_GET[ 'show'] ){

  $stub = $_GET[ 'show'];
 
  if( preg_match(  '/(\.|\/|\\)/' , $stub ) ){   ## make sure no .  or /  or \  to foil hackers 
      $requested_page = $default_page ;
  } else {
      $requested_page = $directory . $stub . ".php" ;
      if( ! is_file( $requested_page ) ){  ## no file, serve up default
         $requested_page =  $default_page ;      
     } 

} else {

  $requested_page =  $default_page ;

}

include( $requested_page ) ;

exit() ;

3b URL of "index.php?portfolio" (substitute the page name for 'porfolio' ). Add a elseif (...) { ... } block for each page you make.
PHP: 
<?php
$directory = 'site_pages/' ;
$default_page = $directory .  'default.php' ;

if ( isset( $_GET[ 'index'] )){
  $stub = 'index';
} elseif ( isset( $_GET[ 'page2'] )){
  $stub = 'page2';
} elseif ( isset( $_GET[ 'page3'] )){
  $stub = 'page3';
} else {
  $stub =  'default';
}

$requested_page = $directory . $stub . ".php" ;
if( ! is_file( $requested_page ) ){
   // no file, serve up default
   $requested_page =  $default_page ;      
} 

include( $requested_page ) ;

exit();
?>

descalzo, you could improve your code by doing a switch... it would be more efficient.
Oh and you forgot a ) after the if statement.

Click to expand...

But then if he adds 15 new pages, he has to add 15 new cases to the switch, with the possibility of misspelling a case, etc.

I'd stay away of any "general" possibilities, if you mess up the slightest bit a hacker can find an easy way in. Maintaining a list of pages is far better.

Why do you want to be able to do this? If you are just curious as to how it's possible I think the answer has been given many times.
There are a number of downsides to this too. You'd have to update that page if you want to add a new page. (Did I hear the word typo?) I think it'd be more efficient to just add a file. Also, some search engines don't like urls like that and will just skip them, assuming it's dynamical generated content, not a static page (usually they're only interested in static pages).
Most of the time you hear questions like this:
I have this news page with urls like this: news.php?id=15 but I've seen many sites that use urls like news/15/ instead. How is it possible to do this?

So it's up to you, but in general there would be no need to do this.
