Wordpress: $categories as $category - sort by date

Question

I've got the following code to show all categories and the last post in a category - using Wordpress:

foreach( $categories as $category ) {
$category_link = sprintf( 
   '<a href="%1$s" alt="%2$s">%3$s</a>',
    esc_url( get_category_link( $category->term_id ) ),
    esc_attr( sprintf( __( 'View all posts in %s', 'textdomain' ),
    $category->name ) ),
    esc_html( $category->name )
                        );

global $post;
$args = array( 'posts_per_page' => 1,  'category' => $category->term_id);

$myposts = get_posts( $args );
foreach ( $myposts as $post ) : setup_postdata( $post ); 
$newpost="<a href=".get_the_permalink()."><b>".get_the_title()."</b></a>
$newdate=get_the_date();
endforeach; 

Right now the categories are sorted by alphabet.

Is there a way to sort them by the date of the last post?

I thought about putting an argument to the first line like:

 foreach( $categories as $category sort by ... )

But I couldn't find a way.

Maybe you can help?

Thank you for your help!

Just found this working code: get_categories order by last post

Answer 1

You can sort records of $categories like :

$categories = array('post_status'=>'publish','post_type' => 'test', 'orderby' => 
'date', 'order' => 'DESC','paged' => $paged );
