Help editing recent posts Wordpress widget for diplay in all three languages ​​at once

Question

Link to the site: http://nuestrafrontera.org/wordpress/

I want the feed of the latest message headers to appear in the sidebar for all three languages ​​separated by the language. So, for example, in the Recent Posts section, the sidebar will have “English” and then the last 3 posts in English, then “Español” and the last 3 in Spanish and then in French. Everything is listed in a column and displayed on all pages with a sidebar in all languages.

I am using the latest version of Wordpress with the WPML plugin.

I believe that the Wordpress widget for recent posts should be modified to do this. Here is the code (from wp-includes / default-widgets.php):

class WP_Widget_Recent_Posts extends WP_Widget { function WP_Widget_Recent_Posts() { $widget_ops = array('classname' => 'widget_recent_entries', 'description' => __( "The most recent posts on your blog") ); $this->WP_Widget('recent-posts', __('Recent Posts'), $widget_ops); $this->alt_option_name = 'widget_recent_entries'; add_action( 'save_post', array(&$this, 'flush_widget_cache') ); add_action( 'deleted_post', array(&$this, 'flush_widget_cache') ); add_action( 'switch_theme', array(&$this, 'flush_widget_cache') ); } function widget($args, $instance) { $cache = wp_cache_get('widget_recent_posts', 'widget'); if ( !is_array($cache) ) $cache = array(); if ( isset($cache[$args['widget_id']]) ) { echo $cache[$args['widget_id']]; return; } ob_start(); extract($args); $title = apply_filters('widget_title', empty($instance['title']) ? __('Recent Posts') : $instance['title']); if ( !$number = (int) $instance['number'] ) $number = 10; else if ( $number < 1 ) $number = 1; else if ( $number > 15 ) $number = 15; $r = new WP_Query(array('showposts' => $number, 'nopaging' => 0, 'post_status' => 'publish', 'caller_get_posts' => 1)); if ($r->have_posts()) : ?> <?php echo $before_widget; ?> <?php if ( $title ) echo $before_title . $title . $after_title; ?> <ul> <?php while ($r->have_posts()) : $r->the_post(); ?> <li><a href="<?php the_permalink() ?>" title="<?php echo esc_attr(get_the_title() ? get_the_title() : get_the_ID()); ?>"><?php if ( get_the_title() ) the_title(); else the_ID(); ?> </a></li> <?php endwhile; ?> </ul> <?php echo $after_widget; ?> <?php wp_reset_query(); // Restore global post data stomped by the_post(). endif; $cache[$args['widget_id']] = ob_get_flush(); wp_cache_add('widget_recent_posts', $cache, 'widget'); } function update( $new_instance, $old_instance ) { $instance = $old_instance; $instance['title'] = strip_tags($new_instance['title']); $instance['number'] = (int) $new_instance['number']; $this->flush_widget_cache(); $alloptions = wp_cache_get( 'alloptions', 'options' ); if ( isset($alloptions['widget_recent_entries']) ) delete_option('widget_recent_entries'); return $instance; } function flush_widget_cache() { wp_cache_delete('widget_recent_posts', 'widget'); } function form( $instance ) { $title = esc_attr($instance['title']); if ( !$number = (int) $instance['number'] ) $number = 5; ?> <p><label for="<?php echo $this->get_field_id('title'); ?>"><?php _e('Title:'); ?></label> <input class="widefat" id="<?php echo $this->get_field_id('title'); ?>" name="<?php echo $this->get_field_name('title'); ?>" type="text" value="<?php echo $title; ?>" /></p> <p><label for="<?php echo $this->get_field_id('number'); ?>"><?php _e('Number of posts to show:'); ?></label> <input id="<?php echo $this->get_field_id('number'); ?>" name="<?php echo $this->get_field_name('number'); ?>" type="text" value="<?php echo $number; ?>" size="3" /><br /> <small><?php _e('(at most 15)'); ?></small></p> <?php } }

I am not familiar with the WPML plugin, but if you have language specific categories, you can simply do this:

 ... <ul class="recent-english-posts"> <?php $loop = new WP_Query('cat=' . get_category_by_slug('english')->term_id . '&showposts=3'); if($loop->have_posts()): while($loop->have_posts()): $loop->the_post(); ?> <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php endwhile; else: ?> No English posts yet! <?php endif; ?> </ul> ... <ul class="recent-spanish-posts"> <?php $loop->query('cat=' . get_category_by_slug('spanish')->term_id . '&showposts=3'); if($loop->have_posts()): while($loop->have_posts()): $loop->the_post(); ?> <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php endwhile; else: ?> No Spanish posts yet! <?php endif; ?> </ul> ... <ul class="recent-espanol-posts"> <?php $loop->query('cat=' . get_category_by_slug('espanol')->term_id . '&showposts=3'); if($loop->have_posts()): while($loop->have_posts()): $loop->the_post(); ?> <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php endwhile; else: ?> No Espanol posts yet! <?php endif; ?> </ul> ... 

