Post Order By DESC

Hi there.

1. try this snippet to order alphabetically by title:

add_action( 'pre_get_posts', function( $query ) {
  if ( $query->is_main_query() && ! is_admin() ) {
      $query->set( 'orderby', 'title' ); 
      $query->set( 'order', 'ASC' ); 
  }
} );

2. Just to be clear, on a parent category page you don't want to list ANY posts ? Just a list of child categories ?

Hi David...

Thanks for your fast reply.....

Regarding to item 2, Yes...on a parent category I dont want to list any post..but display child categories of that parent category with count of post in each child category.............and display posts only in child categoy.....

Like this...........

Ok try this PHP Snippet:

add_action('wp', function(){
    if ( is_category() ) {
        $term = get_queried_object();
        if ( $term->parent == 0 ) {
            add_filter( 'generate_do_template_part', function( $do ) { return false; });
            add_action('generate_after_loop', 'db_show_the_children_categories');
            remove_action( 'generate_after_loop', 'generate_do_post_navigation' );	
        }
    }
});

function db_show_the_children_categories(){
	$cat = get_category( get_query_var( 'cat' ) );
	$cat_id = $cat->cat_ID;
	$child_categories=get_categories(
    	array( 
            'parent' => $cat_id,
            'order' => 'ASC'
        )
	);
    echo '<ul class="child-categories">';
	foreach ( $child_categories as $child ) {
        $child_html = sprintf(
            '<li><a href="%1$s">%2$s</a><span class="count">%3$s</span></li>',
            esc_url( get_category_link( $child->term_id ) ),
            esc_html( $child ->cat_name ),
            esc_html( $child ->count )
        );
    	echo $child_html;
	}

    echo '</ul>';
}

Way it works is to first check if were on a parent category and if so it sets the generate_do_template_part to bypass the posts being output in the loop, and then hooks in the custom db_show_the_children_categories to show a list of subcategories.

And a little CSS for basic styling:

.child-categories {
	list-style: none;
	width: 100%;
}
.child-categories li {
	border-bottom: 1px solid #ccc;
}
.child-categories .count {
	margin-left: 10px;
	background-color: #000;
	color: #fff;
	padding: 0 10px;
	border-radius: 1em;
}

Thank you David.....That's first class service!!!!

Awesome - glad to be of help!

I have inserted the codes...and its perfect!!..

Only that paging shouldn't show in child-categoris list.....How to solve that??

Ah.. i made an edit to the snippet here:

https://generatepress.com/forums/topic/post-order-by-desc/#post-2229418

the change is just to the first code block. The line added was:

remove_action( 'generate_after_loop', 'generate_do_post_navigation' );

Done....Thanks....

You're welcome

Hi David...

What to change in the code for this case??:

Parent 
-Child (count)
--Grandchild (count)

-----------------------------------------------------------------
add_action('wp', function(){
    if ( is_category() ) {
        $term = get_queried_object();
        if ( $term->parent == 0 ) {
            add_filter( 'generate_do_template_part', function( $do ) { return false; });
            add_action('generate_after_loop', 'db_show_the_children_categories');
            remove_action( 'generate_after_loop', 'generate_do_post_navigation' );	
        }
    }
});

function db_show_the_children_categories(){
	$cat = get_category( get_query_var( 'cat' ) );
	$cat_id = $cat->cat_ID;
	$child_categories=get_categories(
    	array( 
            'parent' => $cat_id,
            'order' => 'ASC'
        )
	);
    echo '<ul class="child-categories">';
	foreach ( $child_categories as $child ) {
        $child_html = sprintf(
            '<li><a href="%1$s">%2$s</a><span class="count">%3$s</span></li>',
            esc_url( get_category_link( $child->term_id ) ),
            esc_html( $child ->cat_name ),
            esc_html( $child ->count )
        );
    	echo $child_html;
	}

    echo '</ul>';
---------------------------------------------------------------------------

Try this code instead:

add_action('wp', function(){
    if ( is_category() ) {
        $term = get_queried_object();
        if ( $term->parent == 0 ) {
            add_filter( 'generate_do_template_part', function( $do ) { return false; });
            add_action('generate_after_loop', 'db_show_the_children_categories');
            remove_action( 'generate_after_loop', 'generate_do_post_navigation' );	
        }
    }
});

function db_show_the_children_categories(){
	$cat = get_category( get_query_var( 'cat' ) );
	$cat_id = $cat->cat_ID;
	$child_categories=get_categories(
    	array( 
            'parent' => $cat_id,
            'order' => 'ASC'
        )
	);
    echo '<ul class="child-categories">';
	foreach ( $child_categories as $child ) {
        
        $child_html = sprintf(
            '<li><a href="%1$s">%2$s</a><span class="count">%3$s</span>',
            esc_url( get_category_link( $child->term_id ) ),
            esc_html( $child ->cat_name ),
            esc_html( $child ->count )
        );
    	
        $grandchild_categories = get_terms( $child->taxonomy, array(
            'parent'    => $child->term_id,
            'hide_empty' => false
        ) );
        if ( $grandchild_categories ) {
            $child_html .= '<ul class="child-categories">';
                foreach ( $grandchild_categories as $grandchild ) {
                    $child_html .= sprintf(
                        '<li><a href="%1$s">%2$s</a><span class="count">%3$s</span></li>',
                        esc_url( get_category_link( $grandchild->term_id ) ),
                        esc_html( $grandchild ->name ),
                        esc_html( $grandchild ->count )
                    );
                }
            $child_html .= '</ul>';
        }
        $child_html .= '</li>'; 
        echo $child_html;

	}

    echo '</ul>';
}

Thanks for your help, David....
