Question

how pass multiple values to paypal. I used it in paypal submission page

<input type="hidden" name="custom" value="id_cart={$id_cart}&option={option}" />

I get

$_POST['custom'] = id_cart=534&option=1620850004 , 

how I get it separately like

 $_POST['id_cart'] =534 , $_POST['option'] =1620850004.

Answer 1

The name attribute on your form fields will become the key server-side, simply break your current hidden field up with new names:

You should also be escaping the values on the page, I’m assuming you’re using smarty…

<input type="hidden" name="id_cart" value="{$id_cart|htmspecialchars}" />
<input type="hidden" name="option" value="{$option|htmspecialchars}" />

If you want / need to keep your HTML the same, you can split the values on the server-side with parse_str:

$r = array();
parse_str($_POST['custom'], $r);

print $r['id_cart'];
print $r['option'];
