Custom category page display subcategories with posts

i’ve just posted the exact same request in another topic! here

I know how it could work (as i’ve detailed) but i’m not sure if it’s the correct way of doing it. Technically using the same template page and duplicating some code within it along with incrementing the category variable passed into the page would work. I’m just unsure how to do it in wordpress land.

<?php
$parentCatName = single_cat_title('',false);
$parentCatID = get_cat_ID($parentCatName);
$childCats = get_categories( 'child_of' => $parentCatID );
if(is_array($childCats)):
foreach($childCats as $child){ ?>
    <h2><?php echo $child->name; ?></h2>
<?php
    query('cat='.$child->term_id);
    while(have_posts()): the_post(); $do_not_duplicate = $post->ID;
     //post code stuff here;
    endwhile;
    wp_reset_query();
}
endif;
?>

Try this logic.

great thanks! will give that a go today!

thanks chinmoy29, logical it should work like this. No when I implement it in the category page I get the following error:

Parse error: syntax error, unexpected T_DOUBLE_ARROW in /***/***/public_html/***/wp-content/themes/k2/category.php on line 11

and on line 11 is the following code:\

$childCats = get_categories( ‘child_of’ => $parentCatID );

check the syntax of ‘get_categories()’

https://codex.www.ads-software.com/Function_Reference/get_categories

$childCats = get_categories( 'child_of='.$parentCatID );

or

$childCats = get_categories( array('child_of' => $parentCatID) );

btw:
child_of will also get you the sus-sub-and-so-on categories
parent will only give the direct sub cats

Thank you alchymyth,

I managed to make it work as I wanted. Thank you again. Here is the code that works.

<?php
$parentCatName = single_cat_title(”,false);
$parentCatID = get_cat_ID($parentCatName);
$childCats = get_categories( ‘child_of=’.$parentCatID );
if(is_array($childCats)):
foreach($childCats as $child){ ?>
<h2><?php echo $child->name; ?></h2>
<?php query_posts(‘cat=’.$child->term_id);
while(have_posts()): the_post(); $do_not_duplicate = $post->ID; ?>
<!– POST CODE –>

<!– END POST CODE –>
<?php
endwhile;
wp_reset_query();
}
endif;
?>

Thanks again for helping me.

where should i put the above code..

very sorry i new in wp.is it in side bar.php??

Nevermind…

This is just what I want – BUT it only shows sub categories and omits all posts in the parent category. Would anyone have a tweak to show the top level as well?

how can I use the variable $do_not_duplicate = $post-> ID in this loop for not having duplicate posts?

Best Regards
