Forum OpenACS Q&A: How to use double index.adp?

Posted by H. shefaat on 09/18/02 04:13 PM

Hi, I m facing withe following problem: We want to run a multilangauge portal on openacs4.. For one it works very fine. Then we would like to put an oothe language front page. I tried to write a new index.adp (index_e.adp for English, index_i.adp for Italien ..). But the proble is this side is not shown by aolserver without error message!!!
1)Is it possible to use differnt index.adp, index_x.adp,..?
2) If not how can I have differnt front page for different language? Thanks in advance

You probably want to look at Collaboraid's Internationalization Effort over at http:// www.collaboraid.biz/extranet/i18n/blog/.

In general, if you want to return different ADPs, make sure to set up "index.tcl" because that will be sourced first. Then, use whatever logic you need in index.tcl to return the right ADP file, which you can do using:

ad_return_template <template_name>

where <template_name> is index_e or index_s.

Thanks fo code, Unforunatly I get this error after writing the code:

The error message is:

    (procedure "ad_return_template" line 1)
    invoked from within

    invoked from within

Any idea what is wrong?

The correct syntax for your case is

ad_return_template index_e

You can search for procedure documentation on your server at youservername.com/api-doc/ or at http://dev.openacs.org/api-doc/ (although this is for the version running at dev.openacs.org and may be slightly out of date if you have a current cvs checkout).

Thanks Jeff,
Aolserver use now only index_e. what I want is to use index as default. 


After clicking on a button (for instance English falg) then the server hat to go to index.e and show this page. 


So I need to use double index 1) index for default  2)index_e for English.

I suspect you will have to learn some more TCL :) If you let them set their language (with a cookie or something) like this

set lang en
ad_return_template "index_$lang"

you could get the language form the accept-language header sent by the browser. Here is a bad hacky example of that:

set lang [lindex [split [ns_set iget [ns_conn headers] accept-language] "-,;"] 0]

Thank you Jeff,
you are right I m not a TCL/TK programmer but I think it could be possible to set up these first things.
Anyway where I have to put the code?
set lang en ad_return_template "index_$lang"
This code in index ?
set lang [lindex [split [ns_set iget [ns_conn headers] accept-language] "-,;"]
And this code alo in index?
So as you can see I dont have a lot of experience with this index, so please tel me what is exactly to do.
Thanks

you could put the code in index.tcl (or lots of other places).

I think you might need to spend some time reading about
programming though since I don't think given where you are
starting from you will make much progress posting.
