<?php wp_get_archives( array( 
	'type' => 'postbypost',

	'format' => '',
	'before' => '<li>',
	'after' => '</li>' 
)); ?>
</ul>

WordPress Numeric Pagination

Here’s how to add numeric pagination on your WordPress pages.

Add this code to functions.php.

function pagination($pages = '', $range = 4) {
	$showitems = ($range * 2)+1;
	global $paged;
	if(empty($paged)) $paged = 1;
	if($pages == '') {
		global $wp_query;
		$pages = $wp_query->max_num_pages;
		if(!$pages) {
			$pages = 1;
		}
	}
	if(1 != $pages) {
		echo '<p><div class="pagination"><span>Page' . $paged . ' of  ' . $pages . '</span>   ';
		if($paged > 2 && $paged > $range+1 && $showitems < $pages) echo '<a href="' . get_pagenum_link(1) . '"><< First</a>';
		if($paged > 1 && $showitems < $pages) echo '<a href="'.get_pagenum_link($paged - 1).'">< Previous</a>';
		for ($i=1; $i <= $pages; $i++) {
			if (1 != $pages &&( !($i >= $paged+$range+1 || $i <= $paged-$range-1) || $pages <= $showitems )) {
				echo ($paged == $i)? '<span class="current">' . $i . '</span>' : '<a href="' . get_pagenum_link($i) . '"class="inactive">' . $i . '</a>';
			}
		}
		if ($paged < $pages && $showitems < $pages) echo '<a href="' . get_pagenum_link($paged + 1) . '">Next ></a>';
		if ($paged < $pages-1 && $paged+$range-1 < $pages && $showitems < $pages) echo '<a href="' . get_pagenum_link($pages) . '">Last >></a>';
		echo '</div></p>';
	}
}

To display, comment out ‘the_post_navigation’ function and add the ‘pagination’ function instead in your template files.

//the_posts_navigation();
pagination();

WP_Query Reverse Sort

Here’s how to reverse sort WP_Query. Order by ID. Reverse sort by ASC intead of DESC.

  $args = array (
    'cat' => 8, 
    'year' => $year, 
    'orderby' => 'ID',
    'order' => 'ASC', 
    'posts_per_page' => -1, 
    'paged' => $paged, 
    's' => $searchterm 
  );
  $category_posts = new WP_Query($args);

Run SQL in Bash

Here’s an example on how to run MySQL commands from Bash.

mysql dbname -e "UPDATE wp_options SET option_value='http://domain.com' WHERE option_name='home'";
mysql dbname -e "UPDATE wp_options SET option_value='http://domain.com' WHERE option_name='siteurl'";

The example updates WordPress’ home and siteurl. Script contains no password. It’s using .my.cnf config file.

CloudFront SSL Certificates

If you have SSL on your website, you can import your own SSL certificates into CloudFront, which is a content delivery network service by AWS. You will need to work a few AWS services to get it working.

  • CloudFront – create a distribution
  • Route 53 – create a hosted zone and add a CNAME
  • Certificate Manager – import your SSL certificate

Finally, on the WordPress side, enable the use CloudFront in your SuperCache plugin.

Seems simple, but you’ll need some patience to get it working.

Look at your HTML source to see if your CDN is really working.
