Paypal return URL - using GET parameters?

问题

Here's some simple code I'm using to test the Paypal Website Payments Standard upload thingy.

My return URL is http://mysite/index.php?module=store&show=order_confirm I go through the payment process, and when I get to the end and it returns me to the page, it instead just returns me to index.php (i.e. without the extra parameters).

Anyone know what the deal with this is

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

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

    <input type="hidden" name="upload" value="1">
    <input type="hidden" name="return" value="http://mysite/index.php?module=store&amp;show=order_confirm" />
    <input type="hidden" name="currency_code" value="EUR" />

    <input type="hidden" name="business" value="b.coug_1277121937_biz@gmail.com">

            <input type="hidden" name="item_name_1" value="adaddada" />
            <input type="hidden" name="amount_1" value="30.00" />

            <input type="hidden" name="quantity_1" value="1" />
                            <input type="hidden" name="item_name_2" value="wuiui" />
            <input type="hidden" name="amount_2" value="50.00" />
            <input type="hidden" name="quantity_2" value="1" />


    <input type="hidden" name="custom" value="19" />

</form>

I'm not sure why Paypal is doing what it's doing, but I suspect their desire to add their own GET parameters is wiping out your own. You might want to try something like this, if mod_rewrite or something similar is available to you:

write a rule that changes this:

http://mysite/store/order_confirm/?merchant_return_link=Test+Store

to this

http://mysite/index.php?merchant_return_link=Test+Store&module=store&show=order_confirm

Try escaping the ? and & in the return URL; change them to %3F and %26.

An alternative answer is to set the paypal 'rm' [return method] variable to "2", so that paypal would POST all its own return variables, rather than sending them as GET variables
