  1. 1. Grok Drupal Theming Laura Scott PINGV @lauras #grokd4d Drupal Design Camp LA 2011
  2. 2. Laura Scott Creative Director, Drupal Architect and Co-Founder PINGV Creative "laura s" drupal.org/user/18973 Drupal since 2004 @lauras
  3. 3. Grok Drupal Theming Grok means to understand so thoroughly that the observer becomes a part of the observed — to merge, blend, intermarry, lose identity in group experience. Robert A. Heinlein, Stranger in a Strange Land
  4. 4. <h1 id="title"> Grok Drupal Theming </h1>
  5. 5. <h1 id="title"> Grok Drupal Theming </h1> How Drupal displays content (templates) How to start theming Other things to consider
  6. 6. Assumptions • You know HTML/xhtml • You don't know PHP (but if you do, we won't • You know CSS 2.1 hold it against you) • You are at least getting • You understand some to know CSS 3 (or want basic Drupal to) architecture concepts • Drupal theming confuses • You want to learn this or mystifies you
  7. 7. Some PHP required • Mainly to print pre-defined variables … e.g., $title (for the page title). • You can do a lot in the "preprocess" and "process" functions. • You can avoid it if it totally scares the living daylights out of you. Just stick to copy and paste from '<?php' to '?>'.
  8. 8. HTML5 is coming! http://groups.drupal.org/html5
  9. 9. Theming for Drupal 7 is more powerful than previous versions ...but it's also a bit more complicated.
  10. 10. Anatomy of a Drupal "page" • xhtml, CSS, bg images • Content presented via templates • JavaScript
  11. 11. The Drupal theme • CSS files • Image files • Template files • JavaScript files • .info file • Preprocess and process new!
  12. 12. • CSS files • Image files • Template files • JavaScript files • Preprocess and process files • .info file
  13. 13. Which template? It depends....
  14. 14. Which template? page.tpl.php • logo • main title • regions • footer and • other templates
  15. 15. Which template? html.tpl.php new! page.tpl.php • !DOCTYPE • <head> stuff • Drupal calls for CSS and JavaScript* • <body> container
  16. 16. Which template? html.tpl.php page.tpl.php node.tpl.php • node title • node author • post date • node content • node taxonomy terms • node links
  17. 17. Which template? html.tpl.php page.tpl.php node.tpl.php comment-wrapper.tpl.php • Comment area title? • Comment templates
  18. 18. Which template? html.tpl.php page.tpl.php node.tpl.php comment-wrapper.tpl.php comment.tpl.php • Comment title? • Comment author • Comment content • Comment links
  19. 19. Which template? html.tpl.php page.tpl.php node.tpl.php block.tpl.php • Block title • Block content comment-wrapper.tpl.php comment.tpl.php *We'll come back to this, because there's one more very important thing.
  20. 20. Every module's output also has a template file. (In theory.)
  21. 21. 42 *.tpl.php files in D7's /modules folder. Each can be copied into your theme and used to override.
  22. 22. The Views UI gives you template code to override Views output.
  23. 23. One theme might have dozens of template files.
  24. 24. There are only a few basics. (It's not rocket science.)
  25. 25. What's inside a template?
  26. 26. html.tpl.php
  27. 27. html.tpl.php <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="<?php print $language->language; ?>" version="XHTML+RDFa 1.0" dir="<?php print $language->dir; ?>" <?php print $rdf_namespaces; ?>>

  55. 55. region.tpl.php <?php if ($content): ?> <div class="<?php print $classes; ?>"> <?php print $content; ?> </div> <?php endif; ?>
  56. 56. So if all regions use the same template, how does Drupal know which region?
  57. 57. <?php print render($page['header']); ?>
  58. 58. <?php print render($page['header']); ?> <?php print render($page['help']); ?> <?php print render($page['highlight']); ?> <?php print render($page['content']); ?> <?php print render($page['sidebar_first']); ?> <?php print render($page['sidebar_second']); ?> <?php print render($page['footer']); ?>
  59. 59. All regions in your theme must be declared, or else you get these defaults.
  60. 60. Where the heck are all these templates?
  61. 61. example.com/modules
  62. 62. Preprocess scary doesn't have to be
  63. 63. Everything is an array pretty much
  64. 64. So how to go about creating a theme?
  65. 65. Create a theme from scratch, making everything • theme .info file • page.tpl.php • *.tpl.php files as needed to override core • template.php for your preprocess and process • background images
  66. 66. or make a baby!
  67. 67. Sub-themes inherit everything from parent theme, except what is overridden.
