Prefilling forms with POST method and wordpressuser informations

Hello,

I would like to create a form for our current users.

This form would have prefilled fields like Name and Email.

I have seen it is possible using GET method: https://ww.wp.xz.cn/support/topic/prefilling-forms-from-get-variables/

Is it possible to use POST method and wordpress user informations without using GET method ?

Robin,
