我搜索了很多资源之后就知道了:
function lang_support() {
return array('en','fr'); // Add your support lang-code (1st place is a default)
}
function rewrite_lang(){
$langs = lang_support();
foreach($langs as $lang) {
add_rewrite_endpoint($lang,EP_PERMALINK|EP_PAGES|EP_ROOT|EP_CATEGORIES);
}
}
add_action('init','rewrite_lang');
function lang(){
global $wp_query;
$langs = lang_support();
$lang_r = "";
foreach($langs as $lang) {
if(isset($wp_query->query_vars[$lang])) {
$lang_r = $lang;
$_SESSION['lang'] = $lang_r;
}
}
if(in_array($lang_r,$langs)) {
return $lang_r;
} else {
return $langs[0];
}
}
function init_session(){session_start();}
add_action('init','init_session',1);
function lang_session() { // Redirect by JS if session is set
$url_lang= basename($_SERVER['REQUEST_URI']);
if(!in_array($url_lang,lang_support()) && isset($_SESSION['lang'])) {
if(!is_404()) {
wp_redirect(currentURL().$_SESSION['lang'],301);
exit;
}
}
}
add_action('wp_head','lang_session');
function output_buffer() {ob_start();}
add_action('init','output_buffer');
function currentURL() {
$pageURL=(@$_SERVER["HTTPS"]=="on")?"https://":"http://";
if($_SERVER["SERVER_PORT"]!="80"){
$pageURL.=$_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
}else{
$pageURL.=$_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
将此代码添加到中functions.php
。添加代码后,转到wp-admin/options-permalink.php
并按Save Changes
因此,现在您可以像在模板中那样检查/使用语言代码。
<?php echo lang();?>
要么
if( lang() === "en" )
使用我的示例代码的示例工作网址:
http://domain.com/ <-- "en"
http://domain.com/en/ <-- "en"
http://domain.com/fr/ <-- "fr"
http://domain.com/es/ <-- "en" (coz , "es" code not set)
http://domain.com/mypage/ <-- "en" (work with "page")
http://domain.com/mypage/fr/ <-- "fr"
http://domain.com/mypage/es/ <-- "en" (coz , "es" code not set)
http://domain.com/mypost/ <-- "en" (work with "post")
http://domain.com/mypost/fr/ <-- "fr"
http://domain.com/mypost/es/ <-- "en" (coz , "es" code not set)
