Entering and structuring TypoScript templates¶
At its most basic, TypoScript is entered manually in both the "Constants" and "Setup" fields of template records (which are stored in the database in table "sys_template").
If the "t3editor" system extension is not installed or has been disabled via configuration options, the "Constants" and "Setup" fields will be normal multi-line text fields.
In both the "Constants" and "Setup" fields, the INCLUDE_TYPOSCRIPT syntax can be used to include TypoScript contained inside files.
Apart from this, it is also possible to include other TypoScript template records (in the field called "Include Basis Template") and TypoScript provided by extensions (in the field called "Include static (from extensions)").
Included templates can themselves include other templates.
With all those inclusions, it may happen that you lose the overview of the template structure. The "Template Analyzer" provides an overview of this structure. It shows all the templates that apply to the currently selected page, taking into account inclusions and inheritance along the page tree.
Templates are taken into consideration from top to bottom, which means that properties defined in one template may be overridden in templates considered at a later point by the TypoScript parser.
In the Template Analyzer, you can click on any listed template to view the content of its "Setup" and "Constants" fields.
The line numbers are compiled from the first template to be included, which is why the numbers are so high.
