Installation & Set Up
1. Install the extension using Joomla's Extension Manager, click here for instructions.
2. Enable the extension, go to Admin>>Extensions>>Plugin Manager>>System – Nice Google +1
3. Select the radio button labeled Enabled. Or, for Joomla 1.6 select enabled from the drop down menu.
4. Optionally, enter your desired default Google +1 button size and language.
5. Click the Save button.
Now, the extension is set and ready to go. Let's add a tag to an article and see it in action. Add the following tag to a new Joomla article and click save.
*Important, if you are coping and pasting the example tag to your article, you should paste it into a simple text editor (such as Notepad) first. Then copy it from the text editor to Joomla. This process will clean any hidden HTML code, used for formating, out of the tag. Hidden HTML code can cause the tags to be unrecognizable to the extension and/or cause unexpected results. The best safeguard is to manually type the tag.
After you have placed your tag, take a look at the page from the front end. You should see that the tag has been replaced by either your username (if you are logged in) or by the default Guest Name specified in the plugin's paramters.
That's pretty much all there is to it. Now get out there, add a bunch of Google +1 buttons to your site, and start collecting those valuable button clicks.
Exclude URLs Parameter
In the plugin parameters, you will find the "Exclude URLs" text input field. This parameter allows you to specify URLs that you wish to exclude from the Nice Google +1 button creation process. To add a URL simply specify the full URL of the site page you wish to exclude. Please note that, each URL must appear on a new line.
