如何使用我的类别过滤器向我的category.php添加更多帖子

Question

I have created a filter category with ajax in category.php and I want to limit the posts to 10 and add a button to show more posts in every category inside the loop.

I used the post_per_page but my category filter is not working and shows all the posts randomly not categorize

<ul class="categories-filters">
    <?php if (is_category()) { $cat=g et_query_var( 'cat'); $this_category=g et_category($cat); $this_category=w p_list_categories( 'hide_empty=0&hierarchical=false&order=ASC&orderby=title&show_count=0&title_li=&use_desc_for_title=1&child_of='.$this_category->cat_ID."&echo=0"); if($this_category !='
    <li>No categories</li>') { echo '
    <ul class="ul-menu">'.$this_category.'</ul>'; } } ?></ul>?></ul>
<?php if(have_posts() ) { ?>
<div id="main-content">
    <div id="inside">
        <?php $i=0 ; ?>
        <?php while (have_posts()) : the_post(); // modified to work with 3 columns // output an open <div>if($i % 3 == 0) { ?>
        <div class="row ng-row">
            <?php } ?>
            <div class="col-md-4 col-sm-12 col-xs-12 half">
                <a href="<?php the_permalink();?>">
                    <div class="img-holder">
                        <?php if ( has_post_thumbnail() ) { the_post_thumbnail(); } else { echo '<img src="' . get_bloginfo( 'stylesheet_directory' ) . '/assets/img/thumbnail-default-rev.jpg" />'; } ?>
                        <h2 class="project-title"><?php the_title() ?></h2>
                        <small>see more ></small>
                    </div>
                </a>
            </div>
            <?php $i++; if($i !=0 && $i % 3==0 ) { ?>
        </div>
        <!--/.row-->
        <div class="clearfix"></div>
        <?php } ?>
        <?php endwhile; } wp_reset_query(); ?>

Is there any way to add some arguments like post_per_page without breaking my ajax category filter and add a button which is show more posts respective to my categories?

</div>
