Yii Module to handle translations

This extension collects all untranslated messages in the page and then you can add a button to translate, translate automatically using google translate, check for missing translations, edit translations and more.

Basic usage:

echo Yii::t('app','Some text').' - '.Yii::t('app','some other text');
Yii::app()->translate->editLink('Translate');

Setup

In your config :

<?php
return array(
    'preload'=>array('translate'),//either here or somewhere in the beginning
    //set up and import the module
    'modules'=>array(
        'translate'
    ),
    'import'=>array(
        'application.modules.translate.TranslateModule'
    ),
    'components'=>array(
        //define the class and its missingTranslation event
        'messages'=>array(
            'class'=>'CDbMessageSource',
            'onMissingTranslation' => array('TranslateModule', 'missingTranslation'),
        ),
        'translate'=>array(//if you name your component something else change TranslateModule
            'class'=>'translate.components.MPTranslate',
            //any avaliable options here
            'acceptedLanguages'=>array(
                  'en'=>'English',
                  'pt'=>'Portugues',
                  'es'=>'Español'
            ),
        ),
    )
);

Do not forget to create the tables like described here

the id of message source must be auto-incremental

the name of the tables can be modified

CREATE TABLE SourceMessage
(
    id INTEGER PRIMARY KEY AUTO_INCREMENT,
    category VARCHAR(32),
    message TEXT
);
CREATE TABLE Message
(
    id INTEGER,
    language VARCHAR(16),
    translation TEXT,
    PRIMARY KEY (id, language),
    CONSTRAINT FK_Message_SourceMessage FOREIGN KEY (id)
         REFERENCES SourceMessage (id) ON DELETE CASCADE ON UPDATE RESTRICT
);

How to use

somewhere in your application define the language like the following:

//shortcut
$translate=Yii::app()->translate;
//in your layout add
echo $translate->dropdown();
//adn this
if($translate->hasMessages()){
  //generates a to the page where you translate the missing translations found in this page
  echo $translate->translateLink('Translate');
  //or a dialog
  echo $translate->translateDialogLink('Translate','Translate page title');
}
//link to the page where you edit the translations
echo $translate->editLink('Edit translations page');
