Question

I am working with wordpress pagination. i have problem with code. pagination is working fine on main page. but showing 404 error on tag page and category page. when i go to any tag or category its showing first time ok but when i navigate to next page its showing 404 page error.

here is pagination code.

    <?php
function kriesi_pagination($pages = '', $range = 2)
{  
     $showitems = ($range * 2)+1;  

     global $paged;
     if(empty($paged)) $paged = 1;

     if($pages == '')
     {
         global $wp_query;
         $pages = $wp_query->max_num_pages;
         if(!$pages)
         {
             $pages = 1;
         }
     }   

     if(1 != $pages)
     {
         echo "<div class='pagination'>";
         if($paged > 2 && $paged > $range+1 && $showitems < $pages) echo "<a href='".get_pagenum_link(1)."'>&laquo;</a>";
         if($paged > 1 && $showitems < $pages) echo "<a href='".get_pagenum_link($paged - 1)."'>&lsaquo;</a>";

         for ($i=1; $i <= $pages; $i++)
         {
             if (1 != $pages &&( !($i >= $paged+$range+1 || $i <= $paged-$range-1) || $pages <= $showitems ))
             {
                 echo ($paged == $i)? "<span class='current'>".$i."</span>":"<a href='".get_pagenum_link($i)."' class='inactive' >".$i."</a>";
             }
         }

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

<?php global $wp_query;
$args = array_merge( $wp_query->query_vars, array( 'post_type' => 'fahrzeug' ) );
query_posts( $args );
if ( have_posts() ) : while ( have_posts() ) : the_post(); 
$omc_review_enable =  get_post_meta(get_the_ID(), 'omc_review_enable', true);
$omc_final_score =  get_post_meta(get_the_ID(), 'omc_final_score', true);
$omc_final_percentage = $omc_final_score * 20 ;
$format = get_post_format();
if ( false === $format )
$format = 'standard';
?>      

<article class="omc-blog-two omc-half-width-category" id="post-<?php the_ID(); ?>">

      if (!$displayed and $h_sticky && $home_page == 1) {
        echo $h_sticky;
        $displayed = true;
      } 
    ?>  
    <div class="omc-resize-290 omc-blog">

Answer 1

我敢打赌，您应该在存档页面上使用paginate_links（）函数而不是get_pagenum_link（）...

Answer 2

1) Login as the admin in WordPress.

2)Go to the Settings tab.

3)Go to the Reading tab. 4)Change the Blog pages show at most from the default 10 to any number *less than 10. For example, 5.

5)Save the changes.

View the blog.

edit the number to less than 10, hope it helps you out. It fixed mine.

while debugging i found out that default posts per page option should be less than any custom posts_per_page in query_posts function. That's all. Weird, but that's the fact.
