WIDGETS

to enrich widget enable themes

Theme

Languages list

Display the list of available languages

Multiple widgets possible. If your theme contains functions that offer widget personalization, the item type must be filled. (see this post)

sidebar

Recent comments

Display the list of recent comments in current displayed language.

This widget was created because the default one cannot be translatable or offer sub-selection in one language.

multiple widgets possible

sidebar

Recent posts

Display list of recent posts in a choosen language

since v 1.4.0 for WP >2.8

This new widget solves conflicts or issues occuring when WP default widget is present (contains an obscur `wp_reset_query`). Also a choice of language of this list of recent posts is possible – not necessary the same of the current page. And you can install multiple widgets. Replace WP Recent Widget by this one named – List of recent posts –

multiple widgets possible with different languages (fixed or dynamic)

 ----xili-language widgets: the new "multiple" widget to display list of recent posts in a choosen language.

sidebar

TEMPLATE TAGS

usable by theme’s designer and webmaster

Theme

xiliml_the_other_posts
default parameters:
($post_ID,$before = « This post in », $separator = « , « , $type = « display »)

in loop display the link of other posts defined as in other languages

can be used in theme template in single.php under the title

* example: if(class_exists(‘xili_language’)) xiliml_the_other_posts($post->ID)

(in the example, the default template tag was hooked to display flag – see hooks rows below)

post – page – loop

xili_post_language
default parameters:
($before = ‘<span class= »xili-lang »>(‘, $after =’)</span>’)

in loop display the language of the post

Useful inside a multilingual category loop.

 
<div class="postsubtitleinfo">
	<small><?php 
			the_time(); /*__('F jS, Y','xilidev')*/
			echo "&nbsp;-&nbsp;";
			if (class_exists('xili_language')) xili_post_language(); ?></small></div>

loop, category, search

xili_language_list
default parameters:
($before = ‘<li>’, $after ='</li>’, $theoption= »)

outside loop (sidebar) display the languages of the site (used also by widget)

When the theme don’t enable widget. Use this template tag to display the list in sidebar or (header and footer)

 
<h2><?php _e('Languages','xilidev') ?></h2>
	<ul class="langs">
		<?php if (function_exists('xili_language_list')) {
			xili_language_list('<li>','</li>','siderss');
		} ?>
	</ul>

sidebar

xiliml_the_category
default parameters:
($post_ID, $separator = ‘, ‘ ,$echo = true)

replace the_category() tag of WP Core

The current template tag the_category is not hookable by plugin. So here the categories list of a post inside loop will be translated according the language of the current post.

 

<p class="postmetadata"><?php the_tags(__('Tags: ','xiliips'), ', ', '<br />'); echo " "; _e('Posted in','xiliips'); echo " "; 
				if (class_exists('xili_language')) {
					xiliml_the_category(get_the_ID(),', ');
				} else {
					the_category(', ');
				}  ?> | <?php edit_post_link(__('Edit','xiliips'), '', ' | '); ?>  <?php comments_popup_link(__('No Comments &#187;','xiliips'), __('1 Comment &#187;','xiliips'), __('% Comments &#187;','xiliips')); ?></p>

post – page – loop

xiliml_langinsearchform
default parameters:
($before= »,$after= »)

Template Tag insertable in search form for sub-selection of a language

As in example, this function add a way to limit the search to a target language.

 

<h2><?php _e('Search','xilidev') ?></h2>
              <form id="searchform" method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>">
 
                <input type="text" name="s" id="s" size="15" value="<?php the_search_query(); ?>" />
 
                <input type="submit" value="<?php _e('go','xilidev'); ?>" /><br/>
                <?php if(function_exists('xiliml_langinsearchform')) xiliml_langinsearchform ('<span class="radiosearch" >','</span>') ?>
 
              </form>

search – sidebar

sidebar

function xiliml_force_loop_lang ($lang_query_tag)

functions to change loop’s query tag of language

useful for sidebar widgets and latest posts widget – since 1.3.0

Even if the main loop is in one language, in the sidebar, it is possible to « force » the language in another one for the widgets.

