Hi Josue,
Thank you for you response! For reference, We’re actually using the WP (REST) API, http://wp-api.org/. My apologies for not providing the link in my initial post. I have a few concerns with your response, specifically regarding the dependence on regular expressions to filter out the shortcode in order to build our JSON obj. This would give us a very hacked and limited approach to building our key value pairs as they make their way from the db to the client side.
Given your response, I’m beginning to assume that this is going to be impossible to accomplish without heavily modifying the Avia Layout Builder. Is this an accurate assumption? Ultimately, all we are looking to do is create a custom layout element in the Avia Layout Builder (we have confirmed that this is possible via a child theme) and modify (customize) the way that this custom element will post it’s content to the database (is this possible?). We’d rather accomplish this by properly extending the plugin as opposed to depending on regular expressions and hacking our way to a solution.
Thank you.
