I've done some changes to the Admin's post creation/ edit form.
It can currently catch previously saved data from the database.
But,
I can't seem to find the page that calls the form's data.
The form is located on "edit-form-advanced.php" and points to "post.php." But, there is no matching words to call the form input names.
How does WP call the form input names to insert the data into the database?
