We’re using MyCred to sell services like jobs opportunities, publishing articles, publishing ads, etc.
We saw that your plugin blocks content for custom post types. But what we need is to sell the ‘publish’ or ‘upload’ a new post, job, etc. Not the content itself.
So, we made a specific page for the ‘new ad’ form, and set it a credit price. But the problem we see with this, is that once the user ‘buy’ with the credits, he can upload as many ads as he/she wants. And the only way to filter this is to set an ‘expiration date’ on the purchase. Is there a hook or something to only allow one post to the user to publish, and then when he does, ask for the payment again?
