A few more PHP questions from me. :0)

Password Encryption - Have a for that allows users to register, need some way of encrypting the passwords though, is there a built in function with php to do it or would I need to write one to do it? Also you know when you enter passwords in forms they you get **** instead of the characters being entered - how do you do that?

Sessions - How tricky is using sessions in php? Need to make sure that only registered users can access certain parts of my site, is it something that is going to take a while to do or is it straightforward enough to do?


Cheers

Looking for some help.
I'm struggling to find a way of changing a date. What I need is a variable that holds todays date, using:
$dateCreated = Date('y-m-d');

I also want something that stores the date 30 days from todays date but what I've tried so far just fails.

Anyone know how to do this?

Thanks

Had a bit more of a think about it. Pretty sure I can use the GET method and just pass some info about each one in the URL to a standard rating page.
Just need to work out exactly how to do it.

EDIT: Managed to get it working now. Glad that bit is done.

Something else that I aint to sure on.

I am displaying a table, it shows information about films such as their name, etc. I want people to be able to submit a rating for each film and then I calculate an average for each.
First thought was that I'd have to create a page for each film to allow a rating to be made for each film.

Then I wondered if it would be possible to add an extra column to the table of all the films and have a link at the end to provide a rating.

The table is created by using a loop to loop through the database and while there is still rows in the table display the data I wish to show.

Thing is I am not sure how or if this way would be possible? Just not sure how to set it up so that when I click the rate link at the end of a row it would apply to that particular film.

Any pointers as to how it could be done or to a better suggestion?

I expect it is because you're using something like if ($loggedin == true) without the isset function.

Back to the register globals area, variables have to be predefined before being used in a script by default. As someone isn't logged it, I expect that the $loggedin variable hasn't been created anywhere else previously.

If this is the case, try using if (isset($loggedin) && $loggin == true) in place of if ($loggedin == true). Or, if you're searching for the loggedin variable from within a session, if (isset($_SESSION['loggedin']) && $_SESSION['loggin'] == true)

Quick question about sessions.

Using sessions to check if someone is logged into a site for the various pages. If they are logged in then it displays the content, if not it returns an error.

If someone views a page (ie types in the url for it) and they are not logged in then this message comes up before my error message

Notice: Undefined index: loggedin in C:\Server\htdocs\Project\browse.php on line 4

Should that come up or is there a way to get rid of that and only show my error message that I want displayed?
Cheers

Here's a riddle for you: "Up own his Turbonutter ass is" - solve that!

Quick aside. If you're passing a MD5 password to compare to a one stored in a mySQL server, I found that the following worked:-

Update user set password = password(md5()) where username = ""
