|
|
@abstract Storage Objects: Everything to store and retrive the eTemplates.
|
|
@discussion eTemplates are stored in the db in table 'phpgw_etemplate' and gets distributed
|
|
@discussion through the file 'etemplates.inc.php' in the setup dir of each app. That file gets
|
|
@discussion automatically imported in the db, whenever you show a eTemplate of the app. For
|
|
@discussion performace reasons the timestamp of the file is stored in the db, so 'new'
|
|
@discussion eTemplates need to have a newer file. The distribution-file is generated with the
|
|
@discussion function dump, usually by pressing a button in the editor.
|
|
@discussion writeLangFile writes an lang-file with all Labels, incorporating an existing one.
|
|
@discussion Beside a name eTemplates use the following keys to find the most suitable template
|
|
@discussion for an user (in order of precedence):
|
|
@discussion 1) User-/Group-Id (not yet implemented)
|
|
@discussion 2) preferd languages of the user (templates for all langs have $lang='')
|
|
@discussion 3) selected template: verdilak, ... (the default is called '' in the db, not default)
|
|
@discussion 4) a version-number of the form, eg: '0.9.13.001' (filled up with 0 same size)