By sidebar.php this code in the sidebar.php theme, you hopefully do it. But what if you want it as a widget? in my opinion there are two solutions:

First solution: As you mentioned in your question update, you can branch out the kernel! and change the standard WordPress post widget. Here you can replace the original widget() method of the WP_Widget_Recent_Posts class:

 ... function widget($args, $instance) { $cache = wp_cache_get('widget_recent_posts', 'widget'); /* pre-saving language-specific ids for ease of use & code readability ofcourse! */ $cat_ids = array( 'en'=>get_category_by_slug('english')->term_id, 'sp'=>get_category_by_slug('spanish')->term_id, 'es'=>get_category_by_slug('espanol')->term_id ); if ( !is_array($cache) ) $cache = array(); if ( isset($cache[$args['widget_id']]) ) { echo $cache[$args['widget_id']]; return; } ob_start(); extract($args); $title = apply_filters('widget_title', empty($instance['title']) ? __('Recent Posts') : $instance['title']); if ( !$number = (int) $instance['number'] ) $number = 10; else if ( $number < 1 ) $number = 1; else if ( $number > 15 ) $number = 15; /* recent english posts loop */ $r = new WP_Query(array('cat' => $cat_ids['en'], 'showposts' => $number, 'nopaging' => 0, 'post_status' => 'publish', 'caller_get_posts' => 1)); if ($r->have_posts()) : ?> <?php echo $before_widget; ?> <?php if ( $title ) echo $before_title . $title . $after_title; ?> <ul> <?php while ($r->have_posts()) : $r->the_post(); ?> <li><a href="<?php the_permalink() ?>" title="<?php echo esc_attr(get_the_title() ? get_the_title() : get_the_ID()); ?>"><?php if ( get_the_title() ) the_title(); else the_ID(); ?> </a></li> <?php endwhile; ?> </ul> /* recent spanish posts loop */ $r->query(array('cat' => $cat_ids['sp'], 'showposts' => $number, 'nopaging' => 0, 'post_status' => 'publish', 'caller_get_posts' => 1)); if ($r->have_posts()) : ?> <?php echo $before_widget; ?> <?php if ( $title ) echo $before_title . $title . $after_title; ?> <ul> <?php while ($r->have_posts()) : $r->the_post(); ?> <li><a href="<?php the_permalink() ?>" title="<?php echo esc_attr(get_the_title() ? get_the_title() : get_the_ID()); ?>"><?php if ( get_the_title() ) the_title(); else the_ID(); ?> </a></li> <?php endwhile; ?> </ul> /* recent espanol posts loop */ $r->query(array('cat' => $cat_ids['es'], 'showposts' => $number, 'nopaging' => 0, 'post_status' => 'publish', 'caller_get_posts' => 1)); if ($r->have_posts()) : ?> <?php echo $before_widget; ?> <?php if ( $title ) echo $before_title . $title . $after_title; ?> <ul> <?php while ($r->have_posts()) : $r->the_post(); ?> <li><a href="<?php the_permalink() ?>" title="<?php echo esc_attr(get_the_title() ? get_the_title() : get_the_ID()); ?>"><?php if ( get_the_title() ) the_title(); else the_ID(); ?> </a></li> <?php endwhile; ?> </ul> <?php echo $after_widget; ?> <?php wp_reset_query(); // Restore global post data stomped by the_post(). endif; $cache[$args['widget_id']] = ob_get_flush(); wp_cache_add('widget_recent_posts', $cache, 'widget'); } ... 

But I do not prefer to use such a solution, changing the kernel is not a good idea! It might also be bad practice due to portability considerations, while you can rewrite WordPress widgets!

Second but preferred solution! In your functions.php topic, put the following code:

 <?php function widget_mytheme_recent_posts(){ ?> <!-- your new widget code will go there replace this comment by the first block of code in this answer, take care of php code blocks! --> <?php } //end of widget_mytheme_recent_posts() if(function_exists('register_sidebar_widget')) register_sidebar_widget(__('Recent Posts'), 'widget_mytheme_recent_posts'); /* the rest of functions.php code will go here, maybe sidebar registering! */ ?> 

Hope this helps;)
