PHP and Concrete 5 count subpages - php

Question

Making mobile site with Concrete5 and using page list block with custom template. I'm trying to count sub pages using PHP.
<?php foreach ($pages as $page):
// Prepare data for each page being listed...
$title = $th->entities($page->getCollectionName());
$url = $nh->getLinkToCollection($page);
$target = ($page->getCollectionPointerExternalLink() != '' && $page->openCollectionPointerExternalLinkInNewWindow()) ? '_blank' : $page->getAttribute('nav_target');
$target = empty($target) ? '_self' : $target;
$description = $page->getCollectionDescription();
$description = $controller->truncateSummaries ? $th->shorten($description, $controller->truncateChars) : $description;
$description = $th->entities($description);
$mies = 0;
?>
<li class="ui-btn ui-btn-icon-right ui-li-has-arrow ui-li ui-btn-up-c" data-theme="c"><div aria-hidden="true" class="ui-btn-inner ui-li"><div class="ui-btn-text"><a target="<?php echo $target ?>" class="ui-link-inherit" href="<?php echo $url ?>">
<h2 class="ui-li-heading"><?php echo $title ?></h2>
<p class="ui-li-desc"><?php echo $description ?></p>
</a>
</div><span class="ui-icon ui-icon-arrow-r ui-icon-shadow"></span><span class="ul-li-count ui-btn-corner-all ul-count-second"><?php echo count($mies) ?></span></div></li>
<?php endforeach; ?>
So, probably need to use Count function(or length?), I don't know. If I am editing wrong place please advice if you have any experience in Concrete5 cms.

Answer 1

If you want to show the corresponding page number in the span element in your code:
<span class="ul-li-count ui-btn-corner-all ul-count-second"><?php echo $mies; ?></span>
If you want to show the remaining sub-pages, then in the html code snippet above just replace $mies with count($pages) - $mies like:
<span class="ul-li-count ui-btn-corner-all ul-count-second"><?php echo count($pages) -$mies; ?></span>
You would first have to initialise $mies before you start the forloop so it should be something of the form:
<?php
$mies = 0;
foreach ($pages as $page):
//Rest of your code and increment $mies with every iteration
$mies ++; //This ensures that you are counting the corresponding pages
?>
If you want to get the count of total number of sub-pages, you just have to echo out $mies outside the for block may be like:
<?php
endforeach;
echo $mies; //Shows you the total number of pages processed inside the for loop.
//or Just find the length of pages array
echo count($pages);
?>
As far as getting the length of array is concerned you could use count or sizeof. I stumbled upon a SO question about using count or sizeof method for finding the length of an array.
This should get you started in the right direction.

Answer 2

You need the parent ID;
$parentId = Page::getCollectionParentId();
Note that Page::getCollectionParentId() gets the current page's parent ID,so you may want to try;
$parentId = $page->getCollectionParentID();
Then create a new PageList to filter with and filter by the parentId;
Loader::model('page_list');
$pl = new PageList();
$pl->filter(false, '(p1.cParentID IN ' . $parentId . ')');
// Get the total
var_dump($pl->getTotal());
This is untested but the theory makes sense.

Answer 3

This is likely a bit simpler.
$pl->getTotal()
$pl is the PageList object that is set in the controller.
Also, these days you can just use the h() method instead of writing out $th->entities()
Edit: I should clarify that you don't need to do a $pl = new PageList() because $pl is already set to the PageList object in the controller and passed to the view.
