Get children category of a taxonomy by parent id

Question

I have a custom post type "project" with a taxonomy "taxoproject"and I have a template page "template-project.php" with a query loop to display my post.

In this loop I need to display each category associated with the post.

This is my code :

<ul>
   <?php
     $terms = get_the_terms($post->ID, 'taxoproject');
     foreach($terms as $term) { ?>

         <li>
            <?php echo $term->name; ?>
         </li>

     <?php }
   ?>
</ul>

My code works perfectly with one exception, I wish to display only the children of a specific parent of this taxonomy (id 76) and I do not know how to proceed.

Thanks for your help

Answer 1

I found the solution to my problem :

<ul>
    <?php
        $taxonomy = 'taxoproject'; // Taxonomy slug.
        $terms = get_the_terms( $post->ID, $taxonomy );

        $children = '';

        foreach ( $terms as $term ) {
            if( $term -> parent == 76 ) { // Parent ID 
                $children = $term->name; ?>

                <li><?php echo $children; ?></li>

            <?php } 
        }
    ?>
</ul>

Thank you all for the help !
