Magento: Display sub-category list_问答_开发者

I'm building a Magento store and want to be able to display a list of categories and have each category link t开发者_运维知识库o its own page.

I have a 'Brands' category with an ID of 42 and I want to display a list of the sub-categories and ensure that each one links to the designated URL key in the CMS.

Has anyone had experience of doing this with Magento?

If you're comfortable editing your theme, this code snippet will bring you a list of all sub-categories of the current category (from the session, so this should work anywhere in your theme). I typically use this in app/design/frontend/default/theme_name/template/catalog/category/view.phtml

<?php
$_category  = $this->getCurrentCategory(); 
$collection = Mage::getModel('catalog/category')->getCategories($_category->entity_id);
$helper     = Mage::helper('catalog/category');
?>

<ul>
    <?php foreach ($collection as $cat):?>
            <?php if($_category->getIsActive()):?>
                <?php 
                     $cur_category = Mage::getModel('catalog/category')->load($cat->getId());
                     $_img = $cur_category->getImageUrl();  
                ?>
                <li>
                    <a href="<?php echo $helper->getCategoryUrl($cat);?>">
                         <img src="<?php echo $_img?>" title="<?php echo $cat->getName();?>"/>
                         <cite><?php echo $cat->getName();?></cite>
                    </a>
                </li>
            <?php endif?>
    <?php endforeach;?>
</ul>

If You want to Display top level categories and subcategories U can do Like This..

<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php $currentCategory = Mage::registry('current_category') ?>
<?php if (count($_categories) > 0): ?>
<ul>
    <?php foreach($_categories as $_category): ?>
        <li>
            <a href="<?php echo $_helper->getCategoryUrl($_category) ?>">
                <?php echo $_category->getName() ?>
            </a>
            <?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
            <?php $_subcategories = $_category->getChildrenCategories() ?>
            <?php if (count($_subcategories) > 0): ?>
                <ul>
                    <?php foreach($_subcategories as $_subcategory): ?>
                        <li>
                            <a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>">
                                <?php echo $_subcategory->getName() ?>
                            </a>
                        </li>
                    <?php endforeach; ?>
                </ul>
            <?php endif; ?>
        </li>
    <?php endforeach; ?>
</ul>
<?php endif; ?>

For Displaying Top Level Categories and Current Categories SubCategories you can Do like ....

<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php $currentCategory = Mage::registry('current_category') ?>
<?php if (count($_categories) > 0): ?>
<ul>
    <?php foreach($_categories as $_category): ?>
        <li>
            <a href="<?php echo $_helper->getCategoryUrl($_category) ?>">
                <?php echo $_category->getName() ?>
            </a>
            <?php if ($currentCategory && $currentCategory->getId() == $_category->getId()): ?>
                <?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
                <?php $_subcategories = $_category->getChildrenCategories() ?>
                <?php if (count($_subcategories) > 0): ?>
                    <ul>
                        <?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; ?>

This question requires a long answer. I will point you to the right places.

1) Best solution is to use the free extension. I haven't tried it, but it will suit the purpose. You will have to do some CSS to achieve the right look and feel.

2) I do not trust in modules as it might become difficult to upgrade if the vendor decided to stop supporting it. I have used the information from the following forum thread to create a vew sites. Have a look... Might not be straight forward. You might have to make some copies of core files to the local directory.

Hopefully this will be of help to you :)

I made this little video on how I create custom category listing blocks with Magento. I am sure there are better ways of achieving this or even something I could have done better, but it’s just my method. I only created this it in hopes that it helps explain somethings to some people out there.

Magento Custom Category Listing Block

Thanks!

after looking at all the solutions on the magento site, i found that wookiehangover's solution above worked and took about 8 seconds to implement.

creates a UL that you can style. thanks.

After creating static block you can get any list of the subcategories by this script:

        $_helper = Mage::helper('catalog/category');
        $_category = Mage::getModel('catalog/category')->load(5);
        $_subcategories = $_category->getChildrenCategories();

        if (count($_subcategories) <= 0) { return; }

        $count = 0;

        foreach($_subcategories as $_category) {     
                                                      $category = Mage::getModel('catalog/category')->load($_category->getId());

                                                      $ret->{"object_".$count} ->url  = $_helper->getCategoryUrl($_category);
                                                      $ret->{"object_".$count} ->name = $_category->getName();
                                                      $ret->{"object_".$count} ->id =  $_category->getId(); 
                                                      $ret->{"object_".$count} ->image =   $category->getImageUrl();
                                                      $count++;
                                                   } 

        return $ret;                                          

        } 


$list = list_subcategories(5);

echo "<pre>"; print_r($list); echo "</pre>";
?>

How about listing only the categories belonging to the current item. Not all the categories on the page.

But in a tree like view.

CATEGORIE - sub cat 1 CATEGORIE 2 - sub cat 1 - sub sub cat 1
