hi I need to hire someone to do this for me: i want to pass info that is in my link to a button code on my page (so i can track source of my sales) EXAMPLE: my url is http://www.example.com?src=facebook (this is from a facebook ad) so on the page, my BUY NOW link is: http://www.example.com/purchase . how do i dynamically insert >> "?src=facebook" at the end of my url. (so i know this sale came from facebook) my sales tracking system allows passing variable info to it. I am on wordpress, using E-Junkie as my payment processor. I have ALLOW PHP ON PAGE plugin (so php code works on the page) but heard that Java may also be a good option to do what i need here. CODE ON MY PAGE: RED IS MY BUY NOW BUTTON CODE WHERE I NEED TO ADD THE VARIABLE CONTENT Code: <form accept-charset="UTF-8" action="[COLOR=#ff0000]https://www.e-junkie.com/ecom/gb.php?c=cart&cl=XXXXXX&ejc=2"[/COLOR] method="POST" target="ej_ejc"><select name="i"> <option value="">Select Current Option</option> <option value="1449525">Oil Change</option> <option value="1449526">air filter</option> </select> <input class="ec_ejc_thkbx" alt="Buy Now" src="http://mydomain.com/wp-content/uploads/2015/02/buy-now-button5.png" type="image"><img class="alignnone wp-image-615 " src="http://mydomain.com/wp-content/uploads/2015/07/paypal-credit-cards-1.png" alt="Accepted payments types: Paypal, All Major Credit cards, Debit card." width="191" height="73"> PAYMENT VIA PAYPAL.
