Under /app/code/community/Fishpig/Wordpress/Model, you should find some files including these fields.
- Post.php accesses post data
- User.php accesses author data
- Term.php accesses category data
From your description, most of the information you're looking for will be in Post.php and User.php
Examples:
From the post view and any other pages with access to the post class, you can use these:
$post->getPostTitle() // Post's display name
$post->getPostDate() // Post's date
$post->getAuthor() // Post's author, allows access to methods in the User.php file
$post->getAuthor()->getFirstName() // Author's first name from Wordpress
$post->getAuthor()->getGravatarUrl() // The url to the author's Gravatar image
$post->getParentTerm('category') // Post's category, allows access to methods in the Term.php file
$post->getParentTerm('category')->getUrl() // Category's url
$post->getParentTerm('category')->getPostCount() // Total number of posts in the category
From the user view and any other pages with access to the user class directly, you can use these:
$author->getFirstName()
$author->getGravatarUrl()
From the term / category views and any other pages with access to the term class directly:
$term->getUrl()
$term->getPostCount()
