    <?php
$all_cats = wp_list_categories('hide_empty=0&amp;title_li=&amp;child_of=4');
foreach( $all_cats as $cat ) :
?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php
endforeach;
?>

    What I’m trying to do is to show ALL needed categories with IT’S posts …
    But I’m stuck with this code … it shows all cats that i need, but in the end of it I see an Error:

    Warning: Invalid argument supplied for foreach() in K:\home\test1.ru\www\wp-content\themes\artel\header.php on line 78

    Can somebody give me a right solution for this ?

    That is what im trying to do … i think it’s clear:

    <?php
$all_cats = wp_list_categories('hide_empty=0&amp;title_li=&amp;child_of=4');
foreach( $all_cats as $cat ) :
?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<ul>
   <?php
       $stringGetPosts = "numberposts=0&amp;category='".the_ID()."'4&amp;orderby=menu_order&amp;order=ASC";
       get_posts($stringGetPosts);
   ?>
</ul>
</li>
<?php
endforeach;
?>

    Try adding…

    &amp;echo=0 to the list cats function call.

    It outputs the result by default, so you need to stop that firstly….
