Hogyan lehet wordpressben üres kategória figyelmeztetést kiírni?

Pl:

<?php

$args=array(

'child_of' => 4,

'orderby' => 'name',

'order' => 'ASC',

'hide_empty' => '0'

);

$categories=get_categories($args);

foreach($categories as $category) {

echo '<h3>' . $category->name . '</h3>

<div>';

global $post;

$args = array( 'posts_per_page' => -1, 'category' => $category->term_id, 'orderby' => 'name', 'order' => 'ASC' );

//alternatively this also works: 'nopaging' => true

$myposts = get_posts( $args );

if (!$myposts) {

echo 'Sorry there are currently no classes in this category';

}

else {

foreach( $myposts as $post ) : setup_postdata($post);

echo '<p><a href="' . get_permalink($post->ID) . ' " style="color:#7c7c7c; font-size: 1em; text-decoration:none !important; line-height:80%;">' . get_the_title($post->ID) . '</a></p>';

endforeach;

}

echo '</div>

';

}

?>
