WordPress分页工作，但不在主页上

Question

I have a function that works fine for pagination on a search page:

function 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+5 || $i <= $paged-$range-5) || $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>
";
     }
}

And I call it using this code after the wp_query:

<?php pagination($pages = $wp_query->max_num_pages); ?>

The wp_query has paged' => $paged, in the arguments.

But, when I try and paginate the homepage the pagination doesn't actually work. It'll link to the correct URL, but the posts don't actually change.

The home page has been made a page template (not using index.php) and in settings the front page has been set to the correct page.

But I have no idea why it's not paginating on the homepage but is on the search page. If I set the search page to the front page in WP Settings that pagination also breaks.

[EDIT] (code for query, as requested below)

$args = array(  
    // general
    'post__in' => $postIDs,
    'post_type' => 'event',
    'posts_per_page' => 10,
    'paged' => $paged,

    'meta_key' => $_SESSION['search']['sort-key'],
    'orderby' => $_SESSION['search']['sort-by'],
    'order' => 'ASC',


    // what input
    'title_like' => $_SESSION['search']['keyword'],
    // change to sub categories/ keywords

    // category filter
    'tax_query' => array(
        array(
            'taxonomy' => 'main-cat',
            'field' => 'slug',
            'terms' => $mainCat
        )
        // add sub category search too
    ),

        // date filter
        'meta_query' => array(
        array(
            'key' => 'date_%_start-date',
            'value' => $when,

            'type' => 'NUMERIC'
        ),
        array (

                $minidescription = html_entity_decode($minidescription);

                echo '<p>' . $minidescription . '</p>';
            ?>

        </div>

    </div>  

    <?php $plus++; ?>

I don't see in your code where you check if the guery_var contains a paged variable, you should add this code to check if it exists and if the value is added to it.

this is the code:

if ( get_query_var('paged') ) { $paged = get_query_var('paged'); } else if ( get_query_var('page') ) {$paged = get_query_var('page'); } else {$paged = 1; }

This is also a starting point for debugging any issues with wordpress pagination.
