将分页添加到基于标签然后按类别排序的wordpress中

Question

我设法添加了一个显示类别的下拉列表。我希望这些类别显示与分配的标签相关的产品，但我无法让分页与类别和标签一起使用。分页不经常出现。请帮我提供代码。

<div class="category-dropdown">

                <form id="tool-category-select" class="tool-category-select" method="get">

                    <?php
                    // Create and display the dropdown menu.
                    wp_dropdown_categories(
                        array(
                            'orderby'         => 'NAME', // Order the items in the dropdown menu by their name.
                            'taxonomy'        => 'category', // Only include posts with the taxonomy of 'category'.
                            'name'            => 'category', // Change this to the
                            'show_option_all' => 'All category', // Text the dropdown will display when none of the options have been selected.
                            'selected'        => km_get_selected_taxonomy_dropdown_term(), // Set which option in the dropdown menu is the currently selected one.
                            'tag'             => 'maxxio',
                        ) );
                    ?>

                    <input type="submit" value="View" />
                </form>

            </div>


                <?php $category_in_taxonomy_term = km_get_category_in_taxonomy_term(); ?>

                <!-- If posts were found, -->
                <?php if ( $category_in_taxonomy_term->have_posts() ) : ?>

                    <!-- Loop through every post. -->
                    <?php while ( $category_in_taxonomy_term->have_posts() ) : $category_in_taxonomy_term->the_post(); ?>

                        <!-- Display each post's title and content - you can change this section to display whatever post content you want. -->
                        <div class="prod_item">
                                    <a href="<?php the_permalink(); ?>">
                                        <span class="title"><?php the_title(); ?></span>
                                        <?php the_post_thumbnail( 'prod_thumb' ); ?>
                                        <span class="know_more">KNOW MORE <i class="fa fa-angle-right"></i></span>
                                    </a>

                                </div>

                    <?php endwhile; 

                  ?>

                    <?php 
                    if (function_exists("pagination")) {
                      pagination($custom_query->max_num_pages);
                  } 
                  wp_reset_postdata(); ?>

                <?php endif; ?>
