Without changing or adding specific template tags, the_time(), the_modified_time() and other functions are hookable by xili-language.

The « hooking » functions are placed inside the xilidev-libraries (see this post).

function xiliml_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','xiliml_comment_date',10,2);
 
 
function xiliml_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','xiliml_date',10,2);
 
function xiliml_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','xiliml_modified_date',10,2);

Basically WordPress uses php date() format – http://fr2.php.net/manual/en/function.date.php – and and internal static translation tools.

In the hooking function and in date format translation, the format depending of setlocale is used. See – http://fr2.php.net/manual/en/function.strftime.php –

With this way and if the server is well configured, the live translation of date / time works well.

For the .po file, the msgid format is ‘%B %d, %Y – %H:%M‘ and his translation in french can be ‘%d %B %Y – %Hh%M‘

FAQ

* Why are these hooks inside the xilidev library and not inside the plugin itself ?

Because the webmaster can modify it and the modifications will be not erased when the plugin is updated. (Don’t forget to check (and activate) this library in admin plugin’s UI)

xilidev or gold functions

Because they need big translation and lot of lines. So it was better to bypass it and insert more flexible properties.

* In the_time() how to suppress the time ?

Just modify the string ‘%B %d, %Y – %H:%M’ in ‘%B %d, %Y’ .

* What do the function the_xili_local_time() ?

This function inside the plugin translates a generic numeric date according current language of the post or the theme’s live language.

* On my website, I use different patterns inside the_time() depending category or single or… What do you recommend ?
Inside the filter function, add php ‘switch case‘ lines analyzing the $theformat passed (php format) and deliver – according these – the first param of the_xili_local_time() a setlocale format with %. It is indeed easy to choose a result with or without hour:min. After you have defined the list of format, don’t forget to translate them in .po (and .mo) of each language.

Gold functions

Gold functions

In sidebox « Settings », a new check button appears if a folder named xilidev-libraries and containing a functions.php file was present inside your wp/content/plugins/ folder.
If this button is checked, all the functions inside this file was added when plugin is activated. Why it is interesting ? When adding here special filters or actions for hookable template tags of xili-language, you don’t need to copy and paste your functions of one theme to another theme.

New functions in core of xili-language

Two new functions was added for developers (since February – 3 new for time display) :
xiliml_get_lang_object_of_post($post_ID) Return an object containing properties of the language set to the post passed as param (false if the post don’t exist or undefined language) See code for more infos.
xiliml_get_language($lang_nameorslug="") Return an object containing properties of the language passed as slug (ex fr_fr) or name (ex fr_FR). False if the language doesn’t exist. $result->description gives the full name of the language set by you in xili-language settings.

To illustrate these new features, please find an example of functions.php here containing only two functions to create a shortcode named linkpost.

<?php
/**
 * shortcode to insert link to post in other languages inside the content 
 * example : [linkpost lang="fr_FR"]link to french similar post[/linkpost] (if title="some text" : title of link is set by replacing title 'A similar post in...')
 *
 *
 *@since 1.2
 */
function xiliml_build_linked_posts_shortcode($atts,$content=null) {
	global $post;
	$arr_result = shortcode_atts(array('lang'=>'','title'=>''), $atts);
	extract($arr_result);
	$language = xiliml_get_language($lang); /* test if lang is available */
 
	if ($language !== false) {
		$otherpost = get_post_meta($post->ID, 'lang-'.$language->slug, true);
	}
 
	if ($otherpost) {
		if ('' == $title) {
			$obj_lang = xiliml_get_lang_object_of_post($otherpost);
			if (false !== $obj_lang) {
				$description = $obj_lang->description;
				$title = __('A similar post in',THEME_TEXTDOMAIN).' '.$description;
			} else {
				$title = __('Error with target post #',THEME_TEXTDOMAIN).$otherpost;
			}
		}
		$output = '<a href="'.get_permalink($otherpost).'" title="'.$title.'">'.$content.'</a>';
		/* this link above can be enriched by image or flag */
	} else {
		$output = '<a href="#" title="'.__('Error: other post not present !!!','xili-language').'">'.$content.'</a>';
	}
	return $output;
}
add_shortcode('linkpost', 'xiliml_build_linked_posts_shortcode');
 
?>

This table is a summary of the « technical » features of xili-language plugin and is dedicaced to webmaster and theme’s designer.

Toolbox: xili-language plugin for a multilingual website in one table
Name	Definition	Comment	Example	Concern
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)	----	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

get_cur_language ($post_ID)	Return the language of current post in loop		see below	loop
get_cur_post_lang_dir ($post_ID)	Return the lang and dir of language of current post in loop.	The example on right uses this tag and the above one.	while (have_posts()) : the_post(); $langdir = ((function_exists('get_cur_post_lang_dir')) ? get_cur_post_lang_dir($post->ID) : array()); ?> <div class="story <?php echo $langdir['direction'] ?> <?php echo 'borders_'.get_cur_language($post->ID); /*style*/ ?>">	loop

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);	Comments

[xilifloom frame_id="blinds-contv2"]

