The minimum structure you need to know before building modules, skins, layouts, and themes on Zittme.

Relationship with Rhymix

Zittme is a GPL v2 engine forked from Rhymix 2.1.35. From a third-party development perspective, compatibility is what matters.

• The core namespace is Zittme\. Rhymix\ remains as a compatibility alias, so existing Rhymix modules that call Rhymix\Framework\... keep working as is.
• Write new code against Zittme\.
• Most modules, skins, and layouts built for Rhymix work without changes. Zittme-specific features (theme packages, repeat fields, the responsive flag) are designed so that installing them on Rhymix simply ignores them without errors.

Folder structure

Request flow

Every request enters through index.php, and two values decide which code runs.

• mid: the module instance name. Each "one board, one page" created in the sitemap is a mid. It becomes the first segment of the address (/board, /manual).
• act: the name of the action to run (dispBoardContent, procBoardInsertDocument). Only actions declared in the module's conf/module.xml run.

Action names follow a convention.

To make clean addresses such as mid/document_srl or mid/write, declare routes on actions. This is covered in Building modules.

Database

You don't write SQL directly. Queries are declared in XML files (queries/*.xml) and run with executeQuery('module_name.query_name', $args). If you also declare tables in XML (schemas/*.xml), the core creates them when the module is installed. For details, see Query XML.

Templates

Screens are drawn with template files (HTML). Two generations of syntax coexist.

• v2 (recommended): @version(2) on the first line of the file. @if / @foreach / {{ }} style
• v1 (legacy): cond="", loop="" attribute style. For compatibility with existing resources

Build new resources with v2. See Template syntax v2.
