In Woocommerce, I successfully added a custom field for product variations within the backend. Saving its input data and displaying it within the add-to-cart/variation.php
works as well.
But what about displaying the value of this field within the cart.php
?
I only found solutions of this for regular product items but not for product variations. Here's what I have so far within my functions.php file:
//Display Fields in admin on product edit screen
add_action( 'woocommerce_product_after_variable_attributes', 'woo_variable_fields', 10, 3 );
//Save variation fields values
add_action( 'woocommerce_save_product_variation', 'save_variation_fields', 10, 2 );
// Create new fields for variations
function woo_variable_fields( $loop, $variation_data, $variation ) {
echo '<div class="variation-custom-fields">';
// Text Field
woocommerce_wp_text_input(
array(
'id' => '_text_field['. $loop .']',
'label' => __( 'additional fees (e.g. monthly fee)', 'woocommerce' ),
'placeholder' => '',
//'desc_tip' => true,
'wrapper_class' => 'form-row form-row-first',
//'description' => __( 'Enter the custom value here.', 'woocommerce' ),
'value' => get_post_meta($variation->ID, '_text_field', true)
)
);
echo "</div>";
}
/** Save new fields for variations */
function save_variation_fields( $variation_id, $i) {
// Text Field
$text_field = stripslashes( $_POST['_text_field'][$i] );
update_post_meta( $variation_id, '_text_field', esc_attr( $text_field ) );
}
// Custom Product Variation
add_filter( 'woocommerce_available_variation', 'custom_load_variation_settings_products_fields' );
function custom_load_variation_settings_products_fields( $variations ) {
$variations['variation_custom_field'] = get_post_meta( $variations[ 'variation_id' ], '_text_field', true );
return $variations;
}
