A regular client has asked me to set up a "logging in" area which will lead to an online store. The logging in area will only be useable by customers that he selects (potentially hundreds), he does not want just anybody to be able to register and gain access (strictly chosen customers only). I redesigned his website last year but I do not host it (I was only given the ftp details and uploaded the new website), I had no need to get to the control panel and never was given the details for it. (I have a feeling that his previous designer is still holding on to the control panel access details, I had to call her in order to get the ftp details when I was approached to redesign his website) Anyway, my question is - how complicated is it to set up a secure logging in area? (providing MySQL is available on his control panel right?). Also, apart from MySQL, will I need any other applications or programmes in order to have this logging in area work? Any recommendations on decent shopping carts? (I am aware of Roman-cart and obviously PayPal) Thanks, much appreciated.
