Hi @Asitis
Ok, it is clear that you don’t understand the docs. Firstly, can you please research WP filters to understand how they work.
The code above shows that you are hooking into the checkbox field. Why did you choose to do this? Shouldn’t you hook into the ‘flexible_content’ field instead?
Next, you have run ‘the_content’ filter on the $value array. Why have you done this? From what you have previously explained, running this filter has nothing to do with your needs.
If this is too much for you, please hire a web developer to help you as I can’t provide free dev support. Only help point you in the right direction and answer specific questions
Thanks
E
