I've seen a lot of posts on Paypal, but has anyone done Google Checkout integration on ZenPhoto yet?

Never heard of that. What is that for?

I have not seen Google Checkout integration yet, but I'd imagine one could mod the Paypal plugin to get it to also work with Google Checkout.

All that is needed is to have a definition of the form that is used by the Google Checkout. The Paypal plugin is a good start for modifications, but I would suggest cloning into a Google plugin rather than trying to make one version that does both services.

I found this: http://code.google.com/apis/checkout/
Does that help?

Yea, you found exactly what you will need to make the plugin

Do you have a Google Merchant ID? It looks pretty simple to make this implementation, but I have no way to test it.

I have placed an experimental Googal Checkout plugin in the nightly build. I have not tested it as I do not have a merchant ID. Please give it a try and provide feedback.

Okey doke,
I've been trying to get the plugin to work, but the plugins page gives me these errors (and won't let me activate the plugin).

You need to delete all the files in your /zp-core/plugins directory and re-install the nightly build...

We need to fix this for the next version I think, so it won't be a problem, but for now that should work.

These files actually should not be in the nightly anymore...

Alright. I replaced the /zp-core/plugins directory with the one from the May 3rd nightly build, and that took away the errors in the plugins admin page.

Now, however, I get two errors when looking at an image:

This one shows up at the top, above the breadcrumb.

Warning: Invalid argument supplied for foreach() in /home/content/b/j/a/bjancewicz/html/ZenPhoto/zp-core/template-functions.php on line 177

This one is at the bottom, where the comment field used to be (it disappeared).

Fatal error: Call to undefined function printImageMap() in /home/content/b/j/a/bjancewicz/html/ZenPhoto/themes/default/image.php on line 62

You can see this in action here:

The Image map is now part of the google maps plugin instead of being within the template-functions. You need to activate that plugin to use this.

Anyway it's recommended not just to replace one folder but to update the whole installation.

Sorry, I mis-read trisweb's instructions.
Ok. I've reinstalled everything except the Themes folder, and the errors persist.
Do I need to customize my theme from scratch? Are there new things in the theme that are causing the error?

ImageMap is part of the plugin google maps. You have to activate it on the options plugin tab first to use it. If you don't want to use it delete it from your theme or place if(function_exists("printImageMap") { printImageMap(); around it.

I do have the Google Maps plugin enabled.

I inserted what you gave me in the image.php file of the theme, so that it looks like this:

I have a typo in my code (I thought you know a few things about php...). Before the "{" there needs to be a ")".

...I know how to make an include, that's about it!
I can design circles around anyone, but I'm a novice when it comes to code. Trying to figure out ZenPhoto is probably the most indepth "training" I've ever had.

I fixed the code so that it reads: ``

I still get errors, though... this one in Gallery view: Warning: Invalid argument supplied for foreach() in /home/content/b/j/a/bjancewicz/html/ZenPhoto/zp-core/template-functions.php on line 177

This one in image view: Parse error: syntax error, unexpected $end in /home/content/b/j/a/bjancewicz/html/ZenPhoto/themes/default/image.php on line 118

The code is still wrong, but my fault again, I forgot another bracket.....:-))
Here finally the right one: ``

You sure?

I still get these errors:

Parse error: syntax error, unexpected '}' in /home/content/b/j/a/bjancewicz/html/ZenPhoto/themes/default/image.php on line 62

Warning: Invalid argument supplied for foreach() in /home/content/b/j/a/bjancewicz/html/ZenPhoto/zp-core/template-functions.php on line 177

I was just judging from the one line I posted and that itself is (now) correct. I don't know of couse what else code you have in your image.php. Please check if all brackets are closed and if there is not one too much.
