Posts and pages are WordPress defaults. Real sites need more: project budgets on portfolio items, phone numbers on directory entries, specs on product pages, event dates on listings. That extra data lives in custom fields — and for years, adding them meant code, hooks, or plugins that felt built for developers, not editors.
The good news: you can run structured content in WordPress today without writing a line of PHP. You need a clear content model, the right field types, and a workflow your team can follow.
What are custom fields?
Custom fields are extra pieces of data attached to a post, page, or custom post type. Examples:
- Portfolio: Client name, project URL, year, budget range
- Team directory: Job title, email, LinkedIn URL
- Recipe: Prep time, servings, difficulty
- Real estate: Price, bedrooms, square footage
You define the fields once. Editors fill them in. Your theme or shortcodes display them on the front end.
Custom post types: when posts are not enough
Sometimes the problem is not missing fields — it is the wrong content type. “Team member” is not really a blog post. “Project” is not a page.
A custom post type (CPT) gives you a dedicated section in the admin (Projects, Team, Testimonials) with its own fields and templates. The best setups let you register CPTs from the admin without code.
Tools like BooField combine a visual field builder with a CPT builder, so one plugin covers both problems.
Choosing the right field types
Match the field to the data:
| Data | Field type |
|---|---|
| Short label | Text |
| Long description | Textarea |
| Price, quantity | Number |
| Yes / no | Checkbox |
| Contact email | Email (validated) |
| External link | URL |
| Fixed options | Select dropdown |
Avoid over-engineering. Ten well-chosen fields beat thirty vague ones.
Editing in Gutenberg
Your fields should appear where editors already work — inside the block editor — not on a separate screen they forget to open. Gutenberg-native field editing means content and meta stay in sync and training time drops.
Displaying fields on the front end
You need a predictable way to output values: shortcodes are the most portable. Example mental model:
→ outputs the escaped value wherever you place it.
Secure output matters. Email fields should not become spam magnets. URLs should be escaped. Numbers should not break layout.
Multilingual and duplication workflows
If you run a multilingual site, field values need translation too — not just post titles. BooTranslate integrates with BooField so custom content can follow your language setup.
When you duplicate a post as a template, fields should copy with it. BooDuplicate handles meta and taxonomies so cloned drafts are actually usable.
Common mistakes
- Too many fields upfront — start with five, add more when editors ask.
- No naming convention — use
client_name, notfield_7. - Hiding fields from editors — if they cannot see it in Gutenberg, they will not fill it in.
- Building CPTs in code when the client will manage the site alone — admin-based CPTs age better.
Bottom line
Custom fields turn WordPress from a blogging tool into a flexible CMS. You do not need a developer on retainer to get started — you need a focused plugin, a simple content model, and shortcodes you can trust.
