# Acai CMS — Project Instructions

This is an Acai CMS website project. Follow these instructions when working with the codebase.

## Environment

- The site runs in Docker. The public URL is the project's domain (e.g. `https://username_domain.forge.acaisuite.com/`)
- You can make HTTP requests to test pages, APIs, or form submissions using the project's public URL
- If you need to inspect the live site, use browser tools (Playwright MCP) or HTTP requests to the project URL
- **NEVER use localhost:8080** — that does not resolve in this environment. Always use the project's actual URL.

## Key Concepts

### Modules (`template/estandar/modulos/`)
Visual components that the site builder uses. Each module is a self-contained unit with its own template (Twig + Acai attributes), CSS, and JS. Modules are placed on pages via the drag-and-drop builder. The editable file is always `index-base.tpl`.

- Include other modules: `<module_id :param1="value1"></module_id>`
- Each module instance gets a unique `section_id` variable for anchors/scoping
- Use `interno` variable to detect CMS editor mode vs public view

See [docs/modular-system.md](docs/modular-system.md) for detailed rules.

### Pages
Every record with an `enlace` field is a page. Pages are either **Builder** (modular) or **Standard**:

- **Builder**: `controlador` = `cms/lib/plugins/builder_saas/controlador.php` — content via modules
- **Standard**: `controlador` = `cms/lib/plugins/builder_saas/controlador_tabla.php` — content in record fields

**Critical**: Never change `enlace` or `controlador` of existing pages unless explicitly asked.

See [docs/pages-and-records.md](docs/pages-and-records.md) for full details.

### General Sections
Database-backed templates (headers, footers, record views) that use the `thisrecord` variable to access record fields. They use the same Twig + Acai attribute engine as modules.

- Upload fields return arrays: `thisrecord.image[0].urlPath`
- Foreign keys use `_num` suffix: `category_num`

See [docs/modular-system.md](docs/modular-system.md) for details.

### Hooks (`hooks/`)
PHP files that execute server-side logic. Triggered by:
- Twig filter: `'hooks/module_id/' | hook({param: value})`
- HTML tag: `<hook result="var" endpoint="/hooks/module_id/" :param="value"></hook>`
- JavaScript: `CmsApi.hook('/hooks/module_id/', {param: value}, callback)`
- Form action: via `c-form` attribute

There are two valid hook locations:
- Global hooks in `hooks/hooks.<hook-id>.php` for reusable/shared server-side logic
- Module-specific hooks in `template/estandar/modulos/<module-id>/hook.php` for logic owned by a single module

How to reference them:
- Global hook `hooks/hooks.calcular_precio.php` -> endpoint `/hooks/calcular_precio/`
- Module hook `template/estandar/modulos/hero_banner/hook.php` -> endpoint `/hooks/hero_banner/`
- Module hook `template/estandar/modulos/buscadorapartados_hjd8s/hook.php` -> endpoint `/hooks/buscadorapartados_hjd8s/`

Rule of thumb:
- If the logic is only used by one module, prefer that module's `hook.php`
- If the logic will be reused by several modules/pages, create a global hook in `hooks/`
- Return arrays from hooks; do not use `echo json_encode(...)` or `exit`

See [docs/hooks-and-api.md](docs/hooks-and-api.md) for usage.

## Database Access

When the site is running in Docker, you can connect to the database:

- **Host:** `127.0.0.1`
- **Port:** Check `.docker/docker-compose.yml` for the mapped port (usually 3307+)
- **Credentials:** Read from `.docker/.env`:
  - `DB_USERNAME`
  - `DB_PASSWORD`
  - `DB_DATABASE`

```bash
docker exec -it dw-<project-name>-db mysql -u root -p<password> <database>
```

**Important:** Table names in CmsApi/Twig do NOT use the `cms_` prefix. The primary key is always `num`, never `id`.

## Acai Core (web-base)

The project workspace contains only the **customization layer** (modules, hooks, schemas, uploads). The CMS core (routing, rendering engine, admin panel, APIs) lives in a separate directory called **web-base** that is mounted as a Docker volume.

The web-base path can be obtained via: `GET http://localhost:9090/api/web-base-path`

Do NOT modify web-base files — they are shared across all projects.

## Critical Rules

1. **Before working with any area (hooks, modules, templates, CSS/JS, etc.), read the corresponding documentation in `docs/` first.** Do not guess or assume — always consult the docs before taking action.
2. **NEVER use `mkdir` to create directories.** Instead, use `acai-write` to create the first file inside the directory — this creates parent directories automatically. For example, to create a new module, directly write the `index-base.tpl` file.
3. Only edit `index-base.tpl` in modules — `index.tpl`, `index-twig.tpl`, and `builder.json` are auto-generated
4. Editing or creating any `index-base.tpl` through `acai-write` or `acai-line-replace` triggers automatic compilation. `compile_module` is only for manual recovery when you need to force a recompile without changing the file.
5. `script.js` and `style.css` are static files — do NOT use Twig syntax inside them. Pass dynamic values from `index-base.tpl` via `data-*` attributes.
6. Use Twig **filters** (with `|`), never Twig functions
7. Table names without `cms_` prefix everywhere
8. Primary key is `num`, never `id`
9. Upload fields are arrays — access with `[0].urlPath`
10. Tailwind CSS as primary styling, custom CSS scoped with BEM when needed
11. Twig concatenation uses `~` operator: `'value=' ~ variable`
12. `enlace` (link) fields already include slashes — **NEVER modify an existing enlace** unless explicitly asked
13. **NEVER modify the `controlador` field** of existing records — it defines whether a page is Builder or Standard

## MCP Tools

This project has MCP tools for managing modules, records, media, and more. **Before starting any task, consult the tools reference for the correct workflow.**

See [docs/mcp-tools-reference.md](docs/mcp-tools-reference.md) for the complete list of available tools and step-by-step workflows.

Key workflows:
- **Create module**: Read [docs/module-creation-guide.md](docs/module-creation-guide.md) first → create files with `acai-write` / refine with `acai-line-replace` → automatic compile on `index-base.tpl` → `add_module_to_record` (returns sectionId) → `set_module_config_vars` (returns uploadFields) → images via uploadFields. Use `compile_module` only if you need a manual recompile without editing the file.
- **Edit module**: `acai-view` → `acai-line-replace` (or `acai-write` for full rewrites) → automatic compile on `index-base.tpl`
- **Add images**: use `uploadFields` from `set_module_config_vars` response → `upload_record_image`
- **Generate images**: `generate_image` → `upload_record_image` with returned URL
