Working in a company, which makes use of web applications (php) the page was well developed, but there are small details that could improve the processes, I'm not a developer yet! But I'm studying to become. The page in question presents a small error: if for any reason open two pages (in the same browser), each one with information of a different client and it is necessary to insert some information in the first page, this will be saved in the last page that I access, independent to be the right page.
I hope the situation has cleared up.
Thank you in advance for your attention.
