Message:

I have been trying to add numeric pagination to my posts page which are filtered by category. The problem is that pagination won't appear when I call it. Pagination works perfectly fine when I use previous_posts_link and next_posts_link but this is not excatly what I want to achieve. What am I missing here?

My filtered category page.

<?php

// Get post ID





$post_type = get_post_type( $post->ID );



// Get category ID

$category_id = get_cat_ID(single_cat_title('', false));



// Wordpress pagination

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;



// WP_Query arguments

$args_news = array (

    'post_type'             => array( 'post' ),

    'pagination'            => true,

    'posts_per_page'        => '2',

    'orderby'               => 'date',

    'paged'                 => $paged,

    'cat'                   => $category_id,

    

);



// The Query

$query = new WP_Query( $args_news );



// The Loop

if ( $query->have_posts() ) {

    while ( $query->have_posts() ) {

        

        $query->the_post(); ?>

        

     <?php get_template_part('categorytwo',get_post_format()); ?>

<?php }



} else { 

    // no news found

}

?>



<div class="pagination">

    <?php my_pagination(); ?>

    </div>



<?php

// Reset postdata

wp_reset_postdata();



?>

This pagination function works fine on my index.php page when I call it out.



<?php

if ( get_query_var('paged') ) { $paged = get_query_var('paged'); }

elseif ( get_query_var('page') ) { $paged = get_query_var('page'); }

else { $paged = 1; }



query_posts(array(

    'post_type'      => 'post', // You can add a custom post type if you like

    'paged'          => $paged,

    'posts_per_page' => 4

));



if ( have_posts() ) : ?>



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



    <?php get_template_part('catalog',get_post_format()); ?>



<?php endwhile; ?>





<div class="pagination">

    <?php my_pagination(); ?>

    </div>



<?php else : ?>



    <?php // no posts found message goes here ?>

<?php wp_reset_query(); // add this ?>

<?php endif; ?>

Functions.php

if ( ! function_exists( 'my_pagination' ) ) :

    function my_pagination() {

        global $wp_query;



        $big = 999999999; // need an unlikely integer



        echo paginate_links( array(

            'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),

            'format' => '?paged=%#%',

            'current' => max( 1, get_query_var('paged') ),

            'prev_text' => __('« PREV'),

                        'next_text' => __('NEXT »'),

            'total' => $wp_query->max_num_pages



        ) );

    }

endif;

When I call it out on my index.php page it works fine.

<?php

if ( get_query_var('paged') ) { $paged = get_query_var('paged'); }

elseif ( get_query_var('page') ) { $paged = get_query_var('page'); }

else { $paged = 1; }



query_posts(array(

    'post_type'      => 'post', // You can add a custom post type if you like

    'paged'          => $paged,

    'posts_per_page' => 4

));



if ( have_posts() ) : ?>



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



    <?php get_template_part('catalog',get_post_format()); ?>



<?php endwhile; ?>





<div class="pagination">

    <?php my_pagination(); ?>

    </div>



<?php else : ?>



    <?php // no posts found message goes here ?>

<?php wp_reset_query(); // add this ?>

<?php endif; ?>

My Answer:
To add numeric pagination to your custom loop in WordPress, you can use the `paginate_links()` function. Here's an example of how you can modify your custom loop to include numeric pagination:

php
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
$args = array(
'post_type' => 'post',
'cat' => 1, // Replace 1 with the category ID you want to filter by
'posts_per_page' => 10,
'paged' => $paged
);

$query = new WP_Query( $args );

if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
// Display your post content here
}

// Add numeric pagination
echo paginate_links( array(
'total' => $query->max_num_pages
) );

wp_reset_postdata();
} else {
// No posts found
}
?>


In this code snippet, we first define the `$paged` variable to get the current page number. We then set up the arguments for the custom loop, including the category ID, posts per page, and the current page number.

Next, we create a new `WP_Query` object with the arguments and loop through the posts. After displaying the post content, we use the `paginate_links()` function to generate numeric pagination based on the total number of pages in the query.

Make sure to replace `1` with the actual category ID you want to filter by. You can also customize the `paginate_links()` function with additional parameters to style the pagination links as needed.

By following this approach, you should be able to add numeric pagination to your custom loop in WordPress for filtered category pages.
