贝宝：单击表单提交按钮后不久的购物车会话为空

Question

How can I delete the cart session soon after the submit button is clicked to send the form data to paypal?

For instance,

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">

<input type="hidden" name="item_name_1" value="Book 1" />

...

<button type="submit" name="submit">Check Out</button>

</form>

And I need to run this script to empty the cart,

unset($_SESSION[SESSION_CART]);
unset($cart);

It seems that it only can be done in javascript's ajax? What about just http or php?

Answer 1

If I were you, I'd empty the cart upon re-directing to your site after the transaction was completed - that way if it gets aborted (eg. the user wants to delete/add something) they can do with less fuss!

However, if you want to delete everything - then you need to POST the form to a page on your website, and then re-POST the data to PayPal
