In my phone website I have maintained in one table linking between seller and buyer. I want that one page should be developed for chatting where seller will see all [url removed, login to view] that 1buyer per row. so when seller want to chat with specific buyer he will click on that buyer name. just like freelancer chat portal at Android. This page should be mobile friendly. on chat user should be able to attach all kind of file he want like jpg, video etc. sample view should be like attached.
