我试图在单个页面上输出类别及其帖子，但出于某种原因，所有类别中的帖子都在每个类别中重复，我做错了什么这里的代码：

<?php
        #Template Name: food
        get_header();
 ?>

<?php
        $taxonomy = \'category\';
        $param_type = \'category__in\';

        $term_args = array(
                \'orderby\' => \'name\',
                \'order\' => \'ASC\',
                \'exclude\' => 1
        );
        $terms = get_terms($taxonomy, $term_args);
?>

<div class="row">
        <?php if($terms) : ?>

                <?php $counter = 0; foreach($terms as $term) : $counter++; ?>

                        <?php
                                $args = array(
                                        \'$param_type\' => array($term->term_id),
                                        \'post_type\' => \'food\',
                                        \'post_status\' => \'publish\',
                                        \'posts_per_page\' => -1
                                );

                                $my_query = null;
                                $my_query =  new Wp_Query($args);
                        ?>

                        <?php if($my_query->have_posts()) : ?>

                                        <?php if($counter == 2): ?>
                                                <ul class="menu-list sixcol last">
                                        <?php $counter = 0; else: ?>
                                                <ul class="menu-list sixcol">
                                        <?php endif; ?>

                                                <h3><?php echo $term->name; ?></h3>

                                                        $post_meta_data = get_post_custom($post->ID);

                                                 ?>

        <?php endif; ?>
</div>
<?php get_footer(); ?>
