我想改进一个 Wordpress 插件,它结合 WPML 向菜单添加一个或多个标志。(插件名称:菜单中的 WPML 标志)它应该只适用于主要位置的菜单,而不适用于侧边栏或页脚等其他位置。
<?php
/*
Plugin Name: WPML flag in menu
Plugin URI: http://www.MijnPress.nl
Description: Shows translated flags (for every language except current viewing lang) in the default or wp_nav_menu at last position
Version: 1.1
Author: Ramon Fincken
Author URI: http://www.MijnPress.nl
*/
add_filter( 'wp_nav_menu_items', 'plugin_wpml_flag_in_menu' );
function plugin_wpml_flag_in_menu($items, $args = NULL)
{
if(function_exists('icl_get_languages'))
{
$languages = icl_get_languages('skip_missing=0&orderby=code');
$new_items = '';
if(!empty($languages)){
foreach($languages as $l){
// Exclude current viewing language
if($l['language_code'] != ICL_LANGUAGE_CODE)
{
$new_items .= '<li class="menu-item menu-item-type-post_type menu-item-object-page">';
if(!$l['active']) $new_items .= '<a href="'.$l['url'].'">';
if($l['country_flag_url']){
$new_items .= '<img src="'.$l['country_flag_url'].'" height="12" alt="'.$l['language_code'].'" width="18" />';
}
// $items .= icl_disp_language($l['native_name'], $l['translated_name']);
if(!$l['active']) $new_items .= '</a>';
$new_items .= '</li>';
}
}
}
}
// Idea by Simon Weil
if(is_rtl())
{
$items = $new_items.$items;
}
else
{
$items .= $new_items;
}
return $items;
}
?>
我想用“if(function_exists('icl_get_languages') && $location == 'primary')”之类的东西来扩展if语句(“if(function_exists('icl_get_languages'))”,但我不知道如何得到“当前位置”的值。
