• Hi,

    I have created a custom template for a specific category. On that page I query the category and list out its posts. Right now it just lists 10 posts per page and uses the default WP pagination.

    However, I’d like to change it so that it lists posts by year. So default will list all posts in 2013. Then pagination will go back 2012, 2011, 2010, etc. and list all posts in those years.

    An added tricky part is it needs to sort and group the years not by published date, but by a custom field.

    Any ideas?

    Thanks!

    Is this a category template:
    http://codex.wordpress.org/Template_Hierarchy#Category_display

    or a custom page template:
    http://codex.wordpress.org/Page_Templates#Custom_Page_Template

    Do all the posts in the specific category have the custom field by which you want to order the posts?

    Hi keesiemeijer,

    It is a custom page template, and yes they all use the same custom field for the date.

    Here is what I am using..

    <?php
    					$i = 1;
    					$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
    					query_posts( array(
    									  'cat' => '17',
    									  'post__not_in' => array($post_ID),
    									  'order' => 'DESC',
    									  'orderby' => 'meta_value_num',
    									  'meta_key' => 'event_date',
    									  'posts_per_page' => '12',
    									  'paged' => $paged
    								 ) );
    				?>
    				<?php while ( have_posts() ) : the_post(); ?>
    				<?php
    					$get_event_date = get_post_meta($post->ID, 'event_date', true);
    					$get_event_date = substr($get_event_date,0,-3);
    					$event_date = date("m/d/Y", $get_event_date); 
    
    				?>

    I’ve just created a plugin that you can use. Download it here http://keesiemeijer.wordpress.com/date-pagination/

    Activate the plugin and try it with a custom query (WP_Query):

    <?php
    $i = 1;
    // not needed (plugin takes over pagination)
    //$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
    
    $args = array(
    	'cat' => '17',
    	'post__not_in' => array( $post_ID ),
    	'order' => 'DESC',
    	'orderby' => 'meta_value_num',
    	'meta_key' => 'event_date',
    	'date_pagination_type' => 'yearly',
    	//'posts_per_page' => '12', why show 12 posts?
    	//'paged' => $paged
    );
    
    // the custom query
    $the_query = new WP_Query( $args );
    
    // set the max_num_pages variable
    if ( function_exists( 'km_dp_set_max_num_pages' ) )
        km_dp_set_max_num_pages( $the_query );
    ?>
    				<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
    <?php
    $get_event_date = get_post_meta( $post->ID, 'event_date', true );
    $get_event_date = substr( $get_event_date, 0, -3 );
    $event_date = date( "m/d/Y", $get_event_date );
    ?>

    Thanks keesiemeijer… I activated the plugin, used the code above, but all it’s doing now is just listing all the posts on one page. Any ideas?

    Moderator keesiemeijer

    (@keesiemeijer)

    I forgot some code when posting, does your code contain this (see edited example above):

    // set the max_num_pages variable
    if ( function_exists( 'km_dp_set_max_num_pages' ) )
        km_dp_set_max_num_pages( $the_query );

    That’t strange, just tested it with your code in a page template and it seems to work. So now it is listing all the posts on the page from any year?

    Where do you get the $post_ID variable from? Try changing it to $post->ID. Also change this:

    <div class="alignright"><?php next_posts_link('More ยป') ?></div>

    to this:

    <div class="alignright"><?php next_posts_link('More ยป', $the_query->max_num_pages) ?></div>

    http://codex.wordpress.org/Function_Reference/next_posts_link#Usage_when_querying_the_loop_with_WP_Query

    Maybe try deactivating all plugins but this one to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).

    Moderator keesiemeijer

    I’ve tested some more and it seems you have to set the $paged variable in a static front page. Is this the page template for a static front page? I’ve updated the plugin so it works also for a static front page. Download the plugin once more at the same location and try it with this:

    <?php
    $i = 1;
    
    // current page
    if ( get_query_var( 'paged' ) ) { $paged = get_query_var( 'paged' ); }
    elseif ( get_query_var( 'page' ) ) { $paged = get_query_var( 'page' ); }
    else { $paged = 1; }
    
    $args = array(
    	'cat' => '17',
    	'post__not_in' => array( $post->ID ),
    	'order' => 'DESC',
    	'orderby' => 'meta_value_num',
    	'meta_key' => 'event_date',
    	'date_pagination_type' => 'yearly',
    	'paged' => $paged,
    );
    
    // the custom query
    $the_query = new WP_Query( $args );
    
    // set the max_num_pages variable
    if ( function_exists( 'km_dp_set_max_num_pages' ) )
    	km_dp_set_max_num_pages( $the_query );
    ?>
    <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
    <!-- rest of loop -->

    Excellent, that seems to be working!

    Is there a way to alter the pagination so that it goes like this…

    2013 – 2012 – 2011 … 2009

    Instead of Next > and Prev ?

    Moderator keesiemeijer

    (@keesiemeijer)

    @ikjosh
    I added and removed some functions from the plugin.
    Remove this snippet from your template:

    // set the max_num_pages variable
    if ( function_exists( 'km_dp_set_max_num_pages' ) )
    	km_dp_set_max_num_pages( $the_query );

    It is no longer needed (and function removed) to get the correct number of pages for a custom query.

    Re-upload the new plugin and see the last example in the documentation on how you can add the year labels to pagination functions.

    keesiemeijer,

    Is it possible to view the current year for the page you’re on?

    I tried using km_dp_date_pagination_get_date(‘Y’, $posts) but it didn’t work for me, it returned the previous year.

    Any ideas?

    I greatly appreciate this plugin, it’s exactly what I was needing!

    Moderator keesiemeijer

    (@keesiemeijer)

    I’ve updated the plugin to also let you get the current year with the km_dp_get_current_date_label(); function:
    http://keesiemeijer.wordpress.com/date-pagination/#functions

    <?php
    echo 'Year: ' . km_dp_get_current_date_label('Y');
    ?>

    Get the new version 0.2 here:
