Displaying post by category from query with pagination - php

Question

Can you tell me what is the problem with my code? my code is to display the custom post by category. my code is perfectly working fine. but when I put a pagination, the code is error now.
<?php
$ourteam_category_check = '4';
$paged = (int) get_query_var('paged'); --> I inserted this
$niche_ourteam_args = array(
'posts_per_page' => 10,
'paged' => $paged, --> I inserted this
'post_type' => 'shop',
'orderby' => 'post_date',
'order' => 'DESC',
'post_status' => 'publish',
'meta_query' => array(
array(
'key' => '_thumbnail_id',
'compare' => 'EXISTS'
),
),
'tax_query' => array(
array(
'taxonomy' => 'shop_cat',
'field' => 'term_id',
'terms' => $ourteam_category_check
),
),
);
$niche_ourteam = new WP_Query($niche_ourteam_args);
while ($niche_ourteam->have_posts()) : $niche_ourteam->the_post();
?>
--> echo all the items from category 4 here
<?php endwhile; endif; ?>
<div class="page-nav-area">
<?php
if( function_exists('wp_pagenavi') ) {
wp_pagenavi(array('query' => $the_query));

Try this code is working fine for my side
<?php if (have_posts()): while (have_posts()) : the_post(); ?>
<div class="the_loop">
<?php
if ( get_query_var('paged') ) {
$paged = get_query_var('paged');
} elseif ( get_query_var('page') ) { // 'page' is used instead of 'paged' on Static Front Page
$paged = get_query_var('page');
} else {
$paged = 1;
}
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$loop = new WP_Query(
array(
'post_type' => 'shop',
'posts_per_page' => get_option('posts_per_page'),
'paged' => $paged,
'tax_query' => array(
array(
'taxonomy' => 'category',
'field' => 'term_id',
'terms' => $cat->cat_ID, // your categories or you can use 'category__in' => array(2,6)
),
),
)
);
?>
<?php if ($loop->have_posts()): while ($loop->have_posts()) : $loop->the_post(); ?>
// Loop code goes here.
<?php endwhile; ?>
<?php if ($loop->max_num_pages > 1) : // custom pagination ?>
<?php
$orig_query = $wp_query; // fix for pagination to work
$wp_query = $loop;
$big = 999999999;
echo paginate_links(array(
'base' => str_replace($big, '%#%', get_pagenum_link($big)),
'format' => '?paged=%#%',
'current' => max(1, get_query_var('paged')),
'total' => $wp_query->max_num_pages
));
$wp_query = $orig_query; // fix for pagination to work
?>
<?php endif; ?>
<?php wp_reset_postdata(); else: echo '<p>'.__('Sorry, no posts matched your criteria.').'</p>'; endif; ?>
</div>
<?php endwhile; ?>
<?php endif; ?>
