Advanced Mysql / PHP database backed login script

[prydie]

I conformed to popular demand and did a version 1.2 of my login script. Its new features include md5 encryption and the use of a database instead of variables stored in the script.

ummm.. Toon, you give me sh*t about writing 2 page tutorials that directly relate to questions that people actually ask here. Hmmmmph, I better not hear another peep from you on that, brother

[Toon]

Yeah but linking to them from here is too easy, it will never make your site popular you both have to realize the web is full of the same tutorials, what makes yours and your site better than the rest?

It looks to me, like you have laid your self wide open to an SQL injection attack. I would suggest you rethink your approach.

Were do you suggest that there is sql injection? There is only one query and that has addslashes on the only user inputed variable.

I'm sorry , but the addslashes class doesn't afford you any protection against SQL injection attacks. You have to detect malicious user input pro-actively using advanced error rejection exception techniques, or regular expression string rejection constructs.

I advocate high security coding but I was trying to write a simple script for beginners to learn from. I suppose mysql_real_escape_string() could have been used but add slashes gives us the security we need here. I can't see any way to inject it but you are welcome to try. I will send it across to one of my mates in the security field and see what they think but I am confident that there is no means of exploiting the script.

any chance of seeing your version with the member registration bro?

[prydie]

I will be posting it soon. I have got registration going but need to make sure that its all working properly and is totally secure.

Thanks for the interest

I will post a thread about version 1.3 when I release it.
