3. MCP Server Reference › 3.3 Engine › Templates › engine_html_add

Creates a module’s template in a template group. If the module’s folder does not yet exist in this group, it is created. The template’s body is written by engine_html_save.

The Right

“Direct access → Development → Modify data” (AGENT_ENGINE_DEV_WRITE).

Parameters

Parameter	Type	What it is
`path`	string	the path of the new template: `templates/<group>/units/<module>/<template>.htm`

The template appears only in the group named. Added to the main group, it works in the rest as well: where there is no file with such a name, the engine takes the template from the main group. A copy of its own is needed by a group with a different layout.

The Answer

{"path": "./../templates/default/units/melbis_cataloge/extra.htm"}

Refusals

Answer	When
`path goes as templates/<group>/units/<module>/<template>.htm`	the path is wrong: not inside `templates/<group>/units/<module>/` or without `.htm`
`Template already exists: <name>`	a template with such a name already exists in this group
