Advice on how best to integrate a JavaScript spot the ball style competition with eCart

When the user gets to the page (see link below) they will have already selected which product they are playing for, in this case a car. Each car will have a ticket price which entitles the user to one co-ordinates selection. When that selection is made, the details of the co-ordinates should be added to cart along with the ticket price.

It would need to check that the particular co-ordinates were not already in the cart.

What is the best way to approach this as it occurs to me that selecting the co-ordinates should be the 'add to cart' function? I'm not sure how to convert the selection on my sample page to work in this way.

Would appreciate any advice you could offer.
Thank you.

Can two different players have the same coordinates?

I think your existing script could be augmented to make sure the same coordinates aren't picked more than once. Just add unique ID values for your hidden fields and loop through the existing ones to make sure that it wasn't already added.

You could then do the add to cart all at once and do a secondary check as it is actually added.

This might be a good candidate for a premier support ticket. I should be able to help you with the necessary adjustments without much difficulty but it will certainly involve some hand coding both in the client javascript and php.

HI Ray. Thank you for getting back to me on this and I'd be happy to arrange a Premier Support Ticket session to get this sorted out.
When would suit you to do that?

Thank you.

Just fill out the support request on this page: http://www.webassist.com/premier_request.php

Include a good US phone number or Skype contact information and suggest a date and time when you would be available.

Yes.

It would also need to check a users purchase history to ensure that they hadn't already selected a particular set of coordinates during a previous purchase. Would you be able to cover that in our Premium Support Ticket session?

Will just go and book that in with you. Would you be available tomorrow / Wednesday at all?
Thank you Ray.

Ray,

You said, during our last premier support session, that you should be able to help me with a couple of wee changes to the array for the spot the ball selection - namely a way to prevent users from selecting coordinates that they might have selected in a previous purchase.

Firstly though is there an easy way, during the initial selection process, to allow a user to cancel a particular selection?

I've provided FTP and website login credentials below.

I also have a problem with the checkout page. When the user enters their billing address details and clicks "Continue", the "Please Wait" option appears but then it just reloads the checkout page. I assume there must be an error with the save to database or something, but how to do view what that error might be?

Appreciate the help, as ever. Thank you.

We added code to the page that would prevent adding the same spot more than once. It depends on populating an array of previously selected spots. You could create a recordset to look up previous orders and pre-populate that array with the previously purchased values to prevent the same spot from being added by the same person again.

The checkout isn't working because it appears all of the content has been removed from the confirm_cart.php page. Usually when the continue button is pressed on the checkout form, that form is hidden and the confirm_cart page is displayed with a final checkout button. Since the confirm_cart page is blank the process is stalled at that point.

You can probably run the wizard again with new page names to get the necessary content for the confirm_cart page. I'm not sure how or when it was removed.

I would be able to help fix those problems in a premier support ticket if you have difficulty.

I've re-run the wizard and now the checkout page is blank white.
I'm actually completely confused about what's happening at this point as each attempt to run the checkout wizard has failed.
URL and login details are in the post above.

Hope you can help.
Thank you.

EDIT:

Urggh. The Wizard keeps dropping this line into the confirm.php page:
<?php require_once("webassist/ecart/checkout/credentials/gateways.php"); ?>

...yet it doesn't create gateways.php at any stage in the process.

I'm going to try to work through this as much as I can without a premier support ticket as I can't keep resorting to that every time the WebAssist extension decides to throw odd code into a page.

You had mentioned that you'd help me, in the forum, with populating the array with previously selected/purchased spots. I understand that I'll need to create a recordset on the page that calls purchases by that customer, for the same competition, however it also needs to check whether it's for the same car ID.

Hopefully be back to you later but I sense a long night ahead.
Thank you.

It might be easiest to just create a blank page at that location: webassist/ecart/checkout/credentials/gateways.php

That way you don't have to keep deleting the references to it. You must be checking out without payment? It should create that file any time the wizard has a payment gateway selected.

Ray, my Add to Cart button isn't working since I re-ran the checkout page. I've tried fixing it but I can't resolve it. Page is attached.
Is it possible to only have the Add to Cart button displayed when at least one selection has been made?

Also, is there any way to add a link that removes a co-ordinate selection?

Thank you.
