Maybe it's just me but we seem to be getting a lot of posts from newbies (more than normal) who post vague general questions or dump a whole bunch of code that isn't working and expect someone who knows what they are doing to spend a bunch of time doing something that they may have been too lazy to do for themselves. You don't need to be a php expert to post a question or a problem (probably quite the opposite most of the time). I think that we should expect some effort on their part first to do some research, some testing / debugging and provide a decent statement of the problem / question before they get any help. In many cases, you can do the work to get them an answer and you don't even get a response much less a thank you. Maybe what the internet needs is a global rating of every person for intelligence and as a decent human being. This would follow you around everywhere you go so everyone would know what they are dealing with. Sort of like the DaniWeb + or - ratings for individual posts but on steroids. I am kidding (mostly) but it seems that there are quite a few people who would deserve to be blacklisted on one or both counts.
I am trying configure such as well, I came across this link http://www.daniweb.com/web-development/php/threads/324747/login-form-help which the syntax in the code seems to be wrong first, no biggie...yet I am unable to get anything like this to work...this one just redirects to header and tracks with column 'attempts' or is at least supposed to. However, a timeout would be good too. My current script just states invalid and then link for retry. I have been stuck on this for a while and not sure if I must get out of outher routine in that to make the other enforce in php and I guess timed prevention would need to get ip and put in database and concate to some script to prevent login or something...anyway...hope this is clear enough.
