Kirby Modules: print sub-subpages (eg grandChildren)

Kirby 2 Solved ✅
1

Hi,

using Kirby Modules I have nested a module inside a module (I need that level of indentation for a survey).

The page is correctly created in the blueprint.

When I tried to adjust the module-name.html.php to fit this level of depth, by using grandChildren()

<li>
    <?php foreach($module->grandChildren()->builder()->toStructure() as $section): ?>
      <?php snippet('sections/' . $section->_fieldset(), array('data' => $section)) ?>
    <?php endforeach ?>
</li>

I get an error message saying the object is null.

  1. Is there a better way to nest modules within modules?
  2. How can I print all pages and sub-pages part of a module?

If $module is the module page, and the nested module is a subpage of that module, shouldn’t it be child of $module instead of a grandchild?

Yes, I first tried that but I got the same error.

I also tried to test it with only one of the two modules who has a subpage module, but same problem

Call to a member function toStructure() on null

Oh, having a fresh look often helps. In fact, it’s not that surprising that it does not work: you are trying to get the builder field from a collection; you have to loop through the collection first and then call the builder field on each page, of course:

<?php foreach($module->children() as $child): ?>
  <?php $builder = $child->builder()->toStructure(): ?>
   <?php foreach($builder as $section): ?>
      <?php snippet('sections/' . $section->_fieldset(), array('data' => $section)) ?>
    <?php endforeach ?>
  <?php endforeach ?>

Right! Thanks.

This approach works, I actually replaced ->children() with ->grandChildren() and it picks up the subpage correctly.

<li>
  <fieldset class="bd--a_red pd--v_1" id="<?php echo $module->num() ?>">
    <?php foreach($module->builder()->toStructure() as $section): ?>
      <?php snippet('sections/' . $section->_fieldset(), array('data' => $section)) ?>
    <?php endforeach ?>

    <?php foreach($module->index() as $child): ?>
      <?php $builder = $child->builder()->toStructure(); ?>
      <?php foreach($builder as $section): ?>
        <?php snippet('sections/' . $section->_fieldset(), array('data' => $section)) ?>
      <?php endforeach ?>
  <?php endforeach ?>
  </fieldset>
</li>
