Bypassing the server check of form input

Web developer services are required. A form entry server check is required. On Zen, an iframe video from Yandex ether is inserted, I need to make sure that when a person opens an article, the video reproduces itself. It's the article that needs to be built into. You need to change this iFram any way you want or do something different. But it's in the article, not in the video. I can describe all the additional details in a personal conversation. Payment after the order is executed - we agree on the place at the cost. No prepayment, no contracts - safe deal or guarantor.
If you don’t have a Zen/Yandex account, I’ll give it to you. If you have one, it doesn’t matter if it’s my account or yours.
Yandex has already blocked some ways of autoplay - the essence is that the video would turn on itself.
