Hello, I’m using a very simple software that allows you to create online surveys. The software uses a database in php and mysql. The problem of the script is that among its functions can prevent users from sending more than once, the answers to the same survey, but does not work. Even if the option is selected, each user can send unlimited times the answers to the survey and I want this not to happen.
In attachment you can download the software, the installation guide and a picture showing where to select the option to prevent the continuous posting of the survey responses but does not work. The software is in Italian but using a translator is easy to see how it works. If you asked a question other contact me
