Multiple loop with independent pagination and permalinks

Hi everybody,

i tried to find something about Multiple loop with independent pagination in the forums and nothing; please, you say me if i am wrong.

I found this and this but both topics are not resolved. Nothing either searching google.

After some work I found a solution by myself. Different pagination for each loop in a two loops page works fine now, but not to implement permalinks in them.

So my code produces two numerical pagination system using WordPress paginate_links() native function. For the first loop, prepared with query_posts to get posts from cat 1, the links are like this:

http://example.com/?cat=1&paged=2

For the second one, prepared to list posts from cat 2, like this:

http://example.com/?cat=2&paged=2

So, the navigation between pages works fine. You can see here, in Projects and Blog tabs.

The loops code:

<?php /* begin first loop */
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$query_cat = 1;
query_posts("posts_per_page=2&cat=$query_cat&paged=$paged");
if ( have_posts() ) : while ( have_posts() ) : the_post();
/* first loop HTML code */

endwhile;

include "pagination.php";

endif;
wp_reset_query();
/* end first loop */

/* begin second loop */
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$query_cat = 2;
query_posts("posts_per_page=5&order=ASC&cat=$query_cat&paged=$paged");
if ( have_posts() ) : while ( have_posts() ) : the_post();
/* second loop HTML code */

endwhile;

include "pagination.php";

endif;
wp_reset_query();
/* end second loop */
?>

And the content of the pagination.php file:

<?php
$wp_query->query_vars['paged'] > 1 ? $current = $wp_query->query_vars['paged'] : $current = 1;
$current_cat = $query_cat;

$pagination = array(
        'base' => @add_query_arg( array('cat' => $current_cat, 'paged' => '%#%'), $_SERVER['SERVER_NAME'] ),
        'format' => '',
        'total' => $wp_query->max_num_pages,
        'current' => $current,
        'show_all' => false,
        'prev_text' => __('«'),
        'next_text' => __('»'),
        'type' => 'plain',
        );

echo paginate_links($pagination);
?>

All this code works fine, but if i add the following code to implement permalinks, then brokes:

global $wp_rewrite;
if( $wp_rewrite->using_permalinks() )
      $pagination['base'] = user_trailingslashit( trailingslashit( remove_query_arg('s',get_pagenum_link(1) ) ) . "page/%#%/", 'paged');

I have also tried to change the las line into the following with no results:

$pagination['base'] = user_trailingslashit( trailingslashit( remove_query_arg('s',$current_uri ) ) . "$current_cat_name/", 'cat' . "page/%#%/", 'paged');

Any idea?
