Woocommerce customized code sample for WP All Imports

1. Set product stock status based on quantity:

php
function set_stock_status($post_id, $quantity) {
  if ($quantity > 0) {
    update_post_meta($post_id, '_stock_status', 'instock');
  } else {
    update_post_meta($post_id, '_stock_status', 'outofstock'); 
  }
}

This function can be called in the Function Editor to automatically set the stock status based on the imported quantity[2].

2. Generate SKU if not provided:

php
function generate_sku($post_id, $sku) {
  if (empty($sku)) {
    $sku = 'SKU-' . $post_id;
    update_post_meta($post_id, '_sku', $sku);
  }
}

This will create a SKU using the post ID if one is not included in the import file[2].

3. Set product category:

php
function set_product_category($post_id, $category_name) {
  $term = get_term_by('name', $category_name, 'product_cat');
  if ($term) {
    wp_set_object_terms($post_id, $term->term_id, 'product_cat');
  }
}

This allows you to assign a product category by name during import[2].

4. Import variable products:

For importing variable products, you'll need to structure your import file with parent products and variations. WP All Import provides specific documentation on how to format the file and map fields for variable products[1].

5. Custom image handling:

php
function import_product_images($post_id, $image_urls) {
  $image_ids = array();
  $urls = explode(',', $image_urls);
  foreach ($urls as $url) {
    $image_id = media_sideload_image($url, $post_id, '', 'id');
    if (!is_wp_error($image_id)) {
      $image_ids[] = $image_id;
    }
  }
  if (!empty($image_ids)) {
    set_post_thumbnail($post_id, $image_ids[0]);
    update_post_meta($post_id, '_product_image_gallery', implode(',', array_slice($image_ids, 1)));
  }
}

This function allows you to import multiple images, setting the first as the featured image and the rest as the product gallery[2].

Remember to place these code snippets in WP All Import's Function Editor when setting up your import. You can then call these functions within your import template to process the data as needed[2].

For more complex scenarios or specific requirements, you may need to create custom add-ons or use WP All Import's API. The WP All Import documentation provides numerous examples and code snippets for various import scenarios[2].
