Message:

I have my own menu structure in the template. The code below works fine. Here I get the parent category and all the subcategories of that parent category. The problem is that now I need to output another level of nesting.

<?php

$taxonomies = get_terms(array(

    'taxonomy' => 'product_cat',

    'hide_empty' => true

));



if (!empty($taxonomies)) :

    foreach ($taxonomies as $category) {

        if ($category->parent == 0) {

            $output .= '<div class="menu_item">';

            if ($category->parent == 0 && get_term_children($category->term_id, 'product_cat')) {

                if ($category->parent == 0) {

                    $output .= '<div class="parent_item"><a href="' . get_term_link($category) . '">' . $category->name . '</a></div>';

                }

                $output .= '<div class="sub_menu">';

                foreach ($taxonomies as $subcategory) {

                    if ($subcategory->parent == $category->term_id) {

                        $output .= '<div class="sub_item"><a href="' . get_term_link($subcategory) . '">' . $subcategory->name . '</a></div>';

                    }

                }

                $output .= '</div>';

            }

            $output .= '</div>';

        }

    }

    echo $output;

endif;

?>

And that's where I broke down). I can't figure out how to get another level of nesting). I get the following result:

<div class="menu_item">



    <div class="parent_item">

        <a href="#">Parent Menu Item</a>

    </div>



    <div class="sub_menu">

        <div class="sub_item">

            <a href="#">Sub Menu Item</a>

        </div>

        

        <div class="sub_item">

            <a href="#">Sub Menu Item</a>

        </div>

    </div>



</div>

My Answer:
To add another level of nesting for subcategories of subcategories, you can modify the code as follows:

php

$taxonomies = get_terms(array(

    'taxonomy' => 'product_cat',

    'hide_empty' => true

));



if (!empty($taxonomies)) :

    foreach ($taxonomies as $category) {

        if ($category->parent == 0) {

            $output .= '';

            if ($category->parent == 0 && get_term_children($category->term_id, 'product_cat')) {

                $output .= '' . $category->name . '
';

                $output .= '';

                foreach ($taxonomies as $subcategory) {

                    if ($subcategory->parent == $category->term_id) {

                        $output .= '' . $subcategory->name . '
';

                        $output .= '';

                        foreach ($taxonomies as $subsubcategory) {

                            if ($subsubcategory->parent == $subcategory->term_id) {

                                $output .= '' . $subsubcategory->name . '
';

                            }

                        }

                        $output .= '
';

                    }

                }

                $output .= '
';

            }

            $output .= '
';

        }

    }

    echo $output;

endif;

This code will now display the parent category, its subcategories, and the subcategories of those subcategories in a nested structure. You can continue this nesting pattern for as many levels as needed.
