Css-Switcher

The CSS Switcher plugin is a simple way to allow skinning on a CSS formatted site.

The tag will look for an incoming $_GET (url), $_POST (forms), or $_COOKIE (cookies) variable, which the name of can be specified in the plugin file, to see if a CSS file has been requested. If it has, then it will be pulled from an array of CSS file locations in the plugin file and outputted as the {file} variable. Also, it will store the name of that CSS file in a cookie so it can be retrieved whenever the user visits the site again.

Here is a quick example using a form.

  1. You update the $css array in the CSS_Switch class in pi.css_switcher.php:

    var $css = array(
        '1' => "http://example.com/index.php?css=weblog/weblog_css",
        'apples' => "http://example.com/index.php?css=weblog/weblog2_css",
        'oranges' => "http://example.com/index.php?css=weblog/weblog3_css",
        '4' => "http://example.com/index.php?css=weblog/weblog4_css"
    );
    
  2. You put the following in the <head> tags of your pages:

    {exp:css_switcher}
        <link rel='stylesheet' type='text/css' media='all' href='{file}' />
        <style type='text/css' media='screen'>@import "{file}";</style>
    {/exp:css_switcher}
    
  3. You set up a form on your front page where the user chooses their skin and submits the form:

    <form action="index.php" method="post">
        <select name="css_skin" id="css_skin">
            <option value="1">Default</option>
            <option value="apples">Apples</option>
            <option value="oranges">Oranges</option>
            <option value="4">Pineapples</option>
        </select>
    </form>
    
  4. CSS Switcher finds the requested member of the $css array and puts in the requested CSS file's URL. Then, a cookie is set that will have that CSS file presented the next time the site is viewed.

Parameters

The tag also has two optional parameters.

  • setting="" - Used to change how the CSS files are chosen. Three different possible settings.
    • setting="normal": Relies on the $_GET, $_POST, or $_COOKIE variables to choose a member of the array. If neither of those are found or the one found is not in the array, then it chooses the default member of the array
    • setting="random": Will randomly choose any member of the $css array in the plugin file.
  • setting="day": Will choose a stylesheet depending on the day of the week. The keys of the array must either be a number or abbreviation for the day of the week. Possible array keys are: 1, Sun, 2, Mon, 3, Tue, 4, Wed, 5, Thu, 6, Fri, 7, Sat.
  • files="" - Creates the $css array on load using the stylesheet URLs listed in the parameter. Separate each URL with a pipe ("|"). The first stylesheet will be given an array key of 1, and the rest after will be incremented by a value of one (2, 3, 4, etc.) by their order.
