爲什麼第2頁的單詞分頁制動？

Question

我有一個有分頁的類別循環。第一頁總是正確的。一旦我翻過第一頁，就會混合在一起。另外，頁面數量總是錯誤的。

<?php 
    global $paged; 
    $cat = get_the_category(); 
    $catSlug = $cat[1]->slug; 
    $query = new WP_Query(array('category_name' => $catSlug,'posts_per_page' => 20,'paged' => $paged)); 
?> 
<?php 
    while ($query->have_posts()) : 
     $query->the_post(); 
?> 
     <li><a href="<?php the_permalink(); ?>" title="<?php printf(esc_attr__('%s', 'starkers'), the_title_attribute('echo=0')); ?>" rel="bookmark"><?php the_title(); ?></a></li> 
<?php endwhile; ?> 
    </ul> 
<?php 
    global $wp_query; 

    $catSlug = $cat[0]->slug; 
    $total_pages = $wp_query->max_num_pages; 

    if ($total_pages > 1){ 

    $current_page = max(1, get_query_var('paged')); 

    echo paginate_links(array(
     'base' => get_pagenum_link(1) . '%_%', 
     'format' => '?paged=%#%', 
     'current' => $current_page, 
     'total' => $total_pages, 
     'add_args' => array('category_name' => $catSlug) 
    )); 
} 
?>

想通了：

query_posts（）用來paginate_links（）工作。我必須改變query_posts而不是使用wp_query，像這樣：

<?php 
    global $query_string; 
    query_posts($query_string . '&posts_per_page=20'); 
?> 
<?php if (have_posts()) while (have_posts()) : the_post(); ?> 
     <li><a href="<?php the_permalink(); ?>" title="<?php printf(esc_attr__('%s', 'starkers'), the_title_attribute('echo=0')); ?>" rel="bookmark"><?php the_title(); ?></a></li> 
<?php endwhile; ?> 
    </ul> 
<?php 
    global $wp_query; 

$total_pages = $wp_query->max_num_pages; 

if ($total_pages > 1){ 

    $current_page = max(1, get_query_var('paged')); 

    echo paginate_links(array(
     'base' => get_pagenum_link(1) . '%_%', 
     'format' => '?paged=%#%', 
     'current' => $current_page, 
     'total' => $total_pages, 
    )); 
} 
?>
