Re: [Phpwebsite-developers] 0.9.4 Theme Change

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Yesterday I worked with Mike on the debug theme. He asked that a couple
things happen. First, the <meta http-equiv="content-type"
content="text/html; charset=ISO-8859-1" /> needs to go away if the
document is treated as an xml file. 

Secondly, he asked that stylesheets be added to the theme. The details
are here:
http://www.w3.org/TR/xml-stylesheet/
While the change is fairly simple on the surface, one problem arose. The
stylesheets are moved from the document into the headers. Since I can't
access the {STYLE} tag via theme.php I chose to eliminate it and add a
tag called {STYLESHEETS}. This would obviously be unnecessary if done
within Layout.  Here is the code I used:
theme.php
<?php
if(stristr($_SERVER["HTTP_ACCEPT"],"application/xhtml+xml")){ 
    @header("Content-Type: application/xhtml+xml; charset=UTF-8");
    $THEME["XML"] = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
    $THEME["XML_STYLE"] = set_style();
    $THEME["XML_ALT_STYLE"] = '';
    $THEME["DOCTYPE"] = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML
1.1//EN\"
      \"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd\">";
    $THEME["HTML"] = "<html xmlns=\"http://www.w3.org/1999/xhtml\"
xml:lang=\"en-US\">";

} else { 
    @header("Content-Type: text/html; charset=UTF-8");
    $THEME["DOCTYPE"] = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0
Strict//EN\"
      \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">";
    $THEME["HTML"] = "<html xmlns=\"http://www.w3.org/1999/xhtml\"
xml:lang=\"en\" lang=\"en\">";
    $THEME["STYLESHEET"] = "<link rel=\"stylesheet\" href=\""
      .$_SESSION["OBJ_layout"]->theme_address."style.css\"
type=\"text/css\"?>";
}

$_SESSION["OBJ_layout"]->meta_content = FALSE;

function set_style(){
    $alt_css = $_SESSION["OBJ_layout"]->theme_dir."browsers.txt";
    $css = '';
    if (file_exists($alt_css)){
      $altStyles = file($alt_css);
      fore<?php
if(stristr($_SERVER["HTTP_ACCEPT"],"application/xhtml+xml")){ 
    @header("Content-Type: application/xhtml+xml; charset=UTF-8");
    $THEME["XML"] = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
    $THEME["XML_STYLE"] = set_style();
    $THEME["XML_ALT_STYLE"] = '';
    $THEME["DOCTYPE"] = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML
1.1//EN\"
      \"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd\">";
    $THEME["HTML"] = "<html xmlns=\"http://www.w3.org/1999/xhtml\"

      \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">";
    $THEME["HTML"] = "<html xmlns=\"http://www.w3.org/1999/xhtml\"
xml:lang=\"en\" lang=\"en\">";
    $THEME["STYLESHEET"] = "<link rel=\"stylesheet\" href=\""
      .$_SESSION["OBJ_layout"]->theme_address."style.css\"
type=\"text/css\"?>";
}

$_SESSION["OBJ_layout"]->meta_content = FALSE;

function set_style(){
    $alt_css = $_SESSION["OBJ_layout"]->theme_dir."browsers.txt";
    $css = '';
    if (file_exists($alt_css)){
      $altStyles = file($alt_css);
      foreach ($altStyles as $style){
          $temp = explode("::", $style);
          if (preg_match("/".$temp[0]."/", $_SERVER["HTTP_USER_AGENT"])
&& file_exists($_SESSION["OBJ_layout"]->theme_dir.trim($temp[1]))){
              $css .= "<?xml-stylesheet alternate=\"yes\"
title=\"compact\" href=\"" . $_SESSION["OBJ_layout"]->theme_address .
trim($temp[1]) . "\" type=\"text/css\" ?>\n";
              $browser_css = 1;
              break;
          }
      }
    }

    if (!isset($browser_css) &&
file_exists($_SESSION["OBJ_layout"]->theme_dir."style.css"))
        $css = "<?xml-stylesheet
href=\"".$_SESSION["OBJ_layout"]->theme_address.
          "style.css\" type=\"text/css\"?>";
    return $css;
}
?>ach ($altStyles as $style){
          $temp = explode("::", $style);
          if (preg_match("/".$temp[0]."/", $_SERVER["HTTP_USER_AGENT"])
&& file_exists($_SESSION["OBJ_layout"]->theme_dir.trim($temp[1]))){
              $css .= "<?xml-stylesheet alternate=\"yes\"
title=\"compact\" href=\"" . $_SESSION["OBJ_layout"]->theme_address .
trim($temp[1]) . "\" type=\"text/css\" ?>\n";
              $browser_css = 1;
              break;
          }
      }
    }

    if (!isset($browser_css) &&
file_exists($_SESSION["OBJ_layout"]->theme_dir."style.css"))
        $css = "<?xml-stylesheet
href=\"".$_SESSION["OBJ_layout"]->theme_address.
          "style.css\" type=\"text/css\"?>";
    return $css;
}
?>

theme.tpl would then include:
{XML}
{XML_STYLE}
{XML_ALT_STYLE}
{DOCTYPE}
{HTML}
{STYLESHEET}

<!-- Replaced {STYLE} with {STYLESHEET} -->

HTH,
