It sounds like the search is keying off the wrong info, say a user ID that is hard-coded rather than dynamic. Is this a prebuilt Joomla component/extension or something you wrote? If it’s something someone else built, you’ll have to ask them what’s up. If it’s yours, post the query and a summary of the db structure.
I wrote the PHP scripts myself. I think it was cause I had a web page with 2 forms in it. The first one let them enter their email/pin and then activated a modify script. The second form on the page had them fill everything in, including the email twice. Somehow the action script was using maybe the second email…which could have come from some other user that was entering a new form, while one user was just updating his…maybe that was it, I don’t know…I wrote some code to take care of the second email and blanking it…if you really want to see the code, I’ll post it…it’s pretty simple really.
I thought there were different sessions and stuff…somebody asked how I was doing session security, and I drew a blank…lol…z
