System objectsAvailable from FirstSpirit Version 4.0

Using system objects

System objects can be used to access information, data and objects within the templates. This is useful, for example, in the generation and creation of a preview. Such information can be, for example, the starting time of the generation, the ID of the section or the page or the language currently being generated.

System objects are always context-dependent. Several system objects are available in all contexts, others in a specific context only.

Expressions can be applied to system objects.

The return value of a system object is an object or a data type (cf. Data types).

In general system objects can be read-accessed only. However, there are several methods which can also modify system objects or can affect the system performance. These include, e.g. the suppression of generation of a page in a page template (#global.stopGenerate).

Using system objects

The following table gives an overview of the contexts in which a specific system object is available and what it can be used for:

Invocation of system objects

System objects can be invoked wherever method invocations can be used:

Each system object begins with the hash sign # and is extended by the respective name of the system object. Different methods can be invoked depending on the type of system object.

Syntax:

$CMS_VALUE(#NAME[.METHOD])$

E.g.:

$CMS_IF(#global.preview)$
Preview
$CMS_ELSE$
No preview
$CMS_END_IF$

If a preview is generated for the current page Preview is output - otherwise No preview.
