我创建一个插件只是为了测试

/**
 * @package SurveyPlugin
 * @version 1.0
 */
/*
Plugin Name: Survey Plugin
Plugin URI: http:marcogomesweb.com
Description: This is survey
Author: NodeLondon
Version: 1.0
License: GPLv2 or later
Text Domain: survey-plugin
*/

function get_dummy_text() {
    $text = [
        __( \'city hotels\' , \'survey-plugin\' )
    ];
    return $text[0];
}

add_action(\'admin_notices\', \'show_dummy_text\');

function show_dummy_text(){
    $text = get_dummy_text();
    global $locale;
    echo "<br>". $locale . "<br>";
    echo "<p id=\'wp-admin-motivation\'>$text</p>";
}


add_action( \'plugins_loaded\', \'wan_loaded_textdomain\');


function wan_loaded_textdomain(){

     $loadfiles = load_plugin_textdomain(\'survey-plugin\', false, 
     dirname( plugin_basename( __FILE__ ) ) . \'/languages/\' );

     plugin_basename( __FILE__ ). \'/languages/\' );



     var_dump($loadfiles); // is always false


}

我安装Poedit，我创建一个。mo文件survey-plugi-es_ES.mo在里面/plugins/survey-plugin/languages/

#: survey-plugin.php:79
msgid "city hotels"
msgstr "ciudad"

这就是回声

更改中的语言后settings / site languages仍然显示相同，

我在跟踪这个tutorial 但还是不知道为什么

load_plugin_textdomain( \'survey-plugin\', false, dirname( plugin_basename( __FILE__ ) ) . \'/languages/\' )
