How to show children's subcategorie's of current categorie in Magento - magento

Question

I am trying to get my big catalog somewhat tablet friendly by offering an selection of tabs with sublevel links for my seperate categories. So if a user clicks a (1st level)head category it needs to display a nr of blocks which hold the picture, description and url of each direct child and a list of all the underlying (3rd level) child categories of the shown (2nd level) categorie. Would any off you guys be so kind to check my code?
<?php
$layer = Mage::getSingleton('catalog/layer');
$_category = $layer->getCurrentCategory();
$_categories = $_category->getCollection()
->addAttributeToSelect(array('url_key','name','image','all_children','is_anchor','description'))
->addAttributeToFilter('is_active', 1)
->addIdFilter($_category->getChildren())
->setOrder('position', 'ASC')
->joinUrlRewrite();
?>
<?php $children = explode( ",", $this->getCurrentCategory()->getChildren() ); ?>
<ul class="category-grid">
<div class="category-list">
<?php foreach( $children as $child ): ?>
<?php $_child = Mage::getModel( 'catalog/category' )->load( $child ); ?>
<li class="item">
<img title="<?php echo $this->htmlEscape($_child->getName()) ?>" src="<?php echo $this->htmlEscape($_child->getImageUrl()) ?>" alt="<?php echo $this->htmlEscape($_child->getName()) ?>" />
<div class="subcategory-title">
<?php echo $this->htmlEscape($_child->getName()) ?>
</div>
<div class="description-block"> <?php echo $_child->getDescription(); ?></div>
<div class="children-links"><?php
$_helper = Mage::helper("catalog/category");
$rootCat = Mage::app()->getStore()->getRootCategoryId();
$current = Mage::registry('current_category');
if ($child){
//look for anchestor
$parentid = $child->getParentId();
$parent = Mage::getModel("catalog/category")->load($parentid);
if($parentid != $rootCat)
{
//find the anchestor
show_cat($parent,$_helper,$rootCat);
}else{
//is root
$_subcategories = $child->getChildrenCategories();
echo $_child->getAll_Children();
if(count($_subcategories)>0){
echo '<ul>';
foreach($_subcategories as $_category){
echo '<li>';
echo ''.$_category->getName().'';
if($child->getId() == $_category->getId()){
$current = Mage::registry('current_category');
if ($current){
//handle current
$_current_subcategories = $current->getChildrenCategories();
if(count($_current_subcategories)>0){
//the current cat has childrens
echo '<ul>';
foreach($_current_subcategories as $_sub_category){
echo '<li>';
echo ''.$_sub_category->getName().'';
echo '</li>';
}
echo '</ul>';
}else{
//the current cat has no childrens
$current_parent = $current->getParentId();
$current_parent = Mage::getModel("catalog/category")->load($current_parent );
$_current_subcategories = $current_parent ->getChildrenCategories();
echo '<ul>';
foreach($_current_subcategories as $_sub_category){
echo '<li>';
echo ''.$_sub_category->getName().'';
echo '</li>';
}
echo '</ul>';
}
}
}
echo '</li>';
}
echo '</ul>';
}
}
}
?>
</div>
</li>
<?php endforeach ?>
</div>
</ul>

Answer 1

you can this by the below code and also refer link at bottom
you could be go with this
<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php $currentCategory = Mage::registry('current_category') ?>
<?php if (count($_categories) > 0): ?>
<ul class="category">
<?php foreach($_categories as $_category): ?>
<li>
<a href="<?php echo $_helper->getCategoryUrl($_category) ?>">
<?php echo $_category->getName() ?>
</a>
<?php if ($currentCategory->getId() && $currentCategory->getId() == $_category->getId()): ?>
<?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
<?php $_subcategories = $_category->getChildrenCategories() ?>
<?php if (count($_subcategories) > 0): ?>
<ul class="subcategory">
<?php foreach($_subcategories as $_subcategory): ?>
<li>
<a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>">
<?php echo $_subcategory->getName() ?>
</a>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
<?php endif; ?>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
EDIT
<ul class="subcategory">
<? foreach ($_categories as $_category):?>
<? if($_category->getIsActive()):
$cur_subcategory=Mage::getModel('catalog/category')->load($_category->getId());
$layer = Mage::getSingleton('catalog/layer');
$layer->setCurrentCategory($cur_subcategory);
?>
<li> <?php echo $_category->getName()?></li>
<? endif;?>
<?endforeach?>
</ul>
Or you can go throw this Detail documentation, i am sure that would be really helpful to you.

Answer 2

// get current category
$current_category = $layer->getCurrentCategory();
// get sub categories of current category
$parent_categories = Mage::getModel('catalog/category')->getCategories($current_category->getId());
// go through each sub category and get their sub categories.
foreach($parent_categories as $child_category)
{
$child_category_id = $child_category->getId();
$grandchild_categories = Mage::getModel('catalog/category')->getCategories($child_category_id);
}

Here is the tested code for showing sub categories. Just put this code above "Toolbar" code in your custom theme "Magento_catalog/templet/product/list.phtml"
<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$category = $objectManager->get('Magento\Framework\Registry')->registry('current_category');//get current category
$subcats = $category->getChildrenCategories();
$_helper = $this->helper('Magento\Catalog\Helper\Output');
$imageHelper = \Magento\Framework\App\ObjectManager::getInstance()->get(\Magento\Catalog\Helper\Image::class);
if(count ($subcats) > 0)
{
?>
<div class = "sub-cat-div">
<ul class = "sub-cat-main">
<?php
foreach ($subcats as $subcat) {
if ($subcat->getIsActive()) {
$_category = $objectManager->create('Magento\Catalog\Model\Category')->load($subcat->getId());
$_outputhelper = $this->helper('Magento\Catalog\Helper\Output');
$subcaturl = $_category->getUrl();
$_imgHtml = '';
if ($_imgUrl = $_category->getImageUrl()) {
$_imgHtml = '<img src="' . $_imgUrl . '" />';
$_imgHtml = $_outputhelper->categoryAttribute($_category, $_imgHtml, 'image');
echo '<li class="sub-cat-image">' . $_imgHtml . '<span style="background-color: rgba(255,255,255,0.9)" class="content bg-white"><strong>' . $_category->getName() . '</strong></span></li>';
}
else{
$_imgUrl = $imageHelper->getDefaultPlaceholderUrl('image');
$_imgHtml = '<img src="' . $_imgUrl . '" />';
$_imgHtml = $_outputhelper->categoryAttribute($_category, $_imgHtml, 'image');
echo '<li class="sub-cat-image">' . $_imgHtml . '<span style="background-color: rgba(255,255,255,0.9)" class="content bg-white"><strong>' . $_category->getName() . '</strong></span></li>';
}
}
} ?>
</ul>
</div>
<?php
}
?>
