Usage examples

Using the default template.

<?php perch_blog_categories(); ?>

Use an options array to change the template being used.

        'template' => 'category_link.html',

Pass true as the second argument to return the value rather than echo it.

    $categories = perch_blog_categories(array(
        'template' => 'category_link.html',
    ), true);

Adding fields to categories

The master template for categories is category.html. You can add editable fields to a category by adding them to this template.

<perch:blog id="desc" type="text" label="Description">

Those fields can then be displayed with the category, and can be used to filter the list. For example, you could add a checkbox to toggle the visibility of a category.

<perch:blog id="visible" type="checkbox" value="1" label="Show on site">

And then filter the list by that field.

        'template' => 'category_link.html',
        'filter' => 'visible',
        'match' => 'eq',
        'value' => '1',
