How to translate WordPress plugin into any language?

Question

I completed my plugin, now I want to provide multilingual functions for my users. I studied this, but it is difficult to implement.

I saw the translation of WordPress, but you need the basic steps to follow and translate my plugin.

I did it

1. loaded POEdit.
2. created the file "french.po" in the plugin
3. performed 'french.po' → 'french.mo'

Need to do

1. How to determine the MSGID in the output of a ro file?
2. How to load a po / mo file in a plugin?
3. How to replace shortcuts / text through po / mo file?
4. how to use __e() & ___() to replace "msgstr" on plugin pages?

Answer 1

With the Codestyling Localization plugin connected , you do not need to use POEdit.

I will show you an example of using 'localizationsample' as a text domain. In this case, the language files are located in the / lang / directory. They do not have to be these names in your real plugin; these are just examples.

Steps

• Add these lines to the comment header of the plugin that will be recognized by Codestyling Localization.

  Text domain: localizationsample
  Domain Path: / lang

• Create a directory called lang in your plugins directory.

• Install and activate the Codestyling Localization plugin.

• Go to Tools Localization

• Find your plugin and click Add New Language

• Select the language (country) to localize in the switch and click Create po-file . At this point, make sure the .po file is created in the lang folder.

• Click Rescan → scan now This is recommended because on my system, without doing this, the plugin always shows an error saying that "not all elements use the same text domain."

• Click Edit This will result in messages available for translation on another page. These messages are passed to the __() and _e() functions in the plugin code.

• Click Edit in the table next to Copy , then you will get a dialog box for entering a translation for each message. Complete the translation.

• Click generate mo-file . At this point, you should see the .mo file created in the lang folder.

• Change your language specified in wp-config.php to reflect the translation. The default is define('WPLANG', '');

Plugin example

 /* Plugin Name: Sample Localization Description: Demonstrates how to localize your plugin. Text Domain: localizationsample Domain Path: /lang */ // Localization add_action('init', 'localizationsample_init'); function localizationsample_init() { $path = dirname(plugin_basename( __FILE__ )) . '/lang/'; $loaded = load_plugin_textdomain( 'localizationsample', false, $path); if ($_GET['page'] == basename(__FILE__) && !$loaded) { echo '<div class="error">Sample Localization: ' . __('Could not load the localization file: ' . $path, 'localizationsample') . '</div>'; return; } } // Add Admin Menu add_action('admin_menu','localizationsample_menu'); function localizationsample_menu() { add_options_page( 'Localization Demo', // admin page title 'Localization Demo', // menu item name 'manage_options', // access privilege basename(__FILE__), // page slug for the option page 'localization_demo_adminpanel' // call-back function name ); } function localization_demo_adminpanel() { echo '<div class="wrap"><div id="icon-themes" class="icon32"></div>'; echo '<h2>' . __('Hi there!', 'localizationsample') . '</h2>'; echo '<p>'; _e('Hello world!', 'localizationsample'); echo '</p>'; echo '</div>'; // end of wrap }

(THIS EXAMPLE IS A TRANSLATION WHICH YOU CAN CHANGE TRADITIONS FOR YOUR ART.)

Each plugin chapter has a unique name. (eg:

 /* Plugin Name: my-pluginname ....... */ 

then in the plugin folder create the “Languages” folder;

then, in your plugin's .php file (somewhere on top), paste the initialization code:

 class load_language { public function __construct() { add_action('init', array($this, 'load_my_transl')); } public function load_my_transl() { load_plugin_textdomain('my-pluginname', FALSE, dirname(plugin_basename(__FILE__)).'/languages/'); } } $zzzz = new load_language; 

then open any text editor, then paste like this code (NOTE: The fact that we add only two examples of messages, "hello" and "bye", so that you can ADD AS MANY messages as YOU WANT with similar lines).

 # English translations for PACKAGE package. # Copyright (C) 2012 THE PACKAGE COPYRIGHT HOLDER # This file is distributed under the same license as the PACKAGE package. # Automatically generated, 2012. # msgid "" msgstr "" "Project-Id-Version: my-pluginname 1.0\n" "Report-Msgid-Bugs-To: \n" "POT-Creation-Date: 2012-08-06 13:46-0400\n" "PO-Revision-Date: 2013-03-21 11:20+0400\n" "Last-Translator: Automatically generated\n" "Language-Team: none\n" "MIME-Version: 1.0\n" "Content-Type: text/plain; charset=utf-8\n" "X-Poedit-SourceCharset: iso-8859-1\n" "Content-Transfer-Encoding: 8bit\n" "Plural-Forms: nplurals=2; plural=(n != 1);\n" "X-Generator: Poedit 1.5.4\n" #: mypluginindex.php:87 (it is just a line of a note, to remind where our code appears) msgid "mymessage1" msgstr "Hello" #: mypluginindex.php:88 msgid "mymessage2" msgstr "Bye" 

then save this file as "my-pluginname-en_US.po" (note that .po is a file extension, so make sure your text editor program has not been saved to "my-pluginname-en_US.po.TXT").

then download the POEDIT software and open this file. then edit the "translation" field and then save it as "my-pluginname -de_DE", two files will be created (if poEdit does not create a second file .mo automatically, just go to "File" → "Settings" → "Editor" and install checkbox "Automatically compile .mo file when saving"),

then put these two files in the Languages ​​folder.

after that open wp-config.php and find this code:

 define ('WPLANG, ''); 

and change to

 define ('WPLANG, 'de_DE'); 

it's all. when wordperss loads, it will read your plugin language file with the -de_DE prefix.

therefore, in the plugin file.php instead:

 echo "Something string"; 

you should use:

 echo __("mymessage1", 'my-pluginname'); 

Finished. Now you should check your plugin.
