Category Filter Help

    I’m getting very confused (very easy to achieve!) by categories. I have a page which is displaying a category set, this includes links to the contained categories.


    Example, cat set strengthening, this set includes categories such as, Neck, Elbow etc…


    When someone clicks on Neck, I want a page to display all the items that are categorised as Neck. If they click on Elbow, everything categorised as Elbow appears. etc.


    Here is where I am at currently, tried various methods, such as trying to filter, sort and so on without success.


    PHP: Current Template
    1. $template    =    'strengthening/list.html';
    3. perch_collection('Strengthening', [
    4. 'template' => $template,
    5. 'category' => array('strengthening/neck', 'strengthening/shoulder-girdle', 'strengthening/elbow', 'strengthening/wrist-and-hand', 'strengthening/thoracic-spine', 'strengthening/lumber-spine', 'strengthening/gluteals', 'strengthening/hip', 'strengthening/knee', 'strengthening/ankle', 'strengthening/foot', 'strengthening/functional-mobility'),
    6. 'filter' => 'catSlug',
    7. 'match' => 'eq',
    8. ]);


    This template, displays all my categories regardless of filtering and sorting. Hence I think this my issue has something to do with category => array, but what should be in its place?


    Thanks in advance

    Hi, thank you for the responses and I now realise I haven't explained the "issue" very well.


    I previously found and read the Filtering article, and it did move me towards an answer. The article has two methods as an example. Show a single category, or display all categories.


    I wish to display a single category on my Collection -> Index page. However, this page changes in accordance with the catSlug clicked. Hence the page dynamically changes.


    I have a URL Pattern set on this page which is strengthening/category/[slug:cat].


    To hopefully illustrate further. In the Blog App, if you have Categories listed, you can click the Category link, and then a Page (Blog Archive) is presented with only those Blog articles that match that category. This is what I am trying to achieve, however, with a collection.


    Apologies for not articulating this very well in the first instance. Fingers crossed, this is now corrected.

    The Blog app doesn't require you to use the full category path. It prefixes the category path with blog/ under the hood.


    Elsewhere in Perch, you can filter items by multiple categories from different category sets. So you need to use the full category path e.g. strengthening/neck/.



    PHP
    1. if(perch_get('cat')) {
    2. perch_collection('Strengthening', [
    3. 'category' => 'strengthening/' . perch_get('cat') . '/'
    4. ]);
    5. }
