Google Checkout module for ZC 1.3.x (beta)

[lhhgbh]

Okay, here are the three shipping modules that I use:

flat550.php
flat650.php
flat1950.php

These are all setup in my cart correctly and located in the same exact folders as the flat.php which comes with ZenCart..

Hi ropu,
As you requested here is my config:
In my shipping module I have only Zone Rates enabled with 3 zones
In payment module -> GoogleCheckout I have:
.htaccess Basic Authentication Mode: false
MultiSocket Shipping Quotes Retrieval: true
Default Values for Real Time Shipping Rates: Zone Rates: default 2.95

Do you need any more info?

Hi blum,
i must say that you should have something wrong.

i double check all, and i dont find any cross reference from gcheckout.php to multisocket.php

The only place that is included is in responsehandler.php line 135 (and only included id multisocket feature is enable. Btw, try disabling it)

And also neither in file 'includes/languages/' . $_SESSION['language'] . '/' .'modules/payment/googlecheckout.php' nor ncludes/modules/payment/googlecheckout.php there is a reference to multisocket.php or responsehandler.php

if gcheckout.php in line 406 is this code

    if ($srv_mode == 'https://sandbox.google.com/checkout/' && $http_mode == 'http') {
        $url = HTTP_SERVER . DIR_WS_CATALOG . 'googlecheckout/responsehandler.php';
    } else {
        $url = HTTPS_SERVER . DIR_WS_CATALOG . 'googlecheckout/responsehandler.php';
    } 

but is used to set up the callback ur, nothing to do with including files.

double check your installation, and address me where you have that cross reference.

tip: search for responsehandler.php multisocket.php in your files to find any inclusion that is out of place.

thx for ur comments

I did a new install over the weekend. I changed the database and directory. I got the same error when I followed the instructions in the installation readme. I decided to use winmerge to compare the files in my template directory to the existing system files for ZC, i.e., the tpl_checkout_payment_default.php, tpl_shopping_cart_default.php and tpl_login_default.php. When I was done, I got the google checkout button to appear without any errors, but now the paypal express checkout button disappeared. I guess it has to do with these files more than anything else. Can you give some guidance here? Would you like me to post the code for these files?

Thanks

At this time I am only accepting google payments. But... when someone goes to checkout they are faced with two checkout buttons how do I hide or get rid of the extra checkout button that goes no where.

Thanks,

Angel

Scratch previous post. I actually messed on the code. forgot to include the paypal code at the bottom of the page. Looks to be working good now. Both options show up. Now I need to move PayPal above google.

have a too to the "..."

this means that you should append the code im sending to the one already there!

any doubt, ask me !

blum, im pretty sure that Paypal overrides GC mods to those templates.

yuo should merge PP and GC templates... i can help you if you want.

PM me with more details. when fixed, we'll post the solution here. Lets avoid posting to much code here that can confuse merchants.

Thanks,

Angel

Angel, you should do two things.

First disable the default checkout button,.

in default installation includes/templates/YOUR_TEMPLATE/templates/tpl_shopping_cart_default.php
line 132

Then in the login page you should also add a redirect to index.php?main_page=shopping_cart this will avoid buyer to enter regular checkout through there.

im pretty sure thats all you need to do.

you can also remove from googlecheckout/gcheckout.php line 521 this code

<td align="right" valign="middle" class = "main">
 <B><?php echo MODULE_PAYMENT_GOOGLECHECKOUT_TEXT_OPTION ?> </B>
</td>

so - Or use - string is not shown
