wp e-commerce group product by category

Question

Sorry for my bad english. I have WP 3.3.1 & wp-e-commerce.3.8.7.6.2. On the products page (which use wpsc-products_page.php template) I have list of products. I want to group this products by category. For example:

**Cat1
Product 1
Product 2

** Cat2
Product 1
Product 2

** Cat3
Product 1
Product 2

I try to use this method, but it`s does not work

add_filter('posts_join', create_function('$a', 'global $wpdb; return $a . " INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb->term_relationships.object_id) INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id) ";'));
add_filter('posts_where', create_function('$a', 'global $wpdb; return $a . " AND $wpdb->term_taxonomy.taxonomy = \'wpsc_product_category\'";'));
add_filter('posts_orderby', create_function('$a','global $wpdb; return "$wpdb->term_taxonomy.term_id DESC";'));
query_posts('');

Thank you all in advance for your reply!

Solution

Try the below code.

/* ----------

Continue code

<?php
/* Check if this is the products page not the category or single page  */
if( is_products_page() && wpsc_is_product() && (!wpsc_is_in_category()) && (!wpsc_is_single_product()) ) {
    /* Get all the categories for wp e-commerce products */
    $wpec_product_categories = get_terms( 'wpsc_product_category', 'hide_empty=0&parent=0');
    foreach($wpec_product_categories as $wpec_categories){
        $wpec_term_id = $wpec_categories->term_id;
        $wpec_term_name = $wpec_categories->name;
        $wpec_term_slug = $wpec_categories->slug;

        //Skip the categories term(which comes default in wp e-commerce
        if($wpec_term_slug == 'categories') {
            continue;
        }

        //Set the args array
        $wpec_args = array(
            'post_status' => 'publish',
            'post_type'   => 'wpsc-product',
            'numberposts' => 12,
            'showposts' => 12,
            "wpsc_product_category" => $wpec_term_slug
        );

        $wpec_categoryProducts = new WP_Query($wpec_args);
    ?>
        <div class="wpec_productcat_name"><h3><?php echo $wpec_term_name; ?></h3></div>

    <?php /** start the category wise - products loop here */?>
    <?php while ($wpec_categoryProducts->have_posts()) : $wpec_categoryProducts->the_post();
        global $wpsc_custom_meta, $wpsc_variations;
        $wpsc_custom_meta = new wpsc_custom_meta( get_the_ID() );
        $wpsc_variations = new wpsc_variations( get_the_ID() );
    ?>
        <div class="default_product_display product_view_<?php echo wpsc_the_product_id(); ?> <?php echo wpsc_category_class(); ?> group"> 

/* ----------
-------------
Continue code - product display
-------------
---------- */

        </div><!--close default_product_display-->
    <?php endwhile; ?>
    <?php /** end the product loop here */?>     

<?php
}
else {
?>
    <?php /** start the wp e-commerce default product loop here */ ?>
    <?php while (wpsc_have_products()) :  wpsc_the_product(); ?>
        <div class="default_product_display product_view_<?php echo wpsc_the_product_id(); ?> <?php echo wpsc_category_class(); ?> group">

/* ----------
-------------
Continue code - products display(same code as above)
-------------
---------- */

        </div><!--close default_product_display-->
    <?php endwhile; ?>
    <?php /** end the product loop here */?> 

<?php
} //End of else block for products page checking
?>

The above code you have to use inside the product template of WP E-Commerce.

Steps:

– Open the wpsc-products_page.php file. – Find the products loop statement in the code.

<?php /** start the product loop here */?>
<?php while (wpsc_have_products()) :  wpsc_the_product(); ?>

– Find the products loop end statement.

<?php endwhile; ?>
<?php /** end the product loop here */ ?>

– Copy the whole block in between while and endwhile for the product loop. – Then enclose those copied code inside the below mentioned condition. – Save and check the products page.

Hi, what if I want to use that code as an API (webservice) to return products of given category ID? Thanx in advance.

@malloc: Yes you can create a function which accepts the category-id and then query the products, run a loop to format it according to your need and return. Example: $term = get_term( $category_id, 'wpsc_product_category'); $wpec_term_slug = $term->slug; $args = array( 'post_status' => 'publish', 'post_parent' => 0, 'post_type' => 'wpsc-product', 'wpsc_product_category' => $wpec_term_slug ); $products = get_posts($args);
