[Plugin: Custom Field Template] Full Documentation

I am planning to make the documentation site but I do not have much time and the cost to support will increase these days. I am sorry to say my complaint…. Anyway, the difference between code and editCode:

code will be executed before displaying the input field in the post edit page. For example you can make the custom select box based on posts or categories.

editCode will be executed before saving the value.

I should show you examples….

Some good info here:

Documentation would be great ! Examples would be perfect ^^
