Specify a return url based on items in cart

Specify a return url based on items in cart

I would like to specify a return url to go to if there is a specific item in the cart. For example, the standard return url would be 'complete.php', but if there is an item of ID 1 for example in the cart I would like the return url to be complete2.php. I'm using PayPal.

Is this possible?

i have never tried it, but it should be possible.

On confirm.php you have a hidden field called return which is passed to paypal.

set this value to a session variable, which will have the return page url

by default, this session variable could be set to the standard return page.
if the specific item is added to the cart, change the session variable to the alternate page url,

Sounds like that should work! I'll give it a go.

Thank you!

good luck with that.

i just thought, you would also need to check if the 'special' item is removed from the cart

OK, I've created a session value in the way you've suggested and called it 'returnurl'. I've give it a value of the page I want to be the default redirect page. I've set the trigger as 'If Session Variable Is Not Defined'.

I've added this to the hidden field like this:

<input name="return" type="hidden" id="return" value="<?php echo $_SESSION['returnurl']; ?>" />

Can you advise how I would go about changing the value of the variable if a specific item is added to the cart?

Thanks again.

Use the following code to check for Item ID 1 in the cart and change the value of the session:

php:
<?php

if($<Your Cart Name>->InCart("1") == true) {
  
$_SESSION['returnurl'] = "complete2.php";
}
?>




change <Your Cart Name> to the name of your eCart object.

Ok.

Firstly, test what you have done so far, to show that the session variable is being set and that the return works properly.

If this is OK, then step 2 needs a little bit of thought. (I haven't used ecart for a few months - if I don't get this right, perhaps someone from Webassist can step in)

From what i recall, there is a block of code on the cart page like this...

while (!$YOURCARTNAME->EOF()) were YOURCARTNAME is whatever you called your cart instance.

I think this is where the code loops through the cart array and sends it to the page

I think the best thing, is to do some 'if' statements within this loop, to check if the product id you are looking for is in the cart.

if it is, set a variable to true or something like that.

outside of this loop, test for true, and then set the session variable accordingly.

without looking at it in detail, i am guessing a bit, so i hope i don't led you astray.

Hopefully on of the WA guys can come in here too and advise.

Hope this helps


** What do you know, Jason got in there before me with what looks like an easier solution **

Thanks Jason
