[英]Wordpress: get last post belonging to a category, when listing categories
I've tried looking at the database but I can't seem to be able to make a query to do this. 我尝试查看数据库,但似乎无法进行查询。 How can I look up posts from only one category, or more specifically, I just need the ID of the last post from the category.
如何只查找一个类别的帖子,或更具体地说,我只需要该类别的最后一个帖子的ID。
I'm trying to do this in index.php 我正在尝试在index.php中执行此操作
Using get_posts
will do what you need, documentation here 使用
get_posts
您的需求, 此处提供文档
something along the lines of the following 遵循以下内容
<?php
$postsincat = get_posts(array("cat" => 1, "showposts" => 1));
$idoflatestpostincategory = $postsincat[0]->ID;
?>
You could also use category_name
instead of cat
in the array to use a name instead of ID. 您也可以在数组中使用
category_name
代替cat
来使用名称代替ID。
