CTools Style Plugins: Demo & Code Walk-Thru
- 1. CTools Style Plugin Demo & Code Walk-Through Amber Himes IRC/d.o: agentolivia | Twitter: @amberhimes
- 2. What is CTools? • CTools = Chaos Tool Suite • A contrib project on drupal.org • Developer APIs and Tools • Page Manager • drupal.org/project/ctools
- 3. What is a CTools plugin? • A plugin is way for a module to allow another module or theme to implement a piece of functionality • Useful when you want to add or alter existing features of a module. • Types of plugins include contexts, content types, layouts, and style
- 4. Style Plugins • With a Style Plugin, define: • a settings form • how to render settings in a template
- 5. Where do I use it? • In the Panels interface, click on gear of pane and select “Style” • In Panelizer or Panopoly, click the Paintbrush icon Panopoly Example
- 6. Demo • Weber County Library in Ogden, UT • Panopoly distro, Panels IPE (In-Place Editor) • Live Preview of panel pane styles
- 7. Overview of steps • Create a custom module • Tell CTools about our plugin files • Define our $plugin array • Define our theme and form hooks • Create our template file and make use of returned values
- 10. weber_styles.module Implements hook_ctools_plugin_directory 1 <?php 2 function weber_styles_ctools_plugin_directory( $module, $plugin) { 3 return 'plugins/' . $plugin; 4 }
- 11. $plugin gotchas • Define $plugin array inside our .inc but outside any function • CTools knows to look for $plugin because we told it to in: hook_ctools_plugin_directory()
- 12. $plugin array Follow along... https://gist.github.com/agentolivia/5745929 => http://tinyurl.com/ctools-style-gist <=
- 13. ‘render pane’ • corresponds to the theme function that renders the pane, without “theme_” • If the theme function is named theme_panesandblocks_render_pane then the value for ‘render pane’ is ‘panesandblocks_render_pane’
- 14. ‘render pane’
- 15. ‘region pane’ • corresponds to the theme function that renders the region, without “theme_” • If the theme function is named theme_panesandblocks_render_region then the value for ‘render region’ is ‘panesandblocks_render_region’
- 16. ‘pane settings form’ • The full name of the function that returns the settings form. For example: panesandblocks_settings_form • The corresponding function: function panesandblocks_settings_form ($style_settings) • Use Form API to build form components. Set default values using $style_settings
- 17. ‘hook theme’ • Defines theme functions and variables for pane and region • Pane and Region will each have their own arrays of hook theme information • Array key = the first parameter of theme() returned in the corresponding theme_ function
- 18. hook theme key
- 20. render pane theme fxn 1 function theme_panesandblocks_render_pane($vars) { 2 $settings = $vars['settings']; 3 $content = $vars['content']; 4 5 return theme('panesandblocks_theme_pane', array('content' => $content, 6 'settings' => $settings)); 7 }
- 21. vars in template files • Whatever variables I listed in $plugin’s ‘hook theme’ are passed into the theme function which make these values available in my template files • $content and $settings seem to be the two preferred choices for variables in hook theme
- 22. vars gotchas • $settings is an array • $content is an object
- 23. tpl vars gotchas • $settings is an array • i.e. $settings[‘heading_classes’] • $content is an object • i.e. $content->title
- 24. use of vars in tpl 1 <?php if (isset($content->title)): ?> 2 <h3 class="<?php print (isset($settings['heading_classes'])) ? $settings['heading_classes'] : ''; ?>"> <?php print $content->title; ?></h3> 3 <?php endif; ?>
- 26. Print values from settings form in tpl.php • Use php print statements to output settings form values as CSS classes in your pane template file
- 28. Apply CSS • No need to bury a CSS file in a plugin directory • Do inspect the elements to make sure classes have been applied as expected
- 29. Inspect!
- 30. Troubleshooting tips • Add a css file through drupal_add_css at the top of your template file to get the preview working right away • Check all instances of panel panes to make sure they are rendering correctly, as this template file will override the panels- pane.tpl.php. • Add logic to theme function as needed
