Wp pods

Pods Framework

Pods manages WordPress custom content types (CPTs), taxonomies, and custom database tables (Advanced Content Types). It is the primary data structure layer for the U of Digital site — all custom content models, field definitions, and relational data flow through Pods.

When to use

• Creating or modifying custom post types or taxonomies
• Working with Pods custom fields (reading, writing, seeding, syncing)
• Writing PHP that queries Pods-managed data (always declare ACT vs postmeta first)
• Setting up bi-directional relationships between content types
• Exposing Pods fields to the WordPress REST API or Abilities API
• Integrating Pods with Gravity Forms (pods-gravity-forms add-on)
• Advising an AI assistant on the correct query approach for a given Pod

⚠️ Critical — always declare storage type to AI agents

Before writing any code that touches Pods data, declare to your AI assistant which storage type the Pod uses:

Storage type	DB location	Query method
postmeta (default)	wp_postmeta	WP_Query, get_post_meta(), pods_field()
ACT (Advanced Content Type)	wp_pods_<name> (custom table)	pods_field() only — never get_post_meta()

Rule: Never use get_post_meta() on an ACT Pod — it queries the wrong table and silently returns nothing.

Always tell your AI assistant:
"This Pod stores data as an ACT (custom table wp_pods_program)"
OR
"This Pod uses standard wp_postmeta storage"

Procedure

1) Install

# Free on WordPress.org
wp plugin install pods --activate

# Verify
wp plugin status pods

2) ACT vs postmeta — the critical decision

When creating a new Pod, choose storage type:

• postmeta (default): best for standard CPTs with <50 fields. Compatible with most WP tools.
• ACT: best for high-volume data, complex relational queries, many fields. Custom table = better performance, less wp_postmeta bloat.

Declare this in any file that handles the Pod's data:

/**
 * Pod: 'program'
 * Storage: ACT (custom table: wp_pods_program)
 * Query: Use pods_field() — NOT get_post_meta()
 */

3) Correct field access patterns

// ✅ Correct for BOTH storage types
$value = pods_field('program', $post_id, 'start_date');

// ✅ Using the Pods object
$pod = pods('program', $post_id);
$value = $pod->field('start_date');

// ❌ WRONG for ACT pods (silently returns nothing)
$value = get_post_meta($post_id, 'start_date', true);

// ❌ WRONG for ACT pods (wrong table)
global $wpdb;
$value = $wpdb->get_var("SELECT start_date FROM wp_postmeta WHERE post_id=$post_id...");

4) Relationship fields — use IDs, not titles

When seeding or syncing relationship fields via AI agents:

// ✅ Correct — raw arrays of IDs
pods_save('program', [
    'id'              => $program_id,
    'related_courses' => [42, 87, 103],  // IDs only
]);

// ❌ Wrong — text titles break relational integrity
pods_save('program', [
    'related_courses' => 'Course A, Course B',
]);

5) Expose Pods to REST API

add_action('init', function() {
    register_rest_field('program', 'start_date', [
        'get_callback'    => fn($obj) => pods_field('program', $obj['id'], 'start_date'),
        'update_callback' => fn($val, $obj) => pods_save('program', ['id' => $obj->ID, 'start_date' => $val]),
        'schema'          => ['type' => 'string', 'format' => 'date'],
    ]);
});

6) Pods + Gravity Forms integration

The pods-gravity-forms add-on links form submissions directly to Pods data:

wp plugin install pods-gravity-forms --activate

• Maps Gravity Forms fields to Pod fields on submission
• Auto-creates or updates Pod items from form entries
• Supports relationships — maps multi-select fields to related Pod items
• Docs: https://github.com/pods-framework/pods-gravity-forms

7) Exposing to WordPress Abilities API

// Allow LLM workflows to read/write Pod data via Abilities API
wp_register_ability('program.read', [
    'description' => 'Read program custom fields',
    'callback'    => fn($args) => pods_field('program', $args['id'], $args['field']),
    'schema'      => ['id' => 'integer', 'field' => 'string'],
]);

Context for AI code generation

Always include this in any prompt where you want code that touches Pods data:

Context: This Pod named 'program' uses ACT storage (custom table wp_pods_program).
Use pods_field('program', $post_id, 'field_name') — never get_post_meta().
For relationships, always pass raw integer ID arrays, never text labels.
