Dynamic Price

  1. Hi,
    I want to add this functionality to the form. I want the price per unit to decrease when quantity is increased. I am using products (drop-down) and quantity (drop-down) fields. I have a very simple php if-else condition for this but i am dont know how to integrate this with the form. I have read about using hooks but i failed to use them. Please help me with this. Here is the php statement

    function get_price(baseprice, quantity){
    
          if(quantity ==1)
          {
           total_price = baseprice*quantity;
          }
          else if(quantity>1 && quantity <=10)
          {
           total_price = (baseprice-(baseprice*5/100))*quantity;
          }
          else if(quantity>10 && quantity <=20)
          {
           total_price = (baseprice-(baseprice*10/100))*quantity;
          }
          else if(quantity>20 && quantity <=50)
          {
           total_price = (baseprice-(baseprice*15/100))*quantity;
          }
          else if(quantity>51 && quantity <=100)
          {
           total_price = (baseprice-(baseprice*20/100))*quantity;
          }
          else if(quantity>=101)
          {
           total_price = (baseprice-(baseprice*25/100))*quantity;
          }
          return total_price;
       }

    Can you please tell me how to use this with a hook and where to place the code.
    Thanks.
