Thumbs up How would you do this?
how would you create a link in php from one page to another, im guessing the

header ('Location http://www.etc.com');

as im building an index file - i want when the user clicks on a button hyperlink they will be redirected to that other page from within the index.php file

Any thoughts?

thanks everybody

User interaction is done client side, PHP is run server side. You would have to do this with AJAX which if I understand what you want correctly, would probably be overkill. You can use Javascript and CSS to hide or show content that is written into the HTML document to start with. PHP can write that document, but it's up to Javascript/CSS from there to do anything in response to what the user does.

If you mean something like index.php?page=one shows one page and index.php?page=two shows another, then it's simple.

$_GET["page"] is the "one" or "two" from above. Just check whether it matches a certain string, and include() the right file if it does.
PHP Code:
<?php

if (!isset($_GET["page"])) $_GET["page"]="index"; // default

// the {}s are *required* for the code below, even
// though it's only one statement in each IF
if ($_GET["page"]=="one") {
    include "asdf.php";
} else if ($_GET["page"]=="two") {
    include "qwerty.php";
} else { // default
    include "index.php";
}

?>

You're referring to what is commonly known as the front controller pattern. The example requinix provided illustrates this nicely; you can take this one step further and create some rewrite rules in a .htaccess file (if your host serves PHP via Apache) that direct the user to this script via separate URLs, e.g.
Code:
RewriteEngine On
RewriteRule ^one\/?$ index.php?page=one [L]
RewriteRule ^two\/?$ index.php?page=two [L]


So the users access these via
yourdomain.com/ (default action)
yourdomain.com/one (index.php?page=one)
etc

As a fallback, if the user tries to access anything else, they will be shown the default page, e.g.
yourdomain.com/foo (still shows the default index)

What's this line supposed to do?
PHP Code:
if(!isset($_GET["page"]))$_GET["page"]"indexadp"; 

is it supposed to be
PHP Code:
if(!isset($_GET["page"]))$_GET["page"]="indexadp";

First, don't use backslashes (\) for the include()d files. Use forward slashes (/) instead.

Second: Are you posting all the code? What line number is the error occurring on?
