Translating Question2Answer into another language

Question2Answer fully supports non-English languages and is easy to translate. Before proceeding, it's worth checking here to see if a translation is already available. You may be able to use this immediately, or only have to add some missing phrases.

Creating a new translation

To create a new Question2Answer translation from scratch, follow the steps below:

Open the file qa-app-admin.php inside Question2Answer's qa-include directory and look at the function qa_admin_language_options(). This contains an array which maps abbreviated language codes to their corresponding languages. For example, the abbreviation for Russian is ru. Note down the abbreviation for your language. If your language is not in the array, you may add it, but please also tell us so we can include it in future versions.
Create a subdirectory inside Question2Answer's qa-lang directory, and name the subdirectory with the abbreviation for your language, keeping the original capitalization.
Copy (don't move!) all of the qa-lang-*.php files in Question2Answer's qa-include directory to the new language directory you created. This is currently a total of 8 files.
Log in to your Question2Answer site as an administrator, open the Admin panel, select your language, and click to save.
Now you can translate each of the copied qa-lang-*.php files that you created. To translate each file:
- Open the file in a text editor using UTF-8 encoding and ensure you do not add a BOM (byte order mark).
- In each line of the file, translate the phrase after the => symbol to your language.
- Pay attention to substitution points, which use the hat symbol (^). These can be moved but not removed. In some cases, the ^ symbol is followed by a number or word, such as ^1 or ^site_title, and this should also be preserved.
- If you are not sure how a phrase is used, you may search for its key in the Question2Answer source code. The key is the string in quotes before => on each line.
- To leave a particular phrase in US English, you may remove its line from the file. You may also choose to remove the files qa-lang-admin.php and qa-lang-options.php - these are only used for the admin interface and do not contain any phrases which are visible to normal users of Q2A.
As you proceed with the translation, you can check your work by saving the qa-lang-*.php file you are working on, then viewing or refreshing the appropriate pages in your browser.
qa-check-lang.php is your friend! As you work, use your web browser to view the qa-include/qa-check-lang.php page within your Question2Answer site. This will check your language files for any omitted phrases or substitutions.
Please consider sending us your translation or making it available online, so that we can link to it here.

Updating an existing translation

An incomplete Question2Answer translation may be available for your language, for example because it has not been updated for the latest version of Q2A. To update a translation for the version you are running, follow the steps below:

Download and install the language by placing its directory (such as fr or ru) in Q2A's qa-lang directory.
Log in to your Question2Answer site as an administrator, open the Admin panel, select your language, and click to save.
qa-check-lang.php is your best friend! Use your web browser to view the qa-include/qa-check-lang.php page within your Question2Answer site. This will check your language files for errors and auto-generate the PHP code for missing phrases.
For each qa-lang-*.php file that needs attention:
- Open the file in a text editor using UTF-8 encoding and ensure you do not add a BOM (byte order mark).
- Copy and paste the appropriate PHP code from qa-include/qa-check-lang.php into the middle of this file.
- For each line that you pasted, translate the phrase after the => symbol to your language.
- Pay attention to substitution points, which use the hat symbol (^). These can be moved but not removed.
As you work, refresh qa-include/qa-check-lang.php in your web browser and ensure that you resolve all issues shown. You can also browse around your Q2A site to see how the translated phrases are used in context.

Customizing selected URLs or phrases

From version 1.4, it is possible to modify some of the URLs used within a Q2A site. For example, http://mysite.com/questions could be replaced with http://mysite.com/proposals. To do this, look for the commented $QA_CONST_PATH_MAP definition in qa-config.php. This shows an example of how to define a PHP array which modifies the standard URLs used.

Starting in version 1.5, it is also possible to customize specific language phrases for your Q2A site without installing a full translation. To customize a particular phrase, follow the steps below:

Search the qa-include/qa-lang-*.php files to find the file and line containing the phrase.
Create a qa-lang-*.php file in Q2A's qa-lang/custom directory, with the same name as the file that you found in the previous step, and paste in the following code:
```
<?php

	return array(
		// custom phrases go here...
	);
```
Copy the line containing your phrase from Q2A's qa-lang-*.php file into the middle of the array( ) in your new file.
Change the text that comes after the => symbol to suit your requirements. Pay attention to substitution points, which use the hat symbol (^). For non-English languages, ensure your text editor is using UTF-8 encoding without a BOM (byte order mark).

Below is an example qa-lang/custom/qa-lang-main.php file which modifies the 'Hello [username]' and 'My Account' phrases:

<?php

	return array(
		'logged_in_x' => 'Welcome, ^!',
		'nav_account' => 'My Settings',
	);
