Looking for someone to build me a small code, basically take the wordpress updater (ajax) and i want the same just with authentication to the new file (curl maybe?) the process is simple, get file url to download, access it with username/password, download, store in a temp folder, unzip it, override old files, delete the temp file. this should be cheap work to anyone who knows what he's doing, and most of all, I want complete code with wordpress core functions. This should be ajax compatible so I can connect it later to wp ajax functions. the data of username password will be submited via ajax form, also that data should be stored for later use so user wont have to enter it twice (in your case might think also of integrating a cookie into the process). give me your prices via PM.
You're wrong if you think this is going to be cheap. Be aware if you get a cheap quote - it'll be a scam. Good luck ^^
