Get category URL key in Magento
提问by marchemike
How do I get the URL key of a category in Magento. I have added this text in URL key field the CMS:
如何在 Magento 中获取类别的 URL 键。我在 CMS 的 URL 键字段中添加了此文本：
Category-1
This is how I'm currently trying to show my category URL in an anchor:
这就是我目前尝试在锚点中显示我的类别 URL 的方式：
$_categories = Mage::getModel('catalog/category')->getCollection()
->addAttributeToSelect('name')
->addAttributeToSelect('is_active');
<?php foreach($_categories as $_category): ?>
<a href="<?php echo $_category->getCategoryUrl($_category); ?>">
<?php endforeach; ?>
But whenever I check my output it still shows like this:
但是每当我检查输出时，它仍然显示如下：
<a href="">
<span>Manual Tile Cutters</span>
</a>
I have already checked google and the magento forums for this, but I still cannot find a sufficient answer.
我已经为此检查了 google 和 magento 论坛，但我仍然找不到足够的答案。
Also, is what I'm trying to call in the anchor the URL key, or is it a different URL?
另外，我试图在锚中调用 URL 键，还是不同的 URL？

Both other answers there is a DB penalty. Best way to add Category URL info is at the collection level and simply use it to your liking in your template files. Adjust your code as follows:
其他两个答案都有 DB 惩罚。添加类别 URL 信息的最佳方法是在集合级别，只需在模板文件中根据您的喜好使用它即可。调整您的代码如下：
$_categories = Mage::getModel('catalog/category')->getCollection()
->addAttributeToSelect('name')
->addAttributeToSelect('is_active')
->addUrlRewriteToResult();
<?php foreach($_categories as $_category): ?>
<a href="<?php echo $_category->getUrl($_category); ?>">
<?php endforeach; ?>
Notice the additional method applied to the Category Collection called addUrlRewriteToResult()and call the url by using the getUrl()instead of what you had before which was getCategoryUrl()(no such thing in the code).
请注意应用于 Category Collection 的附加方法调用addUrlRewriteToResult()并使用 url 来调用 url，getUrl()而不是使用之前的内容getCategoryUrl()（代码中没有这样的东西）。
By the way, your code should work just fine if you call getUrl()but will impact performance slightly.
顺便说一句，如果您调用，您的代码应该可以正常工作，getUrl()但会稍微影响性能。
I hope this helps.
我希望这有帮助。

Maybe i did not understand the question completely but the code below will give you the url of a category given the id
也许我没有完全理解这个问题，但下面的代码会给你一个给定 id 的类别的 url
<?php $category = Mage::getModel('catalog/category')->load(4); ?>
<a href="<?php echo $category->getUrl(); ?>">
Simply change the id 4 inside load() with the one you need
只需将 load() 中的 id 4 更改为您需要的

Using Magento (Category-) models might become very heavy to load just for loading the URL of category. When you're in a loop where you need to load the URL's of 9000+ category URL's you might consider using the url rewrite functionality to fetch the URL's since it doesn't involve loading numerous Magento models:
使用 Magento (Category-) 模型可能会变得非常繁重，仅用于加载类别的 URL。当您处于需要加载 9000 多个类别 URL 的 URL 的循环中时，您可能会考虑使用 url 重写功能来获取 URL，因为它不涉及加载众多 Magento 模型：
$requestPath = Mage::getSingleton('core/url_rewrite')
->getResource()
->getRequestPathByIdPath(
'category/' . $categoryId, Mage::app()->getStore()->getId());
return Mage::getBaseUrl() . $requestPath;

Use Mage::helper('catalog/category') for this
为此使用 Mage::helper('catalog/category')
<?php $_helper= Mage::helper('catalog/category');
$_categories = Mage::getModel('catalog/category')->getCollection()
->addAttributeToSelect('name')
->addAttributeToSelect('is_active'); ?>
<?php foreach($_categories as $_category): ?>
<a href="<?php echo $_helper->getCategoryUrl($_category); ?>">
<?php echo $_category->getName(); ?>
</a>
<?php endforeach;?>

If you want to retrieve a collection of store wise category attributes and category url , you can use
如果要检索商店明智的类别属性和类别 url 的集合，可以使用
$collection = Mage::getModel('catalog/category')->getCollection()
->setStoreId($store->getId())
->addAttributeToSelect('entity_id')
->addAttributeToSelect('url_key')
->addAttributeToSelect('name')
->addAttributeToFilter('is_active', 1)
->addAttributeToFilter('include_in_menu', 1)
->addFieldToFilter('path', array('like'=> "1/{$rootCategoryId}/%"));
$collection->getSelect()->joinLeft(
array('url_rewrite_table' => $collection->getTable('core/url_rewrite')),
"url_rewrite_table.store_id = {$store->getId()} AND id_path = CONCAT('category/',e.entity_id)",
array('store_url_key' => 'request_path'
)
);
And retrieve request path like $row->getStoreUrlKey() and prefix it with the store base Url. I am using this to show store specific category grid in the admin panel.
并检索像 $row->getStoreUrlKey() 这样的请求路径，并在它前面加上商店基础 Url。我正在使用它在管理面板中显示商店特定的类别网格。

<?php
// View your current directory
echo getcwd();
//create a file handler by opening the file
$myTextFileHandler = @fopen(getcwd()."/../error-20180726.log","r+");
//truncate the file to zero
//or you could have used the write method and written nothing to it
@ftruncate($myTextFileHandler, 0);
