PHP help, a simple coding a while loop

If I wanted to echo the current category_description using these functions:

as it stands, if I do something like this it only shows the earliest category created.
{?php elsecategories())?}

{?php echo category_description(); ?}

{?php endif; ?}

If I add a while loop, it shows all the category_descriptions. I onlyb want to show the CURRENT description of the page.

Here are your functions:
categories()

Loops through every category, one by one. Returns true when there is more
categories to be listed or false when we are at the end.
Should be used like this:

{?php while(categories()): ?}
<!-- Loop through the categories. -->
{?php endwhile; ?}

category_count
Returns the number of posts that are in the current category.

category_description
Returns the current category description.

category_id
Returns the current category ID.

category_slug
Returns the current category url slug.

category_title
Returns the current category title.

category_url
Returns the full current category url.

total_categories
Returns the number of categories.

 

Not sure I made it clear, but what I am trying to do is to correctly identify the category_description for each page using the functions I listed.

just echoing the function category_description doesn't work, as it appears to only see the first category I created. Somehow I need to collect the category_ids and attach them to the category_descriptions prior to echoing the output, if that makes sense.

 

I'm getting an unexpected '[' on the if line.

 

yeah, i fixed it the way you said, but it can't find the array: 'id' or category_id either. When I look into the phpmyadmin, the actual database entry is anchor_categories and there is an id in the table. However, anchor doesn't actually use the actual database table name, rather it has a function system.

{?php

/**
* Theme functions for categories
*/

function total_categories() {
if( ! $categories = Registry::get('categories')) {
$categories = Category::get();

$categories = new Items($categories);

Registry::set('categories', $categories);
}

return $categories->length();
}

// loop categories
function categories() {
if( ! total_categories()) return false;

$items = Registry::get('categories');

if($result = $items->valid()) {
// register single category
Registry::set('category', $items->current());

// move to next
$items->next();
}

return $result;
}

// single categories
function category_id() {
return Registry:rop('category', 'id');
}

function category_title() {
return Registry:rop('category', 'title');
}

function category_slug() {
return Registry:rop('category', 'slug');
}

function category_description() {
return Registry:rop('category', 'description');
}

function category_url() {
return base_url('category/' . category_slug());
}

function category_count() {
return Query::table(Base::table('posts'))
->where('category', '=', category_id())
->where('status', '=', 'published')->count();
}
