One-Page Checkout [Support Thread]

[fjbern1943]

Frank, the checkout_process functionality is untouched by the One-Page Checkout's processing. There might be, however, some changes that your application introduced into the checkout_payment/confirmation processing that are not getting picked up.

Are there any observer-class (i.e. /includes/classes/observers) modules that "help" with the operation? Or any additional header_php_xxxx.php files present in the /includes/modules/pages/checkout_payment or /includes/modules/pages/checkout_confirmation folders?

There aren't any additional header.php files or observers that I am aware of or can find but the vendor application does modify the checkout payment, process, shipping and confirmation pages. That should explain why the vendor application works with standard checkout process and not the one page checkout. I will try to merge these changes with the one page checkout files. I will let you know I make out.

Thanks for jogging my memory

Darn it, another bug, this one occurs if the customer's applied a discount coupon to their order and then updated their shipping-method.

When that happens, a debug log similar to:

Call to a member function bindVars() on null in /dir_fs_catalog/classes/ajax/zcAjaxOnePageCheckout.php on line 34

gets generated.

The correction's simple: edit /includes/classes/ajax/zcAjaxOnePageCheckout.php (line 20), adding the $db to the list of globally-referenced variables:

        // -----
        // Since we're running as a function, need to declare the objects we're instantiating here, for use by the various classes
        // involved in creating the order's total-block.
        //
        global $db, $order, $currencies, $checkout_one, $total_weight, $total_count, $discount_coupon;
        global $shipping_weight, $uninsurable_value, $shipping_quoted, $shipping_num_boxes, $current_page_base, $current_page, $template;

As far as I can see there is no file correlation between my vendor application and one-page checkout.

The below code is from my existing checkout_confirmation.php page. Please note the two instances of MVS Start and End code. I think that this is the code I need to add to the one-page checkout plugin.

It looks like the I need to modify the modules/pages/checkout_confirmation/header_php.php file to incorporate these changes.

Am I on the right track? Can you help me in making these changes?

Thanks,

Frank, just so I understand ... you've got an application that runs separately from the "normal" storefront, i.e. you access that application as https://www.example.com/application_name.php (where the application_name.php file is in the root directory of your store)?

[fjbern1943]

Hello Again, Thanks for the response.

The answer to your question is NO. In addition to the core files for this application there are also over writes of some of the store standard files.

The way this works is after the order is confirmed the order information is stored in the database in the normal manner but also stored as an order associated with a particular vendor.

Then the admin can access the order and the associated vendor order and is shown as an order associated with a particular vendor. At that point you can elect to have the vendor order sent automatically or manually to the vendor via email with a copy of the packing slip.

The only part of the application, that I can tell, that is not being passed by one-page checkout is the MVS stuff (Vendor Shipping) in the file above.

So I think that if there is no vendor shipping associated with the order then the application does not recognize it as vendor order. Just a presumption on my part since I did not write the application, done by third party, which I believe was a modification and ##############ization of the old zencart plugin, MVS with PDF.

I hope that explains things a little. If you need any additional information, please let me know.

Frank

@fjbern1943, I'm still not getting it. Is this "application" something that gets invoked by your Zen Cart's admin-console after the customer has placed the order?

Hello,

Every product is associated with a particular vendor. When a customer orders a product the information is not only registered in the database as an order in the regular way but is also associated with that particular vendor. After the order and vendor information is written to the database in the backend the order with packing slip is sent to the vendor again either automatically or by sending it manually in the admin by pushing a button.. This can be set in the vendor setup. Everything is drop shipped by the vendor, I do not normally carry any inventory.

This allows me to automate the ordering process with my vendors. Otherwise, I would have to send them an order by email manually. This was setup with the expectation that there would be a lot of orders to enter daily. I hope this helps to clarify what the application does and how it is used.

Frank, since the code you posted in post#55 starts by loading application_top.php and ends by loading application_bottom.php, I've got to assume that the script either runs under the admin or is stand-alone running from the root of your store-front.

The only thing that I can think of that might work is for that script to have its own auto-load "prefix" so that the one-page checkout doesn't interfere with that after-order script.

First, copy the file /includes/auto_loaders/config.core.php to a file named mvs.core.php in the same folder. Next, modify that script you posted, adding the following statement just prior to the require for the application_top.php script:

$loaderPrefix = 'mvs';

That will result in that script processing like the one-page checkout wasn't in the picture since its observer won't be loaded due to the change in that loader-prefix value.

Hello,
First let me thank you very much, especially since this is away off topic for this thread.

I will give this a try and see how I make out. Seems like a very reasonable approach.
