我如何对此进行分页?它是wordpress模板中的代码,我用它来获取第一个字母的帖子。我只想要10页。     

$postids=$wpdb->get_col($wpdb->prepare("
SELECT      ID
FROM        $wpdb->posts
WHERE       SUBSTR($wpdb->posts.post_title,1,1) = %s
ORDER BY    $wpdb->posts.post_title",$first_char)); 

if ($postids) {
$args=array(
  'post__in' => $postids,
  'post_type' => 'post',
  'post_status' => 'publish',
  'posts_per_page' => -1,
  'caller_get_posts'=> 1
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
 echo 'List of Posts Titles beginning with the letter '. $first_char;
  while ($my_query->have_posts()) : $my_query->the_post(); ?>
    <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
    <?php
  endwhile;
}
wp_reset_query();  // Restore global post data stomped by the_post().
}
?>

我知道我们可以控制不。 posts.But如何分页? 通常在wordpress模板中的普通循环中,它的工作原理如下

<?php if ( $wp_query->max_num_pages > 1 ) : ?>
    <div id="nav-above" class="navigation">
        <div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">&lt;&lt;</span> Show More', 'twentyten' ) ); ?></div>
        <div class="nav-next"><?php previous_posts_link( __( 'Show Previous <span class="meta-nav">&gt;&gt;</span>', 'twentyten' ) ); ?></div>
    </div><!-- #nav-above -->
<?php endif;  ?>

但在这种情况下它确实起作用。

这是一个应该有帮助的例子:

<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$sticky=get_option('sticky_posts');
$args=array(
   'cat'=>3,
   'caller_get_posts'=>1,
   'post__not_in' => $sticky,
   'paged'=>$paged,
   );
query_posts($args);
?>

query_posts
