Translating Strings

[parkerj]

I am using the following function to translate strings in an application I created. However, I am not sure if I am using it correctly because the strings are not translating. Below is my function:

function _t($msgid)
{
    $t = new Gettext\Translator();

    $t->loadTranslations(APP_PATH . 'lang' . DS . 'it_IT.php');

    $t->register();

    return __($msgid);
}

I exported the .po file into php arrays. But for some reason, the strings are not being translated into Italian. Am I instantiating the class incorrectly or missing a step?

The translator instance must be created and register just once. It loads all translations, so you don't need the _t function.

$t = new Gettext\Translator();
$t->loadTranslations(APP_PATH . 'lang' . DS . 'it_IT.php');

echo $t->gettext($msgid);

//register to use global functions: __(), n__(), etc...
$t->register();

echo __($msid);

//or if you preffer the _t() function:
function _t($msgid) {
    return __($msgid);
}

If, however, the strings still being untranslated, maybe they're not included in the array stored in it_IT.php.

Ok, got it. Now, if it can only be registered once, how can I emulate native gettext to utilize more than one domain:

default-it_IT.php
plugin-it_IT.php

Previously, my function was:

function _t($msgid, $domain = '')
{
    if ($domain !== '') {
        return dgettext($domain, $msgid);
    } else {
        return gettext($msgid);
    }
}

For the default domain, the $domain variable was null, but if I have a plugin with it's own language directory, then the $domain variable would not be null. The reason I don't want to use native gettext, is because I want the freedom to define the locales instead of having to be chained to /en_US/LC_MESSAGES/ and so forth.

From reading the docs and the code, it seems as though multi-domains without using native gettext could be possible. How, could I accomplish this with only having to $register global functions only once?

Thanks for your help.

You can see the TranslatorInterface to know all available functions to get translations (https://github.com/oscarotero/Gettext/blob/master/src/TranslatorInterface.php). All these methods are available also in the global functions (https://github.com/oscarotero/Gettext/blob/master/src/translator_functions.php)

$t = new Gettext\Translator();
$t->loadTranslations(APP_PATH . 'lang' . DS . 'default-it_IT.php');
$t->loadTranslations(APP_PATH . 'lang' . DS . 'plugin-it_IT.php');

//Get translation using the default domain (messages)
$t->gettext('hello');

//Get translation using other domain
$t->dgettext('plugin-domain', 'hello');

//Singular-plural translations
$t->ngettext('one comment', 'various comments', $numComments);

//Domain + Singular-plural translations
$t->dngettext('plugin-domain', 'one comment', 'various comments', $numComments);

//etc... To use as global functions:
$t->register();

echo __('hello');
echo d__('plugin-domain', 'hello');
//etc

Thanks. I am still having some issue with strings translating. I am using your first suggestion without trying to implement multi-domains yet. When using the .php array file, nothing happens (yes the translated strings are in the array). When I instead use the .po file, it echoes the content of the file instead of translating the strings. Have any ideas of what I could be doing to cause such anomalies? Attached is a screenshot.

This first bit of code below, whether I use .php or .po returns nothing. The second bit of code, is what the screenshot produces when using .po and returns nothing when using .php.

$t = new \app\src\Gettext\Translator();
$translations = \app\src\Gettext\Translations::fromPoFile($path . $domain . '-' . $locale . '.php');
$t->loadTranslations($translations);

$t = new \app\src\Gettext\Translator();
$t->loadTranslations($path . $domain . '-' . $locale . '.po');

The Translator does not load .po files directly, only load php arrays (internally it does a include, so this is why you can see the content of the file).
How was created the php array? It must be created using the phpArray generator. For example:

use Gettext\Translations;
use Gettext\Translator;

//load a .po file
$translations = Translations::fromPoFile('translations.po');

//generate a php array file
$translations->toPhpArrayFile('translations.php');

//Create a translator
$t = new Translator();

//Load the php with the translations
$t->loadTranslations('translations.php');

//use it
$t->gettext('msgid');

Ok, I will try generating it again, and then let you know.

All set. Thanks again for your help.
