how to create code to import product data in woocommerce code example

Example 1: woocommerce import product programmatically

function myCustomProduct($product_array)
{
    if (!empty($product_array)):
        foreach ($product_array as $product):
            $product_id = wc_get_product_id_by_sku($product['sku']);
            //no product exist with the given SKU so create one
            if (!$product_id):
                $post = [
                    'post_author' => '',
                    'post_content' => $product['content'],
                    'post_status' => "publish",
                    'post_title' => wp_strip_all_tags($product['title']),
                    'post_name' => $product['title'],
                    'post_parent' => '',
                    'post_type' => "product",
                ];
                //Create Post
                $product_id = wp_insert_post($post, $wp_error);

                //set Product Category
                wp_set_object_terms($product_id, $product['product_cat'], 'product_cat');

                //set product type
                wp_set_object_terms($product_id, 'simple', 'product_type');

                update_post_meta($product_id, '_sku', $product['sku']);
                update_post_meta($product_id, 'total_sales', '0');

            //product found
            else:
                $post = [
                    'ID' => $product_id,
                    'post_title' => $product['title'],
                    'post_content' => $product['content'],
                ];
                $post_id = wp_update_post($post, true);
//              if (is_wp_error($post_id))
//              {
//                  $errors = $post_id->get_error_messages();
//                  foreach ($errors as $error)
//                  {
//                      echo $error;
//                  }
//              }
            endif;

            update_post_meta($product_id, '_visibility', 'visible');
            update_post_meta($product_id, '_stock_status', 'instock');
            update_post_meta($product_id, '_product_attributes', array());
            update_post_meta($product_id, '_manage_stock', "yes");
            update_post_meta($product_id, '_backorders', "no");
            update_post_meta($product_id, '_stock', $product['qty']);
            update_post_meta($product_id, '_price', $product['price']);
            //update_post_meta($product_id, '_downloadable', 'yes');
            //update_post_meta($product_id, '_virtual', 'yes');
            //update_post_meta($product_id, '_regular_price', "1");
            //update_post_meta($product_id, '_sale_price', "1");
            //update_post_meta($product_id, '_purchase_note', "");
            //update_post_meta($product_id, '_featured', "no");
            //update_post_meta($product_id, '_weight', "");
            //update_post_meta($product_id, '_length', "");
            //update_post_meta($product_id, '_width', "");
            //update_post_meta($product_id, '_height', "");
            //update_post_meta($product_id, '_sale_price_dates_from', "");
            //update_post_meta($product_id, '_sale_price_dates_to', "");
            //update_post_meta($product_id, '_price', "1");
            //update_post_meta($product_id, '_sold_individually', "");
        endforeach;
    endif;
}

Example 2: export product data from woocommerce mysql

-- If you need to export products from WooCommerce using MySQL then
-- try out the code below:

SELECT 
  p.ID,
  p.post_title,
  `post_content`,
  `post_excerpt`,
  t.name AS product_category,
  t.term_id AS product_id,
  t.slug AS product_slug,
  tt.term_taxonomy_id AS tt_term_taxonomia,
  tr.term_taxonomy_id AS tr_term_taxonomia,
  MAX(CASE WHEN pm1.meta_key = '_stock' then pm1.meta_value ELSE NULL END) as stock,
  MAX(CASE WHEN pm1.meta_key = '_price' then pm1.meta_value ELSE NULL END) as price,
  MAX(CASE WHEN pm1.meta_key = '_regular_price' then pm1.meta_value ELSE NULL END) as regular_price,
  MAX(CASE WHEN pm1.meta_key = '_sale_price' then pm1.meta_value ELSE NULL END) as sale_price,
  MAX(CASE WHEN pm1.meta_key = '_sku' then pm1.meta_value ELSE NULL END) as sku 
FROM wp_posts p 
LEFT JOIN wp_postmeta pm1 ON pm1.post_id = p.ID
LEFT JOIN wp_term_relationships AS tr ON tr.object_id = p.ID
JOIN wp_term_taxonomy AS tt ON tt.taxonomy = 'product_cat' AND tt.term_taxonomy_id = tr.term_taxonomy_id 
JOIN wp_terms AS t ON t.term_id = tt.term_id
WHERE p.post_type in('product', 'product_variation') AND p.post_status = 'publish' AND p.post_content <> ''
GROUP BY p.ID,p.post_title  
ORDER BY `p`.`ID` ASC

-- Now you can export the results to a .csv file :)
-- Happy coding, my homies <3
