I got this to work using this in my template.php file:
$banners = theme_get_setting('banners'); switch($banners) { case ("white-gray"): drupal_add_css(path_to_theme() . '/white-gray.css', 'theme', 'all'); break; case ("blue-gray"): drupal_add_css(path_to_theme() . '/blue-gray.css', 'theme', 'all'); break; default: drupal_add_css(path_to_theme() . '/red-blue.css', 'theme', 'all'); break; }
And this in my theme-settings.php file:
<?php function graphicDesign_settings(&$saved_settings) { $defaults = array( 'banners' => 'red-blue', ); $settings = array_merge($defaults, $saved_settings);
$form['banners'] = array( '#type' => 'select', '#options' => array( 'red-blue' => 'Red/Blue', 'blue-gray' => 'Blue/Gray', 'white-gray' => 'White/Dark Gray'), '#default_value' => $settings['banners'], '#title' => t('Choose a Banner Color Combination'), ); return $form; }
Quoting Brent Hardinge brent@hardinge.net:
Tracey,
It seems that in order to get the css into the system, you need to use drupal_add_css outside of the preprocess function because it is the template_preprocess_page function that is used to add the css to the $variables['styles'] function.
So what I would recommend doing is adding the following at near the top of your template.css file:
drupal_add_css(path_to_theme() . '/' .theme_get_setting('banners') .'.css', 'theme', 'all');
That should replace your switch function and print the appropriate css file based on the settings.
Cheers, Brent

My trying a add page preprocess that will allow site administrators to be able to configure a theme and choose different banners/color combinations. Based on what they select, a different css file would be added that would modify the banners graphics/colors.
I added three choices to the theme's configuration page by adding this to the theme-settings.php file:
function graphicDesign_settings(&$saved_settings) { $defaults = array( 'banners' => 'red-blue', ); $settings = array_merge($defaults, $saved_settings);
$form['banners'] = array( '#type' => 'select', '#options' => array( 'red-blue' => 'Red/Blue', 'blue-gray' => 'Blue/Gray', 'white-gray' => 'White/Dark Gray'), '#default_value' => $settings['banners'], '#title' => t('Choose a Banner Color Combination'), ); return $form; }
In the template.php file, I'm trying to use the variable passed to add a css file based on what they select. In the template.php file:
function graphicDesign_preprocess_page(&$vars) { $banners = theme_get_setting('banners'); drupal_set_message(print_r($banners,true));
switch($banners) { case ("white-gray"): drupal_add_css(path_to_theme() . '/white-gray.css', 'theme', 'all'); break; case ("blue-gray"): drupal_add_css(path_to_theme() . '/blue-gray.css', 'theme', 'all'); break; default: drupal_add_css(path_to_theme() . '/red-blue.css', 'theme', 'all'); break; } }
The css is not being added. Is anyone doing something similar and would be willing to help me?
Thanks, Tracey
