[Typo3-dev] TS dynamic path to html template

[Gernot Brandl]

Hi,
this is a newbe question:)

In a template i try to fill a subpart (###DYN_CONTENT###) with the content 
of a html template.

The actual tamplate file i want to include depends on the value of a column 
in the pages table (this column is provided by an extension i wrote. The 
user selects which template file he wants to use while creating a new page).

I declared a TS Constant which holds the path-prefix to these selectable 
templatefiles:

 templatePathPrefix = fileadmin/content_templates/content/

as described above the filename of the template is 
'field:tx_sstplselector_content_tpl'

so the actual path to the template file is generated by concatenating 
templatePathPrefix with field:tx_sstplselector_content_tpl'.

How can i do this within TS??

Thanks in advance
Gernot

My Code so far:

content.dynContent = TEMPLATE
content.dynContent {
    template =  FILE
    # HERE IS THE PROBLEM
    template.file = {$templatePathPrefix}field:tx_sstplselector_content_tpl
    workOnSubpart = DOCUMENT_BODY
}
content.mainTemplate.subparts.DYN_CONTENT < content.dynContent
