How programmatically create product category and add thumbnail in woocommerce?

patrick

I am creating product-(sub)categories in WordPress installation. I am not able to add the thumbnail image to the specific category.
I need to fill seek an attachment ID in wp_admin, I uploaded the image as an attachment, without connecting it to a particular post. I then created my category, and tried the field namesproduct_cat_thumbnail_id and thumbnail_id inside the wp_insert_term() function and fill them with the attachment id. As the wp-admin function does, except that wp-admin fills it with JavaScript after uploading, then saves it when the category is generated.
Please tell me what I am missing

First, collect the category and the related data such as name, thumbnail, description, slug, parent id, etc.
Now use the foreach loop to go through all the categories. Use fetch_media() to get the thumbnail id and wp_insert_term() function to create the product category.

Update the thumbnail id with the category id with the help of update_term_meta() function.

$cats = array(
    array('thumb' => 'images/uploads/cat09.png','name' => 'Cat 9','description' => 'Cat 9 description','slug' => 'cat-9','parent' => 8),
    array('thumb' => 'images/uploads/cat10.png','name' => 'Cat 10','description' => 'Cat 10 description','slug' => 'cat-10','parent' => 8),
    array('thumb' => 'images/uploads/cat11.png','name' => 'Cat 11','description' => 'Cat 11 description','slug' => 'cat-11','parent' => 8),
);

foreach($cats as $data) {
    $thumb_id = fetch_media($data['thumb']);
    $cid = wp_insert_term(
        $data['name'], // the term 
        'product_cat', // the taxonomy
        array(
            'description'=> $data['description'],
            'slug' => $data['slug'],
            'parent' => $data['parent']
        )
    );

    if(!is_wp_error($cid)){
        $cat_id = isset( $cid['term_id'] ) ? $cid['term_id'] : 0;
        update_term_meta( $cat_id, 'thumbnail_id', absint( $thumb_id ) );
    }
}
