Pagination Not Displaying on Custom Term Archive

Question

I am trying to achieve pagination on a custom template I have that displays on an archive of terms.

It appears to be working because when I navigate to mysite/taxonomy/page/2/ or 3,4,5 etc. the pagination works. It also shows the correct number of terms per page. However, there are not any actual pagination links showing on the bottom of my page and it sounds like there is supposed to be.

I am following this tutorial as well as the Codex instructions, but I have to be missing something. Can someone please help figure out what? My simplified code is below.

<?php get_header(); ?>

<div class="container">
<div class="row">
  <div class="col-md-12">

<div class="row">
  <div class="col-md-9">
<h2>Index Post Type Archive </h2>
<hr/>

    <span class="visible-lg">

        <div class="row">
    <?php

    if ( get_query_var( 'paged' ) )
    $paged = get_query_var('paged');
else if ( get_query_var( 'page' ) )
    $paged = get_query_var( 'page' );
else
    $paged = 1;

$per_page    = 12;
$number_of_terms = count( get_terms( '100list' ) ); // This counts the total number terms in the taxonomy with a function)
$offset      = $per_page * ( $paged - 1) ;

    $libargs=array(
      'orderby'           => 'name',
         'order'             => 'ASC',
        'hide_empty'        => 0,
        'exclude'           => array(16, 20, 22,25, 27, 28, 30, 4, 42, 7, 43 ), //* Enter ID's of parent categories to exclude from list

Answer 1

There where one or two problems with the code that I sorted out

Big changes

• $number_of_terms = count( get_terms( '100list' ) ); is replaced by $number_of_terms = wp_count_terms( '100list' );. The reason is that wp_count_terms is already there to return the term count natively

• get_categories is replaced by get_terms as get_terms accepts the offset parameter

• Removed if (function_exists("pagination")) {. It serves no purpose, and it is the culprit that hides your pagination links.

• Changed 'current' => $paged, to 'current' => max( 1, get_query_var('paged') ),

• Cleaned up your indentation on the important part of your code. There seems to be closing </div>'s missing that you have to sort out.

So, here is the code that works. I did test it on my install and works perfectly

<?php get_header(); ?>

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

Answer 2

The problem is with function_exists("pagination"). There is no function named pagination in Wordpress. You are using the function paginate_links(). So, you should Replace that with

function_exists("paginate_links")
