Question

symfony

Hello. The crawler docs say that you need to find exactly the form on the page, and add values ​​​​to the fields there and send it. But if there is no tag on the page? There are only two fields <input type="text">and one more field in the form of a button <input type="button">. How should I proceed in such a case? How to enter data in the field and click on the button?
