Con WooCommerce,desidero visualizzaretutte le categoriein unnegozio comeintestazioni,contuttii loroprodottielencati di seguitoin unelenconon ordinato. Èpossibilefarlo? Ho visto alcune cose chemi consentono di visualizzare unelenco di categorie o unelenco diprodottiper una categoria specifica,maniente chepossa scorreretuttonelmodo descritto.

Ecco cosa sto utilizzando attualmenteperelencaretutte le categorie:

 <?php
$args = array(
    'number'     => $number,
    'orderby'    => $orderby,
    'order'      => $order,
    'hide_empty' => $hide_empty,
    'include'    => $ids
);
$product_categories = get_terms( 'product_cat', $args );
$count = count($product_categories);
if ( $count > 0 ){
    foreach ( $product_categories as $product_category ) {
        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</h4>';
    }
}
?>

With WooCommerce, I want to display all the categories in a store as headings, with all of their products listed below in an unordered list. Is this possible to do? I've seen a few things that'll let me display a list of categories or a list of products for a specific category, but nothing that'll loop through everything the way I described.

Here's what I'm currently using to list all categories:

<?php
$args = array(
    'number'     => $number,
    'orderby'    => $orderby,
    'order'      => $order,
    'hide_empty' => $hide_empty,
    'include'    => $ids
);
$product_categories = get_terms( 'product_cat', $args );
$count = count($product_categories);
if ( $count > 0 ){
    foreach ( $product_categories as $product_category ) {
        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</h4>';
    }
}
?>

- Hai semplicementebisogno di un ciclo di loop.All'interno deltuo `foreach ()`,esegui unnuovo `WP_Query ()`perprenderetuttii prodottiin queltermine ..e poi scorrere quelli.
  
  You simply need a loop of loops. Inside your `foreach()`, run a new `WP_Query()` to grab all the products in that term.. and then loop through those.

- Penso di capire comefarlo,manon riesco atrovarenulla sull'elencazione deiprodottiper categoria con PHP (tutto quello chepossotrovare è un'assurdità di shortcode).Sepuoimostrarmi come appare quel codice,dovreiesserein grado di capireil resto.
  
  I think I understand how to do this, but I can't find anything about listing products by category with PHP (all I can find is shortcode nonsense). If you can show me what that code looks like, I should be able to figure out the rest.

- Non haibisogno di uno shortcode,elencarei prodottiper categoria è solo un [Tax Query] (http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters).
  
  You don't need a shortcode, listing products by category is just a [Tax Query](http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters).

- Sapevo dinon averbisogno di uno shortcode,stavo dicendo cheeratutto ciò chepotevotrovare,il chenonera di aiuto.Il link che haifornito sembrapromettente,ciprovo domanie ti riferisco,grazie.
  
  I knew I didn't need a shortcode, I was saying that's all I could find, which was unhelpful. That link you provided looks promising, I'll give it a shot tomorrow and report back, thanks.

  Ok. If you are still stuck, edit your question with your new coding attempt and I'll take a look.

Capito! Il codice seguenteelenca automaticamentetutte le categoriee ognipost di categoria!

 $args = array(
    'number'     => $number,
    'orderby'    => 'title',
    'order'      => 'ASC',
    'hide_empty' => $hide_empty,
    'include'    => $ids
);
$product_categories = get_terms( 'product_cat', $args );
$count = count($product_categories);
if ( $count > 0 ){
    foreach ( $product_categories as $product_category ) {
        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</a></h4>';
        $args = array(
            'posts_per_page' => -1,
            'tax_query' => array(
                'relation' => 'AND',
                array(
                    'taxonomy' => 'product_cat',
                    'field' => 'slug',
                    // 'terms' => 'white-wines'
                    'terms' => $product_category->slug
                )
            ),
            'post_type' => 'product',
            'orderby' => 'title,'
        );
        $products = new WP_Query( $args );
        echo "<ul>";
        while ( $products->have_posts() ) {
            $products->the_post();
            ?>
                <li>
                    <a href="<?php the_permalink(); ?>">
                        <?php the_title(); ?>
                    </a>
                </li>
            <?php
        }
        echo "</ul>";
    }
}

Figured it out! The code below automatically lists all categories and each categories posts!

$args = array(
    'number'     => $number,
    'orderby'    => 'title',
    'order'      => 'ASC',
    'hide_empty' => $hide_empty,
    'include'    => $ids
);
$product_categories = get_terms( 'product_cat', $args );
$count = count($product_categories);
if ( $count > 0 ){
    foreach ( $product_categories as $product_category ) {
        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</a></h4>';
        $args = array(
            'posts_per_page' => -1,
            'tax_query' => array(
                'relation' => 'AND',
                array(
                    'taxonomy' => 'product_cat',
                    'field' => 'slug',
                    // 'terms' => 'white-wines'
                    'terms' => $product_category->slug
                )
            ),
            'post_type' => 'product',
            'orderby' => 'title,'
        );
        $products = new WP_Query( $args );
        echo "<ul>";
        while ( $products->have_posts() ) {
            $products->the_post();
            ?>
                <li>
                    <a href="<?php the_permalink(); ?>">
                        <?php the_title(); ?>
                    </a>
                </li>
            <?php
        }
        echo "</ul>";
    }
}

Bello.Se vuoi diventare veramentepazzopotresti voleresaminare l '[API Transients] (https://codex.wordpress.org/Transients_API) ... cheti aiuterebbe aevitare dieseguire cosìtante query a ogni caricamento dipagina.

Nice. If you want to get really crazy you might want to look into the [Transients API](https://codex.wordpress.org/Transients_API)... that would help keep you from running so many queries on every page load.

@AlyssaReyes categories don't inherently have thumbnails; did you set up a custom field for your categories for this? Could you post this in a new question with more detail and send me the link so I can better understand?

Grazie amico,mi hai risparmiato unpo 'ditempoe mi haimessonellagiusta direzione.L'unicomodopermigliorare questa risposta è utilizzare la classe di queryincorporata di WooCommerce: `WC_Product_Query`,invece di` WP_Query`,quindi utilizzare un ciclo `foreach`invece di un ciclo` while`.Peri motivi,dai un'occhiata alla documentazione di Githubper la query: https://github.com/woocommerce/woocommerce/wiki/wc_get_products-and-WC_Product_Query#description,ma l'essenza è:> "èprobabile che le query WP_Queriespersonalizzaterompereil codicenelle versionifuture di WooCommercementrei dati si spostano versotabellepersonalizzateperprestazionimigliori.

Thanks man, you saved me some time and set me in the right direction. The only way I could improve this answer is to use WooCommerce's built-in query class: `WC_Product_Query`, instead of `WP_Query`, then use a `foreach` loop instead of a `while` loop. For reasons why, take a look at the Github documentation for the query: https://github.com/woocommerce/woocommerce/wiki/wc_get_products-and-WC_Product_Query#description, but the gist is: > "custom WP_Queries queries is likely to break your code in future versions of WooCommerce as data moves towards custom tables for better performance."
