Introduction to Headless WordPress

Headless WordPress uses WordPress as a backend for content management while building the frontend from scratch with HTML, CSS, and JavaScript. This approach gives more control, unique designs, and the ability to charge higher fees like $5,000 per project, avoiding generic page-builder sites. Key takeaway: Focus on creating custom post types and fields in WordPress, then fetch data via REST API for dynamic frontend rendering, applicable to sites like real estate listings. Ask AI: Introduction to Headless WordPress

Setting Up WordPress Backend

Install WordPress on a hosting provider like Hostinger for cost savings (up to 75% off with coupon MR WEB for extra 10%). Use the onboarding to set up without templates. Install plugins: Custom Post Type UI (from WebDevStudios) and Advanced Custom Fields (from WP Engine). Deactivate unnecessary default plugins. Key takeaway: Choose plans based on site needs (e.g., Premium for up to 100 sites), and enable free SSL and domain. Ask AI: Setting Up WordPress Backend

Creating Custom Post Types

Use CPT UI to add a post type like "properties" (plural label: Properties, singular: Property). Set public to true, show in REST API to true, has archive to true, and custom rewrite slug to "properties". Support title, editor, featured image, and custom fields. Attach taxonomies if needed. Key takeaway: Ensure REST base slug is "properties" for API querying. Ask AI: Creating Custom Post Types

Adding Custom Fields with ACF

Create a field group "Property Details" assigned to the "property" post type. Add fields: price (number), bedrooms (number), bathrooms (number), area (number), gallery (image, or gallery in pro version), map embed (Google Maps). Key takeaway: Enable REST API exposure in ACF settings to fetch fields via API. Ask AI: Adding Custom Fields with ACF

Creating Custom Taxonomies

Add taxonomies like "locations" (plural: Locations, singular: Location) and "property types" (plural: Property Types, singular: Property Type), attached to "properties". Set public and show in REST API to true. Add terms like villas, bungalows for types, and Dublin, Cork for locations. Key takeaway: Disable default categories/tags if using custom ones to keep the menu clean. Ask AI: Creating Custom Taxonomies

Adding Sample Properties

Create a new property with title, ACF fields (price, bedrooms, etc.), featured image, taxonomies (e.g., villa type, Dublin location), and publish. Key takeaway: Use real data like address, price, and Google Maps iframe for completeness. Ask AI: Adding Sample Properties

Building Frontend from Scratch

Use VS Code to create folders (js, css) and files like property.html, category.html. In property.html, add a div with id "property" and link to property.js. In property.js, fetch data via REST API (e.g., https://cms.example.com/wp-json/wp/v2/properties?slug=slug-name), parse slug from URL, handle errors, and render title, content, ACF fields, taxonomies, and image. Add style.css for styling.

// Example in property.js
async function getPropertyBySlug(slug) {
  const response = await fetch(`https://cms.example.com/wp-json/wp/v2/properties?slug=${slug}`);
  const data = await response.json();
  return data.length > 0 ? data[0] : null;
}

Key takeaway: Use document.getElementById to update elements dynamically; debug issues like missing REST exposure. Ask AI: Building Frontend from Scratch

Integrating with Pre-Made Templates

Download free HTML templates (e.g., real estate from w3layouts.com). Open in VS Code, go live. For pages like property-single.html, replace static content with IDs (e.g., property-title, property-description). Create JS file to fetch via REST API, update elements like title, location, description, price, image. Adjust layout, e.g., set hero background dynamically. Key takeaway: Add script tag before to load JS; use ACF.description for content. Ask AI: Integrating with Pre-Made Templates

Selling the Service

Position as a custom-built solution (not "WordPress website") for speed, ease, and performance. Highlight: tailored design, self-updates via simple backend, faster loading for SEO, scalability, no plugin dependency, clean code, future app integration. Pitch as web developer offering results-oriented sites. Key takeaway: Train clients in 10 minutes; emphasize separation of design and content. Ask AI: Selling the Service
