我有这个短代码，它可以很好地处理帖子，但我需要修改它，以获取自定义帖子类型和自定义分类的参数。

<?php
// [blog_posts]
function shortcode_latest_from_blog($atts, $content = null) {
    $sliderrandomid = rand();
    extract(shortcode_atts(array(
        "posts" => \'8\',
        "columns" => \'4\',
        "category" => \'\',
        "style" => \'text-normal\',
        "image_height" => \'auto\',
        "show_date" => \'true\',
        "excerpt" => \'true\',
    ), $atts));
    ob_start();
    ?>

        <div class="row column-slider">
            <div id="slider_<?php echo $sliderrandomid ?>" class="iosSlider blog-posts <?php if($style  == \'text-overlay\') { ?>slider-center-arrows<?php } ?>" style="min-height:<?php echo $image_height; ?>;height:<?php echo $image_height; ?>;">
