In WooCommerce, I have an attribute called License Type. This attribute has 2 terms:
Single Site LicenseMulti Site License
With the above, I’m trying to create a custom select dropdown, where the option contains the variation ID.
For example, my product has both of those variations assigned. For that product:
Single Site Licensehas an ID of 210Multi Site Licensehas an ID of 211
So, I’m looking for my output to look something like this:
<select name="pa_license-type" id="pa_license-type">
<option value="single-site-license" data-variation-id="210">Single Site License</option>
<option value="multi-site-license" data-variation-id="211">Multi Site License</option>
</select>
To make this dynamic, for each product, I’ve attempted the following:
if ($product->is_type('variable')) :
$product_id = $product->get_id();
$available_variations = $product->get_children();
$attributes = $product->get_variation_attributes();
foreach ($attributes as $attribute_name => $options) :
$taxonomy = str_replace('attribute_', '', $attribute_name);
$terms = get_terms(array(
'taxonomy' => $taxonomy,
'hide_empty' => false,
));
if (!is_wp_error($terms) && !empty($terms)) :
$attribute_label = wc_attribute_label($taxonomy);
echo '<label for="' . esc_attr($taxonomy) . '">' . esc_html($attribute_label) . '</label>';
echo '<select name="' . esc_attr($taxonomy) . '" id="' . esc_attr($taxonomy) . '">';
$variation_ids_map = array();
foreach ($terms as $term) :
$term_slug = $term->slug;
$current_variation_id = '';
foreach ($available_variations as $variation_id_candidate) :
$variation = wc_get_product($variation_id_candidate);
if ($variation && has_term($term_slug, $taxonomy, $variation->get_id())) :
$current_variation_id = $variation->get_id();
break;
endif;
endforeach;
$variation_ids_map[$term_slug] = $current_variation_id;
echo '<option value="' . esc_attr($term_slug) . '" data-variation-id="' . esc_attr($current_variation_id) . '">' . esc_html($term->name) . '</option>';
endforeach;
echo '</select>';
endif;
endforeach;
endif;
?>
But that yields:
<select name="pa_license-type" id="pa_license-type">
<option value="single-site-license" data-variation-id="">Single Site License</option>
<option value="multi-site-license" data-variation-id="">Multi Site License</option>
</select>
Any ideas on where I’m going wrong?
Images of backend if reference needed:
There are some mistakes and complications. Try the following simplified code version:
global $product; // If needed
if ( $product->is_type('variable') ) {
$taxonomy = 'pa_license-type'; // Targeted global product attribute taxonomy
$terms = array(); // Initializing
// Loop through available variations
foreach ( $product->get_children() as $variation_id ) {
$variation = wc_get_product( $variation_id ); // Get the product variation object
if ( $variation && $variation->exists() && $variation->variation_is_visible() ) {
if ( $term = get_term_by('name', esc_html( $variation->get_attribute($taxonomy) ), $taxonomy) ) {
$terms[$variation->get_id()] = $term;
}
}
}
if ( count($terms) > 0 ) {
printf('<label for="%s">%s</label><select name="%s" id="%s">',
esc_attr($taxonomy), wc_attribute_label($taxonomy), esc_attr($taxonomy), esc_attr($taxonomy) );
foreach ( $terms as $variation_id => $term ) {
printf('<option value="%s" data-variation-id="%d">%s</option>', esc_attr($term->slug), $variation_id, esc_html($term->name) );
}
echo '</select>';
}
}
It should work.
