Alright guru's!

 

I need some help.

 

I have a two tiered navigation structure on a site for work; one is the main navigation, and when the user selects that, they see ALL posts within that and all sub categories, now that is working fine. What I need to do, is in a sidebar, to list all sub-categories of the selected category.

 

At the moment I have:

 

<?php wp_list_categories('title_li=&child_of=3'); ?>

 

But I need to make 'child_of' the current category in the URL - does that makes sense?

Have you looked at the codex?

http://codex.wordpress.org/Function_Reference/get_the_category

Not sure how to integrate it to be honest but it should be fairly straightforward to extract the category and put it in your wp_list_categories

Hi Jay,

 

Yes I have had a look - I have the category stored in a variable, but how do I input that as an argument?

 

I currently have:

 

<?php wp_list_categories('title_li=&child_of=$parent'); ?>

 

But that isn't working

 

Help

Very close my friend. Just need to change the single quotes to double quotes or concatenate the parent to the string

first method

<?php wp_list_categories("title_li=&child_of=$parent"); ?>

second method

<?php wp_list_categories('title_li=&child_of='.$parent); ?>

Personally I would go for the second method. I'm not a fan of putting variables directly into strings, but either will work

Cheers Jay - thanks man

No problem

Argh - bugger! Sorry Jay, one more question mate...

 

I am using this code to get the parent category:

 

<?php
$category = get_the_category(); 
$cats = $category[0]->term_id;
echo $cats;
?>

 

BUT the problem is, it is pulling the categories into the array in alphabetic order, rather than numerical order... or just the highest ranking (or parent) page - any idea how I would tell the array to do it in number order instead of alpha?

 

Cheers

Can you put the following after your first line and paste the output here so that I know what the array looks like

echo '<pre>'.print_r($category, true).'</pre>';

Sure - here you go:

 

(
   [0] => stdClass Object
       (
           [term_id] => 29
           [name] => Charity Performance
           [slug] => charityperformance
           [term_group] => 0
           [term_taxonomy_id] => 29
           [taxonomy] => category
           [description] => 
           [parent] => 3
           [count] => 1
           [object_id] => 1
           [cat_ID] => 29
           [category_count] => 1
           [category_description] => 
           [cat_name] => Charity Performance
           [category_nicename] => charityperformance
           [category_parent] => 3
       )

   [1] => stdClass Object
       (
           [term_id] => 3
           [name] => Homepage
           [slug] => anthony-nolan
           [term_group] => 0
           [term_taxonomy_id] => 3
           [taxonomy] => category
           [description] => 
           [parent] => 0
           [count] => 4
           [object_id] => 1
           [cat_ID] => 3
           [category_count] => 4
           [category_description] => 
           [cat_name] => Homepage
           [category_nicename] => anthony-nolan
           [category_parent] => 0
       )

)

$category = get_the_category();
$term = 9999999;
foreach($category as $cat) {
$term = ($cat->term_id < $term) ? $cat->term_id ? $term;
}
echo $term;

Try that

Sorry dude:

 

I got this...

 

Parse error: syntax error, unexpected ';' in C:\Program Files\xampp\htdocs\intranet\wp-content\themes\greenroom\sidebar.php on line 5

 

Line 5:

 

$term = ($cat->term_id < $term) ? $cat->term_id ? $term;

 

Oops should have tested lol

$term = ($cat->term_id < $term) ? $cat->term_id : $term;

:clapping: :clapping:

 

Thank you dude!!

 

It works

 

Cheers

No problem
