The below installment viewer supports variable products by WooCommerce internal javascript hook found_variation. If you're interested in this, look in the bottom section.


If your products has options that may change the price on fly, the plugin is using the found_variation hook, which is a WooCommerce hook that detectes changes in the display_price section. This hander is executed when the full page is loaded (onload) and looks like the code below. This is an EXPECTED behaviour for both plugins and WooCommerce, so if this section does not work properly it may be caused by the fact that your custom theme is lacking this support.

As the variable product changes the base price for the product, the plugin will make a backend call to resursbank_get_new_annuity_calculation, which is an AJAX call that only fetches the new price that the WooCommerce hook triggered. So in this case, parts of the "annuity factor string" will change instead of a complete replacement of the html block. Doing this, the part pay price will work seamlessly as the price is embedded in an exclusive element (r_annuity_price) on the page. Building your own custom installment data do support this too, if you use the [payFrom] shortcode.
