【问题描述】：

我保存了这样的语言 cookie：

function aws_set_language_cookie() {

    //To save the language in a cookie
    
    $current_language = get_locale();
    
    if ($current_language == "es_ES") {
        $result = setcookie('lang', $current_language, time() + (30 * DAY_IN_SECONDS), '/');


    } else {
        $result = setcookie('lang', $current_language, time() + (30 * DAY_IN_SECONDS), '/');
    }

    //To read the cookie and change the language based on the cookie
    
    if (isset($_COOKIE['lang']) && $_COOKIE['lang'] == "es_ES") {
        //need code to change website language to spanish here
    }
}

如何在最后一个 if 语句中将语言更改为西班牙语？

【解决方案1】：

 /* you have not mention that your code written with which hook but there is one hook available to change language run time in wordpress */ 
/* please try you code with below hook function */

add_filter('locale', 'set_my_locale');

    function set_my_locale( $lang ) { 
        if ( isset($_COOKIE['lang']) && $_COOKIE['lang'] == "es_ES") {   
            return 'es_ES'; 
        } else { 
           // return original language 
       }
     }
