Admin Settings & Configuration

Flow ID: AD-13 Module(s): settings Complexity: Medium Last Updated: 2026-04-10

Business Overview

All platform configuration is stored in a database-backed registry (registry table) with a group/key/value/language structure. The Registry library provides get/set/delete with PSCache caching, encryption for secrets via the CI Encryption library, method chaining, and pipe-delimited array storage. Five settings controllers manage 50+ integration providers across 20+ admin pages, organized into the ecommercen/settings/ HMVC module.

The settings system is the central nervous system of the platform -- almost every feature (payments, feeds, analytics, AI, notifications, SSO, loyalty, search, and third-party integrations) is configured through registry values that are read at runtime.

API Reference

Admin Panel Routes

All settings routes are session-based admin panel pages (no REST API endpoints).

Code Flow

Registry Read/Write Pattern

Every settings controller follows the same pattern:

Adv_settings::{page}()
  |-- POST submission check
  |     |-- Run validation rules
  |     |-- If valid:
  |     |     |-- registry->setValue($group, $key, $value, $lang?, $encrypted?)
  |     |     |     |-- Updates in-memory data array
  |     |     |     |-- Calls registry_model->set_regval()
  |     |     |     |     |-- Checks if (reggroup, regkey, lang) exists
  |     |     |     |     |-- If exists: UPDATE regval
  |     |     |     |     |-- If not: INSERT new row
  |     |     |     |     \-- Encrypts value if $encrypted=true via Encryption library
  |     |     |     \-- Returns $this (method chaining)
  |     |     \-- redirect back to same page
  |-- GET display:
  |     |-- registry->value($group, $key, $lang?, $encrypted?)
  |     |     |-- Looks up in-memory array: data[$group][$key][$lang]
  |     |     \-- Decrypts if $encrypted=true
  |     |-- Merge into render array
  |     \-- Load view

Registry Initialization (On Every Request)

Registry::__construct()
  |-- Load registry_model + pscache + encryption
  |-- pscache->model('registry_model', 'all', [])
  |     |-- Check file cache for 'registry_model_all_[]'
  |     |-- On miss: registry_model->all() -> SELECT * FROM registry
  |     \-- Cache result
  |-- parseDb($data)
  |     |-- Build nested array: data[$reggroup][$regkey][$lang] = $regval
  |     \-- Empty lang mapped to 'BASE' constant

Registry Live Refresh

Registry::live()  [called in Adv_admin_controller constructor]
  |-- pscache->updateCache('registry_model', 'all', [])  [invalidates cache]
  |-- pscache->model('registry_model', 'all', [])  [re-fetches from DB]
  \-- parseDb($data)  [rebuild in-memory array]

Encrypted Values Flow

Registry::setValue('SOCIAL_AUTH', 'GOOGLE_CLIENT_SECRET', $value, '', true)
  |-- registry_model->set_regval(..., $encrypted=true)
  |     |-- encryption->encrypt($regval) [CI Encryption library]
  |     \-- Store encrypted ciphertext in DB

Registry::value('SOCIAL_AUTH', 'GOOGLE_CLIENT_SECRET', '', true)
  |-- Read raw (encrypted) value from in-memory array
  \-- encryption->decrypt($value) -> plaintext

Caching Architecture

                    +-----------+
                    | PSCache   |  (file-based, L2 cache)
                    +-----------+
                         |
  Admin requests:        |           Frontend requests:
  Registry::live()       |           Registry reads from
  forces refresh --------+---------- pre-loaded in-memory array
                         |
                    +-----------+
                    | registry  |  (MySQL table)
                    +-----------+

The entire registry table is loaded once into PSCache, then parsed into an in-memory nested array. Admin controllers call Registry::live() to force a refresh on each admin page load. Frontend controllers rely on the cached version.

Data Model

`registry` Table

Column	Type	Description
`id`	INT(11) PK AI	Record ID
`reggroup`	VARCHAR(150)	Configuration group (e.g., `ESHOP`, `PAYPAL`, `SITE`)
`regkey`	VARCHAR(150)	Configuration key within group
`regval`	TEXT	Value (plaintext or encrypted ciphertext)
`lang`	VARCHAR(2)	Language abbreviation (empty string for non-localized values)

Indexes: reggroup, regkey, (regkey, lang), (reggroup, regkey, lang) -- the last is a covering index for the upsert pattern.

