How to show number of sub categories within a category

[CONetWebDesign]

The code below is what I found on the forum to show the amount of PRODUCTS per category but is there a way to show the amount of sub categories within a category?

 

Here is the solution tested and working in Prestashop 1.4.7.

 

You can follow these instructions below or just download the already modified files from the zip file attached here.

 

Hope this helps.

 

Open "blockcategories.php" in the folder /modules/blockcategories and find this lines of code (should start at line 140 or so):

public function getTree($resultParents, $resultIds, $maxDepth, $id_category = 1, $currentDepth = 0)
{
 global $link;
 $children = array();
 if (isset($resultParents[$id_category]) AND sizeof($resultParents[$id_category]) AND ($maxDepth == 0 OR $currentDepth < $maxDepth))
  foreach ($resultParents[$id_category] as $subcat)
$children[] = $this->getTree($resultParents, $resultIds, $maxDepth, $subcat['id_category'], $currentDepth + 1);
 if (!isset($resultIds[$id_category]))
  return false;

 return array('id' => $id_category, 'link' => $link->getCategoryLink($id_category, $resultIds[$id_category]['link_rewrite']),
  'name' => $resultIds[$id_category]['name'], 'desc'=> $resultIds[$id_category]['description'],
  'children' => $children);
}

 

And change them to this:

public function getTree($resultParents, $resultIds, $maxDepth, $id_category = 1, $currentDepth = 0)
{
 global $link;
 $children = array();
 if (isset($resultParents[$id_category]) AND sizeof($resultParents[$id_category]) AND ($maxDepth == 0 OR $currentDepth < $maxDepth))
  foreach ($resultParents[$id_category] as $subcat)
$children[] = $this->getTree($resultParents, $resultIds, $maxDepth, $subcat['id_category'], $currentDepth + 1);
 if (!isset($resultIds[$id_category]))
  return false;

$ProductsCount = 0;
$ProductsCount = (int)Db::getInstance()->getValue('SELECT COUNT(*) FROM '._DB_PREFIX_.'category_product WHERE id_category = '. $id_category);

 return array('id' => $id_category, 'link' => $link->getCategoryLink($id_category, $resultIds[$id_category]['link_rewrite']),
  'name' => $resultIds[$id_category]['name'], 'desc'=> $resultIds[$id_category]['description'],
  'children' => $children, 'products' => $ProductsCount);
}

 

 

Then open the file "category_tree_branch.tpl" that you find in the same folder /modules/blockcategory and find this line (should be line 41):

  <a href="{$node.link}" {if isset($currentCategoryId) && ($node.id == $currentCategoryId)}class="selected"{/if} title="{$node.desc|escape:html:'UTF-8'}">{$node.name|escape:html:'UTF-8'}</a>

 

and change to this:

  <a href="{$node.link}" {if isset($currentCategoryId) && ($node.id == $currentCategoryId)}class="selected"{/if} title="{$node.desc|escape:html:'UTF-8'}">{$node.name|escape:html:'UTF-8'} ({$node.products})</a>
