Yii 1.1: translate

Module to handle translations

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');


In your config :

return array(
    'preload'=>array('translate'),//either here or somewhere in the beginning
    //set up and import the module
        //define the class and its missingTranslation event
            'onMissingTranslation' => array('TranslateModule', 'missingTranslation'),
        'translate'=>array(//if you name your component something else change TranslateModule
            //any avaliable options here

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
    category VARCHAR(32),
    message TEXT
    id INTEGER,
    language VARCHAR(16),
    translation TEXT,
    PRIMARY KEY (id, language),
    CONSTRAINT FK_Message_SourceMessage FOREIGN KEY (id)

How to use

Extract the file to protected/modules

somewhere in your application define the language like the following:

//in your layout add
echo $translate->dropdown();
//adn this
  //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');
//link to the page where you check for all unstranslated messages of the system
echo $translate->missingLink('Missing translations page');

Options avaliable

string $defaultLanguage

array $dialogOptions

string $googleApiKey

Methods avaliable

for the translate components use it like this:


string getLanguage()

Returns the language in use. The language is determined by many variables: session, post, get, header in this order. It will filter the language by using accepted languages. If is set "en_US" and it is not avaliable, then it will check if "en" is avaliable.

string setLanguage($language=null)

If $language is null then it will use getLanguage to determine it. It doesn't check if the language is in the accepted languages. Returns the language setted.

boolean hasMessage()

Return wheter there are messages to be translated in this page

string dropdown()

array getGoogleAcceptedLanguages($targetLanguage=null)

returns an array containing all languages accepted by google translate. Option googleApiKey must be defined to use this service.

string translateLink($label,$type='link')

string translateDialogLink($label,$title=null,$type='link')

Generates a link or button that generates a dialog to the page where you translate the missing translations found in this page.

string editLink($label,$type='link')

Creates a link to the page where you edit the translations.

string missingLink($label,$type='link')

if you are running php 5.3 you can use any method like this MPTranslate::someMethod($someArg);

bug in case insensitive words

4- I find a bug, the missingTranslation() function is not case insensitive, so if exist a record with name "By" and translated it, then if use Yii::t('main', 'by'); don't show translated "By" and also don't add record "by" for new translate!

1-It doesn't have this ability yet. Could you open a ticket in github page? As soon as I have time I'll implement it.

2-For none of those pages? It should have. It showed to me last time I check. I'll take a look around and get back to you

3-You are probably right! I actually didn't check this scenario but the logic is right. I usually use only in development and enable it in admin application

about slow

3- Note about your last paragraph that you said this module is slow, I against with this subject! Note that when exist missing translated word, execute one query for each Yii:t, and this is correct and was slow, But If you do translate all words in all language, so don't execute addition query and was fast.

how store all messages in database

Thanks for great module.

1- In here when visit a page, store all words(in current page) of Yii::t in database, but how can store all words of all .php files in database just by one click, be like yiic message messages/config.php command.

not able to translate all the components of the page

Is it possible to translate the whole page without using Yii::t on each content type ? I was hoping for something that works on the lines of me selecting a language and the whole page showing translated to the selected language.

redirect after switching language


First of all, thank you for this great extension :) In TranslateBaseController.php there's a redirect() method. From what I understood, this is called when the user selects a new language. I've got an iFrame in the page I'm using, and you may know, in some browsers an iFrame needs to be "manually" refreshed in order to reload with the right content. So I've put the following line of code, right after registerScript() call:

Yii::app()->getClientScript()->registerScript("reloadIframe","var frame=document.getElementById('teaser'); frame.src=frame.src;",CClientScript::POS_READY);

I know this code does the job to refresh the ifram, but it doesn't seem to be used at all in the page after the redirection. Am I missing anything?

Thanks for your help.

Hey tenebriox I didn't write unit tests for it, but it has been stable for some time now.

about load for some users only, yes I only load it on administrative application, but I guess you can check if user has access in onBeginRequest event (before the application dispatch the route) and add the module dinamically if he has


and define the component as usual

also check access before add links to translate pages

Cheers, Gustavo

Dynamically load this module

Hi, First of all thank you for this awesome work, very useful :)

You say this module will slow down your application, use it for development only. So, is it possible to load this module dynamically just for special users ?

It's not fully tested. I'm expecting your feedback to improve it Did you write unit tests ? Is it possible to get them ?

getPreferedLanguage false doesn't managed yet

Hi, I found an issue in your extension when i try to run W3C validator which doesn't include preferedlanguage in his http header request. In your components/MPTranslate, line 205, il your $language was retrieve using getPreferedLanguage (and if it returned false), you will throw a 500 error.

// l.205 where $language has to be a string

I fixed it adding a simple check.

            return $language;
        elseif(isset($_POST[$key]) && !empty($_POST[$key]))
        elseif(isset($_GET[$key]) && !empty($_GET[$key]))
//            $language=Yii::app()->getRequest()->getPreferredLanguage();
        else if (Yii::app()->getRequest()->getPreferredLanguage()!=false)

I hope it can help...

Thanks ! I'm happy that it was useful to you

I believe that the functionality you are looking for is in the "editLink" method that method will create a link to the page where you edit the translations

get keys and translations of a page (allready translated ones)

Hi gusnips great thanks for your extension it's really usefull I'm using translate as my main translation tool in my site

The list of missing translations is really usefull when I'm on a page. but now that I have done all the missing translations, it would be great to have all keys for editing at any time. it would work similarly as missing index but would list all the keys with the translations of the active language for the page we are on. is something like this maybe allready available ? hard to set up ? Thanks again

If using google change language code to work

with google 'en_us' is not working you have to change it to 'en'

in the config file:

'sourceLanguage'    =>'en',
