Martinus Posted August 22, 2022 Posted August 22, 2022 I have this selector: $items = $pages->find("parent=/categories/, sort=title"); foreach($items as $item) { echo <h4><a href=''>" . $item->title . "</a></h4> <ul>" . $item->children->each( "<li><a href='{url}'>{title}</a></li>" ) . "</ul> But, do I need to check with if($item->hasChildren ? Because the IF does not work.
3fingers Posted August 22, 2022 Posted August 22, 2022 Check this : https://processwire.com/api/ref/page/children/ // Render navigation for all child pages below this one foreach($page->children() as $child) { echo "<li><a href='$child->url'>$child->title</a></li>"; } So in your case: $children = $pages->find("parent=/categories/, sort=title")->children(); foreach($children as $child) { // ... manipulate $child here } 1
Martinus Posted August 22, 2022 Author Posted August 22, 2022 I understand if I want to find children of the page I am on I can do that. The API says: // Render navigation for all child pages below this one But in my case I am on one page and finding category pages (elsewhere) - then I display them one by one as $item: foreach($items as $item) { So now I have parent $item-1 and need it's children; I have parent $item-2 and need it's children; etc. $item->children->each( "<li><a href='{url}'>{title}</a></li>" ) works fine.... I think.