 
<?php 
xiliml_force_loop_lang("fr_fr");
if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('Sidebar top')) : ?>
<ul>
 <li>?</li>
</ul>
<?php  endif; xiliml_restore_loop_lang(); ?>
			<?php 
					xiliml_force_loop_lang("en_us");
					if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('Sidebar topus')) : ?>
 
			<ul>
 				<li>?</li>
			</ul>
			<?php  endif; xiliml_restore_loop_lang(); ?>

Another example :

<?php 
 //echo the_curlang();
 /* in this case, the widgets are forced as current lang of the theme - useful in home when query tag 'lang' is not defined -*/
 xiliml_force_loop_lang(the_curlang());
  if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('Sidebar top')) : ?>
 <ul>
  <li>?</li>
 </ul>
 <?php  endif; xiliml_restore_loop_lang(); ?>

In this example described formerly, the list of languages is enriched by flags:

function my_xili_language_list($before = '<li>', $after ='</li>',$theoption) {
global $wp_query;
	if ($theoption == 'top') { /* usable in type item in new multiple widget */
		$listlanguages = get_terms_of_groups_lite (the_cur_langs_group_id(),TAXOLANGSGROUP,TAXONAME,'ASC');
		$a ='';
		$currenturl = get_bloginfo('siteurl').'/?';
		foreach ($listlanguages as $language) { //QUETAG
			if ($language->slug != 'ar_ar' && $language->slug != 'ar_ma') {
				$a .= $before ."<a href='".$currenturl."hlang"."=".$language->slug."' title='".__('Latest posts selected',THEME_TEXTDOMAIN)." ".__('in '.$language->description,THEME_TEXTDOMAIN)."'>"." <img src='".get_bloginfo('template_directory')."/images/flags/".$language->slug.".png' alt='' /></a>".$after;
			}
		}
		echo $a;
	} else { /* the current list in sidebar with category sub selection*/
		if (is_category()) {  
			$catcur = xiliml_get_category_link();

				if ($before=='<li>') {
					if (the_curlang() == $language->slug) { 
						$beforee = '<li class="current-cat" >';
					} else {
						$beforee ='<li>';
					}
				}
				 $a .= $beforee ."<a href='".$currenturl.QUETAG."=".$language->slug."' title='".__('Posts selected',THEME_TEXTDOMAIN)." ".__('in '.$language->description,THEME_TEXTDOMAIN)."'>"." <img src='".get_bloginfo('template_directory')."/images/flags/".$language->slug.".png' alt='' /> ". __('in '.$language->description,THEME_TEXTDOMAIN) ."</a>".$after;
			}
 
		}
		if (is_category()) {
			$currenturl = xiliml_get_category_link();

OTHER FILTERS

Some template tags inside WP core are not fully multilingual and need filters.

the_time

add_filter(‘the_time’,’my_date’,10,2);

 Date management and translation are very complicated. Here by using a xili-language function, it is possible to modify the basic behaviour of the current template tag the_time. 
function my_date($thetime,$theformat) {
  /* param no used because php format */	
  return the_xili_local_time('%B %d, %Y - %H:%M',strtotime(get_the_time('m/d/Y H:i')));
}
add_filter('the_time','my_date',10,2);
 Post, Page

the_modified_time

add_filter(‘the_modified_time’,’my_modified_date’,10,2);

 Date management and translation are very complicated. Here by using a xili-language function, it is possible to modify the basic behaviour of the current template tag the_modified_time. 
function my_modified_date($thetime,$theformat) {
  /* param no used because php format */	
  return the_xili_local_time('%B %d, %Y - %H:%M',strtotime(get_the_modified_time('m/d/Y H:i')));
}
add_filter('the_modified_time','my_modified_date',10,2);
 Post, Page

get_comment_date

add_filter(‘get_comment_date’,’my_comment_date’,10,2);

 This is the date of each comments in the comments loop. 
function my_comment_date($comment_time,$d = '') {
  /* params no used because php format */
  /* the first param is to be as msgid in .po example: %B %d, %Y - %H:%M or %B %d, %Y at %H:%M   */	
  return the_xili_local_time('%B %d, %Y', strtotime(get_comment_time ('m/d/Y H:i'))); 
  /* impossible to use get_comment_date as it is itself filtered*/
}
add_filter('get_comment_date','my_comment_date',10,2);
