Holen Sie sich die Produktliste einer bestimmten Kategorie-ID

Obamich konntenicht den richtigen Wegfinden,um die Liste aller Produktefüreine bestimmte Kategorie-ID (nicht Kategorie-Name) zuerhalten.

Der Code,denich zum Abrufen der Kategorieliste verwende,lautet wiefolgt:

$args = array( 'orderby' => $orderby, 'order' => $order, 'hide_empty' => 0, 'include' => $ids, 'parent' => 0, ); $categories = get_terms( 'product_cat', $args );
$ Füreine bestimmte Kategorie-ID (z. B. 47) konnteichjedoch keinen Wegfinden,um die relevanten Produkte zuerhalten. Ich habe Folgendes versucht:

$args = array( 'posts_per_page' => 5, 'offset'=> 1, 'category' => 47 ); $products = get_posts( $args ); echo var_dump($products);
$productsgibt immer 0 zurück,wasfalschist,daich weiß,dasseseinige Produkte unter der Kategoriemit der ID 47gibt. Irgendwelche Ideen,wieichmeinen Code reparieren kann?
I couldn't find the right way to get the list of all products for a given category ID (not category name).

The code I am using to get the categories list is the following, it works fine:

$args = array( 'orderby' => $orderby, 'order' => $order, 'hide_empty' => 0, 'include' => $ids, 'parent' => 0, ); $categories = get_terms( 'product_cat', $args );

However, now for a given category ID (say 47), I couldn't find the way to get its relevant products. I tried the following way:

$args = array( 'posts_per_page' => 5, 'offset'=> 1, 'category' => 47 ); $products = get_posts( $args ); echo var_dump($products);

Debugging the $products array returns always 0 which is wrong since I know there is some products under the category with ID 47. Any ideas how to fix my code?

Ich vermute,das Hauptproblembesteht darin,dass Sie das Objekt WP_Query anstelle von get_posts() verwenden sollten. Letzteresgibt standardmäßignur Artikelmit dem Post-Typ post zurück,nicht Produkte,

Beieiner Kategoriemit der ID 26 würde derfolgende Code die Produkte zurückgeben (WooCommerce 3+):

     $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        ),
        array(
            'taxonomy'      => 'product_visibility',
            'field'         => 'slug',
            'terms'         => 'exclude-from-catalog', // Possibly 'exclude-from-search' too
            'operator'      => 'NOT IN'
        )
    )
);
$products = new WP_Query($args);
var_dump($products);

Sebastian Infrüheren Versionen von WooCommerce wurde die Sichtbarkeit als Metafeldgespeichert,sodass der Code wiefolgt lautet:

     $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'meta_query'            => array(
        array(
            'key'           => '_visibility',
            'value'         => array('catalog', 'visible'),
            'compare'       => 'IN'
        )
    ),
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        )
    )
);
$products = new WP_Query($args);
var_dump($products);

Sebastian Hiergeben wirnur sichtbare Produkte zurück,12pro Seite.

Sehen Sie sich http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters Weitere Informationen zur Funktionsweise des Kategorie-Targetingsfinden Sie häufig -esistnützlicher,esper Slug alsnach ID abzurufen!

I suspect the main problem is that you should be using the WP_Query object rather than get_posts(). The later by default only returns items with a post_type of post not products,

So given a category with ID 26, the following code would return it's products (WooCommerce 3+):

    $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        ),
        array(
            'taxonomy'      => 'product_visibility',
            'field'         => 'slug',
            'terms'         => 'exclude-from-catalog', // Possibly 'exclude-from-search' too
            'operator'      => 'NOT IN'
        )
    )
);
$products = new WP_Query($args);
var_dump($products);

In earlier versions of WooCommerce the visibility was stored as a meta field, so the code would be:

    $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'meta_query'            => array(
        array(
            'key'           => '_visibility',
            'value'         => array('catalog', 'visible'),
            'compare'       => 'IN'
        )
    ),
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        )
    )
);
$products = new WP_Query($args);
var_dump($products);

Here we are only returning visible products, 12 per page.