  68. 68. Inheritance html.tpl.php page.tpl.php node.tpl.php block.tpl.php
  69. 69. Inheritance html.tpl.php page.tpl.php page.tpl.php node.tpl.php node.tpl.php block.tpl.php
  70. 70. Inheritance html.tpl.php html.tpl.php page.tpl.php page.tpl.php node.tpl.php node.tpl.php block.tpl.php
  71. 71. Inheritance base.css base.css type.css type.css forms.css
  72. 72. Many good base themes
  73. 73. Copy in the base theme example.com/themes/ example.com/sites/all/themes/basetheme
  74. 74. Create your child theme example.com/themes/ example.com/sites/all/themes/yourtheme
  75. 75. sites all themes yourtheme yourtheme.info template.php license.txt css images templates
  76. 76. yourtheme.info
  77. 77. yourtheme.info name = yourtheme description = This is where you describe your theme in words. version = 1.0 ; Requirements base theme = ninesixty core = 7.x engine = phptemplate ; Stylesheets stylesheets[all][] = styles.css stylesheets[screen][] = styles/base.css stylesheets[screen][] = styles/layout.css stylesheets[screen][] = styles/colors.css stylesheets[screen][] = styles/forms.css stylesheets[print][] = styles/print.css ; Regions regions[header] = Header regions[help] = Help regions[highlight] = Highlight regions[content] = Content regions[page_top] = Page top regions[page_bottom] = Page bottom regions[indicators] = Indicators regions_hidden[] = indicators ; Scripts scripts[] = script.js scripts[] = scripts/twitter.js
  78. 78. yourtheme.info name = yourtheme description = This is where you describe your theme in words. version = 1.0 ; Requirements base theme = ninesixty core = 7.x engine = phptemplate ; Stylesheets stylesheets[all][] = styles.css stylesheets[screen][] = styles/base.css stylesheets[screen][] = styles/layout.css stylesheets[screen][] = styles/colors.css stylesheets[screen][] = styles/forms.css stylesheets[print][] = styles/print.css ; Regions regions[header] = Header regions[help] = Help regions[highlight] = Highlight regions[content] = Content regions[page_top] = Page top regions[page_bottom] = Page bottom regions[indicators] = Indicators regions_hidden[] = indicators ; Scripts scripts[] = script.js scripts[] = scripts/twitter.js
  79. 79. In Drupal 7, if you're creating a theme from scratch, you must now declare style.css and script.js in your .info file, or they will not be included.
  80. 80. yourtheme.info name = yourtheme description = This is where you describe your theme in words. version = 1.0 ; Requirements base theme = ninesixty core = 7.x engine = phptemplate ; Stylesheets stylesheets[all][] = styles.css stylesheets[screen][] = styles/base.css stylesheets[screen][] = styles/layout.css stylesheets[screen][] = styles/colors.css stylesheets[screen][] = styles/forms.css stylesheets[print][] = styles/print.css ; Regions regions[header] = Header regions[help] = Help regions[highlight] = Highlight regions[content] = Content regions[page_top] = Page top regions[page_bottom] = Page bottom regions[indicators] = Indicators regions_hidden[] = indicators ; Scripts scripts[] = script.js scripts[] = scripts/twitter.js
  81. 81. Template Suggestions • Create a base template of that type • Create variations on it to apply in certain circumstances • No coding necessary http://drupal.org/node/190815
  82. 82. Template Suggestions by content type node.tpl.php blog node--blog.tpl.php event node--event.tpl.php classified node--classified.tpl.php product node--product.tpl.php
  83. 83. Template Suggestions by content type new! node.tpl.php blog node--blog.tpl.php event node--event.tpl.php classified node--classified.tpl.php product node--product.tpl.php
  84. 84. Delimiters use two: '--' Words still use one: '-' event-meeting node--event-meeting.tpl.php event-party node--event-party.tpl.php
  85. 85. new! And no longer need node.tpl.php in your theme in order to use node--event.tpl.php.
  86. 86. new! Wildcards in tpl names page--user--42.tpl.php page--user--%.tpl.php override all user displays without affecting /user
  87. 87. new! .clear-block is now .clearfix
  88. 88. Alter Hooks hook_page_alter() hook_form_alter() hook_css_alter() hook_js_alter()
  89. 89. Conditional CSS still needs trickery //IE6 overrides drupal_add_css( path_to_theme() . '/fix-ie.css', array( 'group' => CSS_THEME, 'browsers' => array( 'IE' => 'lt IE 7', '!IE' => FALSE ), 'preprocess' => FALSE ) );
  90. 90. new! Classes and Attributes are now standard and predefined without futzing (although you can still futz if you want).
  91. 91. <div id="example" class="<?php print $classes; ?> clearfix"<?php print $attributes; ?>> ... </div>
  92. 92. node.tpl.php <div id="node-<?php print $node->nid; ?>" class="<?php print $classes; ?> clearfix"<?php print $attributes; ?>> ... </div>
  93. 93. Attributes new! • $attributes • $title_attributes for titles • $content_attributes for content

  106. 106. Do I really need to do RDFa to use Drupal? No, you can just ignore it, and work on the same level as other systems. But you'll be missing out. Photo: FlySi flickr.com/photos/flysi/183272970/
  107. 107. Attributes • $attributes • $title_attributes for titles • $content_attributes for content
  108. 108. Basics to Remember • Create your theme in sites/all/themes/yourtheme • Copy templates into your theme to make overrides • Use template suggestions to break out distinct structures and stylings • Use base theme to get a jump on things • Let Drupal do what it does best
  109. 109. Points of Modification • CSS • xhtml in the template that applies • preprocess • module
  110. 110. Resources • Drupal 6 » Drupal 7 theming changes drupal.org/update/theme/6/7 • Template suggestions drupal.org/node/190815* • RDFa buytaert.net/semantic-web- and-drupal-video * Drupal 6
  111. 111. Get Drush! Yeah yeah yeah, I know, you don't like command line, but this will really really and for true help you save time developing so that you can spend more time designing and theming, and isn't that what you'd rather do anyway? Video to make it easy: http://is.gd/ aZe33
