A hook to prefill PageTable fields with children on edit

Recommended Posts

I use a PageTable field to make edits to children of pages more intuitive

To register the hooks, insert the following Snippet inside your init function in your module (or add it to your init.php file):

/**
 * Initialize the module.
 *
 * ProcessWire calls this when the module is loaded. For 'autoload' modules, this will be called
 * when ProcessWire's API is ready. As a result, this is a good place to attach hooks.
 */
public function init()
{
	// Prefill pageTable field
	$this->wire()->addHookBefore('InputfieldPageTable::render', $this, 'addChildrenToPageTableFieldsHook');
	$this->wire()->addHookBefore('InputfieldPageTableAjax::checkAjax', $this, 'addChildrenToPageTableFieldsHook');
}

Then, add this hook method:

/**
 * Fill pagetable fields with children before editing….
 *
 * @param HookEvent $event
 */
public function addChildrenToPageTableFieldsHook(HookEvent $event)
{
	$field = $event->object;

	// on ajax, the first hook has no fieldname
	if (!$field->name) {
		return;
	}
	
	// get the edited backend page
	$editID = $this->wire('input')->get->int('id');
	if (!$editID && $this->wire('process') instanceof WirePageEditor) {
		$editID = $this->wire('process')->getPage()->id;
	}
	$page = wire('pages')->get($editID);
	
	// disable output formating – without this, the ajax request will not populate the field
	$page->of(false);
	
	// you could also insert a check to only do this with sepcific field names…
	// $page->set($field->name, $page->children('template=DesiredTemplate')); // just specific templates
	$page->set($field->name, $page->children);
}

Now whenever there is a page-table field on your page, it gets populated with the children

Using $page->set() instead of ->add() removes "orphant message"

@bernhard I felt my post is not qualified for a tutorial with »step-by-step instructions on how to do things in ProcessWire« – and since the description for API & Templates contains »answers and support on the API and template development« I thought it would better fit in there. I was actually looking for a hooks / snippet / recipe section in the forum – but that does not exists. I know, there is https://processwire-recipes.com but it just feels to cumbersome to add one 😉

OK i understand 🙂 I just didn't get that it was a snippet and "wasted" time to read your post and try to help where actually no problem existed and thought you might save others from that by naming it more obviously..

      I opened a new wishlist topic on the PW forum for this and in the meantime I ask to the community looking for a reasonable solution.
       
      Using the PageTable field, is there a way to un-restrict the creation of pages under a given parent template page (or as page children if no parent for items is selected)? That is, is there a way to allow the selection of the parent page dynamically / on the fly during page creation via the PageTable field?
    • By LAPS
      I'm using the PW PageTable field extensively and I think an improvement to it could be made regarding the ability to choose the page parent where the page created via PageTable will reside.
      Say you have a PageTable field set like this:
      Edit Field: page_table_field > Details >
      Select one or more templates for items
      > template_one
      > template_two
      > template_three
      Select a parent for items
      > parent_template
      Actually, you can only create pages under the parent_template page (or as page child if no parent for items is selected).
      BTW I am looking for reasons about this limitation.
      What about allowing to choose on the fly where the pages created via PageTable will reside? that is, having the possibility to choose dynamically under which parent page to create the pages?
      Actually, one could overcome to this by creating multiple appropriately set PageTable fields, one PageTable field per PageTable parent for items, but this is unsustainable (?) when you want to create a lot using PageTable…
      By allowing to choose dynamically / on the fly the parent page during page creation via the PageTable field would open up a wider usage of PageTable.
      What do you think about?

      Hello so am trying to make a hook so that all checkbox field is defaul;ty checked when making new page, soo i made hook in init.php and the contents are
      <?php $wire->addHookAfter("Pages::added", function($event) { $page = $event->arguments(0); // check for page template if necessary here $page->checkboxfield('check', 1); }); ?> and what i get
      which is weird because "table" is a repeat field where checkboxfield is nowhere present, but table repeat field and checkboxfield are in the same template, so why does it outputs error like that? any ideas ?

      So I ran into a very strange issue today. I have a template with a pagetable and I went to add an item to it, when I went to select an image (for an image field) the page instantly threw up an error
      "ProcessPageSearchLive: No search specified"
      The page's content also switched to the image attached. This all worked perfectly last week (local mamp box). Has anyone experienced this before, and how did you solve it?

      Hey folks,
      I have a question regarding rendering of template files that are in a subfolder of the template folder.
      How would I for example render these PageTable items, when their template files are inside templates/blocks/:
      <div class="grid"> <?php foreach($page->grid_ext as $item): ?> <div id="pteg_<?= $item->id ?>"> <?php echo $item->render(); ?> </div> <?php endforeach; ?> </div> I tried this, but get an error:
      <?php echo $item->render(wire('config')->paths->templates . '/blocks/'); ?>
