How do I get posts from category using the slug?
提问by Nips
I have my own theme and I'd like to display posts on my home page from a specific category.
我有自己的主题，我想在我的主页上显示来自特定类别的帖子。
So far I've achieved it like this:
到目前为止，我已经实现了这样的目标：
<?php
global $post;
$args = array( 'numberposts' => 10, 'category' => 6 );
$posts = get_posts( $args );
foreach( $posts as $post ): setup_postdata($post);
?>
<divs with the_title() the_excerpt() etc ></div>
<?php
endforeach;
?>
But what if I want to get the category by a its slug? Or is it possible to simply make a category selection box in from within the admin panel?
但是如果我想通过它的 slug 来获取类别呢？或者是否可以简单地从管理面板中创建一个类别选择框？

Replace your categoryparameter with category_name
将您的category参数替换为category_name
<?php
global $post;
$args = array( 'numberposts' => 10, 'category_name' => 'cat-slug' );
$posts = get_posts( $args );
foreach( $posts as $post ): setup_postdata($post);
?>
<divs with the_title() the_excerpt() etc ></div>
<?php endforeach; ?>

suppose you have category name 'ice cakes' and category slug as 'ice-cakes', then our code to retrieve post under category 'ice cakes' is as follows:
假设您的类别名称为“ice cakes”，类别 slug 为“ice-cakes”，那么我们在“ice cakes”类别下检索帖子的代码如下：
<?php
$args = array( 'posts_per_page' => 3,
'category_name' => 'ice-cakes' );
$icecakes = get_posts( $args );
foreach ( $icecakes as $post ) : setup_postdata( $post ); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endforeach;
wp_reset_postdata(); ?>
