I like paypal cart over google cart and now you can make your own promotion codes for paypal cart. I use the code below and it works great. If you are worried about security you can place the script in a .js file and secure the include folder. I hope this helps out some of you useing paypal carts.
Code:<script type="text/javascript"> <!-- var discnt = 0; // no default percent discount var coupons = new Array ( // place to put coupon codes "coup1", // 1st coupon value - comma seperated "coup2", // 2nd coupon value - add all you want "coup3" // 3rd coupon value ); var coupdc = new Array ( // place to put discounts for coupon vals 5, 10, 15 ); var coupval = "(blanket)"; // what user entered as coupon code function ChkCoup () { // check user coupon entry var i; discnt = 0; // assume the worst for (i=0; i<coupons.length; i++) { if (coupval == coupons[i]) { discnt = coupdc[i]; // remember the discount amt alert ("This is a valid promo code! \n\n" + "$" + discnt + " discount now in effect."); return; } } alert ("'" + coupval + "' is not a valid promo code!"); } function Dollar (val) { // force to valid dollar amount var str,pos,rnd=0; if (val < .995) rnd = 1; // for old Netscape browsers str = escape (val*1.0 + 0.005001 + rnd); // float, round, escape pos = str.indexOf ("."); if (pos > 0) str = str.substring (rnd, pos + 3); return str; } function ReadForm (obj1) { // apply the discount var amt,des; amt = obj1.baseamt.value*1.0; // base amount des = obj1.basedes.value; // base description if (discnt > 0) { // only if discount is active amt = Dollar (amt - discnt); des = des + ", " + "$" + discnt + "dis, COUP = " + coupval; } obj1.amount.value = Dollar (amt); obj1.item_name.value = des; } //--> </script> </head> <body> <form action="https://www.paypal.com/cgi-bin/webscr" method="post" onsubmit="this.target = 'paypal'; return ReadForm (this);"> <p> <input type="hidden" name="cmd" value="_cart" /> <input type="hidden" name="add" value="1" /> <input type="hidden" name="business" value="Emailaddress.com" /> <input type="hidden" name="item_name" value="Item Name" /> <input type="hidden" name="amount" value="000.00" /> <input type="hidden" name="currency_code" value="USD" /> <input type="hidden" name="no_shipping" value="2" /> <input type="hidden" name="no_note" value="1" /> <input type="hidden" name="lc" value="US"> <input type="hidden" name="bn" value="PP-ShopCartBF"> <!-- Base Price --> <input type="hidden" name="baseamt" value="0.00" /> <!-- Base Discription --> <input type="hidden" name="basedes" value="4VAB-EV1 @369.99" /> Enter Coupon code: <input type = "text" size = "10" name = "coupcode"; /> <input type="button" value="Varify Promo" onclick="coupval = this.form.coupcode.value; ChkCoup();" /> <br /><br /> <!--Page Contents--> Input quantity > <input type="text" name="quantity" value="1" size="4" /> <input type="image" src="addcart.gif" name="submit" alt="cart add" /> </p> </form>
