Sample code to import data in WooCommerce

php
<?php
// Make sure WooCommerce is active
if (!function_exists('WC')) {
    return;
}

// File path to your CSV
$file = WP_PLUGIN_DIR . '/woocommerce/sample-data/sample_products.csv';

// Get the WC_Product_CSV_Importer class
require_once WC_ABSPATH . 'includes/import/class-wc-product-csv-importer.php';

// Set up import parameters
$params = array(
    'parse'               => true,
    'prevent_timeouts'    => false,
    'mapping'             => array(
        'from' => array('name', 'description', 'short_description', 'price', 'regular_price', 'sale_price', 'stock_quantity'),
        'to'   => array('name', 'description', 'short_description', 'price', 'regular_price', 'sale_price', 'stock_quantity')
    ),
    'update_existing'     => false,
    'delimiter'           => ',',
);

// Create the importer object
$importer = new WC_Product_CSV_Importer($file, $params);

// Run the import
$results = $importer->import();

// Check for errors
if (is_wp_error($results)) {
    echo "Import failed: " . $results->get_error_message();
} else {
    echo "Import successful. " . count($results) . " products imported.";
}

This code does the following:

1. It checks if WooCommerce is active[1].

2. It specifies the path to the CSV file containing product data. In this example, it uses the sample data provided by WooCommerce[1].

3. It loads the WC_Product_CSV_Importer class[2].

4. It sets up import parameters, including mapping CSV columns to WooCommerce product fields[2][4].

5. It creates an importer object and runs the import[2][4].

6. Finally, it checks for errors and reports the results[4].

To use this code:

1. Make sure you have a valid CSV file with product data.
2. Adjust the `$file` path to point to your CSV file.
3. Modify the `mapping` array if your CSV has different column names.
4. Run this code in a PHP file or as part of a WordPress plugin.

Remember to back up your database before running any import scripts. Also, for large datasets, you may need to adjust PHP execution time and memory limits[4].

This is a basic example. For more complex imports or specific needs, you might need to extend this code or use WooCommerce hooks to customize the import process further[2][4].
