Créer par programmation un Thème la variation du produit avec de nouvelles valeurs d'attribut

Expansion sur LoicTheAztec réponse, vous pouvez vérifier si l'attribut combinaison existe avec la modification suivante à son code.

function create_update_product_variation( $product_id, $variation_data ){
if(isset($variation_data['variation_id'])) {
$variation_id = $variation_data['variation_id'];
} else {
//if the variation doesn't exist then create it
//Get the Variable product object (parent)
$product = wc_get_product($product_id);
$variation_post = array(
'post_title'  => $product->get_title(),
'post_name'   => 'product-'.$product_id.'-variation',
'post_status' => 'publish',
'post_parent' => $product_id,
'post_type'   => 'product_variation',
'guid'        => $product->get_permalink()
);
//Creating the product variation
$variation_id = wp_insert_post( $variation_post );
}
//...
}

Exemple d'utilisation

//The variation data
$variation_data =  array(
'attributes' => array(
'size'  => 'M',
'color' => 'Green',
),
'sku'           => '',
'regular_price' => '22.00',
'sale_price'    => '1',
'stock_qty'     => 1,
);
//check if variation exists
$meta_query = array();
foreach ($variation_data['attributes'] as $key => $value) {
$meta_query[] = array(
'key' => 'attribute_pa_' . $key,
'value' => $value
);
}
$variation_post = get_posts(array(
'post_type' => 'product_variation',
'numberposts' => 1,
'post_parent'   => $parent_id,
'meta_query' =>  $meta_query
));
if($variation_post) {
$variation_data['variation_id'] = $variation_post[0]->ID;
}
create_update_product_variation( $product_id, $variation_data );

Je vais juste jeter ce là-bas, puisque je ne pouvais pas obtenir les exemples ci-dessus travail. Ne me demandez pas pourquoi d'autres personnes semblent avoir du succès. Donc, j'ai pris l'approche minimaliste et essayé de comprendre l'essentiel pour un produit attribut + variation (en créant manuellement dans wp et en regardant la db) et est venu avec cette.

$article_name = 'Test';
$post_id = wp_insert_post( array(
'post_author' => 1,
'post_title' => $article_name,
'post_content' => 'Lorem ipsum',
'post_status' => 'publish',
'post_type' => "product",
) );
wp_set_object_terms( $post_id, 'variable', 'product_type' );
$attr_label = 'Test attribute';
$attr_slug = sanitize_title($attr_label);
$attributes_array[$attr_slug] = array(
'name' => $attr_label,
'value' => 'alternative 1 | alternative 2',
'is_visible' => '1',
'is_variation' => '1',
'is_taxonomy' => '0' //for some reason, this is really important       
);
update_post_meta( $post_id, '_product_attributes', $attributes_array );
$parent_id = $post_id;
$variation = array(
'post_title'   => $article_name . ' (variation)',
'post_content' => '',
'post_status'  => 'publish',
'post_parent'  => $parent_id,
'post_type'    => 'product_variation'
);
$variation_id = wp_insert_post( $variation );
update_post_meta( $variation_id, '_regular_price', 2 );
update_post_meta( $variation_id, '_price', 2 );
update_post_meta( $variation_id, '_stock_qty', 10 );
update_post_meta( $variation_id, 'attribute_' . $attr_slug, 'alternative 1' );
WC_Product_Variable::sync( $parent_id );
$variation_id = wp_insert_post( $variation );
update_post_meta( $variation_id, '_regular_price', 2 );
update_post_meta( $variation_id, '_price', 2 );
update_post_meta( $variation_id, '_stock_qty', 10 );
update_post_meta( $variation_id, 'attribute_' . $attr_slug, 'alternative 2' );
WC_Product_Variable::sync( $parent_id );

Ce n'est pas en utilisant les attributs d'un produit, mais l'article spécifique. Espérons que cela aide quelqu'un que j'étais prêt à m'arracher les cheveux, avant que j'ai eu de travail.

il fonctionne mais a besoin d'un peu de corrections (2 virgules dans les fonctions de tableau), j'ai fait de modifier une partie du code à mes besoins.

