WooCommerce import Tags custom code

1. Create a custom taxonomy for the tags in your theme's functions.php file or a custom plugin:

php
function create_custom_taxonomy() {
    register_taxonomy(
        'product_tags',
        'product',
        array(
            'label' => __( 'Product Tags' ),
            'rewrite' => array( 'slug' => 'product-tags' ),
            'hierarchical' => false,
        )
    );
}
add_action( 'init', 'create_custom_taxonomy' );

This creates a custom taxonomy called "Product Tags" that can be assigned to products[1].

2. Extend the WooCommerce product import functionality to support the custom taxonomy:

php
function woocommerce_add_custom_taxonomy( $product, $data ) {
    $tags = explode( ',', $data['product_tags'] );
    $tags = array_map( 'trim', $tags );
    wp_set_object_terms( $product->get_id(), $tags, 'product_tags' );
    return $product;
}
add_filter( 'woocommerce_product_import_inserted_product_object', 'woocommerce_add_custom_taxonomy', 10, 2 );

This code splits the CSV column "product_tags" by commas, trims the tags, and assigns them to the product using the custom taxonomy[1].

3. In your CSV file, include a column for the custom tags, for example:

ID,Name,product_tags
1,Product 1,"tag1, tag2, tag3"
2,Product 2,"tag2, tag4"

4. Import the CSV file using the WooCommerce product importer. The custom tags will be assigned to the products[1].

5. To display the custom tags on the single product page, you can use the `the_terms()` function:

php
<?php 
$product_tags = get_the_terms( $product->get_id(), 'product_tags' );
if ( $product_tags ) {
    echo '<div class="product-tags">';
    echo '<h3>Product Tags:</h3>';
    echo '<ul>';
    foreach ( $product_tags as $tag ) {
        echo '<li>' . esc_html( $tag->name ) . '</li>';
    }
    echo '</ul>';
    echo '</div>';
}
?>

This code retrieves the custom tags assigned to the product and displays them in an unordered list[4].

By following these steps, you can import custom product tags to WooCommerce using a CSV file and custom code. The key is extending the product importer to support the custom taxonomy and including the tags in the CSV file.