A short description of the frame (div containing frame and images)

the divs of the demo - blue borders

#blinds-cont { -webkit-box-shadow: 0 0 20px #000; background: url(bg.png) 0 0 no-repeat; margin: 20px auto; padding: 12px 0 0 0; font-family: 'Georgia', 'Arial Narrow', 'Arial', sans-serif; height: 254px; -moz-box-shadow: 0 0 20px #000; width: 620px; }
#blinds-cont #blinds { margin: 0 auto; background: url(spinner.gif) 50% no-repeat; height: 204px; width: 596px; }
#blinds-cont #blinds .floom_slice { z-index: 10; }
#blinds-cont #blinds .floom_caption { text-shadow: 0 1px 0 #fff; font-size: 1.0em; color: #333; font-style: italic; position: relative; text-align: center; width: 100%; top: 15px; }
#blinds-cont #blinds .floom_progressbar { font-size: 1px; background: #131718; border-bottom: solid 1px #fff; height: 3px; position: relative; z-index: 1000; width: 0; top: 2px; }
#blinds-cont #blinds .floom_container { overflow: hidden; border-bottom: solid 1px #fff; border-top: solid 1px #666; }
#blinds-cont #blinds .floom_vertical { float: left; }

In this horizontal demo case, the frame contains a shadowed border (visible in Safari or Mozilla) and a background frame image with a large bottom part for title of image.

Which are the characteristics here?

The ID (#) « blinds-contv2″ is set (and used in shortcode). the image (#blinds) div has height and width equal to size of series of images. The container (frame) is a little bigger to create a border especially on bottom for description.
Here before to create a new one, the frame don’t use image as background. It is only black.
The resulting second part of the floom.css is:

#blinds-contv2 { -webkit-box-shadow: 0 0 10px #000; background: #000; margin: 20px 30x 20px; padding: 10px 0 0 0; font-family: 'Georgia', 'Arial Narrow', 'Arial', sans-serif; height: 550px; -moz-box-shadow: 0 0 20px #000; width: 324px; float:left;}
#blinds-contv2 #blinds { margin: 0 auto; background: url(spinner.gif) 50% no-repeat; height: 427px; width: 320px; }
#blinds-contv2 #blinds .floom_slice { z-index: 10; }
#blinds-contv2 #blinds .floom_caption { font-size: 1.0em; color: #ddd; font-style: italic; position: relative; text-align: center; width: 100%; top: 15px; }
#blinds-contv2 #blinds .floom_progressbar { font-size: 1px; background: #131718; border-bottom: solid 1px #fff; height: 3px; position: relative; z-index: 1000; width: 0; top: 2px; }
#blinds-contv2 #blinds .floom_container { overflow: hidden; border-bottom: solid 1px #999; border-top: solid 1px #666; }

Title and description

Custom Fields

To conclude temporarily…

Hope this short text will invite you to better understanding of this marvelous tool and ‘embedder’ xili-floom-slideshow plugin. But you need to create your own design adapted to your theme.

Before to answer about the question about coherence or generic design of template tags (with optional echoing).
This recent post is an opportunity to write a short post about our choice of WordPress tools used since more than 4 years as blog or cms.

Some arguments :

Open-source, large community, traceability of the developments, Reactivity of the groups, the possibility of concentrating on the fields of website or data models (CMS) – I do not have particular affinity for the fields of the security or mechanics like ajax

an architecture which makes it possible to build light code for visitor’s webside without interface:
Personally I prefer to write a simple number in css to change a color or a width or copy and paste a template tags in a theme file than to open a wysiwyg heavy desktop application to generate a 30 lines HTML file.

a good data-model totally open for cms architecture (Instead creating new tables, for some plugins, we use the powerful taxonomies architecture).

A philosophy

On the visitor’s webside,
a broad (infinite) range of possible personalizations: from simple blog to cms corporate or groups website.

On the admin (author’s or editor’s) side

Two modes to edit contents (via html or a wysiwg like editor)

On designer’s side – plugin, hook,…

Possible dangers and drifts :

Admin UI :
Client side vs Server side
Client/server versus HTML enriched by Ajax and JS (Excepted iPhone version or unfinished Mars Edit) I am interrogative about the evolution of dashboard and admin UI. Instead to create a powerful client application using the power of the client computer, with a slowdown of flowrate, WP try to recreate an good interface but with the side effects of html and a server shared by lot of users…

Revision, Trash… Good, but if settings are not good, database will contains more drafts than public posts.

Flow rate 3G vs Optical or Cable – mobile or high speed: On visitor’s side, the target is again as 10 years ago, the shortest files as possible

Image processing announced in 2.9 – why not ? but what are consequences on servers. Hope that this features will be optional (I think it is better to prepare images before to sent them…)

Contrasts et contradictions:
If we analyse deeply the previous paragraphs, it is visible that it is not easy to choose the good way for further developments or fixing issues…

Targets:
End users without knowledge in php, html or css are not identical to general or « WP specific » programmers. The choices must leave open the two ways without closing the other.

Upgrading:
Even if I can test the nightly built on a local server, on production server, I wait always the first sub version (i.e 2.8.1)

About the code and the source :

What could we expect?