Have a look through http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters for more details about how the category targeting works - it's often more useful to retrieve it by slug than by ID!

Lösung hatfunktioniert.Schöne Erklärung.

Solution worked. Nice explanation.

Ab Woocommerce 3 wird die Sichtbarkeitin Taxonomie anstelle von Metageändert,sodass Sie diemeta_queryin tax_query ändernmüssen.Siehe https://wordpress.stackexchange.com/a/262628/37355.

As of Woocommerce 3, visibility is changed to taxonomy instead of meta so you need to change the meta_query to tax_query. See https://wordpress.stackexchange.com/a/262628/37355.

Ihre Schlussfolgerung zuget_posts ()istfalsch.Sie können "new WP_Query ($ args)" durch "get_posts ($ args)"in Ihrem Codeersetzen undes wirdfunktionieren.

Your conclusion about `get_posts()` is wrong. You can replace `new WP_Query($args)` with `get_posts($args)` in your code and it will work.

OP specifically asked for getting products using a category ID, however, this helped me, so I'll upvote anyhow. Just be aware it doesn't answer the original question

Ändern Sie die Kategorie (Kategorie-Slug-Name)nach ID oder Name oder Slug

 <?php

$args = array( 'post_type' => 'product', 'stock' => 1, 'posts_per_page' => 2,'product_cat' => 'category-slug-name', 'orderby' =>'date','order' => 'ASC' );
  $loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
global $product; 
?>
Within loop we can fetch Product image, title, description, price etc. 

<?phpendwhile;wp_reset_query(); ?>

change category (category-slug-name) by id or name or slug

<?php

$args = array( 'post_type' => 'product', 'stock' => 1, 'posts_per_page' => 2,'product_cat' => 'category-slug-name', 'orderby' =>'date','order' => 'ASC' );
  $loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
global $product; 
?>
Within loop we can fetch Product image, title, description, price etc. 

<?phpendwhile;wp_reset_query(); ?>

Etwas spät,möchte aber die Dinge klären undeine sauberere Antwortgeben. User @benz001gabeine möglichegültige Antwort,sagte aberetwas Falsches: get_postsgibt alle Arten von Post-Typen zurück,standardmäßig posts Post-Typ,genau wie WP_Query. Die wirklichen Unterschiede zwischen denbeiden sind wunderbarerklärt HIER .

------------------------------------------------------------------ Tatsacheist,dass dem OPeinfacheinige Parameterim Array $argsfehlten:

Die Definition des Post-Typs,nach demer sucht:

     'post_type'             => 'product',

     'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'terms' => 26,
            'operator' => 'IN',
        )
    )

Auf diese Weise Ihrenächsten Zeilen

 $products = new WP_Query($args);
var_dump($products);

Zeigt Ihnen diebenötigten Produkte :)

Sebastian Alle anderen zusätzlichen Parameter,die von @benz001 angezeigt werden,sindnatürlichgültig,werdenjedoch vom OPnicht angefordert. Daher habeichbeschlossen,siein dieser Antwort zurückzulassen.

A bit late, but would like to clarify things and provide a cleaner answer. User @benz001 gave a possible valid answer, but said something wrong: get_posts returns any kind of post-types, defaulting to posts post-type, just like WP_Query. The real differences between the two are wonderfully explained HERE.

The fact is, the OP was simply missing some parameters into the $args array:

The definition of the post-type he is searching for:
```
    'post_type'             => 'product',
```

And the modification of the "taxonomy part" of the search query:

    'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'terms' => 26,
            'operator' => 'IN',
        )
    )

This way your next lines

$products = new WP_Query($args);
var_dump($products);

Will show you the needed products :)

All other additional parameters shown by @benz001 are of course valid but not requested by the OP, so I decided to leave them behind in this answer.
