Omzy Posted August 9, 2009 Share Posted August 9, 2009 I use $_SERVER['REMOTE_ADDR'] to get the IP address of the person who fills out my contact form, what other information can I obtain from this IP address and how? For example, country, ISP... Also what other things can I do to improve my contact forms so that I can authenticate form submissions?

nuttycoder Posted August 9, 2009 Share Posted August 9, 2009 you can get all sorts of information from an ip address look at any ip lookup sites http://ip-lookup.net/ Can't see why you need all that for a form submission though. Quote Link to comment Share on other sites More sharing options...

grunshaw Posted August 10, 2009 Share Posted August 10, 2009 I built a control panel for an online radio station and we wanted to track the locations of visitors and also people who used the online form to send in requests. What you could do is log the IP to a database and then build a simple password protected page, grab the IP addresses and use the MaxMind API to view the information you are wanting. The other thing you could do to make them more secure is have a randomly generated code to enter (not a graphic, they suck) like $verify=rand(111111,999999); Send that variable in the from to the next page in a hidden field, and also have a text input asking them to insert that code (which you would echo next to teh nput box) and then compare them on the next page. Makes it less likely that spammers will use the form. Then on the next page, compare the 2 variables to see if the user has inputted the correct code and if so, send the message, if not, error. Hope this helps you. Quote Link to comment Share on other sites More sharing options...
Omzy Posted August 14, 2009 Author Share Posted August 14, 2009 Well I've seen the output from some contact forms which give you the country name and ISP of the sender, how can I do something similar on my contact forms? Quote Link to comment Share on other sites More sharing options...
