GoFuckYourself.com - Adult Webmaster Forum - Tech Help with some Javascript PayPal related.

I accept PayPal on my website and I would like to provide a coupon code for certain persons. As I understand it PayPal don't offer this directly through their website but it is possible.

I found this website https://www.paypal-knowledge.com/inf...1512&actp=LIST

Which says you can add the following code into the custom field (on PayPal)

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 ("Valid coupon number! \n\n" + discnt +

"% discount now in effect.");

return;

}

}

alert ("'" + coupval + "' is not a valid 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 - (amt * discnt/100.0));

des = des + ", " + discnt + "% dis, COUP = " + coupval;

}



obj1.amount.value = Dollar (amt);

obj1.item_name.value = des;

}

//-->

</script>

It then say you would add the following code to your website

Code:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" onsubmit="this.target = 'paypal';

return ReadForm (this);">

<input type="hidden" name="cmd" value="_cart" />

<input type="hidden" name="add" value="1" />

<input type="hidden" name="business" value="your_email_goes_here@your_site.com" />

<input type="hidden" name="item_name" value="2nd Item" />

<input type="hidden" name="amount" value="20.00" />

<input type="hidden" name="currency_code" value="USD" />

<input type="hidden" name="baseamt" value="20.00" />

<input type="hidden" name="basedes" value="2nd Item @20.00" />



Enter Coupon code [coup1] &gt;

<input type = "text"

size = "10"

name = "coupcode"; />



<input type="button" value="Check It"

onclick="coupval = this.form.coupcode.value;

ChkCoup();" />



Input quantity &gt;

<input type="text" name="quantity" value="1" size="4" />



<input type="image" src="addcart.gif" name="submit" alt="cart add" />

</form>

I haven't tried this but just need a simple "Pay Now" button that offers people the chance to input a code into a text field for a discount to be applied.
I tried the code in an online HTM viewer and it looked naff.

Anyone tell me if this is at all suitable for 2017 or can give me a better suggestion / code.
