amp_is_canonical

Description #

Whether this is in 'canonical mode'.

Themes can register support for this with add_theme_support( AMP_Theme_Support::SLUG ):

add_theme_support( AMP_Theme_Support::SLUG );Code language: PHP (php)

This will serve templates in AMP-first, allowing you to use AMP components in your theme templates.
If you want to make available in transitional mode, where templates are served in AMP or non-AMP documents, do:

add_theme_support( AMP_Theme_Support::SLUG, array(
    'paired' => true,
) );Code language: PHP (php)

Transitional mode is also implied if you define a template_dir:

add_theme_support( AMP_Theme_Support::SLUG, array(
    'template_dir' => 'amp',
) );Code language: PHP (php)

If you want to have AMP-specific templates in addition to serving AMP-first, do:

add_theme_support( AMP_Theme_Support::SLUG, array(
    'paired'       => false,
    'template_dir' => 'amp',
) );Code language: PHP (php)
