[HOWTO] Upgrade from 1.x/Polyglot to qTranslate 2.x

[Qian Qin]

As you might know, qTranslate 2.0 is quite different from qTranslate 1.x. Here is a short (incomplete) list of things that changed:

• New Language tags:

  Code: Select all

  <!--:en--><!--:-->

  instead of

  Code: Select all

  [lang_en][/lang_en]

• Tags/Categories/Link Categories are not using language tags anymore

So these two things will be needed to be updated to make qTranslate 2.0 work. qTranslate will convert old language tags to new ones for you. All you need to do is to go the the "Languages" Settings page, click on "Show" for Advanced Options and click on the link for converting your database. See the attached screenshot for details.
For the second part, you will need to manually update all your categories, tags and link categories.

[*]Tags/Categories/Link Categories are not using language tags anymore[/*]

What? Does this mean all tag and cateogry translations will be lost forever? I would rather not upgrade if it's going to break all of these features.

[miqrogroove]

I figured out that the tags and categories can still be translated.

But there is a big problem! The translations only appear in the sidebar. The "Tags" and "Posted In" section of the posts are always in English now

I tried changing themes too and they all show English tags and categories in the posts.

Holy hell! It took me 5 hours to figure this out.

in wp-includes/taxonomy.php function wp_get_object_terms()

find

Code: Select all

   return $terms;

replace with

Code: Select all

   $terms = apply_filters('wp_get_object_terms', $terms);
   return $terms;

in qtranslate_hooks.php

find

Code: Select all

add_filter('get_terms',                  'qtrans_useTermLib',0);

replace with

Code: Select all

add_filter('get_terms',                  'qtrans_useTermLib',0);
add_filter('wp_get_object_terms',         'qtrans_useTermLib',0);

Greetings!

First thing: THANKS for the plugin!
Second: I am sure, you do your best to make this plugin the best.
Third: I understand, that you re-wrote the plugin with a new, and better idea.

Of course, we all, who have already used it would like to convert to the new version... the easiest way.
And, I am sure, you do your best, again, to assist all of us with this transition.

May I ask you to describe again how to convert... in a way, that even me can understand it. (My knowledge of php, and thses things is very limited!)

Again: THANKS and greetings

Hi again!

I went trhough the changes... nad it WORKS now!!!
Great!
Thanks!

When re-modifying the Tags, Categories and Link Categories... the olda values are displayed... just I had to remove the "bla-bla" before and after the correct text.
It tooks some time, true, however, I think, I can invest this time... I am sure Quian Qin ahs put into it much more time and effort.

Thanks Q!

Greetings and Happy Xmas and New Year!

How to translate widget titles with qT2.0?
Look at http://isotype.org/it/ output

[Qian Qin]

in wp-includes/taxonomy.php function wp_get_object_terms()
[/code]

you should report that to the WP developers so they can start include missing filters.
I added a workaround which doesn't work as perfectly but doesn't need changes on WP side to the latest development version.

i'm working on the widget title issue...

Help! I just upgraded to qTranslate 2.0 and followed Q's steps, converting database, etc. However, when i try to toggle between languages on the website, I receive a "404 - no URL found" error. Did I do something wrong? Please help! Thanks!
