Dave,
Thank you for your very helpful and quick response. I have watched the video, but still have another question. One thing I did forget to ask about in the original post is what if the user wants to purchase two packages. Say they want to purchase both (1) Paid Level #1 and (3) Paid Level #3. One the four posts I have made, the tag and category for level #1 is tag: true_value and category slug: true-value. On the post for level #3 tag: real_strategy and the category slug: real-strategy. Would I have to write the php to look for any combination of tags/category slugs so someone who has purchased both would have access to only those two pages?
Also, in creating the PP buttons, the user has already purchased “Paid Level #1” so the button would have the ccap in it of “true_value”. So, I assume in the user profile that “Custom Capabilities” would initially have the value “true_value”. When the user purchases the additional “Paid Level#3”, will the user’s “Custom capabilities” now show “true_value,real_strategy” or will it delete the “true_value” and replace it with “real_strategy”?
Thanks for your help in this. You have been a big help.
