I have a header.tpl file that defines all the opening code for my pages, including the entire <head> section. In that template is a include_php statement to include a php file which in turn uses global PHP variables. The problem is that the included PHP file in the tpl file seems not to have access to the global PHP scope because no values are substituted.

I can't convert these PHP variables to template vars because the PHP file in question is actually a dynamically generated CSS file. In this file (style.php) all my CSS rules are dynamically selected according to the value of a cookie.

Is there something I'm missing on how to make php includes work with global PHP variables?

Or, do I have to completely change my dynamic CSS system to fit with Smarty? Most projects I've seen seem to use static CSS files that get selected by a switch, rather than using a dynamic CSS file. I obviously like the latter approach.

Eg.

{* Smarty template *}
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<head>

<title>{$page.title}</title>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"></meta>
<meta http-equiv="Content-Language" content="EN"></meta>
{$page.metaTags.description}
{$page.metaTags.keywords}
<meta name="robot" content="index,follow"></meta>
<meta name="copyright" content="Copyright © 2003 Knowledge Institute. All Rights Reserved."></meta>

<meta name="generator" content="Quanta Plus - free editor for Linux"></meta>
<meta name="Revisit-After" content="30 days"></meta>
<meta name="MSSmartTagsPreventParsing" content="TRUE"></meta>

{include_php file="/web/dev.buzgate.org/public_html/styles/defaultStyle.php"}
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon"></link>

**********************************************************************************************

Excerpt from CSS file:

BODY, TABLE, TD {
font-family:verdana,arial,helvetica;
font-size:12px;
color:<?php echo $_bm['colors']['black']; ?>;
background-color:transparent;
margin:0px;
padding:0px;
/*for easy debugging, turn on*/
border:0px solid green;
scrollbar-face-color: <?php echo $_bm['colors']['midnight']; ?>;
scrollbar-highlight-color: <?php echo $_bm['colors']['morning']; ?>;
scrollbar-3dlight-color: <?php echo $_bm['colors']['morning']; ?>;
scrollbar-darkshadow-color: #000000;
scrollbar-shadow-color: <?php echo $_bm['colors']['dusk']; ?>;
scrollbar-arrow-color: <?php echo $_bm['colors']['night']; ?>;
scrollbar-track-color: <?php echo $_bm['colors']['dusk']; ?>;
}

Thanks,

Greg

I needed to explicitly make the variables used within the included page global by putting this at the top of the file:

<?php global $_bm; ?>

Idea Idea So, apparently any included php file (inside a template) will lose all access to global variables, and so you need to pull them into the local scope with the 'global' command. This should be documented in the manual. Idea Idea
