After a deep search I created a WooCommerce shortcode. The purpose of this is to display a "Buy X more products to get a discount" message.
My code:
add_shortcode('check', 'custommessage');
function custommessage() {
$items_count = WC()->cart->get_cart_contents_count();
$min_count = 6;
if( $items_count < $min_count ){
echo sprintf('%s products more for discount' , $min_count - $items_count );
}
}
On WooComerce cart page, after adding X products to the cart or removing the quantity it works and refreshes automatically the message
But when I put the shortcode (on side cart) it does not auto refresh the X count. Although it is also AJAX driven.
Any advice how i can solve this?
To ajaxify your message so it updates when an item is added/removed (via ajax) use the woocommerce_add_to_cart_fragments filter hook
So you get:
function custom_message() {
// Initialize
$message = __( 'Default message', 'woocommerce' );
// True
if ( WC()->cart ) {
// Get number of items in the cart.
$items_count = WC()->cart->get_cart_contents_count();
$min_count = 6;
if ( $items_count < $min_count ) {
$message = sprintf( __( '%s products more for discount', 'woocommerce' ), $min_count - $items_count );
} else {
$message = __( 'Some message', 'woocommerce' );
}
}
return $message;
}
// Refreshing on cart ajax events
function filter_woocommerce_add_to_cart_fragments( $fragments ) {
$fragments['div.display-message'] = '<div class="display-message">' . custom_message() . '</div>';
return $fragments;
}
add_filter( 'woocommerce_add_to_cart_fragments', 'filter_woocommerce_add_to_cart_fragments', 10, 1 );
1) Then to display this via a shortcode, use:
function display_my_message() {
return '<div class="display-message">' . custom_message() . '</div>';
}
// Register shortcode
add_shortcode( 'display_message', 'display_my_message' );
SHORTCODE USAGE
In an existing page:
[display_message]Or in PHP:
echo do_shortcode("[display_message]");
OR
2) To display the message via any desired hook (in this example I show 2 hooks. 1 on the cart page and 1 on the single product page, adapt to your needs). Use:
// Display message via the desired hooks
function display_message() {
echo '<div class="display-message">' . custom_message() . '</div>';
}
add_action( 'woocommerce_before_shop_loop', 'display_message', 10, 0 );
add_action( 'woocommerce_before_add_to_cart_form', 'display_message', 10, 0 );