(travail sur wp 4.9 | wc 3.5)

D'abord les produits ont l'attribut déjà créé et associé, mon taxonomie est "pa_r" nom convivial "R"
backend attribut associeated img

la fonction avec la correction

function create_product_variation( $product_id, $variation_data ){
//Get the Variable product object (parent)
$product = wc_get_product($product_id);
$variation_post = array(
'post_title'  => $product->get_title(),
'post_name'   => 'product-'.$product_id.'-variation',
'post_status' => 'publish',
'post_parent' => $product_id,
'post_type'   => 'product_variation',
'guid'        => $product->get_permalink()
);
//Creating the product variation
$variation_id = wp_insert_post( $variation_post );
//Get an instance of the WC_Product_Variation object
$variation = new WC_Product_Variation( $variation_id );
//Iterating through the variations attributes
foreach ($variation_data['attributes'] as $attribute => $term_name )
{
$taxonomy = 'pa_'.$attribute; //The attribute taxonomy
//If taxonomy doesn't exists we create it (Thanks to Carl F. Corneil)
if( ! taxonomy_exists( $taxonomy ) ){
register_taxonomy(
$taxonomy,
'product_variation',
array(
'hierarchical' => false,
'label' => ucfirst( $taxonomy ),
'query_var' => true,
'rewrite' => array( 'slug' => '$taxonomy') //The base slug
)
);
}
//Check if the Term name exist and if not we create it.
if( ! term_exists( $term_name, $taxonomy ) )
wp_insert_term( $term_name, $taxonomy ); //Create the term
$term_slug = get_term_by('name', $term_name, $taxonomy )->slug; //Get the term slug
//Get the post Terms names from the parent variable product.
$post_term_names =  wp_get_post_terms( $product_id, $taxonomy, array('fields' => 'names') );
//Check if the post term exist and if not we set it in the parent variable product.
if( ! in_array( $term_name, $post_term_names ) )
wp_set_post_terms( $product_id, $term_name, $taxonomy, true );
//Set/save the attribute data in the product variation
update_post_meta( $variation_id, 'attribute_'.$taxonomy, $term_slug );
}
## Set/save all other data
//SKU
if( ! empty( $variation_data['sku'] ) )
$variation->set_sku( $variation_data['sku'] );
//Prices
if( empty( $variation_data['sale_price'] ) ){
$variation->set_price( $variation_data['regular_price'] );
} else {
$variation->set_price( $variation_data['sale_price'] );
$variation->set_sale_price( $variation_data['sale_price'] );
}
$variation->set_regular_price( $variation_data['regular_price'] );
//Stock
if( ! empty($variation_data['stock_qty']) ){
$variation->set_stock_quantity( $variation_data['stock_qty'] );
$variation->set_manage_stock(true);
$variation->set_stock_status('');
} else {
$variation->set_manage_stock(false);
}
$variation->set_weight(''); //weight (reseting)
$variation->save(); //Save the data
}

J'ai fait un tableau avec les données dont j'ai besoin dans les variations de la [id_post, attribut, sku, regular_price, stock]

$hijos = array(
[9623,'265/70 R16','NE-CT-CO-USA-016-005','0',53],
[9624,'235/65 R17','NE-AU-CO-EUR-017-050','189000',56]
);

et le foreach pour créer dynamiquement toutes les variations de mes produits

foreach ($hijos as $vari) {
//The variation data
$variation_data =  array(
'attributes' => array(
'r'  => $vari[1],
),
'sku'           => $vari[2],
'regular_price' => str_replace('.', '', $vari[3]),
'stock_qty'     => $vari[4]
);
//var_dump($variation_data);
create_product_variation( $vari[0], $variation_data );
}
