How to correctly display information from the database through the form in Bitrix?

Question

1C-Bitrix

Guys, welcome. It is necessary to display information from the database through the form in Bitrix. A person indicates the year of birth, gender (m.f) and, based on these data, through a request, display information from the database. In a simple way (I do it using the POST method, not in Bitrix), everything works beautifully. We set the task to do in Bitrix. I know that there it is done in a "special" way. Maybe someone will throw an idea or indicate where to read and look. In fact, I need to somehow read the data entered by the user, I can write a request for a selection. Thanks in advance

Answer 1

It depends on what you need, if the infoblock element data, then

If the block hl data, then

if something else can be found in the documentation

Answer 2

It turns out that regular php commands also work in Bitrix. Implemented the idea. Thanks to all
