Custom Output
Shortcode output can be overridden within a theme or child theme. To do so, create the following PHP files either in your theme root or in a templates subdirectory:
hestia-ancestors.php
hestia-attachments.php
hestia-children.php
hestia-siblings.php
hestia-sitemap.php
These templates do not work the same as a standard WordPress loop - They are rendered using the Plates template system with an array of WP_Post
objects.
View the existing plugin templates to get an idea of what data will be available in a given file.
A Note About Custom Templates And Post Meta
By default, all queries are performed WITHOUT updating the meta cache unless thumbnails are enabled. It is done this way to minimize the number of database queries performed.
However - if you need to create a custom shortcode template that does access post meta, the result will be an extra database query PER POST!
This is obviously not desirable, so the following filters are provided to force a meta cache update:
hestia_ancestors_preload_meta
hestia_attachments_preload_meta
hestia_children_preload_meta
hestia_siblings_preload_meta
hestia_sitemap_preload_meta
Return true
to any of these and all post meta will be loaded in a single query up front rather than a query per post.
Caching
No caching is done by this plugin.
For the most part, these shortcodes run very basic queries and you should not notice any performance impact.
The possible exception is the sitemap shortcode which runs AT LEAST two queries per public post type.
If you have a large number of post types I do not recommend using the sitemap shortcode without a solid caching strategy in place.
