- 1. #CMSX #ChunkyWP@jeckman Beyond Posts & Pages: Structured Content in WordPress John Eckman ISITE Design | CMS Myth
- 6. #CMSX #ChunkyWP@jeckman Shirts First five people to tweet: “Learning how to make WordPress Chunky with @jeckman at #cmsx #chunkyWP” 6
- 7. #CMSX #ChunkyWP@jeckman Agenda • Why do we need structured content? • How does WordPress do it? – Metadata – Custom Post Types – Custom Taxonomies • Examples – Basic: Slides, Alerts – Complex: Stories • Notes – Search – Controlling display – Relationships 7
- 9. #CMSX #ChunkyWP@jeckman Adaptive Content Five Key Elements of Adaptive Content: 1.Reusable content – Content developed to maximize reuse – Different formats/types available 1.Structured content – Discrete chunks can be combined in different ways on different platforms 9 http://www.abookapart.com/products/content-strategy-for-mobile
- 10. #CMSX #ChunkyWP@jeckman Adaptive Content, Cont’d 3. Presentation-independent content – Design decisions made by platform based on rules, not by authors 3. Meaningful metadata – Metadata which can be used by the platform to drive presentation rules 3. Usable CMS interfaces – UI and workflow to encourage well structured and metadata-enhanced content 10
- 13. #CMSX #ChunkyWP@jeckman WordPress Chunks To enhance structured content in WordPress, we need more: •Custom Post Types – Not just “pages” and “posts” – Complex content types •Custom Taxonomies – Sort, categorize, relate •Custom Meta Data – More boxes for granular data 13
- 16. #CMSX #ChunkyWP@jeckman Code Example (Simple) 16 http://codex.wordpress.org/Function_Reference/register_post_type
- 17. #CMSX #ChunkyWP@jeckman Code 17 Key is register_post_type Arguments passed control: •What to call it (Labels) •Where to show it – Public, Show UI, Searchable, has_archive – Menu position •Who can use it (capabilities) •What it includes (supports) http://codex.wordpress.org/Function_Reference/r egister_post_type
- 19. #CMSX #ChunkyWP@jeckman Example: Meteor Slides 19
- 22. #CMSX #ChunkyWP@jeckman More Complex Example • Client: Generation Citizen • Custom Post Type for “Stories” • Secondary HTML Areas • Custom Taxonomies: Locations, Topics • Custom Metadata • Attachments 22
- 23. #CMSX #ChunkyWP@jeckman Demo – Stories page 23
- 24. #CMSX #ChunkyWP@jeckman Secondary HTML Areas 24 http://wordpress.org/exten d/plugins/secondary-html- content/
- 25. #CMSX #ChunkyWP@jeckman Secondary HTML areas 25
- 26. #CMSX #ChunkyWP@jeckman Taxonomies Custom Post Types can be further enhanced with custom Taxonomies In this case that means: •Register Taxonomy •Show custom meta box •Save on submit 26
- 27. #CMSX #ChunkyWP@jeckman 27 Here we have a custom post type for “Stories” with two custom taxonomies: Locations and Topics Here we have a custom post type for “Stories” with two custom taxonomies: Locations and Topics
- 28. #CMSX #ChunkyWP@jeckman 28 These Meta Boxes enable selection of Location / Topic from a pre-defined set These Meta Boxes enable selection of Location / Topic from a pre-defined set
- 29. #CMSX #ChunkyWP@jeckman Custom Taxonomy Code 29 http://codex.wordpress.org/Function_Reference/register_taxonomy
- 30. #CMSX #ChunkyWP@jeckman Show Custom Meta Box 30
- 31. #CMSX #ChunkyWP@jeckman Style Locations Box 31
- 32. #CMSX #ChunkyWP@jeckman Save on Submit 32
- 33. #CMSX #ChunkyWP@jeckman 33 We’ve also got custom meta data here for: •Pull Quote •School •Teacher •Democracy Coaches
- 34. #CMSX #ChunkyWP@jeckman Custom Meta Boxes • Process for these other meta boxes is similar: – add_meta_box() passed a styling function – style function outputs the html needed – save function added to save_post action – update_post_meta to store 34
- 36. #CMSX #ChunkyWP@jeckman Notes • Search – WordPress search does not search custom post meta data – This means secondary html areas – http://wordpress.org/extend/plugins/relevan or other search • Display – You’ve customized the content so you can’t rely on <?php the_content() ?> 36
- 38. #CMSX #ChunkyWP@jeckman Q & A • Model content first • Find the tradeoff – More structure = more complexity – Less structure = less flexibility • Focus on goals – why before how • Go forth and structure content! 38

- Why do we need structured content? If we ever hope to get to adaptive content we need structure.
- Arguably, by default, WordPress creates “blobs” – what does in to that big primary WYSIWYG editor is a mixture of headings, subheadings, callouts, images, and other content – but in a fully unstructured way.
- But we do actually have some existing metadata: Date Categories Tags Title Excerpt Post Thumbnail / Featured Image Author info (based on the logged in user). Further, media “attached” to the post are tracked as a relationship in meta and can be pulled up, including post-thumbnail.
- In this simple example, we get a custom post type for alerts but there isn’t really much complexity to it – otherwise it is mostly a blob. I do get to use the “date published” differently in the template
- Meteor slides plugin uses Custom Post Types to enable management of slideshows
- This is the code in the template itself – secondary html areas are mapped based on their names
- Example showing custom taxonomies. Here we’ve created a custom post type of “Stories” – and added two custom taxonomies, one for Location and one for Topics.
- Note: adding ‘ popular_items ’ => NULL, to the $labels array will suppress the “ tag cloud ” on the admin edit screen for the custom taxonomy
- Note we’re checking here to see if the nonce is correctly set (prevent forged form submission)
- Lengthy discussion about the future of WP – whether relationships between posts belongs in core or not. For now, there is the Posts2Posts plugin