We know that we are a little slave of the history of the product (obsolete functions) but sometime, for a new branch, a new rewritten template tag or a renewed function is better.
Evaluating consequences of a modification is not easy particularly for the innumerable themes or plugins.
But we find again here the advantages of open source… where each developer participates for the whole communauty.

coherence, robustness, shortest sources,… Theses properties are well known but must be periodically remembered.

writing conventions: unique ID for dev – avoiding conflicts – naming with unique prefix – are some wished properties or recommandations.

param like string or args in array: passing params in a concatenate string or with an array is very powerful and offers future evolutions or personalization. Instead a template tag (like wp_list_pages), the_tags today don’t allow it…

Example of the template tag – the_tags() – with only display list of tags attached to a post in the loop. (three params)

During analyzing this template tag, you discover a deep stacking like a Russian headstock.
And to create the same function but sub-selecting some tags (ie of a language as in xili-tidy-tags plugin) the function is not ‘as is’ usable. Consequently the extension must contain a new function and the theme’s designer must include this new template tag.

Note: a ticket on trac will be soon published with examples. Just need time to prepare and write it.

Download the lastest version 
in bbpress repository xili-bb-np-notification  
or here as file if bbPress server not yet updated :

http://plugins-svn.bbpress.org/xili-new-post-notification/tags/0.9.2/

When studying FAQ of xili-language about some themes with localization (lots of theme’s creator forget to add in tags – localization or international, translation-ready,…), we discover that lot of improvements can be done during creation/design steps to easy transform them in a real multilingual theme.

With examples like with themes – INOVE or ARCLITE, FUSION or ATAHUALPA, we will illustrate here some features that must be considered.

As introduction :

localization and multilingual :

a theme is localizable if the language of the theme can be set by the webmaster according the language of the admin dashboard (in config.php). The .mo file of the language must be present inside the theme’s folder.

A multilingual theme change LIVE his texts when, depending some rules, the language of the post or the visitor’s browser change.
With few modifications, a well made localizable theme can be multilingual with help of xili-language plugin.

Chapter One

What we observe with the themes choosen as example :

ARCLITE, FUSION by digitalnature.ro

After our previous post, thanks to the author who includes the few lines of code inside the source… If xili-language is active, all the theme becomes live- multilingual.
End of august, we hope to provide more improvements to place languages selector (widget) with better design (as permitted by hooks inside xili-language plugins).

INOVE by www.neoease.com

The languages are in a sub-folder named « languages ».

Only one line in functions.php must be modified :

/** l10n */
function theme_init(){
load_theme_textdomain('inove', get_template_directory() . '/languages');
}

to :

421
422
423
424
425
426
427
428
429
430
431
432
433
434

/** l10n */
function theme_init(){
		/*
	* xili-language PLEASE DO NOT DELETE
	* @since 090422
	*/
	if (class_exists('xili_language')) {
		define('THEME_TEXTDOMAIN','inove');
		define('THEME_LANGS_FOLDER','/languages');
	} else {
	   load_theme_textdomain('inove', get_template_directory() . '/languages');	
	}
 
}

But inside the theme, by instance in sidebar.php some texts remain coded as « hard » and don’t incorporate multilingual function __() or _e()… below « Categories » on line 121.

115
116
117
118
119
120
121
122
123

<!-- sidebar east START -->
	<div id="eastsidebar" class="sidebar">
	<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('east_sidebar') ) : ?>
 
		<!-- categories -->
		<div class="widget widget_categories">
			<h3>Categories</h3>
			<ul>
				<?php wp_list_cats('sort_column=name&optioncount=0&depth=1'); ?>

ATAHUALPA by BytesForAll

Here there is only the .pot file, you must create both .po and .mo files for expected languages. You must use PoEdit to complete the file by instance for french (fr_FR.po) or german (de_DE.po) and compile them in .mo (fr_FR.mo, de_DE.mo,…). The theme’s author leave these files inside folder and not in a sub-folder.
the present line of code inside functions.php :

// Load translation file 
load_theme_textdomain('atahualpa');

the lines modified :

3
4
5
6
7
8
9
10

// Load translation file 
 
if (class_exists('xili_language')) {
		define('THEME_TEXTDOMAIN','atahualpa');
		define('THEME_LANGS_FOLDER','');
	} else {
			load_theme_textdomain('atahualpa');
	}

Chapter Two

Dynamic elements and live translations : Categories, tags, widget’s titles must be also dynamic translatable. You can check all these english terms and add it with poEdit but it is far easiest to use xili-dictionary to complete the .po (and .mo) files. See the posts inside this website and also read the review of Jacob here.

as a preliminary conclusion

the core and the hooks
Provided as a core to offer live selections of languages according rules (post or browser), xili-language plugin remains a way to implement rich and customized solutions for CMS or blogs – the hooks are here for that. xili-tidy-tags and xili-dictionary reinforce the toolbox.

webmaster or end-users

The first target of the plugin are webmasters with knowledges in WP (php and html). The future will be for end-users… with the help of theme’s designers.

next steps
After WP 2.8.2 release that introduces some powerful librairies, it will be possible soon to provide plug and play kit for non-developer people.
