在函数中复制并粘贴此函数。php
if ( ! function_exists( \'display_all_products_from_all_categories\' ) ) {
function display_all_products_from_all_categories() {
// Get all the categories for Custom Post Type Product
$args = array(
\'post_type\' => \'product\',
\'orderby\' => \'id\',
\'order\' => \'ASC\'
);
$categories = get_categories( $args );
foreach ($categories as $category) {
?>
<div class="<?php echo $category->slug; ?>">
<!-- Get the category title -->
<h3 class="title"><?php echo $category->name; ?></h3>
<!-- Get the category description -->
<div class="description">
<p><?php echo category_description( get_category_by_slug($category->slug)->term_id ); ?></p>
</div>
<ul class="mhc-product-grid">
<?php
// Get all the products of each specific category
$product_args = array(
\'post_type\' => \'product\',
\'orderby\' => \'id\',
\'order\' => \'ASC\',
\'post_status\' => \'publish\',
\'category_name\' => $category->slug //passing the slug of the current category
);
$product_list = new WP_Query ( $product_args );
?>
<?php while ( $product_list -> have_posts() ) : $product_list -> the_post(); ?>
<li class="product <?php the_field( \'product_flavor\' ); ?>">
<a href="<?php the_permalink(); ?>" class="product-link">
<!-- if the post has an image, show it -->
<?php if( has_post_thumbnail() ) : ?>
<?php the_post_thumbnail( \'full\', array( \'class\' => \'img\', \'alt\' => get_the_title() ) ); ?>
<?php endif; ?>
<!-- custom fields: product_flavor, product_description ... -->
<h3 class="title <?php the_field( \'product_flavor\' ); ?>"><?php the_title(); ?></h3>
<p class="description"><?php the_field( \'product_description\' ); ?></p>
</a>
</li>
<?php endwhile; wp_reset_query(); ?>
</ul>
</div>
<?php
}
}
}
然后从模板中的任意位置调用它，方法是：
display_all_products_from_all_categories();
