Built-in Shortcodes

Inside LiveCanvas, as in standard WordPress posts and pages, you can use shortcodes to implement dynamic parts ("PHP code").

The LiveCanvas plugin defines some extremely barebone but powerful shortcodes to simplify your work and get you started quicker.

lc_nav_menu

This shortcode calls the WordPress wp_nav_menu function, passing all shortcode parameters.

It can be used for including the navigation in your header, or wherever you want.

Accepted parameters and default values:

'theme_location' => 'primary',
'container_class' => '',
'container_id' => '',
'menu_class' => '', //TO THE UL
'fallback_cb' => '',
'menu_id' => '',
'depth' => 2,
'walker' => $the_walker,

It is using as a default walker function:

  • the bootstrap_5_wp_nav_menu_walker class, if defined, for Bootstrap 5 support (eg for Picostrap5 theme support)
  • the WP_Bootstrap_Navwalker class, if defined, for Bootstrap 4 support (eg for Picostrap4 theme support)
  • the Understrap_WP_Bootstrap_Navwalker class, if defined, for UnderStrap theme support.

Example

lc_nav_menu theme_location="primary" container_class="" container_id="" menu_class="navbar-nav"

 

lc_home_url

This shortcode calls the WordPress home_url function.

It's typical use case is in a custom header, to link the logo to the site's homepage.

No parameters are allowed.

 

lc_get_posts

This shortcode calls the WordPress get_posts function, passing all shortcode parameters.

It can be used for displaying a list of posts of any custom post type.

The simplest use case could be when you want to show a listing of your most recent blog posts in your homepage.

It allows also for custom callback functions, so you can precisely decide how your posts should be rendered.
