按类别分页

Question

我只对一个类别“procesos”进行了分页，这就是代码：

<?php if(has_term('procesos', 'dslc_projects_cats')): ?>

    <?php 

        $args = array(
            'posts_per_page'  => 7,
            'post_type' => 'dslc_projects',
            'tax_query' => array('dslc_projects_cats', 'field' => 'id', 'terms' => 'procesos')
        );

        $processes = get_posts($args);
        $ids = array();

        foreach ($processes as $process) {
            $ids[] += $process->ID;
        }

        $thisindex = array_search($post->ID, $ids);

        //var_dump($ids);
        $previd = $ids[$thisindex-1];
        $nextid = $ids[$thisindex+1];

    ?>
    <div class="row">
        <div class="container inner-pagination">
            <div class="col-xs-6">
                <?php 
                    if(!empty($previd))
                        echo '<a rel="prev" href="'.get_permalink($previd).'"> &laquo; '.get_the_title($previd).'</a>';
                ?>
            </div>
            <div class="col-xs-6 text-right">
                <?php 
                    if(!empty($nextid))
                        echo '<a rel="next" href="'.get_permalink($nextid).'">'.get_the_title($nextid).' &raquo </a>';
                ?>
            </div>
        </div>
    </div>

   <?php endif; ?>

分页仅出现在带有“procesos”类别的帖子中，我将代码修改为：

<?php 

    $args = array(
        'posts_per_page'  => 13,
        'post_type' => 'dslc_projects',

    );

    $processes = get_posts($args);
    $ids = array();
    foreach ($processes as $process) {
        $ids[] += $process->ID;
    }

    $thisindex = array_search($post->ID, $ids);

    //var_dump($ids);
    $previd = $ids[$thisindex-1];
    $nextid = $ids[$thisindex+1];
?>

其余的是相同的，现在我在所有帖子中都有分页并继续（没有分类）：http://globalarmor.com.mx/project-view/desmontaje/

我希望按类别分页，就像之前一样，但是在所有类别中（有四个）。我怎样才能做到这一点？
