This site runs PHPNuke
with phpBB forums.
I decided to work on my theme.
While trying to work on the forum theme I found that CSS changes don't work..
Investigating further, I found that the stylesheet for the forums was written in the html in the <BODY> after the default menu bars. The browser just ignores it.
I visited MANY other PHPNuke sites and found the same problem there as well.
Apparently it's the contents of overall_header.tpl that are being placed in the <BODY>.
PHPNuke builds the <HEAD> section, followed by the top menu bar (in theme.php) then calls phpBB.
The forum thinks it's running on a site by itself, so the overall_header.tpl file writes the page including it's own <HEAD> tags. Since PHPNuke has already written the tags and closed them, everything between the new <HEAD> tags is ignored by the browser. They just show up as garbage when you do a View-->Source.
In header.php the stylesheet is called by:
| Code: |
echo "<LINK REL="StyleSheet" HREF="themes/$ThemeSel/style/style.css" TYPE="text/css">"; |
In theme.php for any theme, I can put the following in Function themeheader:
| Code: |
/************************************************************/
/* Function themeheader() */
/* $name added to global */
/************************************************************/
function themeheader() {
global $banners, $sitename, $name;
/************************************************************/
/* replace blocks(left); with */
/************************************************************/
if ($name=='Forums') {
/* Don't display left blocks, any other code if forums active goes here */
}
else {
blocks(left);
} |
This makes the forum go full screen except for the site header/navbar. The forums here work in this manner.
The if ($name=='Forums') test works in header.php, so I can use it to write forum head tags when forums are active.
I just remove all code above and including the </HEAD> tag in overall_header.tpl then modify header.php/function head to contain that code, like this:
| Code: |
function head() {
global $name, $slogan, $sitename, $banners, $nukeurl, $Version_Num, $artpage, $topic, $hlpfile, $user, $hr, $theme,
$cookie, $bgcolor1, $bgcolor2, $bgcolor3, $bgcolor4, $textcolor1, $textcolor2, $forumpage, $adminpage, $userpage, $pagetitle;
include("includes/ipban.php");
$ThemeSel = get_theme();
include("themes/$ThemeSel/theme.php");
echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">\n";
echo "<html>\n";
echo "<head>\n";
echo "<title>$sitename $pagetitle</title>\n";
include("includes/meta.php");
include("includes/javascript.php");
if (file_exists("themes/$ThemeSel/images/favicon.ico")) {
echo "<link REL=\"shortcut icon\" HREF=\"themes/$ThemeSel/images/favicon.ico\" TYPE=\"image/x-icon\">\n";
}
echo "<link rel=\"alternate\" type=\"application/rss+xml\" title=\"RSS\" href=\"backend.php\">\n";
if ($name=='PHP-Nuke_HOWTO') {
echo "<LINK REL=\"StyleSheet\" HREF=\"modules/PHP-Nuke_HOWTO/ck-style.css\" TYPE=\"text/css\">\n\n";
}
echo "<LINK REL=\"StyleSheet\" HREF=\"themes/$ThemeSel/style/style.css\" TYPE=\"text/css\">\n\n";
if ($name=='Forums') {
echo "<LINK REL=\"StyleSheet\" HREF=\"themes/$ThemeSel/forums/forums.css\" TYPE=\"text/css\">\n";
echo "<link rel=\"top\" href=\"modules.php?name=Forums&file=modules&name=Forums&file=modules/Forums/index\" title=\"AnOldMan.com Forum Index\" />\n";
echo "<link rel=\"search\" href=\"modules.php?name=Forums&file=modules&name=Forums&file=modules/Forums/search\" title=\"Search\" />\n";
echo "<link rel=\"help\" href=\"modules.php?name=Forums&file=modules&name=Forums&file=modules/Forums/faq\" title=\"Forum FAQ\" />\n";
echo "<link rel=\"author\" href=\"modules.php?name=Forums&file=modules/Forums/modules&name=Members_List&file=index\" title=\"Memberlist\" />\n";
}
if (file_exists("includes/custom_files/custom_head.php")) {
include_once("includes/custom_files/custom_head.php");
}
echo "\n\n\n</head>\n\n";
if (file_exists("includes/custom_files/custom_header.php")) {
include_once("includes/custom_files/custom_header.php");
}
themeheader();

Stylesheets are parsed by browsers based on the last declaration. I am setting two stylesheets when forums are active, but only styles that are re-declared are affected. Of course, a lot of the site's style changes when forums are active, but since I have blocks(left); disabled then, the only part of the page truly affected is the menu bar. I have it's layout/style hardcoded in theme.php, so it makes no difference.
The result: no more code showing in the body when you view a page's source, and more importantly: the forum stylesheet now works!
I was amazed at the style changes evident after this, I had never seen phpBB in it's native color scheme before!

Remember: Questions
can be posted in the FORUM section !
whew! getting this page to parse properly with html and php
code in it was a nightmare!
