Once you have that installed and working I have found a way to apply the discount to certain products only and not the entire cart...
so for example a store sells different wines such as chenin, shiraz, cabernet etc etc
firstly here is an example of your product html page with ID_NUM value in this case Chen Blanc Case is CBCA
- Code: Select all
<input type="hidden" name="ID_NUM" value="CBCA">
You will want to modify your nopcart discount mod to the following
under
- Code: Select all
function addCoupon(coupon,fTotal,iNumberOrdered){
place in the following so that it loops through your cookie
- Code: Select all
var iNumberOrdered = 0;
iNumberOrdered = GetCookie("NumberOrdered");
if ( iNumberOrdered == null )
iNumberOrdered = 0;
for ( i = 1; i <= iNumberOrdered; i++ ) {
even = Math.round(i/2);
NewOrder = "Order." + i;
database = "";
database = GetCookie(NewOrder);
Token0 = database.indexOf("|", 0);
Token1 = database.indexOf("|", Token0+1);
Token2 = database.indexOf("|", Token1+1);
Token3 = database.indexOf("|", Token2+1);
Token4 = database.indexOf("|", Token3+1);
fields = new Array;
fields[0] = database.substring( 0, Token0 );
fields[1] = database.substring( Token0+1, Token1 );
fields[2] = database.substring( Token1+1, Token2 );
fields[3] = database.substring( Token2+1, Token3 );
fields[4] = database.substring( Token3+1, Token4 );
fields[5] = database.substring( Token4+1, database.length );
now add in your if statement based on the product ID that you set on your html page
- Code: Select all
//if coupon code = CHENINCASE and product id = CBCA (Chenin Blanc Case) then take off $20
if (coupon=="CHENINCASE" && fields[0]== "CBCA"){
validcoupon = true;
myInt = -20;
fTotal -= myInt;
strPRICE = myInt;
strNAME ="$20 Off Coupon Chenin Blanc Case Only";
}
then leave this all the same
- Code: Select all
if (validcoupon){
iNumberOrdered++;
strID_NUM = "Discount";
strQUANTITY = "1";
strSHIPPING = "0";
strADDTLINFO = "0";
dbUpdatedOrder = strID_NUM + "|" +
strQUANTITY + "|" +
strPRICE + "|" +
strNAME + "|" +
strSHIPPING + "|" +
strADDTLINFO;
strNewOrder = "Order." + iNumberOrdered;
SetCookie(strNewOrder, dbUpdatedOrder, null, "/");
SetCookie("NumberOrdered", iNumberOrdered, null, "/");
alert("Discount added: \n-------------------------------------\n" + strNAME)
location.href=location.href;
} else {
alert("I'm sorry, that coupon code is invalid. Please try another code.");
}
}
So it should look like as a whole
- Code: Select all
function addCoupon(coupon,fTotal,iNumberOrdered){
var iNumberOrdered = 0;
iNumberOrdered = GetCookie("NumberOrdered");
if ( iNumberOrdered == null )
iNumberOrdered = 0;
for ( i = 1; i <= iNumberOrdered; i++ ) {
even = Math.round(i/2);
NewOrder = "Order." + i;
database = "";
database = GetCookie(NewOrder);
Token0 = database.indexOf("|", 0);
Token1 = database.indexOf("|", Token0+1);
Token2 = database.indexOf("|", Token1+1);
Token3 = database.indexOf("|", Token2+1);
Token4 = database.indexOf("|", Token3+1);
fields = new Array;
fields[0] = database.substring( 0, Token0 );
fields[1] = database.substring( Token0+1, Token1 );
fields[2] = database.substring( Token1+1, Token2 );
fields[3] = database.substring( Token2+1, Token3 );
fields[4] = database.substring( Token3+1, Token4 );
fields[5] = database.substring( Token4+1, database.length );
//if coupon code = CHENINCASE and product id = CBCA (Chenin Blanc Case) then take off $20
if (coupon=="CHENINCASE" && fields[0]== "CBCA"){
validcoupon = true;
myInt = -20;
fTotal -= myInt;
strPRICE = myInt;
strNAME ="$20 Off Coupon Chenin Blanc Case Only";
}
}
if (validcoupon){
iNumberOrdered++;
strID_NUM = "Discount";
strQUANTITY = "1";
strSHIPPING = "0";
strADDTLINFO = "0";
dbUpdatedOrder = strID_NUM + "|" +
strQUANTITY + "|" +
strPRICE + "|" +
strNAME + "|" +
strSHIPPING + "|" +
strADDTLINFO;
strNewOrder = "Order." + iNumberOrdered;
SetCookie(strNewOrder, dbUpdatedOrder, null, "/");
SetCookie("NumberOrdered", iNumberOrdered, null, "/");
alert("Discount added: \n-------------------------------------\n" + strNAME)
location.href=location.href;
} else {
alert("I'm sorry, that coupon code is invalid. Please try another code.");
}
}
now you can customize your coupons so that they can only apply to certain items
example:
- Code: Select all
//if coupon code = special and product id = RESERVE and quantity ordered is 6 or more then give a $50 discount
if (coupon=="special" && fields[0]== "RESERVE" && fields[1]>= "6"){
validcoupon = true;
myInt = -50;
fTotal -= myInt;
strPRICE = myInt;
strNAME ="$50 Off Your 6 or more bottles Reserve Order";
}
