How to implement this feature in wordpress site where it calculates final amount based on options and redirect for payment. If it is possible with any free plugin.
In above screenshot it calculates amount based on DSC type and validity period.
Thanks in advance.
There are form plugins out there, but I’m not aware of any that do calculations outside of being a paid plugin. Gravity Forms usually my go to for forms, but you’d have to buy additional plugins for some of the complicated calculations I’m sure.
