在Wordpress类别中覆盖每页默认帖子的问题

Question

我被困住了。我一直在尝试使用query_posts( array('category_name'=>'news','posts_per_page' => 2, 'paged' => $paged)

覆盖类别存档上的默认返回帖子数

问题是它在第一页上返回了正确的结果，当我转到较旧的查询$wp_query->request查询时，而不是显示LIMIT 2,2显示LIMIT 10,10，表明它正在进行每页使用默认帖子。

<?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('category'=>'news','posts_per_page' => 4, 'paged' => $paged)); 

                        if (have_posts()) : ?>  <div class="arch-wrap">
                <?php
                                while ($query->have_posts()) :
$query->the_post(); ?>

                    <div class="post" id="post-<?php the_ID(); ?>">
                        <h2 class="title"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php
the_title_attribute(); ?>"><?php
the_title(); ?></a></h2>
                        <span class="top-post-meta"><small>Posted on

the_author() ?></small></span>
                                                <div class="cover">
                        <div class="entry">
                            <?php  ?><div style="margin-left:10px;"class="image-frame page-image-frame fr"><?php //echo wp_get_post_image();?></div><?php 
?><?php get_post_excerpt(500) ?>
                        </div>


                    </div>
                                                <div class="clear"></div>
                    </div>




                <?php endwhile; ?>  </div>
                 <div id="navigation">
                                      <?php                                 

        wp_reset_query(); if(function_exists('wp_pagenavi')) {
wp_pagenavi(); } ?> </div>


            <?php else : ?>

                <h2 class="center">Not Found</h2>
                <p>Sorry, but there are currently no posts found here.</p>

            <?php endif;  ?>

        </div> <?php get_sidebar('right');
?>   <?php get_footer(); ?>
