Wikka Skin Selector


Theme support available in 1.2!

This page refers to beta functionality supported until Wikka 1.1.x. As of version 1.2 Wikka introduces support for 100%-modular themes: check this page for more information or this tutorial to learn how to design custom themes.
 

This action allows you to select a skin for WikkaWiki, among those present in the css/ folder.
Note: Your browser must accept cookies in order for the skin selector to work.

Here's the three-step installation:

1. Add your custom skins

Just put all your skins in the css/ folder of your Wikka installation.
Many skins can be downloaded and shared from the unofficial WikkaSkinsRepository.

2. Create the skin selector action (actions/selectskin.php)

Save the code below in a new file called actions/selectskin.php:
Minor update 2004-11-25

<?php
// Wikka Skin Selector
// Displays a form to switch CSS stylesheet

$currentskin = $this->GetCookie("wikiskin");
echo $this->Format("=== Select a Wikka skin:  === --- ");
if ($_POST) {
            $this->SetPersistentCookie("wikiskin", $_POST["skin"]);
            $this->Redirect($this->href());
}
$handle = opendir('css/');
print $this->FormOpen("","","post");
echo '<select name="skin">';
$noskinmask = '^(xml.css|print.css|\.(.*))$';
while (false !== ($file = readdir($handle))) {
    if (!preg_match('/'.$noskinmask.'/', $file)) {
        $selected = ($file == $currentskin)? " selected=\"selected\"" : "";
        print   '<option value="'.$file.'"'.$selected.'>'.$file.'</option>';
    }
}
echo '</select>';
echo '<input type="submit" name="Submit" value="Set new skin" />';
print $this->FormClose();
closedir($handle);
?>


3. Modify the Wikka Header (actions/header.php)

To allow skin selection a small modification of the header is needed:

original actions/header.php
  <link rel="stylesheet" type="text/css" href="css/<?php echo $this->GetConfigValue("stylesheet") ?>" />


modified actions/header.php
<link rel="stylesheet" type="text/css" href="css/<?php echo ($this->GetCookie("wikiskin"))? $this->GetCookie("wikiskin"): $this->GetConfigValue("stylesheet") ?>" />


How to use the skin selector


Just insert {{selectskin}} in a wikka page and start playing.
