Category Filtering

Once you have created categories and assigned them to Perch Content you can filter content by category or multiple categories.

Categories are filtered using their category path, which is made up using the set slug and the category slug. For example, if you wanted to filter by the category red in the set called colours, the path would be:

colours/red

If there was a subcategory of red called scarlet, you would filter for that using:

colours/red/scarlet

Example – filtering by a single category

    perch_content_custom('Portfolio', array(
      'template' => 'portfolio_listing.html',
      'page' => '/portfolio.php',
      'category' => perch_get('cat'),
    ));

Example – filtering by multiple categories

The below example uses not syntax. We want all T-shirts that are size XL, male but not black.

    perch_content_custom('T-shirts', array(
       'category' => array('size/xl', '!colour/black', 'gender/male')
    ));

Matching multiple categories

You can change the way Perch matches when filtering on multiple categories by setting the category-match option.
