wp_get_archives change the output string to spanish

Update: Actually, looks like the “echo” option is either due to be added soon or was added in 2.6. See: http://trac.wordpress.org/ticket/5654

Unfortunately, I am using WordPress MU, so I’m not sure a localized version would work.

Also, I imagine these won’t work for multi-lingual blogs as well, so this may not work for krisnrg. Right?

I believe the solution would be same for a multi-language single blog as it would be for WordPress MU.

In any event, I manage to figure something out. It isn’t ideal, but it seems to work.

First, you’ll need a new version of wp_get_archives that adds an echo option. This could be added as a plugin or just in custom functions.php file for your template.

Here is the code I used (basically just copied from the ticket I mentioned above):

<?php

function wp_get_archives_new($args = '') {
	global $wpdb, $wp_locale;

	$defaults = array(
		'type' => 'monthly', 'limit' => '',
		'format' => 'html', 'before' => '',
		'after' => '', 'show_post_count' => false,
    'echo' => 1
	);

	$r = wp_parse_args( $args, $defaults );
	extract( $r, EXTR_SKIP );

	if ( '' == $type )
		$type = 'monthly';

	if ( '' != $limit ) {
		$limit = absint($limit);
		$limit = ' LIMIT '.$limit;
	}

	// this is what will separate dates on weekly archive links
	$archive_week_separator = '–';

	// over-ride general date format ? 0 = no: use the date format set in Options, 1 = yes: over-ride
	$archive_date_format_over_ride = 0;

	// options for daily archive (only if you over-ride the general date format)
	$archive_day_date_format = 'Y/m/d';

	// options for weekly archive (only if you over-ride the general date format)
	$archive_week_start_date_format = 'Y/m/d';
	$archive_week_end_date_format	= 'Y/m/d';

	if ( !$archive_date_format_over_ride ) {
		$archive_day_date_format = get_option('date_format');
		$archive_week_start_date_format = get_option('date_format');
		$archive_week_end_date_format = get_option('date_format');
	}

  // Place to accrue text if we're not echoing...
  $output = ''; 

	//filters
	$where = apply_filters('getarchives_where', "WHERE post_type = 'post' AND post_status = 'publish'", $r );
	$join = apply_filters('getarchives_join', "", $r);

	if ( 'monthly' == $type ) {
		$query = "SELECT DISTINCT YEAR(post_date) AS <code>year</code>, MONTH(post_date) AS <code>month</code>, count(ID) as posts FROM $wpdb->posts $join $where GROUP BY YEAR(post_date), MONTH(post_date) ORDER BY post_date DESC $limit";
		$key = md5($query);
		$cache = wp_cache_get( 'wp_get_archives' , 'general');
		if ( !isset( $cache[ $key ] ) ) {
			$arcresults = $wpdb->get_results($query);
			$cache[ $key ] = $arcresults;
			wp_cache_add( 'wp_get_archives', $cache, 'general' );
		} else {
			$arcresults = $cache[ $key ];
		}

			$afterafter = $after;

				$url	= get_month_link($arcresult->year,	$arcresult->month);
				$text = sprintf(__('%1$s %2$d'), $wp_locale->get_month($arcresult->month), $arcresult->year);
				if ( $show_post_count )
					$after = '&nbsp;('.$arcresult->posts.')' . $afterafter;
				$output .= get_archives_link ( $url, $text, $format, $before, $after );
			}
		}
	} elseif ('yearly' == $type) {

				}

  if ( $echo )
    echo $output;
  else
 	  return $output;
}

?>

Then, I created a function to translate the months (I am working in Farsi, but Spanish should work just as well). You could place this in either the plugin or the functions.php file I mentioned.

//translate_date()
//Gets the featured post and outputs the html
function translate_date($content, $language_option) {
  $english = array('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December');

  if($language_option = "farsi")
    $language = array('ژانویه', 'feb', 'مارس', 'آوریل', 'مه', 'ژوئن', 'ژوئیه', 'اوت', 'سپتامبر', 'اکتبر', 'نوامبر', 'دسامبر');

  return str_replace($english, $language, $content);

}

Finally, this is the code in the sidebar of my template:

echo translate_date(wp_get_archives_new('type=monthly&show_post_count=1&echo=0'), "farsi");

Now, this isn’t perfect, because you’ll have to call the function in a bunch of other places, such as the headers of archive pages. Since the_time() automatically echos, you need to replace that. Here is the code I used for the_time():

echo translate_date(apply_filters('the_time', get_the_time("F"), "F"), "farsi");

The “F” is the type of date display, in this case just the full month. You could also do “j F Y”, which would look like “1 Enero 2008”. Just make sure to change the date display in both places.

I hope this helps.
