Allow user to choose language V1.3

Question

I saw instructions for this for V1.2 I am wondering if this will work for V1.3?

Comments

I verify it at new V1.3 environment(My environment updated from old version). Please wait for a while.

Answer 1

Below code is language + theme changer for V1.3

  $languagecode=$qa_lang;

Source: qa-include/qa-page.php

find:

$themeclass=qa_load_theme_class(qa_opt('site_theme'), $qa_template, $qa_content, $qa_request);

replace:

if (!isset($qa_theme)) // otherwise get option

  $qa_theme=qa_opt('site_theme');

$themeclass=qa_load_theme_class($qa_theme, $qa_template, $qa_content, $qa_request);

After switch language, url allways display as old link, so language is also the default language

Demo:
http://www.joomla178.com/ask/?&qa_lang=zh-TW
http://www.joomla178.com/ask/?&qa_lang=zh

Solved:

Find code:

$requestpath=implode('/', $requestparts);

Replace:

$qa_lang=qa_get('qa_lang'); // get from URL parameter if possible
$requestpath=implode('/', $requestparts).'&qa_lang='.$qa_lang;

Hi Sama, Will this work with v. 1.7?

Answer 2

It doesn't work 

Fatal error: Call to undefined method qa_html_theme::changer()

Has anyone implemented this on V1.3?

Answer 3

It would be awesome to have a multilingual setup out of the box or trough a plugin. I'm always reluctant to change the code - it's always a hassle after each update.

this worked for me (v 1.6.3).

i added below two lines:
$qa_lang=qa_get('qa_lang'); // get from URL parameter if possible
$params['qa_lang'] = $qa_lang;

before:
$requestpath=implode('/', $requestparts);