Storage Patterns

Pattern	Example	Storage
Simple value	`setValue('ESHOP', 'PAYMENTS_ACTIVE', '1')`	`regval = '1'`, `lang = ''`
Per-language	`setValue('SITE', 'TITLE', 'My Shop', 'el')`	`regval = 'My Shop'`, `lang = 'EL'`
Encrypted	`setValue('PAYPAL', 'PASSWORD', $pw, '', true)`	`regval = encrypted_ciphertext`, `lang = ''`
Array	`setArray('PAYWAY', 'METHODS', '', ['cod','card'])`	`regval = 'cod

Configuration

File	Description
`application/config/auth.php`	Auth provider flags, hash type, static users
`application/config/email_groups.php`	Defines available email group names for SMTP settings
`application/config/ai_content_generation_prompts.php`	Defines entity/field structure for AI prompt settings
`application/config/emailViews.json`	Email template configuration for the email viewer
`ecommercen/helpers/registry_helper.php`	Helper functions for registry access outside controllers

Environment Variables

The registry itself has no direct environment variable dependencies, but many settings pages reference .env values via env() calls for initial/fallback values. The encryption key used for encrypted registry values is configured via the CI Encryption library config.

Client Extension Points

Settings controllers extend Admin_c -- client repos can override any settings controller by placing a same-named file in application/controllers/.
New registry groups can be created at any time by simply calling setValue() with a new group name -- no schema changes needed.
Encryption keys are per-installation (from CI config), so encrypted values are not portable between environments.
Custom settings pages can be added by creating new controllers in the settings module (in client repos, in application/controllers/), using the same Registry read/write pattern.
Registry helper (ecommercen/helpers/registry_helper.php) provides functions for registry access in contexts without controller access.

Business Rules

Encryption for sensitive fields: API keys, secrets, and passwords use the 5th parameter true on setValue()/value() to encrypt/decrypt via the CI Encryption library. Encrypted values are stored as ciphertext in the DB.
Multi-language support: The lang column separates per-language values. Empty string ('') is mapped to the constant BASE internally. Language abbreviations are auto-uppercased.
Role-based access: General settings require ADVISABLE + ADMIN roles. Social auth settings are restricted to ADVISABLE only. The only_advisable() page has an inner guard: SMS limits are only writable by ADVISABLE users.
Array values: Stored as pipe-delimited strings (e.g., val1|val2|val3). Use setArray()/getArray() for transparent serialization.
Cache invalidation: Registry::live() invalidates PSCache and re-reads from DB. Called on every admin page load. Frontend reads use the cached version without refresh.
Upsert pattern: Registry_model::set_regval() checks if a row exists for (reggroup, regkey, lang) and either UPDATEs or INSERTs. This prevents duplicate entries.
No validation on values: Registry stores raw string values. Type casting and validation happen in the controller layer before calling setValue().
Logo upload: The index() method handles logo file upload separately via updateLogo() and stores the filename in GLOBAL.LOGO.

Registry Usage Statistics

The settings system manages 77 unique registry groups across all settings controllers (Adv_settings.php, AdvSocialAuthSettings.php, AdvSocialLinksSettings.php, AdvFavicons.php, AdvEmailViewer.php).

Production scale: Live databases contain 94 unique registry groups with 890+ registry entries in total. The 17 additional groups beyond what is visible in settings controllers are created by runtime code (jobs, libraries, integrations) via setValue() calls, or by client-specific customizations. The inventory table above covers the 77 controller-managed groups plus 11 additional groups discovered from production data and 4 from code analysis.

Top 30 Registry Groups by Usage Frequency (Codebase-Wide)

This table shows how frequently each registry group is read via value() across all ecommercen/ PHP files. Higher counts indicate groups that are critical runtime dependencies -- modifying these groups has broader impact.

`COMPANY_PHONE`	index	Company phone number
`PAYMENTS_ACTIVE`	index	Enable/disable payments
`TRANS_COST_LIMIT`	index	Free shipping threshold
`LIMIT_ON_PRODUCTS`	index	Products per page limit
`DEFAULT_CURRENCY`	index	Default currency code
`SLUG_TO_GREEKLISH`	index	Transliterate slugs to Greeklish
`MINIMUM_CART_TOTAL_FOR_PAID_AT_STORE`	index	Minimum cart for store pickup
