Categories and Perch Runway

Hi Guys,

I have never really used categories much and so I am a little stuck/lost. Wondered if you can perhaps give me some direction.

I have created a list and details page and I want to be able to filter the stories based on the categories. So if you click one of the categories in then it would show you a list of all stories for that category.

I have setup my cats in the backend and I have my list and details page working. But not I am trying to filter I am stumped. I am not sure what I need to setup in order to achieve this? I assume I would do the filtering with some if statements on the same stories.php template where my list/details are shown, but as this is runway I am also unsure about what routes to add etc?

Thanks in advance

What do you want the URLs to be?

For example;

Are age-group and diagnosis your category sets?

Yes they are

What does your detail page URL look like?

Ok, so I think you need routes like


Then logic like:

if (perch_get('story') {
   // ... detail mode ...
} else {
   // ... list mode ...

    if (perch_get('cat')) {
        $catPath = perch_get('set') .'/'. perch_get('cat');
        // ... listing filtered by category ...
       // use 'category' => $catPath,
        // ... unfiltered listing ...


Thanks for this Drew. I have it all working now as I would like.
However, I have one further question.

I am doing a check on the details page if it exists and throwing a 404 error if not with this code.

if (perch_get('story_slug')) {
    $result = perch_content_custom('Stories', [
        'template'          => 'stories/story',
        'filter'            => 'story_slug',
        'match'             => 'eq',
        'value'             => perch_get('story_slug'),
        'count'             => 1,
        'skip-template'     => true,
        'return-html'       => true,

    //This Code redirects to a 404 error if there is no result
    if(count($result) < 2) {

This works fine. But how can i do the same for the Categories?

For example if I try any URL like;
stories/diagnosis/acute-lymphoblastic-leukaemiasssssss/ or even stories/test/testing

then I get the page back but without any content. Ideally I would like to 404 any incorrect category URLS.

Thanks, Terry

You can use perch_category() to test if the category exists.
