Checking User Theme in custom PHP page
« on: April 20, 2010, 02:20:20 PM »
I have a little problem, I'm using a custom PHP page to include another file in my website. There are two stylesheets associated with this file, and I would like to use one or the other depending on the users theme. The style sheet is obviously just for the file that I am calling with the "include" code. However, I can't for the life of me get this to work on a custom page. The code im using at the moment is;
Code: [Select]
<?php
if ($user_info['theme'] == 9)
echo "<link href=\"abc/blue.css\" rel=\"stylesheet\" type=\"text/css\" />";
else echo "<link href=\"abc/grey.css\" rel=\"stylesheet\" type=\"text/css\" />";
include 'abc/scrape.php';
?>
However this doesn't work as it doesn't seem to be getting anything from the $user_info variable. I have tried using the code in a page not part of SimplePortal/SMF by using the "require_once('forum/SSI.php');" and that worked fine, changing style sheets whenever I switched between two themes, the require thing doesn't work in SimplePortal though. What I'm asking is, is it actually possible to do this in a custom php page in SimplePortal? If so, where exactly am I going wrong? Sorry if this is in the wrong forum, I figured this would be the best place to put it.

Thanks in advance,

Code: [Select]
global $user_info;
But you have another problem -- <link> should go in the html head. But, once the custom php code starts evaluating, you are already within <body>.  At this point, the only way to get to the head is with some javascript.  So you'll have to get your custom php to write some custom javascript for you.
 
Something like this -- did I make any errors in that first line?
Code: [Select]
$stylefile=  $settings['default_theme_url'] . (($user_info['theme']==9) ? 'abc/blue.css' : 'abc/grey.css' );
echo '
  <script language="JavaScript" type="text/javascript"><!-- // --><![CDATA[
   var cssNode = document.createElement("link");
   cssNode.type = "text/css";
   cssNode.rel = "stylesheet";
   cssNode.href = "', $stylefile, '";
   cssNode.media = "screen";
   cssNode.title = "dynamicLoadedSheet";
   document.getElementsByTagName("head")[0].appendChild(cssNode);
  // ]]></script>';

The above worked perfectly, thank you. The stylesheets seem to be working without the javascript, so I'm going to leave that alone for the time been. Thanks again! Been trying to figure this out for way too long.

The results of putting <link> in the body may be browser-dependent.
 
The HTML validator says document type does not allow element "link" here
