In Woocommerce you can add global product attributes and terms. So for instance:

Size (attribute)
small (term)
medium (term)
large (term)

This is product independent. You can then select from the pre defined attributes on a product.

I need to get all of the terms in an attribute with php. So select the attribute required, eg size, and then return an array including [small,medium,large].

Seems simple enough but I can't find any help on doing this.

Slightly confusing, especially when looking through the WooCommerce Docs since there is absolutely no mention of getting a list of the terms/attributes.

The Attributes are saved as a custom taxonomy, and the terms are taxonomy terms. That means you can use native Wordpress functions: Wordpress get_terms() Function Reference

By clicking on an attribute in WooCommerce, you can look in the URL and you can see they are all prepended with 'pa_'

This is likely what you need:

$terms = get_terms("pa_size");
foreach ( $terms as $term ) {
echo "<option>" . $term->name . "</option>";
}

I wanted to be able to get all the different attributes from the backend that were set, and get them in an array for me to work with, I took some code from the class-wc-admin-attributes.php file and modified it for my needs:

<?php
$attribute_taxonomies = wc_get_attribute_taxonomies();
$taxonomy_terms = array();
if ($attribute_taxonomies) : foreach ($attribute_taxonomies as $tax) : if (taxonomy_exists(wc_attribute_taxonomy_name($tax->attribute_name))) : $taxonomy_terms[$tax->attribute_name] = get_terms(wc_attribute_taxonomy_name($tax->attribute_name), 'orderby=name&hide_empty=0'); endif; endforeach;
endif;
var_dump($taxonomy_terms);
exit;

This will loop through all the attribute taxonomies, retrieve the terms for each, leaving you with an array of term objects to work with for each taxonomy.

Since 4.5.0, taxonomies should be passed via the ‘taxonomy’ argument in the $args array:

$terms = get_terms( array( 'taxonomy' => 'pa_taxonyname', 'hide_empty' => false,
) );

For example, if the taxonomy slug is 'date', so the taxonomy will be 'pa_date'. You can also mouse over the attribute name and see the taxonomy name at the bottom of the browser.

I hope it helps!

I use this:

echo '<h1>variations</h1>';
mario( $product->get_available_variations());
echo '<h1>Atributos</h1>';
mario($product->get_attributes());
echo '<h1>Poste Terms</h1>';
mario(wp_get_post_terms( $post->ID, 'pa_color'));
function mario($texto){ echo '<pre>';var_dump($texto);echo '</pre>';
};

Really with: "wp_get_post_terms( $post->ID, 'pa_color')" i search only one term, but the idea is to loop for the key ['name'] that return that function.

Get all attributes with attribute terms in woocommerce.

$attributes = wc_get_attribute_taxonomies();
foreach ($attributes as $attribute) { $attribute->attribute_terms = get_terms(array( 'taxonomy' => 'pa_'.$attribute->attribute_name, 'hide_empty' => false, ));
}
