This has been edited because I had the wrong tutorial all along. I would like to pinpoint my WordPress posts location in a single Google Map using the Javascript Option V3. I have look all over, but there is nothing that works with the recent version of WordPress 4.2. I don't wanna use a plugin because I would like to have more flexibility later and be able to control all the aspect of the map through PHP. Any help will be appreciated.
I tried the following tutorial Is there a way to display all my posts on a single Google Map? , but no success.
I do believe the above tutorial will be great start though, so if someone can debug it to work with current WordPress version 4.2. That will be much appreciated.
