TYPO3 Extbase: How to render the pagetree from my model? - sitemap

Question

I want to create some kind of sitemap in extbase/fluid (based on the pagetree). I have loaded the pages table into a model:
config.tx_extbase.persistence.classes.Tx_MyExt_Domain_Model_Page.mapping.tableName = pages
I have created a controller and repository, but get stuck on the part wich can load the subpages as relation into my model.
For example:
$page = $this->pageRepository->findByPid($rootPid);
Returns my rootpage. But how can I extend my model that I can use $page->getSubpages() or $page->getNestedPages()?
Do I have to create some kind of query inside my model? Or do I have to resolve this with existing functions (like the object storage) and how?
I tried a lot of things but can simply figure out how this should work.

Answer 1

you have to overwrite your findByPid repository-method and add
public function findByPid($pid) {
$querySettings = $this->objectManager->create('Tx_Extbase_Persistence_Typo3QuerySettings');
$querySettings->setRespectStoragePage(FALSE);
$this->setDefaultQuerySettings($querySettings);
$query = $this->createQuery();
$query->matching($query->equals('pid', $pid));
$pages = $query->execute();
return $pages;
}
to get all pages. Than you can write your own getSubpages-method like
function getSubpages($currentPid) {
$subpages = $this->pagesRepository->findByPid($currentPid);
if (count($subpages) > 0) {
$i = 0;
foreach($subpages as $subpage) {
$subpageUid = $subpage->getUid();
$subpageArray[$i]['page'] = $subpage;
$subpageArray[$i]['subpages'] = $this->getSubpages($subpageUid);
$i++;
}
} else {
$subpageArray = Array();
}
return $subpageArray;
}
i didn't test this method, but it looks like this to get alle subpages.

i wonder that i could´t find a typo3 method that return the complete Page-Tree :( So i write a little function (you can use in an extbase extension), for sure not the best or fastes way, but easy to extend or customize ;)
first you need an instance of the PageRepository
$this->t3pageRepository = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Frontend\\Page\\PageRepository');
this->t3pageRepository->init();
make the init, to set some basic confs, like "WHERE deletet = 0 AND hidden = 0..."
then with this function you get an array with the page data and subpages in. I implement yust up to three levels:
function getPageTree($pid,$deep=2){
$fields = '*';
$sortField = 'sorting';
$pages = $this->t3pageRepository->getMenu($pid,$fields,$sortField);
if($deep>=1){
foreach($pages as &$page) {
$subPages1 = $this->t3pageRepository->getMenu($page['uid'],$fields,$sortField);
if(count($subPages1)>0){
if($deep>=2){
foreach($subPages1 as &$subPage1){
$subPages2 = $this->t3pageRepository->getMenu($subPage1['uid'],$fields,$sortField);
if(count($subPages2>0)){
$subPage1['subpages'] = $subPages2;
}
}
}
$page['subpages'] = $subPages1;
}
}
}
return $pages;
}
