Paging The HemingwayEx Home Page

By default, the HemingwayEx theme only shows 2 posts on the home page. This is all well & good except for the fact that you can’t use the paging (next & previous) links on your home page to show older posts as well.

If you want to get the paging links working, then here’s 3 steps to achieve that goal.

Step #1:

Create a new PHP file (you can do this easily with a simple text editor like Notepad). Name it custom_hem_home_query.php. Now copy & paste the following code into it.

<?php

/*
 * Plugin Name: Custom HemingwayEx Home Query
 * Plugin URI: http://moggy.laceous.com/2007/07/29/paging-the-hemingwayex-home-page/
 * Description: Gives you the ability to use the paging links on your homepage
 * Version: 0.1
 * Author: Moggy
 * Author URI: http://moggy.laceous.com
 */

add_filter('query_string', 'custom_hem_home_query');

function custom_hem_home_query($query_string) {
	global $wp_query;
	$wp_query->parse_query($query_string);
	if ($wp_query->is_home) {
		global $hemingwayEx;
		$category_id = $hemingwayEx->get_asides_category_id();
		if (is_null($category_id)) {
			$query_string .= '&posts_per_page=2';
		}
		else {
			$query_string .= '&posts_per_page=2&cat=-' . $category_id;
		}
	}
	return $query_string;
}

?>

Save the file & upload it to your wp-content/plugins folder. When you’re ready… activate the plugin.

Step #2:

Now we have to remove the custom query from the wp-content/themes/hemingwayEx index.php file. Find the following code in the index.php file:

// Here is the call to only make two posts show up on the homepage REGARDLESS of your options in the control panel
$category_id = $hemingwayEx->get_asides_category_id();
is_null($category_id) ? query_posts('showposts=2') : query_posts('showposts=2&cat=-' . $category_id);

Simply comment out those lines so it looks like this:

// Here is the call to only make two posts show up on the homepage REGARDLESS of your options in the control panel
//$category_id = $hemingwayEx->get_asides_category_id();
//is_null($category_id) ? query_posts('showposts=2') : query_posts('showposts=2&cat=-' . $category_id);

Step #3:

Now you just need to add the paging links to your index.php file. Something like this should work:

<div class="navigation">
  <?php next_posts_link('&laquo; Previous Entries') ?>
  <?php previous_posts_link('Next Entries &raquo;') ?>
</div>

One final note:

You could also wrap the code from steps 2 & 3 with an if statement like the following if you want to be able to dynamically enable & disable the plugin.

if (function_exists('custom_hem_home_query')) {
  // put code here
}
