Constant Variable

[vicodin]

I am working on creating like a framework for my site and i want to create a constant variable like $pagename = "Index" and now when i include my functions and i call for the variable $pagename will it look at the constant variable $pagename? If it will not how do i get it to use the constant?

i'm afraid I don't understand your question..

 

are you trying to like say make an index.php page.. and then to navigate through your site pages make links like this?:

 

http://yoursite.com/index.php?p=index

are you talking about normal constants or class constants?

 

normal constants don't have $ signs on them. once declared, they are global and can be seen by any function/class. here is info on how to use them:

[ag3nt42]

it sounds like via the "$pagename" variable that he wants to use it for navigation

Ok i am making a function so that what ever page i'm on it wont make it a link in my navigation. So i want to declare in what ever page it is the $pagename and i want my functions to pick up on $pagename and use that.

 

[rhodesa]

preferably, pass it as an argument to the function. if this isn't an option, you can try using the global keyword:

hmm,

 

I use a similar thing for my pages.. where I have an index page then all my other site pages are included to that page... and I just use the "$_GET" to change includes..

 

index.php:

<?php

if(isset($_GET['p']))
{
if($_GET['p']=='home')
{
include('home.php');
}
}

?>

 

then the navigation links on my site look like this

 

http://mysite.com/?p=index

 

 

i think it works rather well myself

The words Constant and Variable contradict each other.

You can also just get the name of the current page with this:

 

<?php

$this_page = basename($_SERVER['REQUEST_URI']);

if (strpos($this_page, "?") !== false) $this_page = reset(explode("?", $this_page));

?>

 

Just clean up the string a bit more and you'll always know where you are.

This does work.

 

 

Function...

function linkto_unlesspage($name,$link,$extra = NULL){
$pagename = constant("page");
if (!($name == $pagename)){
echo '<a href="'.$link.'" '.$extra.'>'.$name.'</a>';
}else{
	echo $name;

 

 

page...

define("page","Home");
include('func.inc');
linkto_unlesspage("Home","index.php");
