Jetpack has the infinite scroll functionality activated by default for archive and blog views. However, it’s turned off for search results views.
Overview
Infinite Scroll includes a filter to indicate if it’s supported or not, and we can use a conditional to alter the returned value. The filter is infinite_scroll_archive_supported and it receives a boolean stating the supported state for the current view and the infinite scroll initialization settings as parameters.
Filtering the current view support
We’ll write a condition similar to the one found in the filter but adding is_search so it kicks in a search results view. You can paste the following in your theme’s functions.php or similar:
/**
* Enables Jetpack's Infinite Scroll in search pages, disables it in product archives
* @return bool
*/
function tr_theme_jetpack_infinite_scroll_supported() {
return current_theme_supports( 'infinite-scroll' ) && ( is_home() || is_archive() || is_search() );
}
add_filter( 'infinite_scroll_archive_supported', 'tr_theme_jetpack_infinite_scroll_supported' );
Disabling Infinite Scroll on custom post type archives
Perhaps you’ve a certain custom post type archive, like WooCommerce products and you want to disable Jetpack’s Infinite Scroll for WooCommerce product shop and archives. This is what you would use then:
/**
* Enables Jetpack's Infinite Scroll in search pages, disables it in product archives
* @return bool
*/
function tr_theme_jetpack_infinite_scroll_supported() {
return current_theme_supports( 'infinite-scroll' ) && ( is_home() || is_archive() || is_search() ) && ! is_post_type_archive( 'product' );
}
add_filter( 'infinite_scroll_archive_supported', 'tr_theme_jetpack_infinite_scroll_supported' );
We’re not using a function like is_woocommerce because if you ever disable the WooCommerce plugin, the site will go blank since the is_woocommerce function will no longer be defined and it will throw a fatal error.
