How to sort by number

Question

I have to sort my results by number:

<ul>
 <?php $productTerms = get_terms('prezzoceste', array('hide_empty' => 0, 'orderby' => 'ASC', 'meta_type' => 'NUMERIC', ));
foreach($productTerms as $productTerm) :
?>
<li>
<i class="fas fa-circle"></i>
<a href="<?php echo get_term_link( $productTerm->slug, $productTerm->taxonomy ); ?>"><?php echo $productTerm->name; ?> <span>(<?php echo $productTerm->count; ?>)</span></a>
</li>
<?php endforeach; ?>
</ul>

Answer 1

You are using pre 4.5.0 code which will eventually be depricated. Try this.

$productTerms = get_terms( array(
    'taxonomy' => 'prezzoceste',
    'hide_empty' => false,
    'orderby' => 'ASC',
    'meta_key' => '_price', //The price Meta Key
    'orderby' => 'meta_value_num',
) );
