Question

我对分页有疑问，在单击数字下一个按钮时，下一页显示与上一页相同的帖子。

帖子查询基本上使用自定义类别下拉列表，并从特定的帖子标签获取。

分页能够从类别和标签获取帖子，但无法动态更改帖子。

请帮助。

<?php 
wp_dropdown_categories( 'show_count=0&hierarchical=1&exclude=1,203,202,199,198,197,196&hide_empty=1&value_field=analgesic-anti-inflammatory&show_option_none=Select Category' ); ?>
<script type="text/javascript">

    var dropdown = document.getElementById("cat");
    function onCatChange() {
        if ( dropdown.options[dropdown.selectedIndex].value > 0 ) {
            location.href = "?cat="+dropdown.options[dropdown.selectedIndex].value;
        }
    }
    dropdown.onchange = onCatChange;

</script>
<?php
wp_reset_query();
$post_tag = 'futura';
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$args = array( 'post_type' => 'post', 'posts_per_page' => 8,'tag'=> $post_tag, 'taxonomy' => 'category', 'category__in' => $_GET['cat'], 'max_num_pages' => '50', 'offset' =>20, 'paged'=>$paged);
query_posts($args);
$custom_query = new WP_Query( $args );

// The Loop
while ( $custom_query->have_posts() ) : $custom_query->the_post();
?>
    <div class="prod_item">
        <a href="<?php the_permalink(); ?>">

            <span class="know_more">KNOW MORE<i class="fa fa-angle-right"></i></span>
        </a>

    </div>
<?php 
endwhile;
if (function_exists("pagination")) {
    pagination($custom_query->max_num_pages);
} 
wp_reset_query();

function.php

function pagination($pages = '', $range = 2)
{
    $showitems = ($range * 2)+1;
    global $paged;
    if(empty($paged)) $paged = 1;

    if(1 != $pages)

        if($paged > 1 && $showitems < $pages) echo "<a href='".get_pagenum_link($paged - 1)."'>&lsaquo; Previous</a>";
        for ($i=1; $i <= $pages; $i++)
        {
            if (1 != $pages &&( !($i >= $paged+$range+1 || $i <= $paged-$range-1) || $pages <= $showitems ))

        }
        if ($paged < $pages && $showitems < $pages) echo "<a href=\"".get_pagenum_link($paged + 1)."\">Next &rsaquo;</a>";
        if ($paged < $pages-1 && $paged+$range-1 < $pages && $showitems < $pages) echo "<a href='".get_pagenum_link($pages)."'>Last &raquo;</a>";
        echo "</div>\n";
    }
}
