Do i need to pass all the hidden fields as well with the form in scrapy
Sometimes you can go without some of the hidden fields, other times - not.
You cannot know the server logic. It's up to the website how it is handling each of the form fields.
I want to know that if i need to perform some search on the job site , then do i need to pass only those variables which are visible on the form or all the variables , even some hidden fields like
The form is here  http://www.example.com/search.php
Now there are two fields on the form like   searchTerm and area  and there are 5 hidden fields
The form submits to  http://www.example.com/submit.php
Now i have these doubts

Do i need to open the form page with scrapy with form page url or with the post url
DO i need to pass the hidden variables as well or they will automatically gets posted with the form
