If I understand you correctly, you want the popup to show when user clicks on a custom button on a single product page, is that right? Meaning you don’t want the product to be added to cart?
If that’s what you want, drop this code to your theme’s functions.php file.
add_action( 'init', 'remove_popup_trigger' );
function remove_popup_trigger(){
remove_action( 'woocommerce_add_to_cart', 'thp_upsell_popup_trigger' );
}
add_action( 'woocommerce_after_add_to_cart_form', 'my_custom_button' );
function my_custom_button() {
global $product;
$id = $product->get_id();
//here is your custom button
echo '<form id="your-id" method=post>';
echo '<input name="wc-upsell-popup-custom-btn" type="submit" value="Show upsell popup!">';
echo '<input name="wc-upsell-popup-product-id" type="hidden" value="'.$id.'">';
echo '</form>';
}
add_action( 'wp_loaded', 'fire_popup');
function fire_popup() {
if (isset($_POST['wc-upsell-popup-custom-btn'])) {
$prod_id = filter_input( INPUT_POST, 'wc-upsell-popup-product-id', FILTER_SANITIZE_NUMBER_INT );
thp_fire_php_include($prod_id);
}
}
Change the code accordingly to suit your needs.
In case you also want the current product to be added to cart, use the following code instead.
It’s basically the same code as above except that when user clicks the custom button, current product will be added to cart and then the popup will show.
Here’s the code:
add_action( 'init', 'remove_popup_trigger' );
function remove_popup_trigger(){
remove_action( 'woocommerce_add_to_cart', 'thp_upsell_popup_trigger' );
}
add_action( 'woocommerce_after_add_to_cart_form', 'my_custom_button' );
function my_custom_button() {
global $product;
$id = $product->get_id();
//here is your custom button
echo '<form id="your-id" method=post>';
echo '<input name="wc-upsell-popup-custom-btn" type="submit" value="Show upsell popup!">';
echo '<input name="wc-upsell-popup-product-id" type="hidden" value="'.$id.'">';
echo '</form>';
}
add_action( 'wp_loaded', 'fire_popup');
function fire_popup() {
if (isset($_POST['wc-upsell-popup-custom-btn'])) {
$prod_id = filter_input( INPUT_POST, 'wc-upsell-popup-product-id', FILTER_SANITIZE_NUMBER_INT );
WC()->cart->add_to_cart($prod_id); //this line of code adds the current product to cart
thp_fire_php_include($prod_id);
}
}
