Note that the function called by the shortcode should never produce an output of any kind. Shortcode functions should return the text that is to be used to replace the shortcode. Producing the output directly will lead to unexpected results. This is similar to the way filter functions should behave, in that they should not produce unexpected side effects from the call since you cannot control when and where they are called from.

Инфы для новичка толком нет нигде

Может быть есть какие-то вспомогательные материалы, библиотеки или готовые решения?
