WooCommerce: esportare il prodotti in formato JSON

In WooCommerce possiamo esportare i prodotti in formato JSON.

La soluzione è la seguente:

<?php
function my_wc_json_export() {
    $output = array();
    $args = array(
        'post_type' => 'product',
        'numberposts' => -1
    );
    $loop = get_posts( $args );
    if( !empty( $loop ) ) {
        foreach( $loop as $p ) {
            $id = $p->ID;
           $product = new WC_Product( $id );

           if( $product->is_visible() && $product->is_in_stock() && $product->is_purchasable() ) {
            $data = array();
            $img = wp_get_attachment_image_src( $product->get_image_id(), 'thumbnail' );

            $data['id'] = $id;
            $data['sku'] = $product->get_sku();
            $data['name'] = $product->get_name();
            $data['description'] = strip_tags( $product->get_short_description() );
            $data['price'] = $product->get_price();
            $data['image'] = $img[0];
            $data['regular_price'] = $product->get_regular_price();
            $data['sale_price'] = $product->get_sale_price();

            $output[] = $data;
         }

      }
   }
   return wp_send_json( $output );
}
