i try your code but that doesn't work

Dbranes comments:

this works for me:

if(class_exists('MyPlugin')){
new MyPlugin();
}

class MyPlugin {
function __construct(){
add_action('plugins_loaded', array(&$this,'i18n'));
add_filter('the_content', array(&$this,'test_translation'));
}
function i18n() {
load_plugin_textdomain( 'myplugindomain', false, dirname( plugin_basename( __FILE__ ) ) . '/languages/');
}
function test_translation($content) {
return $content."<br/>test my translation:".__('Some translated string','myplugindomain');
}

} // end class


and in the wp_config.php file I select the language to use:

define('WPLANG', 'fr_FR');


and in the subfolder "/wp-content/plugins/myplugin/languages/" I have the files "myplugindomain-fr_FR.mo" and "myplugindomain-fr_FR.po".

at the top of my plugin i use your code like this :
if(class_exists('MyPlugin')){
new MyPlugin();
}
class MyPlugin {
function __construct(){
add_action('plugins_loaded', array(&$this,'i18n'));
add_filter('the_content', array(&$this,'test_translation'));
}
function i18n() {
load_plugin_textdomain( 'wpduplicateblog', false, dirname( plugin_basename( __FILE__ ) ) . '/');
}
function test_translation($content) {
return $content."<br/><br/><br/><br/><br/><br/>test my translation:".__('Create a clone','wpduplicateblog');
}
} // end class
in the admin no result. I don't see the sentence ($content)

i use wp multisite, is it important ?

Dbranes comments:

Maybe you could test this demo plugin code:

Create this folder

/wp-content/plugins/translationtest/


with the file "translationtest.php" with this code

<?php
/*
Plugin Name: Translation Test
Description: Translation Test plugin
Author: Dbranes
Version: 1.0
Text Domain: wpduplicateblog
*/

if(class_exists('TranslationTest')){
new TranslationTest();
}

if(!class_exists('TranslationTest')){
class TranslationTest {
function __construct(){
add_action('plugins_loaded', array(&$this,'i18n'));
add_filter('the_content', array(&$this,'test_translation'));
}
function i18n() {
load_plugin_textdomain( 'wpduplicateblog', false, dirname( plugin_basename( __FILE__ ) ) . '/');
}
function test_translation($content) {
return $content."<br/>test my translation:".__('Create a clone','wpduplicateblog');
}
} // end class
}


where your files wpduplicateblog-fr_FR.mo and wpduplicateblog-fr_FR.po are inside "/wp-content/plugins/translationtest/".

I have tested this on a multisite (both on where the plugin is activated for the whole network and activated per site) and it works.

(I see the translated text after each content post)

Maybe you can send me your language files to test?

cheers

Dbranes comments:

ps: just for the reference to guide others in similar problems, this seems to work on multisite

add_action('init','my_i18n');
function my_i18n(){
load_plugin_textdomain( 'wpduplicateblog', false, dirname( plugin_basename( __FILE__ ) ) . '/');
}


The debug version to check if the .mo file is found and loaded:

add_action('init','my_i18n_debug');
function my_i18n_debug(){

$loaded=load_plugin_textdomain( 'wpduplicateblog', false, dirname( plugin_basename( __FILE__ ) ) . '/');

if ( ! $loaded ){
echo "<hr/>";
echo "Error: the mo file was not found! ";
exit();
}else{
echo "<hr/><strong>Debug info</strong>:<br/>";
echo "WPLANG: ". WPLANG;
echo "<br/>";
echo "translate test: ". __('Some text','wpduplicateblog');
exit();
}
}


where 'wpduplicateblog' is the text-domain for the plugin and the .mo files are stored in the same folder in this case.


best regards
