Wordpress displays posts of category ID
提问by Miker
Can't seem to find the right answer for what I thought would be trivial.
似乎无法为我认为微不足道的事情找到正确的答案。
I have some categories arranged like this...
我有一些这样排列的类别......
Parent Category 1
- Child Category 1
- Child Category 2
- Child Category 3
父类别 1
- 子类别 1
- 子类别 2
- 子类别 3
...and I have some posts that are in Child Category 2. I want my page to display all posts from the category I am currently in.
...我有一些属于子类别 2 的帖子。我希望我的页面显示我当前所在类别的所有帖子。
This is what I am doing right now:
这就是我现在正在做的事情：
<?php
query_posts('cat=2&showposts=10');
if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class="timeline">
<h3><?php the_title(); ?></h3>
<?php the_content();?>
<?php endwhile; else: ?>
<?php _e('No Posts Sorry.'); ?>
<?php endif; ?>
</div>
As you can see I am having to manually specify the category (cat=2), but instead I want it to automatically detect the category I am already in and display the posts (that way if I'm in a different category it will display those posts).
如您所见，我必须手动指定类别 (cat=2)，但我希望它自动检测我已经所在的类别并显示帖子（这样，如果我在不同的类别中，它将显示那些帖子）。
Any suggestions?
有什么建议？

try below code:
试试下面的代码：
<?php
$current_cat_id = get_query_var('cat');
$showposts = 10;
$args = array('cat' => $current_cat_id, 'orderby' => 'post_date', 'order' => 'DESC', 'posts_per_page' => $showposts,'post_status' => 'publish');
query_posts($args);
if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class="timeline">
<h3><?php the_title(); ?></h3>
<?php the_content();?>
<?php endwhile; else: ?>
<?php _e('No Posts Sorry.'); ?>
<?php endif; ?>
</div>

If you are using category.php, you can omit the query_postsand it will auto fill in the posts for you.
如果您正在使用category.php，则可以省略query_posts，它会自动为您填写帖子。

<?php
// Start the loop.
$categories = get_categories('child_of=1');//Parents category id
foreach ($categories as $cat) {
$option = '<a href="/category/archives/'.$cat->category_nicename.'">';
$option .= $cat->cat_name;//parents sub category name
$option .= '</a>';
echo $option;
query_posts('cat=$cat->cat_ID&showposts=10');
if (have_posts()) : while (have_posts()) : the_post(); ?>
<h3><?php the_title(); ?></h3>
<?php the_content();?>
<?php endwhile; else: ?>
<?php _e('No Posts Sorry.'); ?>
<?php endif; }?>

<ul>
<?php
global $post;
$args = array( 'posts_per_page' => 5, 'offset'=> 0, 'category' => 1 );
// 1 is a cat id.
//
$myposts = get_posts( $args );
foreach( $myposts as $post ) : setup_postdata($post); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endforeach; ?>
</ul>
