fakepath ajax post for uploading files to separate php file

Hi All,
I am trying to ajax upload some files as part of a fluid process in the interface. Various things happen to the text file later etc..

I realise that a POST works. But I want to do as part of my ajax with other field information so that I can execute MySQL statements also etc.. etc..

First time I have done through ajax and there is a lot of information out there and numerous multi step procedures ....but cannot follow.

Please can you help me understand what to change so I actually upload the file. I do not need to see the path at all.. but obviously need it for the uploader the other side.

Using:

    var file = document.getElementById("myfilefield").files[0]; //JUST filename.
    var file = document.getElementById("myfilefield").value; // FAKEPATH in path.

Select allOpen in new window

I push this into an array with a some various text like user, reference etc.... It is an array as I may do up to 10x at once in the entire process of uploading, interpreting and storing data from the file

but of course the POST is c:\fakepath so my upload fails.

Please advise.

Many thanks in advance
