I have coded the script below from what I understand of a PHP 3 reference but I am using php 4.2.2 this does not work and I cannot find why from the PHP 4 manual online please help

<html>
<head>
<title>Untitled Document</title>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<?php
// links to the different info to display
echo"<a href=\"?page=about\">about</a> <a href=\"?page=web\">Web</a> <a href=\"?page=email\">email</a>";

if( $page == "about" )
{
echo "about";
}
if( $page == "web" )
{
echo "web";
}
if( $page == "email" )
{
echo "email";
}
?>
 
below the text data
</body>
</html>

Thanx but it still won't display the text. I want it to display different text for about, web and e-mail and it is just not showing up 😕

// links to the different info to display 

echo"<a href=\"?page=about\">about</a> <a href=\"?page=web\">Web</a> <a href=\"?page=email\">email</a>";

The URL of the page being .... "something.php"?

PS: if($_POST['page']=='about')
etc.

That doesn't work either I need filename.php?page=games to show games content and filename.php?page=web to show different content again but the content is just not showing. It works in PERL and ASP but I want to use PHP as well. :rolleyes:
thanx for your input though

This is happening 'coz register_globals is off in 4.2.2

For it to work: use

if(!empty($GET)) { extract($GET); }
else { extract($HTTP_GET_VARS); }

at the top of each page. This is make your script work with all versions of PHP.

Well, if you want to use filename.php, you have to say so in the URL...

Not if its the same filename.

if index.php is open, then to link to index.php?page=1

?page=1 is sufficient

http://www.php.net/manual/en/language.variables.predefined.php

from this document u can see that register_globals is off for php verision 4.2.0 and above

meaning that you cannot access ur $page directly.

u have to use things like
if ($HTTP_GET_VARS['page']=="web")
{
blah blah blah
}

$HTTP_POST_VARS['page'] is only when they are sent thru the http headers using forms or headers command.

hope this helps

cheers guys I finally got the code to work and for those of you that are interested it looks like this

<html>
<head>
<title>Untitled Document</title>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<?php
// links to the different info to display
echo"<a href=\"?page=about\">about</a> <a href=\"?page=web\">Web</a> <a href=\"?page=email\">email</a>";

if(!empty($GET)) { extract($GET); }
else { extract($HTTP_GET_VARS); }

if ($HTTP_GET_VARS['page']=="about")
{
echo "blah blah blah";
}
if ($HTTP_GET_VARS['page']=="web")
{
echo "blah blah blah";
}
if ($HTTP_GET_VARS['page']=="email")
{
echo "blah blah blah";
}
?>
below the text data
</body>
</html>

Thanx again for your help

Mod of the code so it works with external files (what I originally intended the dynamic content for)

if ($HTTP_GET_VARS['page']=="about")
{
include ("about.txt");
}
if ($HTTP_GET_VARS['page']=="web")
{
include ("web.txt");
}
if ($HTTP_GET_VARS['page']=="email")
{
include ("email.txt");
}
?>
below the text data
</body>
</html>
