Hello Dzukis,
For the front page to show posts from a specific category rather than all latest posts, you can modify the query with pre_get_posts. Here is an example of how to make the front page show posts only from the ‘travel’ category:
function mauer_frontpage_categories($query)
{
if ($query->is_main_query() && is_front_page()) {
$query->set( 'category_name', 'travel' );
}
return $query;
}
add_action( 'pre_get_posts', 'mauer_frontpage_categories' );
This code should be placed in functions.php of your theme. Or in a child theme / plugin, which would save it from being overwritten when you update the theme.
Hope that helps.
