Hi!
I need a code to display all my subcategories within posts for single.php:
like this:
subcategory 1(if existing)
- post 1
- post 2
- post n
subcategory 2(if existing)
- post 1
- post 2
- post n
subcategory n(if existing)
- post 1
- post 2
- post n
thanks for respone
in general:
get the category id of the categories of the post
http://codex.wordpress.org/Function_Reference/wp_get_post_categories
foreach of the above - get the sub categories
http://codex.wordpress.org/Function_Reference/get_categories
'child_of' parameter to include sub-sub cats
'parent' parameter to get only direct sub categories
foreach of these sub categories - get the posts
http://codex.wordpress.org/Template_Tags/get_posts
'numberposts=-1' to show all posts
'cat=' to get the posts of the subcategory

hi alchymyth!
thanks 4 your response. i do have a code working on the category.php. but -and i am more webdesigner than programmer ;-) - i am not sure why it doesn't work on the single.php.
maybe you could have a look and help me out: THX
foreach((get_the_category()) as $category)
{
$postcat= $category->cat_ID;
$catname =$category->cat_name;
}
<h2><?php echo $catname; ?></h2>
<?php $categories = get_categories("child_of=5"); foreach ($categories as $cat) { ?>
<?php query_posts("cat=$cat->cat_ID&showposts=-1&order=ASC&orderby=name"); ?>
<h3><?php single_cat_title(); ?></h3>
<?php while (have_posts()) : the_post(); ?>
<div class="what">
<h3><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to
<?php the_title_attribute(); ?>"><?php the_title(); ?></a></h3>
</div>
<?php endwhile; ?>
<?php } ?>
<?php
$post_categories = wp_get_post_categories( $post->ID );
foreach($post_categories as $c){
$cat = get_category( $c );
echo "<h1>". $cat->name . "</h1>";
$childCats = get_categories( array('child_of' => $c) );
if(is_array($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 stuff here;
endwhile;
wp_reset_query();
}
endif;
}
?>write this in single.php file.
see this also this code for category.php or archive.php
http://wordpress.org/support/topic/custom-category-page-display-subcategories-with-posts?replies=7
also see this http://wordpress.org/support/topic/category-navigation-`on-singlephp?replies=9
$postcat= $category->cat_ID;
$catname =$category->cat_name;`
would be
$postcat= $category->term_id;
$catname =$category->name;

$cat = get_category( $c );
echo "<h1>". $cat->name . "</h1>";

a little problem..the result is perfect.. just one tiny little thing:
at the end (have a look:
http://www.goodandbad.net/sport-akustik/limited/perfekte-akustik-im-fur-forschung-und-lehre/)
it writes one subcategory (presse)with with the style of the category (<h2>)
but i just want to display the parent category with <h2> on top (Ltd.)
<?php
$post_categories = wp_get_post_categories( $post->ID );
foreach($post_categories as $c){
$cat = get_category( $c );
echo "<h1>". $cat->name . "</h1>";
$childCats = get_categories( array('child_of' => $c) );
if(is_array($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 stuff here;
endwhile;
wp_reset_query();
}
endif;
}
?>Presse should not be displayed.
would be glad if this could be fixed.
replace this echo "<h1>". $cat->name . "</h1>"; with echo "<h2>". $cat->name . "</h2>";

no, that is not the problem.:)
the problem is that the function :
echo "<h1>". $cat->name . "</h1>";
writes 2 categories. one at the beginning - which is good and one at the end (which is a subcategory in category-style) .
i think the foreach function is placed wrong. hope u know what i mean.
thx anyway
One will show parent category name and another will be subcategory name.
Now it is display this way.
chnage this line echo "<h1>". $cat->name . "</h1>"; with this
if($cat->parents)
echo "<h1>". $cat->name . "</h1>";

nope. writes nothing..
everything else is fine. i just need the parent category. and best outside any loop.
echo(get_category_parents($cat, TRUE, ' » '));
writes for example
category >>
subcat
post
subcat
post
category >> subcategory
I am so busy. If you want to contact with me, sent mail chinmoy29 at gmail dot com
