How do Custom Fields work?

Key/value pairs

“Key” – “name” – a constant that identifies a specific field Stays the same for all posts, cannot be duplicated

Can be called multiple times on one page

Value – info displayed for each field when you call it Can change with each post

Can be globally accessed also

Where are Custom Fields used?

Yoast SEO fields

Genesis framework: different visual layouts to select from

Themify: color boxes to select different color themes

Why Custom Fields?

Structuring content is more important than ever

Take site out of WYSIWYG box Chunks vs blobs: break content into manageable blocks

Serve together on one page, or divide & send to mobile, api, anywhere else

COPE: Create once, publish everywhere

Good experience for content publishers

Why Advanced Custom Fields?o Core custom fields interface is

confusing, not user friendly

o Interrupts workflow

o Lots of work to customize and limit

Conditional Statements

In Your Theme: Best practice to display CF’s with

a conditional

Can display certain support elements only if field exists

Add class to body

Display alternate data

Only display posts with a specific custom field

In the Admin: Setting expiration date for posts

Page-specific content types

Extended publish statuses

Conditionals Demo!

Admin UX Demo!

Content ModelingA process to describe all your types of data and the relationships between them

Audit EVERYTHING

Wireframe every pageSeriously, every page.

You will probably find:

There are more pages than you thought

Maybe even whole sections

Navigation issues

Layout limitations

Plan your custom fields & relationships right on the page, including id’s

Use standard naming conventions

Use language the user will understand

Identify unique blocks

That require special tags

Special output

Shared content across the site

But be realistic.

Draw a balance between strictly structured content, and freedom for the author to enter all the content they need

We don’t want to make the author bend their content to fit your structure

No model survives first contact with real content.

Potential Issues

ACF Plugin must be installed for metadata fields to show Can export as PHP for mu_plugins

wp_search: only searches the_content() – no custom fields Search WP & Faceted Search plugins

rss: only feeds the_content()

Localization plugins: only translates the_content() (typically)

ACF text output is not escaped like native WordPress functions https://github.com/10up/secured-advanced-custom-fields
