We have a requirement where we need few pages to be hosted from a SharePoint site collection and from those pages we have a form to collect data from Users.
On click of submit the data should be saved in the SharePoint list which resides in the same collection where this page is hosted. We do not want to use any webpart for it, at least for now. (Checking whether there are any other easier options)
I have tried the same using SPServices Jquery library, and it works fine. But the problem is this has to be a Anonymous site. After giving anonymous permissions at the web application level, Site collection level, List level, any user is able to open the site. But when trying to submit the form (SPService function is called which in turn uses SharePoint services) Credentials pop up window appears.
Is there a way to make the service work anonymously or is there any other way apart from this. If not is the web part customization possible? (Page is heavily customized)
