I am trying to pass args to archive.php so that I can order the posts, set the number of posts, etc..

but the query is done like this

<?php if (have_posts()): ?>
 <?php while (have_posts()): the_post();?> 

if it wasnew \WP_Query($args); i was able to pass the args here but this can't be done in archive.php template?

The pre_get_posts hook can be used to modify queries before they're run. You can use $query->set() to set arguments on the WP_Query object, and $query->is_main_query() in the callback to limit your changes to the main query:

add_action(
    'pre_get_posts',
    function( $query ) {
        if ( ! is_admin() && $query->is_main_query() ) {
            $query->set( 'posts_per_page', 12 );
        }
    }
);

You can't target specific templates, but if you want the change to only affect archives, you can use $query->is_archive(), which will be true for date, taxonomy and post type archives, or if you only want to apply the changes to the category archives, you can use $query->is_category(). Many of the normal conditional functions are available as methods for checking the current query.

  • thank you. Just having doubt in default how WordPress decides the order for its archives? – Latheesh V M Villa Sep 8 '19 at 10:38

    Everything’s ordered by date by default. Same as the normal blog. – Jacob Peattie Sep 8 '19 at 12:37

this is the code from my archive.php file:

$args = array( 
    'posts_per_page' => 3,
    'order' => 'DESC'
);

$myposts = new WP_Query($args);

<?php if ( $myposts->have_posts() ) : ?>

    <?php while ( $myposts->have_posts() ) : $myposts->the_post(); ?>

    <?php endwhile; ?>
    <?php wp_reset_postdata(); ?>

<?php else: ?>

    //If there is no post for this category / tag

<?php endif; ?>

I hope I understood the question well and that I can help you.

Best regards.

  • yes. but how can i pass args to this query? Say if i wanted to order them by title and show only 3 posts with pagination? – Latheesh V M Villa Sep 7 '19 at 19:52
  • I updated the answer, could this work for you? – Matteo Feduzi Sep 7 '19 at 19:56
  • if you change it like that it will become a new loop. archive.php will show the same result for all archives. – Latheesh V M Villa Sep 7 '19 at 19:59
  • Can you better explain the result you would like to achieve? Unfortunately I don't understand English very well. – Matteo Feduzi Sep 7 '19 at 20:00
  • you can't put new WP_Query($args); in archive.php it works without it. I am just checking if there is any method to pass $args to this loop. – Latheesh V M Villa Sep 7 '19 at 20:03
